SAFETY

1.1 GENERAL

Sullair designs and manufactures all of its productsso they can be operated safely. However, theresponsibility for safe operation rests with those whouse and maintain these products. The followingsafety precautions are offered as a guide which, ifconscientiously followed, will minimize the possibilityof accidents throughout the useful life of thisequipment. Read the CIMA Safety Manual prior tocompressor operation and towing, if applicablein your area.

The air compressor should be operated only by thosewho have been trained and delegated to do so, andwho have read and understood this Operator’sManual. Failure to follow the instructions, proceduresand safety precautions in this manual can result inaccidents and injuries.

NEVER start the air compressor unless it is safe todo so. DO NOT attempt to operate the aircompressor with a known unsafe condition. Tag theair compressor and render it inoperative bydisconnecting and locking out all power at source orotherwise disabling its prime mover so others whomay not know of the unsafe condition cannot attemptto operate it until the condition is corrected.

Use and operate the air compressor only in fullcompliance with all pertinent OSHA requirementsand/or all pertinent Federal, State and Local codes orrequirements.

DO NOT modify the compressor except with writtenfactory approval.

Each day, walk around the air compressor andinspect for leaks, loose or missing parts, damagedparts or parts out of adjustment. Perform allrecommended daily maintenance.

Inspect for torn, frayed, blistered or otherwisedeteriorated and degraded hoses. Replace asrequired.

1.2 TOWING *

PREPARING TO TOW

A. Prior to hitching the air compressor to the towvehicle, inspect all attachment parts and equip-ment, checking for (I) signs of excessive wear orcorrosion, (II) parts that are cracked, bent,dented or otherwise deformed or degraded, and(III) loose nuts, bolts or other fasteners. Shouldany such condition be present, DO NOT TOWuntil the problem is corrected.

B. Back the tow vehicle to the compressor and posi-tion it in preparation for coupling the compressor.

C. If the compressor is provided with a drawbarlatched in the vertical upright position, carefullyunlatch drawbar and lower it to engage the cou-pling device. If not, raise drawbar with the jack toengage coupling device or otherwise couple thecompressor to the towing vehicle.

NOTE

OPERATOR IS REQUIRED TO READ ENTIRE INSTRUCTION MANUAL.

WARNINGDo NOT tow the compressor should its weight exceed the rated limit of the tow vehicle, as the vehicle may not brake safely with excess weight. See rated limit in tow vehicle Operator's Manual, and review its instructions and other requirements for safe towing.

* While not towed in the usual sense of the word, many of these instructions are directly applicable to skid-mounted portable air compressors as well.

SECTION 1

A. Make sure the coupling device is fully engaged,closed and locked.

B. If chains are provided, pass each chain throughits point of attachment on the towing vehicle;then hook each chain to itself by passing thegrab hook over (not through) a link. Cross chainsunder the front of drawbar before passing themthrough points of attachment on towing vehicle tosupport the front of drawbar in case it shouldaccidentally become uncoupled.

C. Make sure that the coupling device and adjacentstructures on the towing vehicle (and also, if uti-lized, chain adjustment, brake and/or electricalinterconnections) DO NOT interfere with orrestrict motion of any part of the compressor,including its coupling device, with respect to thetowing vehicle when maneuvering over anyanticipated terrain.

D. If provided, make sure chain length, brake andelectrical interconnections provide sufficientslack to prevent strain when cornering andmaneuvering, yet are supported so they cannotdrag or rub on road, terrain or towing vehicle sur-faces which might cause wear that could renderthem inoperative.

E. On two-wheeled models, fully retract front screwjack and any rear stabilizer legs. If a caster wheelis provided on the screw jack it is part of thescrew jack, and can not be removed. Follow thesame procedure for stowing away the wheeledjack as you would for the standard screw jack.Pull the pin connecting the jack to the drawbarand raise the screw jack to its full upright posi-tion. Rotate the screw jack to its stowed position,parallel to the drawbar, and reinsert the pin.Make sure the jack is secured in place prior totowing.

F. Make sure tires are in good condition and are thesize (load range) specified and are inflated to thespecified pressures. DO NOT change the tiresize or type. Also, make sure wheel bolts, lugs ornuts are tightened to the specified torques.

G. If provided, make sure all dual stop, tail direc-tional and clearance lights are operating properlyand that their lenses are clean and functional.Also, make sure all reflectors and reflecting sur-faces, including the slow moving vehicle emblemon compressors provided with same, are cleanand functional.

H. Make sure all service air hoses (not air brakehoses) are disconnected or are fully stowed andsecured on hose reels, if provided.

WARNINGThis equipment may be tongue heavy. DO NOT attempt to raise or lower the drawbar by hand if the weight is more than you can safely handle.

Use the screw jack provided or a chain fall if you cannot lift or lower it without avoiding injury to yourself or others. Keep hands and fingers clear of the coupling device and all other pinch points. Keep feet clear of drawbar to avoid injury in case it should slip from your hands.


CAUTIONRetract the front screw jack only after attaching the compressor to the tow vehi-cle. Raise the screw jack to its full up posi-tion and pull the pin connecting the jack to the drawbar. Rotate the screw jack to its stowed position, parallel to the drawbar, and reinsert the pin. Make sure the jack is secured in place prior to towing.

D. Keep a first aid kit handy. Seek medical assistancepromptly in case of injury. DO NOT ignore smallcuts and burns as they may lead to infection.

1.6.1 TIER 4 EMISSIONS MODULE - IF EQUIPPED

General Guidelines: Thermal Protection. The mainexhaust piping routes exhaust gas from the engine tothe Clean Emissions Module (CEM). Normaloperating temperatures can reach up to 530 °C (986°F). During regeneration of the Diesel ParticulateFilter (DPF), the Auxiliary Regeneration Device(ARD) will be in operation, this creating temperaturesabove normal engine exhaust temperatures. Gastemperatures during the regeneration period canreach 750 °C (1382 °F).

1.7 TOXIC AND IRRITATING SUBSTANCES

A. DO NOT use air from this compressor for respi-ration (breathing) except in full compliance withOSHA Standards 29 CFR 1920 and any otherFederal, State or Local codes or regulations.

T4 - WARNINGIncreased DPF skin temperature and exhaust gas temperature may occur in the event of an unex-pected engine/aftertreatment failure. An unex-pected failure of the engine/aftertreatment may increase temperature at the DPF as high as 900 °C (1652 °F) gas temperature and 750 °C (1382 °F) skin temperature. This may result in fire, burn, or explosion hazards, which may result in personal injury or death. Do not expose flammable mate-rial or explosive atmospheres to exhaust gas or exhaust system components during regenera-tion. The aftertreatment skin temperature and the gas temperature are difficult to measure and/or simulate and are dependent upon many factors including the following: the nature of the engine/aftertreatment failure, the design and packaging of the aftertreatment, the engine speed/load con-ditions, the condition of the aftertreatment and ambient conditions. Therefore, the potential tem-peratures are provided as a guideline even under conditions of unexpected engine and/or after-treatment failure. Proper precautions should be taken to ensure that the aftertreatment device is not mounted in close proximity to components that may be damaged by heat.

B. DO NOT use air line anti-icer systems in air linessupplying respirators or other breathing air utili-zation equipment and DO NOT discharge airfrom these systems into unventilated or otherconfined areas.

C. Operate the compressor only in open or ade-quately ventilated areas.

D. Locate the compressor so that exhaust fumes arenot apt to be carried towards personnel, air intakesservicing personnel areas or towards the air intakeof any portable or stationary compressor.

E. Fuels, fluids and lubricants used in this compres-sor are typical of the industry. Care should betaken to avoid accidental ingestion and/or skincontact. In the event of ingestion, seek medicaltreatment promptly. Wash with soap and water inthe event of skin contact. Consult Material SafetyData Sheet for information pertaining to the spe-cific fluid.

F. Wear goggles or a full face shield when addingantifreeze compound to air line anti-icer systems.

G. Wear an acid-resistant apron and a face shield orgoggles when servicing the battery. If electrolyteis spilled on skin or clothing, immediately flushwith large quantities of water.

H. Ethyl ether used in diesel engine ether startingaid systems is toxic, harmful or fatal if swallowed.Avoid contact with the skin or eyes and avoidbreathing the fumes. If swallowed, DO NOTinduce vomiting and call a physician immediately.

I. Wear goggles or a full face shield when testingether starting aid systems or when adding anti-freeze compound to air line anti-icer systems.Keep openings of valve or atomizer tube of etherstarting aid system pointed away from yourselfand other personnel.

J. If air line anti-icer system antifreeze compoundenters the eyes or if fumes irritate the eyes, theyshould be washed with large quantities of clean

water for fifteen minutes. A physician, preferablyan eye specialist, should be contacted immedi-ately.

K. DO NOT store ether cylinders or air line anti-icersystem antifreeze compound in operator’s cabsor in other similar confined areas.

L. The antifreeze compound used in air line anti-freeze systems contains methanol and is toxic,harmful or fatal if swallowed. Avoid contact withthe skin or eyes and avoid breathing the fumes. Ifswallowed, induce vomiting by administering atablespoon of salt, in each glass of clean, warmwater until vomit is clear, then administer twoteaspoons of baking soda in a glass of cleanwater. Have patient lay down and cover eyes toexclude light. Call a physician immediately.

M. When handling DEF (Diesel Emissions Fluid)wear protective clothing. Tools and clothing thatcome in contact with DEF must be cleaned.

1.8 ELECTRICAL SHOCK

A. Keep the towing vehicle or equipment carrier,compressor hoses, tools and all personnel atleast 10 feet (3 m) from power lines and buriedcables.

B. Stay clear of the compressor during electricalstorms! It can attract lightning.

INHALATION HAZARD!

Death or serious injury can result from inhaling compressed air without using proper safety equipment. See OSHA standards and/or any applicable Federal, State, and Local codes, stan-dards and regulations on safety equipment.

DANGER

-IMPORTANTIt is very important that all electrical connectors are protected from coming in contact with DEF. If not, there is a risk that DEF will cause oxidation in the wiring that is not possible to clean. The resulting oxidation will result in a wiring/connec-tion failure. Water and compressed air fail to remove DEF. If a connector has been in contact with DEF, it must be changed immediately to pre-vent the chemical from further migrating into the wiring cable harness, which happens at a speed of 0.6 m/h.

-WARNINGIn case of DEF contact with eyes or skin, the affected area must be thoroughly rinsed with lukewarm water. If you breathe any fumes, make sure and breathe fresh air.

DESCRIPTION2.1 INTRODUCTION

Sullair Portable Air Compressor models offersuperior performance and reliability while requiringonly minimal maintenance.

The compressor is equipped with a Sullair rotaryscrew compressor unit. Compared to othercompressors, the Sullair is unique in mechanicalreliability and compressor durability. No inspection isrequired of the working parts within the compressorunit.

As you continue reading this manual and come tolearn how the compressor operates and is cared for,you will see how surprisingly easy it is to keep aSullair compressor in top operating condition.

Read Section 5: MAINTENANCE to keep yourcompressor in top operating condition. Should anyproblem or question arise which cannot be answeredin this text, contact your nearest Sullairrepresentative or the Sullair Service Department.

2.2 DESCRIPTION OF COMPONENTS

Refer to Figure 2-1 and Figure 2-2. The componentsand assemblies of the Sullair Portable AirCompressor models are clearly shown. The packageincludes a compressor, diesel engine, exhaustsystem including an iT4 compliant emissions module,compressor/engine inlet system, compressor coolingand lubrication system, compressor dischargesystem, capacity control system, instrument paneland electrical system. The machine is also suppliedwith sound deadening insulation to lower noise

emissions to meet EPA or CE, most federal, state, orlocal noise requirements. The Sullair compressor unitis driven by an industrial engine designed to provideenough horsepower at rated conditions. Refer toEngine Operator’s Manual for a more detaileddescription of the engine.

The engine cooling system is comprised of aradiator, high capacity fan and thermostats. The highcapacity variable speed hydraulic fan blows airthrough the radiator, keeping the engine at theproper operating temperature while optimizing thefuel consumption by effectively adjusting the fanspeed to efficiently accommodate engine conditions.

The same fan also cools the fluid in the compressorcooling and lubrication system. While passingthrough the radiator, the fan air also passes throughthe compressor fluid cooler, which is mountedadjacent to the radiator. As air passes through thecooler, some of the heat of compression is removedfrom the fluid.

The same fan also cools the return fuel supply aswell as the fan drive hydraulic fluid. The coolers forthese circuits are integrated and mounted in front ofthe compressor cooler and radiator. The cooling fanis hydraulically driven. As air passes through theaftercooler heat is removed which was introduced bythe engine’s turbo charger. The engine is coupled tothe compressor unit with a non-lubricated, vulcanizedrubber disk and a drive flange-type coupling. Allcompressor models are supplied with a fuel tanklarge enough to keep the compressor runningthrough a full 8-hour shift.

2.3 SULLAIR COMPRESSOR UNIT, FUNCTIONAL DESCRIPTION

Sullair compressors feature the Sullair compressorunit, a single-stage, positive displacement, floodlubricated-type compressor. This unit providescontinuous compression to meet your needs.

Sullair compressors are factory-filled with SullairAWF lubricant. For more information on fluid fill, referto “Lubrication Guide—Compressor” on page 65.

Fluid is injected into the compressor unit hoses andmixes directly with the air as the rotors turn,compressing the air. The fluid flow has three basicfunctions:

1. As coolant, it controls the rise of air tempera-ture normally associated with the heat ofcompression.

2. Seals the clearance paths between therotors and the stator and also between therotors themselves.

3. Acts as a lubricating film between the rotorsallowing one rotor to directly drive the other,which is an idler.

After the air/fluid mixture is discharged from thecompressor unit, the fluid is separated from the air.At this time, the air flows through an aftercooler andmoisture separator, if equipped, then to your serviceline.

2.4 COMPRESSOR COOLING AND LUBRICATION SYSTEM, FUNCTIONAL DESCRIPTION

Refer to Figure 2-2. The compressor cooling andlubrication system is designed to provide adequatelubrication as well as maintain the proper operatingtemperature of the compressor. In addition to thecooler and fan, the system consists of a main filterand thermal valve. The fan is hydraulically driven,refer to Section 2.18 for more detail.

Fluid is used in the system as a coolant and alubricant. The fluid is housed in the receiver tank.

Upon start up, the fluid temperature is cool, androuting to the cooler is not required. The fluid firstenters the thermal valve and then flows on to thecompressor unit, bypassing the cooler. As thecompressor continues to operate, the temperature ofthe fluid rises and the thermal valve element beginsto shift. This forces a portion of the fluid to the fluidcooler. The cooler is a radiator-type that works inconjunction with the hydraulic fan. The fan forces airthrough the cooler removing the heat of compressionfrom the fluid. From the cooler, the fluid is routedback to the thermal valve.

Before the temperature of the fluid reaches the valveset point, cooled fluid is mixed with warmer fluid.When the temperature of the fluid reaches 170°F(77°C), the thermal element shifts completelycausing all fluid to flow to the cooler. The thermalvalve incorporates a pressure relief valve, whichallows fluid to bypass the cooler, if the coolerbecomes plugged or frozen. This helps assure thatfluid will continue to be provided to the compressorfor lubrication. After the fluid passes through thethermal valve it is then directed through the mainfluid filter. There, the fluid is filtered in preparation forinjection into the compression chamber and bearingsof the compressor unit. The filter has a replaceableelement and a built-in bypass valve which allows thefluid to flow even when the filter element becomesplugged and requires changing or when the viscosityof the fluid is too high for adequate flow. After thefluid is properly filtered, it then flows on to thecompressor unit where it lubricates, seals and coolsthe compression chamber as well as lubricates thebearings and gears.

NOTEWith a Sullair compressor, there is no main-tenance or inspection of the internal parts of the compressor unit permitted in accor-dance with the terms of the warranty.

2.5 CAPACITY CONTROL SYSTEM, FUNCTIONAL DESCRIPTION

Refer to Figure 2-3, Figure 2-4 and Figure 2-5. Thepurpose of the control system is to regulate theamount of air intake in accordance with the amountof compressed air demanded. The control systemconsists of an inlet valve, the high and low pressureregulators, the pressure reducing regulator, theblowdown/ running blowdown valve, the controller, a<ON> switch, and the <PRESSURE> selectorswitch.

START—0 TO 65 PSIG (0 TO 4.5 BAR)

Keep the <ON> switch to the “ON” position toinitialize the controller. Once the controller says“READY” on LCD, press <ON> switch to the“START” position. In the “START” position, the inletvalve is held closed by the springs in the inlet valve.The valve is cracked open by a vacuum in thecompressor and is allowed to build up to 65 psig (4.5bar). The reason for keeping the valve closed duringstart is to allow the engine to warm up without beingloaded by the compressor. Air pressure is containedin the receiver tank by the minimum pressure valvewhich has a set point of 65 psig (4.5 bar). At thispoint the valve opens allowing the air to pass to theservice valve. After the engine has warmed up themachine automatically transitions to “RUN” mode.

LOW PRESSURE/SINGLE PRESSURE—80 TO 100 PSIG (5.5 TO 6.9 BAR)

With the <PRESSURE> switch in the "LOW"position, and the controller in "RUN" mode, theservice valve can now be opened. Pressure from the60 psig (4.1 bar) reducing regulator opens up theinlet valve and the controller increases the enginespeed to full load (1800 rpm). As the demand for airdecreases, the controller commands the engine toreduce speed to idle (1400 rpm) and the inlet valvecloses, where it stabilizes until the air demand isrequired again. If left in the idle state (>1400 rpm) forperiods exceeding 10 minutes the engine rpm willdrop down further to a low idle state (1000rpm) untila demand for air is seen, in order to reduce fuelconsumption when not needed. If the machine is notmarked with an "H" or "HH", it is a single pressuremachine and will not have a <PRESSURE> switch.The machine will run as if it is in the "low" mode.

HIGH PRESSURE—80 TO 150 PSIG (5.5 TO 10.3 BAR) FOR “H” MODELS OR 80 TO 200

PSIG (5.5 TO 13.8 BAR) FOR “HH” MODELS

With the <PRESSURE> switch in the “HIGH”position, the low pressure regulator is blocked off bythe high/low solenoid valve allowing the highpressure regulator to take over control of themachine. The 60 psig (4.1 bar) reducing regulatorfully opens the inlet valve and the controllercommands maximum speed (1800 rpm) from theengine. As the pressure reaches the set point of thesystem the high pressure regulator cracks open andcloses the inlet valve and the controller returns theengine back to idle, until a demand for air is seen.

SHUTDOWN

The blowdown valve is normally closed. When thecompressor is shutdown, system pressure backs upto the inlet valve causing the check spring in the inletvalve to close the air inlet valve. This sends apressure signal to the blowdown valve causing it toopen and vent the pressure in the system. After thepressure is vented, the blowdown valve springreturns the blowdown valve to the closedposition.Compressor Discharge System, FunctionalDescription

Refer to Figure 2-3. The Sullair compressor unitdischarges a compressed air/fluid mixture into thereceiver tank.

The receiver tank has three functions:

1. It acts as a primary fluid separator.

2. Serves as the compressor fluid storagesump.

3. Houses the final fluid separator.

The compressed air/fluid mixture enters the receivertank and is directed against the tank side wall. Bychange of direction and reduction of velocity, largedroplets of fluid separate and fall to the bottom of thereceiver tank. The fractional percentage of fluidremaining in the compressed air collects on thesurface of the final separator element as thecompressed air flows through the separator. As moreand more fluid collects on the element’s surface, thefluid descends to the bottom of the separator. Areturn line (or scavenge tube) leads from the bottomof the separator element to the inlet region of thecompressor unit. Fluid collecting on the bottom of theseparator element is returned to the compressor bythe pressure difference between the areasurrounding the separator element and thecompressor inlet. An orifice (protected by a strainer)is included in this return line to help assure properflow.

The receiver tank is code rated. A minimumpressure/ check valve, located downstream from the


27

pressure during all conditions. This pressure isnecessary for proper air/fluid separation and properfluid circulation.

A minimum pressure/check valve at the outlet of thereceiver is installed to prevent compressed air in theservice line from bleeding back into the receiver onshutdown when the compressor is being run inparallel with other compressors tied to a large airsystem.

Fluid is added to the receiver tank via a capped fluidfiller. A fluid level gauge glass enables the operatorto visually monitor the receiver tank fluid level.

2.6 AFTERCOOLED AIR SYSTEM, FUNCTIONAL DESCRIPTION

The purpose of the aftercooled air system is tooperate the air compressor in conditions whencompressed air temperatures are required to be 10to 25 ̊F (5 to 13 ̊C) over ambient temperature. Theaftercooled feature of the compressor is controlled bya system of two ball valves which are standard on alllarge tier IV aftercooled compressor models. Byshifting both ball valves to the aftercooled positionthe air flow from the receiver tank is forced throughthe aftercooler producing aftercooled air. Moving theball valves to the standard position blocks air flow

through the cooler producing standard air. Theambient air, which is forced through the aftercoolerby the hydraulic fan, cools the compressed air as itpasses through the aftercooler core. Cooled airenters the moisture separator where condensation isremoved from the cooler air and discharged. Thiscondensation does carry some oil and it should bedisposed of properly in accordance with localregulations. A condensation drain port is located inthe frame on the curbside of the machine forconvenience of condensate removal. This drain portshould never be plugged or closed off in any way.From the moisture separator the compressed airgoes through the discharge filters (if equipped) andon to the service valve. WARNING

DO NOT remove caps, plugs and/or other components when compressor is running or pressurized.Stop compressor and relieve all internal pressure before doing so.

NOTEWhen operating at temperatures below freezing, the hydraulic fan will attempt to compensate for colder temperatures by slowing down or stopping. This will aid in allowing the aftercooler to be used in tem-peratures below freezing. When the After-cooler Discharge Temperature (ADT) approaches freezing, the controller will warn of an imminent freeze alert. After-cooled air should not be used in condi-tions where ADT is approaching freezing temperatures as this may cause damage to the aftercooled air discharge system.To operate in the non-aftercooled mode, position both aftercooler bypass valves to close off the aftercooled air circuit.

2.7 AIR INLET SYSTEM, FUNCTIONAL DESCRIPTION

Refer to Figure 2-4. The compressor inlet systemconsists of two air filters, a compressor air inlet valveand interconnecting piping to the engine andcompressor. Also, air filter restriction indicatorgauges are located next to the air filter housings.

The air filter is a 2-stage unit with a safety elementand dry element-type filter. This filter is capable ofcleaning extremely dirty air. However, in such cases,frequent checks of the air filter will be required.

Referring to the controller, the engine air filterrestriction sensor or the compressor air filterrestriction sensor will indicate when restriction of theair passing through the filter becomes too high.

At this time, change the air filter element. Theseindicators should be checked daily, after start-upunder normal conditions.

The compressor air inlet valve controls the amount ofair intake of the compressor in response to the airdemand.

2.17 ENGINE CONTROL MODULE, FUNCTIONAL DESCRIPTION

Diagnostic Fault Codes are provided to indicate anelectrical or electronic problem has been detected bythe ECM (Engine Control Module). In some cases, theengine performance can be affected when thecondition causing the code exists. More frequently,however, the operator cannot detect any difference inthe engine performance.

The controller indicates an engine performanceproblem has occurred whenever the Engine WarningLamp is flashing. The diagnostic code may indicate thecause of the problem, and should be corrected.

If the controller does not indicate a problem with theengine performance, but a diagnostic code is logged bythe ECM, an abnormal condition was detected that didnot affect performance.

If this is the case, unless there are several occurrencesof the code in a very short period of time, or, the ECMis indicating an Active Code at the present time, thereis most likely nothing wrong with the system.

If there is an error the controller should display a briefmessage containing the Failure Mode Indicator (FMI)and Suspect Parameter Number (SPN) in the LCD ofthe master gauge. This message helps to pinpoint thesource of the problem and aid in troubleshooting thecompressor.

Refer to Table 2-1 on page 47 for possibleperformance of active diagnostic codes.

NOTEOnly active diagnostic codes can be read in this manner. Logged diagnostic codes must be retrieved with an Electronic Service Tool.

2.18 HYDRAULIC FAN DRIVE SYSTEM

Refer to Figure 2-6. The compressor is equipped witha hydraulically driven fan to provide cooling airflowfor the compressor fluid, engine coolant, charge air,fuel, and hydraulic fluid. If equipped, cooling airflow isalso available to provide aftercooled discharge air.

The system includes a fan and vane motorpositioned in front of the main cooler pack andprovides the cooling airflow for the main coolerassembly. This fan also acts as the cooling airflowmechanism for aftercooled service air as well.

The fan motor is driven by dual pumps which arecoupled together and driven by the engine's auxiliary

gear drive. A variable displacement piston pumpdrives the fan motor while a fixed displacement gearpump pulls all the fluid from the reservoir and helpsto maintain a positive pressure at the inlet of thepiston pump. This arrangement allows a smaller fluidreservoir as well as more favorable inlet conditions tothe piston pump.

The fan is automatically varied depending on theambient, compressor, engine coolant, charge air,and package discharge temperature. This providesfuel savings by only running the fan as much asneeded to maintain proper operating temperatures.Additionally, load on the engine at startup is reducedassisting in cold starts and thermal cycling/shock iseliminated.

2.19 ELECTRICAL SYSTEM, FUNCTIONAL DESCRIPTION

Refer to Section 2.19. The electrical system iscomprised of not only the necessary equipmentrequired to operate the compressor, but also asystem to shut it down in the event of a malfunction.The components of the electrical system are anengine starter (with an integral solenoid), battery, abreaker protected alternator with a built-in voltageregulator, a compressor discharge temperaturesensor and receiver tank temperature switch (bothwill shut down the compressor should thecompressor temperature exceed 250°F [121°C]), anambient temperature sensor, and a fuel level sensor.This compressor also incorporates an engine coolantlevel sensor. This device is located in the bottom ofthe deaeration tank. It will shut the compressor downor prevent it from being started if the engine coolant

level drops too low. In addition, there is a starterprotection relay which prevents accidental starterengagement after the engine is running or wheneverthere is pressure in the receiver tank. Also, shouldfuel supply level drop near the bottom of the fueltank, the controller will shut down the machine beforethe engine runs out of fuel. There are also severalconnectors in the main harness that are designed toreceive wiring for factory options such as remotestart, engine air stop valve, and ether start system.The electrical system also incorporates a lockablebattery disconnect to be utilized for extended periodsof non use and during machine maintenance. In caseof emergency, an emergency stop switch is locatedadjacent to the controller on the canopy of themachine. Section 2.21, and Section 2.22 show thewiring diagrams for the controller and CEM unit.

2.23 ENGINE EXHAUST AFTERTREATMENT, FUNCTIONAL DESCRIPTION

Refer to Section 2.23. The Clean Emissions Module(CEM) or aftertreatment serves as the means ofachieving the Tier IV emissions requirements set forthby the EPA/ EU (69 FR 38957-39273, 29 Jun 2004) tobe phased in from 2008-2015. The module itselfconsists of a Diesel Particulate Filter (DPF), Muffler,Exhaust Outlet, DOC/Inlet Cap, Absolute pressuresensor, CEM Connector to ECM, Combustion AirValve, Exhaust inlet, Outlet cap, and a Caterpillar RShead. The basic function of the aftertreatment is toremove soot and other solid particulates from theexhaust via the DPF. The level of soot is monitored bythe engine and, when needed, the system willautomatically regenerate the DPF by raising thetemperature in the DPF through active combustion andreducing the soot to ash. This system allows the unit tokeep the particulate concentrations of the exhaust at

levels that comply with EPA/EU regulations.

Regeneration can be engaged by two methods:

1. Regeneration Switch (manual force/ inhibition)

2. ECU controlled (automatically managed)

Instead of expelling exhaust gases to the atmosphere astypical exhaust systems do, exhaust exits the engineturbocharger and enters the inlet of the CEM, where thelevel of soot loading in the DPF is measured by thepressure differential across the DPF. This information inconjunction with engine speed is used to determine ifconditions are correct to initiate an automaticregeneration cycle. During regeneration the CAT RSmodule adds diesel fuel and air from the turbocharger toburn the exhaust fumes and reduce the accumulatedsoot to ash. The table in Figure 4-1 describes thereaction of the system at various stages of the sootloading profile. For detailed CEM component informationplease see the Engine Operator's Manual

3.4 APPLICATION GUIDE

Refer to Figure 3-1. Sullair Air Compressors aresupplied with Sullair AWF which is heavy duty multi-viscosity, all weather fluid. Sullair AWF also allowsan extended change interval. The fluids in Section3.3: Lubrication Guide—Compressor on page 65 canbe used. Any of these oils are suitable underconditions where severe oil oxidations can occur.Water must be drained from the receiver tankperiodically.

In addition to AWF the compressor hydraulic tank isfilled from the factory with Sullair T4 hydraulic fanfluid. This is a specially formulated hydraulic fluidwhich meets all requirements of the hydraulic systemat ambient operating temperatures ranging from -20°F to 125°F.

In high ambient temperature and high humidityconditions, condensed moisture may emulsify withthe oil forming a “milky” color. ATF or SAE 10W isespecially prone to this condition. The fluid should bechanged if this condition develops.

When ambient conditions exceed those noted or ifconditions warrant use of other extended lifelubricants, contact Sullair for recommendations.

Sullair encourages the user to participate in a fluidanalysis program. This could result in a fluid changeinterval differing from that stated in the manual.Sullair offers a fluid analysis program for SullairAWF. Contact your local Sullair representative fordetails.

D-A Lubricant® Company Inc. offers an analysisprogram for users of D-A products and Sullair AWF.Contact your D-A Lubricant® representative fordetails.

OPERATION4.1 GENERAL

While Sullair has built into this compressor acomprehensive array of controls and indicators toassure you that it is operating properly, you will wantto recognize and interpret the readings which will call

for service or indicate the beginning of a malfunction.Before starting your Sullair compressor, read thissection thoroughly and familiarize yourself with thecontrols and indicators—their purpose, location anduse.

4.2 PURPOSE OF CONTROLS

CONTROL OR INDICATOR PURPOSE

Power ON Switch (Start Up) * The engine switch is used to both energize the compressor’s electrical system and engage the engine/starter. It also has a built-in anti-restart device that protects the starter from engaging while the engine is running. The switch must be turned back to the “off” position before the engine can be re-started.

Voltmeter * Monitors the condition of the batteries and the charging circuit. The normal reading is 24 to 48 volts.

Service Air Pressure Gauge * Continually monitors the pressure inside the receiver tank at various load and unload conditions.

Engine Temperature Gauge * Monitors the temperature of the engine water. The normal operating temperature should read approximately 160ºF to 210ºF (71ºC to 99ºC).

Controller * Depicts system related diagnostics. Can be used for system performance monitoring.

Compressor Temperature Gauge * Monitors the temperature of the air/fluid mixture leaving the compressor unit. The normal reading should be approximately 210ºF to 250ºF (99ºC to 121ºC).

System Pressure Sensor Prevents starter engagement when the air system is pressurized.

Fluid Level Sight Glass Monitors the fluid level in the receiver tank. Proper level is always visible in the sight glass. Check the level when the compressor is shutdown.

Receiver Tank Temperature Switch Opens the electrical circuit to shut down the compressor when then receiver tank temperature reaches 250ºF (121ºC).

NOTEWhen restarting the compressor, the controller will not allow restart until system pressure falls below 10 psig (0.7 bar) or less. More than 10 psig (0.7 bar) can put extra load on the starter.


70

Reducing Regulator Valve Provides regulated air pressure to the inlet valve.

Control Regulating Valve Provides an air signal to the inlet valve and engine to close the inlet valve and reduce engine speed to control air delivery according to demand.

Minimum Pressure/Check Valve Maintains a minimum of 65 psig (4.5 bar) in the compressor receiver tank. This valve restricts receiver air discharge from receiver/receiver tank when pressure falls to 65 psig (4.5 bar). Also prevents back flow into the receiver tank during upload conditions and after shutdown.

High/Low Pressure Selector Switch (only on dual pressure models) *

Select high pressure 150 psig (10.3 bar) or low pressure100 psig (6.9 bar) at instrument panel to correspond to operator’s needs.

Pressure Relief Valve Opens receiver tank pressure to atmosphere should pressure inside the receiver tank exceed the pressure relief valve setting.

Air Inlet Valve Regulates the amount of air allowed to enter the compressor. This regulation is determined by the amount of air being used at the service line.

Thermal Valve Regulates flow of fluid to and around the fluid cooler. Designed to maintain a minimum operating temperature; used for fast warm-up at start-up and to eliminate condensation during operation.

Blowdown Valve * Vents surplus receiver tank pressure to the atmosphere during operation and shutdown.

Coolant Level Switch Shuts the compressor down and/or prevents it from being started if the engine coolant level drops too low.

Hydraulic Fluid Sight Glass Monitors fluid level of hydraulic fan drive system. Proper level is filled to top of sight glass. Should be checked before every startup.

Hydraulic Fluid Level Switch Triggers a warning message when hydraulic system fluid level is low.

Hydraulic Fluid Temperature Sensor Triggers a warning message when the maximum hydraulic fluid temperature, 225°F (107°C) is exceeded. Normal temperature will depend on ambient temperature and system loading.

Regeneration Switch * To manually control the exhaust aftertreatment is in soot indicator levels of 15 - 105%

DPF Lamp * Indicates DPF is above 80% soot loading. Warns operator that regeneration is required.

Regeneration Inhibited Lamp * Indicates regeneration is inhibited by operator, application, or Cat ET.

High Exhaust System Temperature (HEST) Lamp *

Indicates that the exhaust aftertreatment is in active regeneration.

Cabin Light Switch * Manually turns interior compressor lighting on.

Menu select switch * Allows the user to make selections in the controller menu, and navigate the menu structure

Menu Toggle switch * Allows the user to scroll the menu options

CONTROL OR INDICATOR PURPOSE

4.3 COMPRESSOR START-UP PROCEDURE

1. Toggle the <ON> switch, located on the con-troller, to the “on” position. The controller willpower up and a self-diagnostic program willbe initiated. During the initiation process, thegauges will wag (the needles on each gaugewill sweep through its full scale) to verify allrelevant sensors are operational. Also, acommunication link will be established withthe engine ECU. During this time, severalmessages will be displayed on the panel.Some of these messages may not benoticed by the operator because the control-ler steps through the initialization phaserather quickly. However, the operator shouldsee the following messages during this step:

When the system has successfully initial-ized, the following message will be displayedon the LCD Graphic Display:

2. Prior to starting the unit, make certain thatthe Auxiliary Fuel Pump Switch is in the cor-rect position. If the fuel source is on-board orwithin the unit, the switch needs to be placedin the “on” position. If the fuel source is off-board or detached from the unit, the switchneeds to placed in the “off” position.

3. Toggle the <ON> switch to the “Start” posi-tion. You do not have to hold the switch in the“Start” position. The LCD panel will show thefollowing message:

Once the compressor has started, the unitwill enter a warm-up phase. At this point, theunit is not producing usable compressed airand the service valve should still be closed.The following message will be displayed onthe LCD panel:

Once the proper operating conditions aremet, the machine will automatically switchinto run mode and provide pressurized ser-vice air.

WARNINGIf the machine does not start successfully when starter disengages, the starter will automatically engage up to four more times after brief pauses to try and start the machine.


72

4.4 EXHAUST REGENERATION PROCEDURE

The aftertreatment constantly monitors the sootlevels of the exhaust gas. If soot levels detected bythe indicator reach above 80% the engine Electronic

Control Module (ECM) lights the DPF lamp , on

the controller screen, and should automaticallytrigger the ARD to ignite diesel fuel passing throughthe DPF until soot levels return to normal (< 10%).

During regeneration the HEST Lamp , on the

controller screen, should be lit. If for some reason theemissions module is not automatically engagedregeneration can be achieved, manually, by pressingand holding the <REGEN> Switch in the "force"

position , on the controller, for 15 seconds. This

will manually force the regeneration process at sootlevels of 15% - 105%. If regeneration is not desiredthe automatic regeneration process can be halted byengaging the <REGEN> Switch in the "inhibit"

position , on the controller. If regeneration is

inhibited the DPF Inhibited Lamp , on the

controller screen, should be lit. Regenerationinhibition should not be a regular practice, asallowing soot load percentages to get above 116%could cause the unit to abnormally shut down andfault the DPF. The Unit will NOT be able to function

until the faulted DPF is replaced. Force regenerationto reengage automatic feature. If for some reason theregeneration methods do not work and soot levelsare close too, at, or above 100% shut the unit downimmediately until this issue is resolved. Fortroubleshooting and next steps please refer toSection 5.17: Troubleshooting Guide on page 87,Engine Operator's Manual, or contact your CATdealer.

DANGERRegenerated exhaust gas can reach temper-atures as high as 1300-1400F. DO NOT come into direct contact with these gases.

WARNINGUnder no circumstances should the soot level reach above 140% as this will fault the DPF and halt unit operation until it is replaced. If for some reason the regenera-tion methods mentioned in this document do not work and soot levels are close to, at, or above 116%, shut the unit down immedi-ately until this issue is resolved.

4.5 SHUTDOWN PROCEDURE

1. Close the service valve.

2. Place the <ON> switch in the “off” position.The following message will be displayed inthe LCD graphic display:

3. The unit will continue to run, though it will notproduce usable air. At the end of the cooldown cycle, the engine will be shut down.The controller will stay powered up, and anew message will be displayed:

The controller will continue to monitor thesystem pressures and will not power downuntil all pressures drop below 10 PSI (0.7bar). This final process may take 3 to 5 min-utes. Operator interaction is not necessaryduring this time as the controller will auto-matically disconnect power to all systems sothat the battery is not inadvertently drainedafter shutdown.

WARNINGThe E-Stop (emergency stop switch) should be used only in the event of an emergency. Refrain from using the E-Stop to shut the machine down during normal operations. All usage of the E-Stop is logged in perma-nent memory for use by service technicians when troubleshooting a machine. Non-emergency use of E-Stop is considered equipment abuse and could void the manu-facturer’s warranty.

MAINTENANCE5.1 GENERAL

A good maintenance program is the key to longcompressor life. Below is a program that whenadhered to, should keep the compressor in topoperating condition. For engine maintenancerequirements, refer to the Engine Operator’sManual for a detailed description of serviceinstructions.

Refer to “Description Of Components” on page 21 fora detailed description of specific compressor systemcomponents. Prior to performing maintenance, readthe CIMA Safety Manual, if applicable.

5.2 DAILY OPERATION

Prior to starting the compressor, it is necessary toperform a daily inspection. Perform the followingmaintenance operations to prevent unnecessaryproblems.

1. Check the fluid level in the compressorreceiver tank. Should the level be low, simplyadd the necessary amount. If the addition offluid becomes too frequent, a simple problemhas developed which is causing this exces-sive loss. Refer to “Troubleshooting Guide”on page 87 under Excessive CompressorFluid Consumption for a probable cause andremedy.

2. Drain water from the fuel/water separator.

3. Check the fuel level in the fuel tank.

4. Check the engine oil level.

5. Check the engine coolant level.

6. Check the hydraulic fluid level

After a routine start has been made, it is necessary toperform an inspection to ensure all operations areperforming correctly. Perform the followinginspections to prevent unnecessary problems.

1. Observe the instrument panel gauges andbe sure they monitor the correct readings fortheir particular phase of operation.

2. After the compressor has warmed up, it isrecommended that a general check on theoverall compressor and instrument panel bemade to assure that the compressor is run-ning properly.

3. Check soot load percent

4. Check the air filter restriction gauges. Shouldthey indicate restriction, replace the ele-ments immediately. Refer to “Air filter assem-bly.” on page 78.

5.3 ENGINE COOLANT

The coolant provided with Sullair portable aircompressors is ethylene glycol based, 50/50 mixture,colored green, and should never be mixed with acoolant of a different color such as yellow, orange, orpink. If radiator coolant is to be added, for anyreason, be sure that the coolant added is the sameas what is in the cooling system, as well as what isrecommended. Refer to the Maintenance Section ofthe Engine Operators Manual for proper enginecoolant specifications and instructions. Ensure thatthe proper coolant is used when adding enginecoolant to the machine and never mix different colorcoolants. An engine originally filled with aconventional green coolant should not be “upgraded”to an extended life coolant unless the cooling systemis completely flushed and filled with water severaltimes to remove all traces of the old coolant. If youare not sure of the coolant that is installed originally itis always best to flush the system using water as abase until flushed water is clear. Then, fill the system

CAUTIONDO NOT remove caps, plugs and/or other components when compressor is running or pressurized. Stop compressor and relieve all internal pressure before doing so.


76

with the recommended coolant using only one brand/type. Cross contamination which is caused by addingdifferent types of engine coolants will result in thecoolant additives to deplete (dropout); thus leavingradiator surfaces unprotected. Corrosion to radiatorsurfaces will occur, thus reducing radiator lifeexpectancy.

5.4 MAINTENANCE AFTER INITIAL 50 HOURS OF OPERATION

After the initial 50 hours of operation, a few simplemaintenance routines can rid the system of anypossible foreign materials, if any. Perform thefollowing maintenance operations to preventunnecessary problems.

1. Clean the return line (scavenge line) orificeand strainer.

2. Change compressor fluid filter.

3. Change the hydraulic system fluid filter ele-ment.

4. Check Engine Operator’s Manual forrequired service.

5.5 MAINTENANCE EVERY 100 HOURS

After 100 hours of operation, it will be necessary toperform the following:

1. Check the battery level and fill with water ifnecessary.

2. Check Engine Operator’s Manual forrequired service.


Perform the following after every 250 hours ofoperation:

1. Check alternator belt tension and adjust ifneeded.

2. Clean the radiator and cooler exterior.Depending on how contaminated the atmo-sphere may be, more frequent cooler and

CAUTIONThe radiator and engine cooling system must be drained and flushed periodically. The required change interval is determined by the following table. Refer to the OEM Engine Man-ual for more information. Replace the coolant with a solution of 50% ethylene glycol and 50% water or as required for your geographic location. DO NOT use a leak sealing type of anti-freeze. Should a 100% water solution be used, a non chromate rust inhibitor must be added.

CAUTIONDispose of fluids in accordance with applicable federal, state and local regulations.

GENERAL MAINTENANCE - ELECTRIC BRAKE BRAKE ADJUSTMENT

Most Dexter 12 1/4" electric brakes have a self-adjusting feature. If manual adjusting is required, usethe following procedure:

Brakes should be adjusted (1) after the first 200

miles of operation when the brake shoes and drumshave "seated," (2) at 3,000 mile intervals, (3) or asused and performance requires. the brakes shouldbe adjusted in the following manner:

1. Jack up the trailer and secure on adequatecapacity jack stands. Follow trailer manufac-turer's recommendations for lifting and sup-porting the unit. Make sure the wheel anddrum rotates freely.

2. Remove the adjusting hole cover from theadjusting slot on the bottom of the brakebacking plate.

3. With a screwdriver or standard adjustingtool, rotate the star wheel of the adjusterassembly to expand the brake shoues.Adjust the brake soes out until the pressureof the linings against the drum makes thewheel very difficult to turn.

4. Then rotate the star wheel in the oppositedirection until the wheel turns freely with aslight lining drag.

5. Replace the adjusting hole cover and lowerthe wheel to the ground.

6. Repeat the above procedure on all brakes.For best results, the brakes should all be setat the same clearance.

BRAKE CLEANING AND INSPECTION

Your trailer brakes must be inspected and servicedimmediately if a loss of performance is indicated.With normal use, servicing at one year intervals isusually adequate. With increased usage, theis workshould be done more frequently as required.Magnets and shoes must be changed when theybecome excessively worn or scored, a conditionwhich can reduce vehicle braking.

Clean the backing plate, magnet arm, magnet, andbrake shoes. Make certain that all the parts removedare replaced in the same brake and drum assembly.Inspect for any loose or worn parts, stretched ordeformed springs and replace as necessary.

BRAKE LUBRICATION

Before reassembling, apply a light film of grease oranti-seize compound on the brake anchor pin, theactuation arm bushing and pin, and the areas on thebacking plate that are in contact with the brake shoesand magnet lever arm. Apply a light film of grease on

CAUTIONDo not lift or support the trailer on any part of the axle or suspension system. Never go under any trailer unless it is properly sup-ported on jack stands which have been rated for the load. Improperly supported vehicles can fall unexpectedly and cause serious injury.

WHEEL BEARING LUBRICATIONRefer to Figure 5-4. Proper lubrication is essential to the proper functioning and reliability of your portable compressor axle. The wheel bearings are lubricated through the use of a oil-bath. See Table 5-1 for company approved oil sources. Oil level should be checked every month. The oil can be filled through the rubber plugged hole in the clear end cap. Oil should be replaced every year or 12,000 miles,

CAUTIONPOTENTIAL ASBESTOS DUST HAZARD!Some older brake linings may contain asbestos dust, which has been linked to serious or fatal illnesses. Certain precau-tions need to be taken when servicing brakes:

1. Avoid creating or breathing dust.

2. Avoid machining, filing or grinding thebrake linings.

3. Do not use compressed air or drybrushing for cleaning (dust can beremoved with a damp brush).

CONTROL SYSTEM ADJUSTMENT—SINGLE PRESSURE

Refer to Figure 5-10. Prior to adjusting the controlsystem, it is necessary to determine the desiredoperating pressure range as well as the maximumpressure at which the machine is to operate. Thispressure must not exceed the maximum operatingpressure which is stamped on the machine serialnumber plate.

1. Start the machine and let it warm-up andenter full “run” mode.

2. Open service valve slightly until engine triesto speed up. Slowly close the service valve.With service valve closed, check and adjustthe pressure at the reducing regulator to aminimum of 60 psig (4.1 bar) and not toexceed 85 psig (5.2 bar). With service valve

still closed adjust the back pressure regula-tor so the service pressure is between 115 to125 psig (7.9 to 8.6 bar) for standardmachines, 165 to 175 psig (11.4 to 12.1 bar)for "H" machines, and 190 to 200 psig (13.1to 13.8 bar) for "HH" machines with theengine at 1400 rpm. Open the service valveto load the compressor to maintain a servicepressure of 100 psig (6.9 bar) for standardmachines, 150 psig (10.3 bar) for "H"machines, and 175 psig (12.1 bar) for "HH"machines. Operating speed should be 1800RPM on the controller panel. If not, repeatstep, or adjust the unload service pressureup or down as needed until desired pressureis maintained and engine speed is 1800 rpm.

CONTROL SYSTEM ADJUSTMENT—DUAL PRESSURE

Refer to Figure 5-9. Prior to adjusting the controlsystem, it is necessary to determine the desiredoperating pressure range as well as the maximumpressure at which the machine is to operate. Thispressure must not exceed the maximum operatingpressure which is stamped on the machine serialnumber plate.

1. Start the machine and let it warm-up andenter full “RUN” mode.

2. Open service valve slightly until engine triesto speed up. Slowly close the service valve.With service valve closed, check and adjustthe pressure at the reducing regulator to aminimum of 60 psig (4.1 bar) and not toexceed 85 psig (5.2 bar). With service valvestill closed, and the <PRESSURE> switch inthe “Low” position, adjust the low-pressureback-pressure regulator so the service pres-sure is between 115 to 125 psig (7.9 to 8.6bar) with the engine at 1400 rpm. Open theservice valve to load the compressor tomaintain 100 psig (6.9 bar) discharge pres-sure. Operating speed should be 1800 RPMon the controller panel. If not, repeat step,but adjust the unload service pressure up ordown as needed until 100 psig (6.9 bar) ismaintained when engine speed is 1800 rpm.

3. For 150 psig (10.3 bar) “H” machines, turnthe <PRESSURE> switch to “High” position.Close the service valve and set the “High”pressure control regulator to maintain 165 to175 psig (11.4 to 12.1 bar) discharge pres-sure. Open the service valve to maintain 150psig (10.3 bar) and check for 1800 RPM full-load speed. If lower speed is observed, raisethe setting of the low pressure control regu-lator until rated speed is achieved.

4. For 175 psig (12.1 bar) “HH” machines, turnthe <PRESSURE> switch to “High” position.

Close the service valve and set the “High”pressure control regulator to maintain 190 to200 psig (13.1 to 13.8 bar) discharge pres-sure. Open the service valve to maintain 175psig (12.1 bar) and check for 1800 RPM full-load speed. If lower speed is observed, raisethe setting of the low pressure control regu-lator until the desired speed is achieved.

5. For 200 psig (13.8 bar) “HH” machines, turnthe <PRESSURE> switch to “High” position.Close the service valve and set the “High”regulator to 215 to 225 psig (14.8 to 15.5bar) discharge pressure. Open the servicevalve to maintain 200 psig (13.8 bar) andcheck for 1800 RPM full-load speed. If lowerspeed is observed, raise the setting of thelow pressure control regulator until thedesired speed is achieved.
