HP-8000-NA4-E3 AIR COMPRESSOR GENERAL DESCRIPTION: The HP-8000-NA4-E3 is a four stage, single acting, reciprocating, air cooled unit designed for intermittent or continuous operation. The maximum operating pressure is 5000 PSI. Heat is dissipated after each stage of compression with forced air cooled inter and after cooling lines. Oil and moisture traps collect condensation after the second and third stage cycles. Purification of the produced air is furnished by a filter system of charcoal, desiccant and molecular sieve. PRINCIPLES OF OPERATION: The principle of operation of the compressor operation is that of multistage compression. The air is compressed to the desired pressure in four stages. Air is drawn through the intake filter into the first stage cylinder by action of the first stage piston and valves. There the air is compressed to approximately 60 PSI. This compressed air is then cooled to about 15 degrees above ambient temperature and enters the second stage cylinder where is further compressed to approximately 310 PSI. The air is again cooled after leaving the second stage cylinder and passes through the second stage separator where moisture and oil are removed. The air then passes to the third stage cylinder where it is compressed to1200 PSI. The air then leaving the innercooler enters the third stage separator to remove moisture & oil. The air then passes to the final stage cylinder where it is compressed to the desired PSI. The air enters the aftercooler and is again cooled and enters the final separator which removes most remaining moisture and oil particles. Treated air then moves on to the back pressure regulator then to either a storage cylinder or to an SCBA or SCUBA cylinder. POWER SUPPLY: The unit is driven by a 15 HP, 380 VAC, 50 Hz electric, three phase motor. The unit should be connected to a fusible disconnect switch by a qualified electrician according to local codes. A magnetic starter with thermal overload for motor protection is provided. The control system is 24 VAC, fused with both a 6-1/4 amp fuse and a 3 amp fuse. FAILURE INDICATIONS: If an overheat condition or a low oil pressure condition occurs, the specific condition will be indicated by the appropriate panel light. The condition should be corrected prior to continued operation. If a fault occurs, the 'ON-OFF' switch must be turned 'OFF' and then back 'ON' to reset the system. A reset will occur if there is a power interruption. SURGE PROTECTION: This compressor is equipped with an electrical surge protection circuit. If an electrical surge is experienced, then the red LED Surge Protector indicator light will not be illuminated. The compressor will continue to operate if the light is out, but the surge protection circuit will be inoperable and the compressor is not protected from surges.

OPERATING INSTRUCTIONS 1. Move the 'OFF-ON' switch to the 'ON' position. The green 'POWER' light will

illuminate and the machine will automatically start. The 'LOW OIL PRESS' light will illuminate for a few seconds until the oil pressure builds to acceptable levels.

2. The unit will now operate until the selected pressure switch setting is reached or

until the selector switch is moved to the 'OFF' position. The automatic dump system will automatically drain condensate for 4-6 seconds every 15 minutes of operation and will drain the condensate on shutdown if the unit is allowed to run until the shutoff pressure is reached.

3. The unit may be manually restarted after the pressure at the back pressure

regulator has dropped 500-700 psi below the cutoff point. The machine will restart automatically if the "OFF-ON" switch is in the "ON" position and the air pressure drops 500-700 psi.

4. When done filling either individual SCBA's or storage cylinders, close the service

and cylinder valves. Bleed pressure from the service line slowly if disconnecting.

MAINTENANCE

AIR PURIFYING SYSTEM - P060 FILTER CARTRIDGES 65677 (quantity two) Purifier cartridge life depends greatly upon operating conditions of humidity and maintenance. However, the average life is approximately 60,000 cubic feet of treated air. The Carbon Monoxide monitor provides an indication of cartridge effectiveness. The elements of the indicator sense the presence of carbon monoxide. If carbon monoxide above 10 ppm is detected, the unit will be immediately shut down. The source must be determined before continued operation. Sources of carbon monoxide may be from ingested air due to the proximity of engine exhausts or of enclosed heaters or from the compressor itself if it has overheated for some reason. To change the cartridge, the unit must be shut down and the power switch placed in the 'OFF' position. The service valve should be closed and all residual pressure in the cartridge housing must be bled off using the bleed valve near the base of the purification chamber. Unscrew the top of the housings and extract the spent cartridges. Clean the interior of the housing with a soft, dry, lint-free cloth. Insert the replacement cartridges into the housing making sure that the rubber socket end of the cartridge is oriented downwards. Also be sure to remove the seals on both ends of the cartridge including snapping out the plastic plug on the top end of the cartridge. Replace the housing tops taking care to assure that they are fully threaded in place. It is not necessary to over-tighten the top of the housing as it has an o-ring seal. The Carbon Monoxide sensor element should be replaced every year, or as necessary. The bleed valve may now be closed and the unit placed back into service. CAUTION: Extreme care must be taken at all times to be sure that all pressure is

removed from the compressor system when performing maintenance. High pressure air is extremely dangerous and can cause severe injury or death if mishandled. Always stand clear of all devices after service until integrity has been established after pressure has been reestablished. Never stand over the top of the cartridge housings until system integrity has been verified.

LUBRICATION: Lubrication is effected through a splash method and by a forced pressure system. The compressor is shipped with a break-in oil in the crankcase. The crankcase holds 2.5 quarts and should only be serviced with synthetic lubricant after the first 75 hours of operation. Always check oil level before operating.

AUTOMATIC DRAIN SYSTEM: The drain system consists of three dump valves controlled by the second stage pressure, two solenoid valves and a timer. The timing sequence is controlled by the Logo! Relay. The condensate is collected in the innerstage and final separators and is automatically drained every 15 minutes. The discharged condensate should be collected in a catch vessel. A five gallon drum with a perforated top is suitable. PREVENTATIVE MAINTENANCE GUIDELINES The following items should be attended at the specified intervals: Daily before operating the air compressor

1. Check compressor oil level. 2. Check for obstructions to the air intake 3. Check for obstructions to the fan blades and belt

NACC_____________________________ 2

GENERAL DESCRIPTION

The North American Model NA18 compressor block is a reciprocating, single-acting, four-stage, air-cooled compressor designed to deliver up to 6,000 psi at 1340 rpm maximum, providing 16.5 scfm.

The Model NA18 has been designed for smooth and quiet operation, continuous duty, long life, energy effi -ciency, and convenient maintenance. The cylinders are arranged in an “X” pattern to permit a well-balanced drive train. The entire compressor is balanced as a unit to improve the smoothness of operation. Each piston is fi xed to the crankshaft to eliminate loose parts and noise. The crankcase and crankcase covers are made with heavy wall sections for noise damping and durability.

The continuous duty operation of the Model NA18 is achieved through a combination of design features. The air is cooled after each of the four compression stages through a corrosion resistant, air-cooled intercooler or after cooler. The block has fi nned aluminum cylinder heads, fi nned cylinders, and a fan-bladed fl ywheel. Oil injection is provided at critical high temperature locations utilizing a direct drive low-pressure oil pump. The NA18 also has large diameter connecting rod bearings for lower bearing loads.

The Model NA18 has two separators to collect the oil and water condensation which forms as the air is com-pressed and cooled.

All of the bearings are roller bearings for low energy consumption. The air and oil fi lters are easily change-able. The oil pump is replaceable and needs no adjustments. The front and rear crankcase covers can be separately removed without removing the crankshaft, thus simplifying drive train inspection.

AIR FLOW DESCRIPTION

Air enters into the fi rst stage cylinder through a micronic intake fi lter which separates particulate matter. The air is compressed in the fi rst stage to approximately 60 psi. The air is then cooled in the fi rst stage intercooler as it travels to the second stage.

Next, the air is compressed in the second stage cylinder to approximately 280 psi. The air is cooled via the second stage intercooler and then fl ows through the second stage separator where oil and water condensate is removed.

The air is then compressed in the third stage to approximately 1050 psi. The air is cooled through the third stage intercooler and then fl ows through the third stage separator where additional oil and water condensate are removed.

Finally, the air enters the fourth stage cylinder and is compressed to the fi nal operating pressure. As the air leaves the fourth stage, it passes through the fi nned after-cooler. The air is cooled through the after-cooler to within 15 degrees Fahrenheit above ambient temperature. The compressed air then proceeds through the purifi cation and control systems and into the storage vessels as assembled by the system manufacturer.

The intermediate stages of the compressor are protected by safety relief valves. The fi rst stage safety valve is located on the intake of the second stage cylinder head. The second stage safety valve is located on the top of the second stage separator, which is on the left opposite the pulley when viewing from the rear cover. The third stage safety valve is located on top of the third stage separator, on the right side of the compressor block. The fourth stage pressure, or operating pressure, is protected by the operating pressure safety valve, which is supplied and installed by the air system manufacturer.

NACC_____________________________ 3

LUBRICATION SYSTEM

General

The NA18 utilizes a low-pressure, direct-drive oil pump designed to assure adequate lubrication at criti-cal high temperature locations.

The oil pump is connected directly to the back of the crankshaft. The oil is picked up from the bottom of the crankcase and fl ows through a tube to an intake screen in the rear crankcase cover and into the oil pump. The oil is then pumped into an oil fi lter. If an oil pressure line is desired, remove the spare fi tting at the oil fi lter outlet for installation. The oil then fl ows from the oil fi lter into the fi nal stage cylinder. Most of the oil is directed into the cylinder, the cylinder sleeve, and around the upper piston. The excess oil fl ows into the crankcase where the crankshaft splashes it to the other stages.

The fi tting on the fourth stage cylinder reduces the outlet line to 1/8” and allows oil to go toward the front cover to lubricate the front bearings.

The oil ventilation tube connects the crankcase to the crankcase breather cylinder. This tube allows oil vapors from the crankcase to pass into the breather cylinder assembly, where upon shutdown, the col-lected oil will drain back into the crankcase while the pressure is vented to the atmosphere.

Oil Capacities

Crankcase fi lled to mid-level on dipstick Approx. 2.25 Quarts/2.12 Liters Oil fi lter Approx. 0.25 Quarts/0.24 Liters Total Capacity Approx. 2.5 Quarts/2.36 Liters

Recommended Oils

NACC recommends use of 30 weight synthetic oil, specifi cally designed for use in compressors, after the fi rst 75 hours of operation.

INSTALLATION

Initial Inspection

Before installing the compressor block you should check for damage to the unit which may have occurred during shipping. Look particularly for bent tubing or damage to the fan shroud, fan blades, and tubing hardware. After this initial inspection, rotate the fl ywheel by hand to see if it turns smoothly and produces whining noises from the valves.

Considerations for Mounting in Frame

The following should be considered when mounting the block in the frame:

• safe working conditions for maintenance;• protection for the block from the environment;• easy access to the lifting eye for future removal;• the pulleys of the motor and compressor must be in line and parallel;• the area in front of the fan is unobstructed so air can be pulled easily through the fan shroud;• the fan belt and blades must be completely guarded.

NACC_____________________________ 4

Bolting Compressor Block to Frame

When bolting the compressor down to the frame, you should make sure the surface is completely fl at so the base of the crankcase is not stressed when bolting. Bolt down the after-cooler clamp (Part # 808) with the mounting bolt, taking care to assure that the after-cooler does not rub against any other part. Refer to the drawing in the back of this manual for bolt locations.

Site Location

Any compressor system which incorporates the NA18 block must be:

• placed in a location with adequate ventalation;

• placed in a fairly clean area so dust and dirt will not gather on the cooling coils or clog the air intake fi lter so as to impair their operation; and

• placed where no toxic or unpleasant fumes are present. The air must be free of exhaust fumes, noxious gases, and cleaning agent fumes. The intake opening can be relocated. The manufac turer should be contacted for specifi c instructions.

Design of Process and Control Tubing

The process and control tubing and fi ttings used in any compressor system utilizing the NA18 block must be selected with the following considerations:

• Tubing should be rated for appropriate pressures and capacities. The fi nal pressure tubing should be rated to 6000 psi. Tubing rated at this pressure is recommended even if the system is to be operated at a lower pressure.

• Tubing must have suffi cient fl exibility and clamping for vibration.

• Before installing, all tubing should be deburred and blown out with shop compressed air to remove dirt or other materials.

• A fi nal stage relief valve should be installed and set by the system manufacturer in order to protect the tubing as well as all the high pressure equipment.

• The compressor must be equipped with a pressure switch set to shut the compressor off when the fi nal pressure is reached.

• An oil pressure switch must be installed to shut down the compressor if the oil pressure drops below 40 psi.

Tubing Connecting Points

The connection points for the installation of tubing are located as follows:

• The intake pressure location is a plugged 1/8” NPT tap located just above the intake fi lter on the fi rst stage cylinder head.

• The fi rst stage pressure location, also an 1/8” NPT tap, is located over the outlet line on the fi rst stage cylinder head.

• The second stage pressure location (1/8” NPT tap) is on the second stage separator.

NACC_____________________________ 5

• The third stage pressure location (1/8” NPT tap) is on the third stage separator.

• The oil pressure location is on the outlet of the oil fi lter. This connection utilizes 1/4” tube and Parker A-lock fi ttings.

• The after-cooler outlet is a 1/4” stainless steel tube using a Parker nut and ferrule. Parker unions should be used to connect another 1/4” tube to this fi tting. The union comes with two caps and ferrule assemblies, one cap and ferrule assembly is already on the tubing so you can use the spare cap and ferrule assembly for the oil pressure line. If another type of fi tting is preferred, cut the end of the after-cooler off, deburr the tube, vacuum out the debris, and put the new fi tting on the end.

Motor Sheave Selection

To order a sheave, the following information is required:

• The pulley on the NA18 block is a 12.4B. The “B” belt has a pitch diameter of 12.4”.

• The RPM depends on the capacity needed. See chart below.

1200 RPM 16.0 CFM, max. pressure 6000 psi 1340 RPM 17.8 CFM, max. pressure 6000 psi

Drain Line

To locate the drain line, use the 3/8” NPT tap on the right side of the oil pump feed line to run to a desir-able location.

Belt Tension

To obtain the correct belt tension, roughly measure the distance between shaft centers, and divide the distance by 64. This will determine the desired belt defl ection distance. Use a V-belt tension tester and a straight edge across the top of the belt to measure the force required to defl ect the belt from its relaxed position to the belt defl ection distance. Adjust the belt until this force is 15-20 lbs. As a general indica-tion of correct tension, the belt should twist about 90 degrees (one quarter turn) with moderate effort and should defl ect up and down about ½” to 3/4”.

Initial Start Up Procedure

Before initial operation of the NA18 compressor block, perform the following procedures:

• Fill the block with oil to a point between the “Full” and “Add” lines on the oil dipstick. Be sure to use the recommended type of oil. See “Oil Specifi cations”

• Check for obstructions to the smooth operation of the belt or blades; inspect both visually and by manually rotating the fl ywheel.

• Check for any obstructions to the air intake.

NACC_____________________________ 6

• Activate the compressor momentarily to check for correct rotation, loose parts, and fan blade or belt obstructions. The rotation should be counter-clockwise when looking at the fl ywheel.

• Activate the compressor for 60 to 120 seconds to purge the air lines and check for oil pressure.

• Activate the compressor to check the fi ttings for tightness and absence of leakage. Each fi tting should be checked for leaks with soap and water or commercial leak-testing solution. If leaks exist, all pressure should be bled off of the entire system, the power disconnected, and all leaks corrected. In the event of such repairs please review the safety warnings at page 2 of this manual.

• Activate the compressor and allow it to operate at approximately 1000 psi for about 30 minutes. The oil pressure should increase toapproximately 50 psi with in a few seconds. The oil pump will make a small clicking noise until the pressure builds up. All air pressures should be reached a few seconds after the separator drain valves are closed. See “Correct Operating Pressures.” If the valves are working properly, each of the inlet lines should be warm and the outlet lines should be hot. The outlet lines may be hot enough to cause burns so use caution in checking the temperature of the lines.

Break-In Procedure

After 75 hours of operation, the oil and oil fi lter should be changed. See “Changing the Oil.” The oil should be changed to synthetic-type oil at this time.

After 175 hours of operation, the oil and oil fi lter should be changed. Thereafter, the recommended routine maintenance procedures should be followed. See “Maintenance.”

OPERATION

Before starting the compressor, it should be determined that the unit has been properly installed, that there are no obstructions to the fan blades or drive belt, or obstructions or dirt on or near the air intake. The oil level should also be checked. If additional oil is needed, add to the proper point on the oil dip-stick. Always use the oil recommended by the manufacturer.

In manual drain systems, after opening the separator drain valves, activate the power drive, make sure the oil pressure rises to 60 psi within a few seconds, then close the drain valves. The drain valves should be opened every 30 minutes while the compressor is running; in high humidity environments, the separators should be drained every 15 minutes. The compressor will run until the cut-off pressure is reached. At this point, the drain valves should be opened.

Note: Operation of the compressor block without pressure (unloaded) will cause a greater amount of oil vapors to be released into the outlet air.

MAINTENANCE

Basic Maintenance Requirements

Before operating the compressor each day:• Check the oil level.• Check for obstructions to the air intake.• Check for obstructions to the fan blades and belt.

NACC_____________________________ 7

After every 100 hours of operation:• Change the oil if using mineral oil.• Check and clean the air intake fi lter element.

After every 200 hours of operation:• Check all fi ttings for leakage.• Change the oil and oil fi lter.• Check the drive belt.• Check the tightness of all valves.

After every 1000 hours of operation: • Replace the air intake fi lter element.• Replace the drive belt.• Inspect and clean all valves.

Note: All of the items above must be performed at least once a year regardless of number of operating hours.

After every 2000 hours, all valves should be checked for proper operation or replaced.

On an annual basis, all safety relief valves should be checked for correct pressures and the exteior of the block thoroughly washed.

It is expected that the piston rings, cylinders, bearings, and seals will need to be replaced after 2,000 to 5,000 hours of operation. See “Troubleshooting” for procedures to determine when replacement is necessary. Replacement of these components requires special tools and procedures not covered in this general maintenance manual.

Maintenance Log

It is recommended that all items of maintenance performed on the compressor block be consistently recorded on the log provided in the back of the manual.

Checking the Oil

Before checking the oil, wait fi ve minutes after compressor shutdown. Clean the outside of the dipstick tube around the dipstick, turn the handle of the dipstick counter-clockwise to loosen, remove the dipstick, and wipe off the oil with a lint-free cloth. Next, insert the dipstick in the tube without tightening and avoiding contact with the inside of the tube. Then, remove the dipstick and read the oil level. Add oil until the level is at the proper level on the dipstick. Avoid overfi lling.

Changing the Oil and Oil Filter

Before changing the oil, the compressor should be run with moderate fi nal pressure for 30 minutes to warm up the oil. The following procedure should be followed:

• Clean the outside of the dipstick tube around the dipstick, remove the dipstick and clean with a lint-free rag. If the surrounding environment is dusty or dirty, place a lint-free rag over the open -ing.

• Remove the plug on the drain line, if equipped, and completely drain the oil.

NACC_____________________________ 8

• Remove the magnetic drain plug on the block and clean all deposits from the magnet.

• If the maintenance schedule calls for the oil fi lter to also be changed, the area around the fi lter should be cleaned, the fi lter unscrewed, and the surface of the oil fi lter bracket cleaned. The new oil fi lter should then be fi lled with new oil, the rubber gasket lubricated with oil, and the new fi lter installed. The oil fi lter should be tightened 3/4 to 1 turn after gasket contact. Do not over tighten.

• When the oil is completely drained, reinstall all the drain plugs, and tighten the magnetic drain plug with the plastic washer to 60 in-lbs. Do not over tighten.

• Refi ll the crankcase with 2.25 quarts of new oil, then activate the compressor and inspect the block for leaks. Oil pressure should rise to approximately 50 psi within a few seconds after start up.

• After 5 minutes of operation, check the oil level with a lint-free cloth. Fill the crankcase with new oil until the level is at the proper level. Do not overfi ll. Then, tighten the oil dipstick by turning the handle clockwise.

Cleaning the Oil Pump Intake Screen

In the rear cover of the NA18 is the intake screen which prevents entry of particles into the oil pump. This screen needs to be periodically cleaned to assure proper oil fl ow. When the screen is obstructed, the oil pump will make a clicking noise and the oil pressure will drop slowly. The procedure for changing the oil pump intake screen is as follows:

• Shut the compressor off and disconnect the power. Always read the warning statements before working on the compressor.

• After laying some rags under the oil pump, loosen the four 1/4” Allen bolts securing the oil pump.

• If the oil pump does not pull off easily, tap lightly with a rubber mallet to break the oil pump gasket free. Do not turn the oil pump shaft; this will ensure that it will be properly aligned when the pump is reinstalled.

• If the gasket is still on the rear cover, gently remove it. Then remove the oil pump intake screen on the left side of the rear cover, and clean or blow off any particles on the screen. If the rubber around the screen is hard or deformed, use a new screen.

• Reinstall the oil pump intake screen with the tip of the cone facing inside the rear cover.

• Reinstall the oil pump, gasket and bolts in the reverse order that they were removed. Use a new gasket if the old one is torn or brittle. Torque the bolts in a criss-cross pattern to 195 inch pounds.

• Activate the compressor, listen for the clicking noise in the oil pump. If the noise does not stop, see “Troubleshooting.”

• Inspect for leaks.

NACC_____________________________ 9

Checking the Drive Belt

The belt should be checked for age and deterioration by visual inspection. If the belt is brittle and has started cracking, it should be replaced.

The tension of the drive belt should be regularly tested. If a tension tester is available, the tension should be determined to be 15 to 20 lbs. See “Installation.” If a tension tester is not available, a quick test can be performed by hand. The belt should defl ect about ½” and should not be able to be twisted much more than one quarter turn.

Changing Intake and Outlet Valves

Read the warning statements before beginning to change the valves. Be sure to fi rst disconnect the power, allow the compressor to cool down, and bleed off the system air pressure.

Inspection of the Valves - Each part should be checked for wear and/or damage. The O-rings should be checked for tears or brittleness. The copper gaskets and all the other sealing surfaces should be checked for scratches. The sealing surfaces should exhibit a shiny area of contact around the entire surface. If the contact area is not present, this may indicate improper torque on the valve. See “Troubleshooting.”

Valves with over 2000 hours operating hours should be checked to avoid fatigue failure which can cause damage to the head, piston, or cylinder before trouble is detected.

Servicing the First Stage Valves

• Disconnect the tubing and remove the valve cap nuts and washers.

• Gently separate the valve from the head, avoiding any damage to the copper gaskets.

• Clean, inspect, and replace the valves, if necessary.

• When assembling the valve with the head make sure the old gaskets are usable and that each valve is in the proper port in the cylinder head.

• Bolt the whole assembly together with the valve cap washers and nuts and torque in a criss-cross pattern to 195 inch pounds.

Second and Third Stage Head Removal - Disconnect the tubing, remove the cylinder head bolts with a 1/4” Allen wrench, and remove the head. Note: If only the outlet valve on the second or third stage needs to be replaced or cleaned, the cylinder head does not need to be removed.

Second and Third Stage Inlet Valve - Remove the inlet valve (Part #203) with a special valve tool. Inspect the valve and replace if worn or damaged. Also, check the cylinder head gasket and replace it if necessary.

Upon reassembly, tighten the valve body to 80 foot pounds. Make a punch indentation near the threads to help hold the valve in place.

NACC_____________________________ 10

Second and Third Stage Outlet Valve - Remove the valve body. Inspect the valves and replace any valve that is worn or damaged.

Note: Make sure the valve seat is not bent or scratched so as to cause the valve not to seat properly.

Bolt the cylinder head to the cylinder with the Allen bolts. Tighten the bolts in a criss-cross pattern to the specifi ed torque.

Final Stage Inlet Valve - Disconnect the tubing, remove the cylinder head bolts and remove the cylinder head. Then remove the inlet valve with the special valve tool and inspect or replace the valve as neces-sary. The inlet valve should be installed with the special valve tool. Press down fi rmly on top of the tool while holding the torque wrench level with the valve and tighten to the specifi ed torque. Be careful to avoid letting the valve tool slip out of the valve, causing damage to the parts.

Final Stage Outlet Valve - Remove the outlet valve from the cylinder head. Be careful not to damage the surface of the top of the head or the O-Ring. Clean and inspect the valve and O-Ring and replace if necessary.

When reinstalling, fi rst put the O-ring inside the groove on the cylinder head and then push the valve through it into the head. This will seat the O-Ring inside the groove.

If the stud (Part #516) is still in the fourth stage cylinder head cap (Part #120), then remove it before reassembly. The cylinder head assembly bolts should be tightened in a criss-cross pattern to the specifi ed torque. Next, install the stud (Part #516) and torque to 125 inch pounds. Then, install the copper washer (Part #539) and the acorn nut (Part #517) and torque the nut to 150 inch pounds.

General Instructions After Valve Cleaning or Changing - After the fi ttings are reconnected, the compres-sor should be run and a determination made that the interstage pressures are close to normal. Pressures will not completely return to normal until the valves seat. If a valve in any stage is defective or incorrectly installed, the pressure in the prior stage will be too high and will probably cause discharge from the relief valve. The compressor should be shut off immediately if a relief valve discharges or if any interstage pressure is too high. If this occurs, check the valves on the next higher stage.

After replacement of valves, the compressor should be checked for air and oil leaks. The charging rate should also be checked to assure return to original capacity.

After cleaning or replacement of valves, the compressor should be run for 60 minutes under medium load to let the valve parts settle. After this period of operation, the unit should be allowed to cool to ambient temperatures and the outlet valve studs and acorn nuts retightened.

All procedures in cleaning or replacement of valves should be recorded in the maintenance log.

Checking the Tightness of Valves - The torque chart should be used when checking the torque of the inlet and outlet valves. In order to check the torque of the valves, certain tools are needed: 5/32” (or 4mm) and 1/4” hex drivers; ½” (or 13 mm) and 1 1/4” sockets; torque wrench with range from 125 to 225 inch pounds and 10 to 80 foot pounds; and inlet valve tools (available upon request from NACC).

Air Intake Filter - The air intake fi lter should be checked and, if necessary, replaced at regular intervals according to the recommended maintenance schedule.

NACC_____________________________ 11

The air intake fi lter element should be removed and replaced if it has a covering of dust, grit, or oil. If these are not present, low-pressure compressed air should be blown through the element backwards to dislodge and eliminate any particles.

Checking Safety Relief Valves - The safety relief valves must be checked annually to assure their proper operation. If a relief valve is not properly maintained, corrosion may cause it to stick which could cause damage to the compressor block.

The relief valves are set by the manufacturer. If a relief valve is not operating within these tolerances noted of the data plate, it should be replaced.

Note: The air system package manufacturer’s recommendations should be consulted for testing of the fi anl stage relief valve.

Washing the Compressor Block - The exterior of the compressor block should be washed periodically to assure that the various components continue to effi ciently dissipate heat.

When washing the unit, make sure all openings on the block are plugged. The air intake fi lter housing should be removed and a pipe plug installed with Tefl on tape. Remove the element from the fi lter hous-ing and wash the housing with soapy water.

Use a non-fl ammable, rust-resistant, degreasing solution to clean the block. Test the solution in a non-conspicuous location to see if it reacts with the paint. Soap and water is not recommended because it can cause rust if there is a chip or scratch in the paint. Do not use high pressure washers as fl uid may get past the seals and into the oil. Chemicals in the cleaning solution could cause the oil to loose its lubricating properties and eventually damage the block. If drying the compressor block with compressed air, do not apply the air fl ow any closer than two feet from the surface of the block to avoid blowing solution past the seals and into the lubricating oil.

Storing the Compressor Block - If the compressor block will not be used for more than six months, it should be stored using the following procedures:

• Make sure the fi lters are in place to protect the system from additional oil vapors which pass through the system during the storage procedure.

• Run the compressor with the separator drain valves open and without fi nal stage pressure for approximately 15 minutes. This will purge the separators and allow the fi nal stage ring assembly to be thoroughly oiled.

• Shut off the power drive and allow the compressor to cool to near ambient temperature. This will enhance the adherence of the lubrication injected into the air stream in the following steps.

• Remove both parts of the air intake fi lter housing from the fi rst stage cylinder head.

• Activate the compressor and inject approximately one half cubic inch (about 4-5 shots from a clean oil can) of oil into the fi rst stage cylinder head air intake port.

• Close the separator drain valves and run the compressor for approximately 40 seconds to allow the oil to distribute to the other stages, then open the drain valves and run the compressor for an additional 20 seconds or until no condensate comes out of the line.

• Plug the inlet port on the fi rst stage cylinder head with a standard pipe plug (1” NPT) and tefl on tape.

NACC_____________________________ 12

• Close the separator drain valves and the outlet valve on the compressor. If the compressor does not have an outlet valve, then plug the outlet line so moisture cannot enter the tubing.

• Top the block off with oil and tighten the oil dipstick fi rmly.

• If any air or oil lines are disconnected from the block, plug the lines and the openings on the block.

• Place a “Date of Storage” tag on the block indicating when the compressor was put in storage and referencing the procedures to follow when the block is reactivated.

• Repeat this procedure every six months during the storage period. The oil should be changed every two years while in storage, and a record of the changes made on the storage tag.

• The recommendations of the compressor system manufacturer should be followed for preserv ing the motor, engine, or other system hardware.

Reactivation After Storage - When the compressor block is reactivated after a storage period, the follow-ing procedures should be used:

• Carefully clean the outside of the block of all dust and grime before removing any plugs or caps. The areas around the plugs and caps should be given special attention during cleaning.

• Remove plugs from the openings and re-connect the air and oil lines.

• Remove the plug from the air intake fi lter opening on the fi rst stage cylinder head, then reinstall the air intake fi lter. The fi lter element should be examined and replaced if necessary.

• Change the oil if more than a year has elapsed since the last oil change. Otherwise, check the oil level and top-off if necessary.

• Open the separator drain valves, activate the power drive, and allow the compressor to run with out pressure for approximately 60 seconds. Then gradually allow the compressor to build pres sure while checking for correct inter-stage air pressures and oil pressure.

• If any problems are experienced, see “Troubleshooting.”

• Filters in the compressor fi ltration system should be changed according to the instructions of the system manufacturer.

TROUBLESHOOTING

The Model NA18 compressor block is designed and manufactured to provide many years of reliable service if properly installed, operated, and maintained. It is possible, however, that operating problems might be experienced. If so, it is suggested that the indicated corrective measures be taken.

No Oil Pressure - If there is no indication of oil pressure upon activation of the compressor, the possible causes are:

• Incorrect fl ywheel rotation.• Clogged oil line, fi tting, or intake screen.• Faulty gauge or switch.• Oil pump not primming. New pumps self-prime but older models may need to be re-primed after removing from rear cover.• Broken shaft on oil pump or broken tab on crankshaft.

NACC_____________________________ 13

Recommended Action:

• Check the rotation of the fl ywheel to be sure it is turning counterclockwise when looking at the fl ywheel.• Disconnect fi tting at oil pressure gauge and visually check for proper fl ow. Check for pressure by lightly plugging and releasing the fl ow with your thumb. The oil should build up pressure and spray out when released. Then trace back to where the oil stops fl owing. If the oil pump makes a clicking noise, start with the oil intake screen and then proceed to the oil pump intake lines and fi ttings. • Check the oil pressure gauge or switch with another source of pressure or replace with a new part.• Remove the oil outlet tube and inject oil into the fi tting while turning the fl ywheel backwards.

Note: Disconnect power supply and read the other warning statements at the front of this manual before turning the sheave by hand.

• Remove the oil pump from the rear cover and inspect the shaft and the tab.

Low or Dropping Oil Pressure - Dropping oil pressure occurs when the oil pressure starts out normally and then gradually decreases over a few minutes. Possible causes of this condition are:

• Low oil level.• Blockage in the oil intake system (causing the oil pump to make a clicking noise).• Oil leak.• Blockage in oil discharge system.• Malfunction in oil pressure gauge.• Malfunction in oil fi lter.• Malfunction in oil pump.

Recommended Action:

• Add oil to the proper point on oil dipstick.• If the oil pump makes a clicking noise, examine the oil pump intake screen. See “Maintnance.”• Check for oil leaks.• Disconnect the fi tting at the oil pressure gauge and check for proper fl ow. If there is no fl ow, check all the oil tubing and fi ttings. If there is proper fl ow, check or replace the oil pressure gauge.• Replace oil fi lter.• Replace oil pump.

Fluctuating Oil Pressure - If the oil pressure continuously fl uxuates in a range of 15 psi, or if output is down and the gauge shows pressure for more than eight seconds after deactivation of power, the possible causes are:

• Dirty oil.• Clogged oil lines, fi ttings, or oil fi lter.• Malfunction of oil pump.• Loose fi nal stage ring stack cap screw.• Worn fi nal stage rings.

NACC_____________________________ 14

Recommended Action:

• Change the oil.• Check all oil lines, fi ttings, intake screen, and replace the oil fi lter.• Replace the oil pump.• Remove the fi nal stage cylinder head and tighten the cap screw.• If the fi nal stage rings are not working properly, this will also result in low output. See “Low Output.”

Clicking Oil Pump - If the oil pump makes a continuous clicking sound while the compressor is running, particularly if this condition is accompanied by low oil pressure, the possible causes are:

• Low oil level• Clogged intake screen• Foamy oil• Clogged intake lines or fi ttings.

Recommended Action:

• Add oil to the proper point on dipstick.• Clean oil intake screen. See “Maintenance.” While the oil pump is off, check to see if the oil looks foamy.• Check for blockage in the intake line and proper installation of all fi ttings in the lubrication system. Also, check inside the crankcase near the crankcase oil intake fi tting.

Foamy Oil - If the oil looks foamy or has many bubbles in it, the possible causes are:

• Water in the oil.• Improper oil type has been used.• Malfunction of the fourth stage rings. Recommended Action:

• Change the oil and determine how the water became mixed in with the oil.• Check the oil used against the list of oils recommended by the manufacturer. Replace oil if necessary.• If the fourth stage rings are not working properly, this will also result in low output. See “Low Output.”

Low Air Pressure on First Stage - If the fi rst stage is not obtaining the pressure specifi ed by the manu-facturer, the possible causes are:

• First stage valves are not functioning properly.• Air intake fi lter is blocked or clogged. • Leakage in fi rst stage relief valve, head gaskets, or piping to second stage.• Piping to air pressure gauge is obstructed or leaking.• Air pressure gauge is not functioning properly.• Worn or damaged fi rst stage rings.

NACC_____________________________ 15

Recommended Action:

• Clean and check valves. See “Maintenance.”• Check air fi lter element. See “Maintenance.” • Check for air leaks. See “Maintenance.” • Check for air fl ow to air pressure gauge. See “Maintenance.” • Check air pressure gauge and replace if necessary.• If output is also down, replace the rings.

Low Air Pressure on Second, Third, and Final Stages - If the second, third, or fi nal stages are not provid-ing the pressure specifi ed by the manufacturer, the possible causes are:

• Intake or outlet valve in preceding stage not functioning correctly.• Leak in the relief valve or head gaskets or in piping to next stage.• Separator drains are open or leaking.• Piping to air pressure gauge is plugged or leaking.• Air pressure gauge is not operating correctly.• Worn or damaged rings on effected stage or a preceding stage.

Recommended Action:

• Clean and check valves. See “Maintenance.”• Check for air leaks. See “Maintenance.” • Close manual drains or check automatic dump system.• Check for air fl ow to air pressure gauge. See “Maintenance.” • Check air pressure gauge and replace if necessary.• If output is also down, replace the rings. Refer to rebuild manual or authorized service location.

High Air Pressure on First, Second, or Third Stage - If the pressure on the fi rst, second, or stage exceeds the limits specifi ed by the manufacturer, the cause is a malfunction of the inlet or outlet valve in the next higher stage. This condition should be remedied by cleaning and checking the valves. See “Main-tenance.”

Safety Relief Valves Activation - If a safety relief valve activates, this is due either to a malfunction of the valve or to an excessive interstage pressure caused by malfunctioning valves in the next higher stage. If this occurs, you should test and, if necessary, replace the safety valve, and clean and check the particular intake and outlet valves. See “Maintenance.”

Low Output - If the compressor is not producing the specifi ed output of compressed air, the possible causes are:

• Leakage in the piping, relief valves, or head gaskets.• Malfunctioning of the intake or outlet valves.• The separator drains are open or leaking.• Power drive speed is set too low or drive belt is slipping.• Air intake fi lter is obstructed.• Piston rings are worn or damaged.

NACC_____________________________ 16

Recommended Action:

• Shut off the compressor with pressure on all stages and check for leaks.• Check for any high interstage pressure. If detected, clean and check the valves in the next higher stage. See “Maintenance.”• Close manual drains or check automatic dump system.• Check belt tension. See “Maintenance.” Check sheave ratios for determining block RPM from motor RPM. • Replace air intake fi lter element and check for obstructions to intake. Make sure intake piping is not undersized..• Replace piston rings.

Compressor Running Hot - If the temperatures of the compressor block during operation exceed the temperatures specifi ed by the manufacturer, the possible causes are:

• Low oil level.• Improper oil type or old oil is utilized.• Restricted circulation of cooling air.• Compressor block is dirty.• Interstage pressure is too high.• Ambient temperature conditions are too high.

Recommended Action:

• Add oil to the proper point on the dipstick.• Change the oil. See “Maintenance.” Be sure to use oil type recommended by manufacturer.• Check for obstructions to the cooling fan. See “Installation” for considerations in locating the compressor unit.• Wash the compressor block, especially the after-coolers, following the procedure described in “Maintenance.”• Check for any high interstage pressure. If detected, clean and check the valves in the next higher stage. See “Maintenance.”• Consult the specifi cations for maximum ambient temperature. If necessary, only operate the compressor in the morning or evening.

Noisy Compressor Operation - Possible causes of excessive noise created during operation of the compressor are:

• Low oil level.• Low oil pressure.• Block is not securely mounted in frame.• Flywheel is out of balance.• Internal or external parts are loose, worn, or damaged.

Recommended Action:

• Add oil to the proper point on the dipstick.• Check the operation of the oil pressure gage and cut-off switch. Check for blockages in the oil lines to the forth stage cylinder and front cover.• Check and secure all mounting bolts.• Check to determine that the balancing weights on the fl ywheel are in the same position as the punch-mark in the crankshaft. Check for loose or missing bolts on fl ywheel.• Check external brackets and bolts for tightness. If integral parts are suspected to be malfunction ing, refer to the rebuilding manual.

NACC_____________________________ 17

Rust Forming on Cylinders and Valves - If rust is forming on the cylinders or valves, the compressor is not being operated correctly. See “Operation” for correct operating procedures.

Excessive Oil Consumption - If excessive oil is being used during operation, the possible causes are:

• Improper type of oil being used.• Oil leak in piping, gaskets, or front seal.• Block is being operated with low air pressure.• Worn or damaged rings.

Recommended Action:

• Use recommended oil types. See “Maintenance.”• Check for oil leaks. See “Maintenance.”• If compressor unit is to be operated at low air pressure on a regular basis, consult manufacturer for guidance in adjusting oil pressure for particular application.• If output is also down, replace the rings. Refer to the rebuild manual or authorized service location.

Worn or Damaged Final Stage Rings - If the fourth stage rings are determined to be worn or damaged, refer to the rebuild manual or authorized service location. The possible causes for pre-mature ring failure are:

• Oil not changed regularly• Low oil level• Low oil pressure• Foamy oil• Overheating

Recommended Action:

• Change the oil as recommended in maintenance schedule.• Make sure the oil level is always between the marks on the dipstick. Always check the oil level before activating the compressor.• Make sure the oil pressure switch is operating correctly. An oil pressure gauge is recommended. See “Low or Dropping Oil Pressure.”• See “Foamy Oil.”• See “Compressor Running Hot.”

OPERATION & MAINTENANCE The visual indicator allows an operator to see two indicating elements in the high pressure line. The cards are seen through a high strength plastic window. The moisture card progressively changes color from blue to pink as moisture increases. A carbon monoxide indicator changes color from tan to gray or black as carbon monoxide increases. When either element changes color, it is time to change the purification filter cartridge(s). The carbon monoxide indicator responds slowly over a period of several minutes so only provides an adequate warning for slowly changing conditions. Consequently it should be considered only a back-up to faster responding electronic instruments if carbon monoxide build ups can occur. The indicator elements are easily removed and changed from the front of the unit. No access to the back of the unit or disconnecting of lines is required. No tools are required. NOTE: All pressure must be released before opening. To install the element, unscrew the cap (2). The elements (7 & 8) are then placed in the housing with the active side facing the window (3) to permit visual observation. When reinstalling the cap, insure the spring is in place to hold the element against the window. Tighten hand tight only. Use No Tools. SPECIFICATIONS • Maximum pressure rating ------------------------- 6000 PSI • Inlet & outlet ports --------------------------1/4" female NPT • Size ---------------------1.5"dia.x 2.25" w/0.5" dia view port • Humidity indicator ----- turns pink when humidity is 50% • Carbon monoxide indicator --------- turns gray when CO

Flow should be through the indicator. Do not install the indicator in a tee to one side of the main flow. This would increase the time it takes for the indicator to respond. The indicator is sufficiently light so it can be supported by the piping connections. It can be installed with the window facing any direction. The indicator is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.

OPERATION AND MAINTENANCE MODEL 504 & 504H RELIEF VALVE

The model 504 is an economical, small, high-pressure relief valve having excellent set pressurecontrol over a large pressure range to 6000 PSI.(6500 PSI for the 504H model.) It stays bubble tightto within a few PSI of set pressure and reseatsbubble tight even after many vent cycles. Safetywire holes are provided for optional locking of setpressure adjustment.

SPECIFICATIONS

• Set pressure ------------- adj. 300 to 6000 PSI(6500 PSI for 504H)

• Leakage ------------------- bubble tight• Max. flow (air) ------------ 100 SCFM at 3000 PSI

50 SCFM at 1500 PSI• Equivalent orifice ------- .078 inch dia.• Fluids ----------------------- gas or liquid• Inlet ------------------------- 1/4" male NPT• Outlet ----------------------- side vent• Size ------------------------- 7/8" hex by 2.1" long• Temperatures ----------- -40F to 160F• Materials ------------------ bronze,

anodized aluminum, &Viton

INSTALLATION

Use pipe thread sealant Teflon tape on inlet andoutlet threads. Avoid over torquing pipe thread.Normal torque applied with a 6 or 8 inch long wrenchis ample. Use ample Teflon tape - 3 or 4 turns, not 1or 2 turns. It is important to maintain piping internalsfree of particulates such as metal chips, dirt, weldslag, etc. If present these will tend to lodge in therelief valve when it opens causing damage to theseat and leakage. Since it is difficult to keep pipingcompletely clean during assembly it is advisable toblow high velocity air through the system and out therelief valve port just prior to installing it. This normallycleans the system of particulates. A high-pressureair tank can provide a strong flow for this cleaningoperation. Suitable ear and eye protection shouldbe used when flowing high-pressure air. It is NOTadvisable to install any type of filter before the reliefvalve. A filter could become clogged disabling thesafety function of the relief.

The relief can be either set prior to installing inthe system or after. Set the relief above setpressure using the adjusting screw (item 6 in thedrawing). Bring system pressure up to desiredrelief valve pressure then back off the adjustingscrew until the relief valve vents. Use the lockingnut (item 7) to lock the position of the setscrew.Cycle pressure once or twice to insure the reliefopens at the desired pressure. Safety wire holesare provided in the body and adjusting screw.The regulator is NOT shipped oxygen clean andshould NOT be used for oxygen service asprovided. Consult the factory for details onoxygen service.

MAINTENANCE & REPAIR

Routine maintenance is generally not required.As mentioned above, the relief is sensitive tosolid particles flowing through it. As with anyrelief valve, these particulates tend to lodge onthe sealing surfaces or damage the sealingsurfaces as they pass through. The result isleakage after the valve reseats.In the event of leakage, the valve can be repairedas follows. (Refer to the drawing on the oppositeside of this sheet.) Remove adjusting screw 6,spring 8, spring guide 5, and poppet 4. Inspectthe sealing edge of the poppet 4 for scratchesand seal surface 9 for imbedded particles. A 5Xor 10X magnifier is helpful for this inspection. Inmost cases the problem will be imbeddedparticles in the seal. These can be removed witha Q-tip, or tooth pick. If this does not correct theproblem the seal 9 and possibly the poppet 4 willneed to be replaced. To replace the seal 9,remove poppet guide 3 using a largescrewdriver. If a new seal is not available the oldseal can be turned over and reinstalled. Thisexposes a fresh sealing surface. The seal is a 90durometer (extra hard) size 2-006 O ring. Theseare readily available. When installing the sealinsure washer 6 is installed under the seal asshown. Insure the seal and washer stay in placeuntil the guide 4 is installed. Torque guide 4about as tight as possible while holding the reliefvalve body - i.e. without using a wrench on thebody.IN ALL CASES THE UNIT CAN BE RETURNEDTO THE FACTORY OR DEALER FOR REPAIRUNDER WARRANTY OR AT A NOMINALCHARGE. Maintenance or repairs can be doneby qualified personnel in a clean environment byfollowing the drawings and parts lists herein.

OPERATION AND MAINTENANCE MODEL 211 BACK PRESSURE REGULATOR

GENERAL

Also known as a priority valve, the model 211 is a fullybalanced, economical regulator. It serves a wide varietyof uses, however it's main use is on small compressors.The regulator will improve moisture separator efficiencyand filter life as much as 450%. This is done bymaintaining pressure in the separator and filter at 1800PSI or more when tank pressure is lower. It has twooutlet ports permitting attachment of a filling yoke andgauge directly to the regulator. This eliminates costlyfittings.

SPECIFICATIONS

• Maximum rated pressure - 6000 PSI (40 MPa)• Set pressure - 1800 PSI (adjustable 300 to 5000)• Materials - Anodized aluminum body, brass,

stainless steel, Viton seals• Flow capacity - 2 to 50 SCFM• Leakage - Zero external; 0.05 SCFM internal• Ports - 1/4" female pipe thread (NPT)• Size - 3 1/2" x 1 1/2" x 1"

INSTALLATION

Use a suitable pipe thread sealant such as teflon tapeon the inlet and outlet ports. Plug the second outletport if not used. Connect the inlet to the source gassuch as a compressor. If the regulator is installed in apiping line insure it is adequately supported or adjacentpiping is supported so any possible force on theregulator or piping will not damage or break the piping.The regulator is NOT shipped oxygen clean andshould NOT be used for oxygen service as provided.Consult the factory for details on oxygen service.

OPERATION

In operation the back pressure regulator will maintain itsset pressure upstream and allow just enough gas flowto hold this pressure. The set pressure can beadjusted by loosening the 7/8" hex nut and turning theadjusting screw with a 5/16" Allen wrench. Setpressure is pressure at the inlet port when gas isflowing through the regulator. The gauge connectedto the outlet gauge port does not read set pressure. Itreads pressure of the tank being filled down stream ofthe regulator.

MAINTANENCE & REPAIR

Routine maintenance is generally not required. Underextended or severe operation it is helpful to relubricatethe poppet seal item 8. (see drawing on opposite side).To disassemble, loosen nut 6 and remove adjustingscrew 5 along with spring 7 and guide 4. Remove seat10 using a 1/8" Allen wrench. Push out poppet 3, seal8, and 13. Avoid using sharp instruments to removeseal. A paper clip bent sharply and with rounded tipworks well to fish out seal 8 from the body 1. Slip seal 8then back up 13 on poppet 3 and position about 1/8"from poppet shoulder as shown on the drawing. Fullypack area between the shoulder and seal with grease.Also pack about a 1/8" area on other side of seal. UseCristo-Lube MCG 121 grease or equivalent, per MIL-G- 27617 types 2 & 3. Drop poppet and seal back into thebody. Lightly grease the threads and seal 10 on seat 2and screw tightly into body. Reinstall spring, springguide and adjusting screw as shown. Reset regulatorby applying pressure to the inlet and adjusting setscrew 5 so flow starts at desired set pressure.Excessive leakage can occur internally between theinlet and outlets resulting in a drop in set pressure.This is generally due to dirt or other particulatesdamaging the seat 2. Leakage can sometimes bereduced by lightly tapping ball 9 against seat 2 thusforming a new seal surface. This can be done byinserting a 1/4" rod through the adjusting screw holeand tapping with a hammer. If this does not work, theseat 2 must be replaced.A repair kit consisting of seat, poppet, and seals (partnumber 211-12) is available.IN ALL CASES THE UNIT CAN BE RETURNED TOTHE FACTORY FOR REPAIR.
