MECHANICAL INSTALLATION

Lifting and Rigging Procedures• Determine the approximate center of gravity before lifting the unit. Consult unit design drawings

provided in the submittal documents to center total weight and weight distribution.

• Never assemble split sections before lifting them to the installation location. Always lift sections as received from the factory.

• Lift sections using the provided lifting lugs

• To avoid damage, do not attach intake or exhaust hoods prior to lifting the unit into place.

Unit Assembly (Split Units Only)Under special conditions, the unit may be split into two or more sections to ease the installation process. Base angles are attached using 3/8” bolts, and inside angles are bolted using 5/16” bolts. Ensure that all provided holes are used. Caulk seams on the outside of the unit to make the join air-tight. Install the standing seam roof rib.

Duct ConnectionsAll duct connections should be installed in accordance with local and national standards. To ensure the highest fan efficiency, duct turns and transitions should be made to minimize air friction losses and turbulence. See supplied unit drawing from the submittal for location and size of unit duct connections. Use only flexible duct connectors to connect to the unit.

Installation


Piping and Unit ConnectionsSee the unit label for unit connection line sizes. The installer must endeavor to ensure that all industry standards for refrigeration component installation are met. This includes but is not limited to; proper line sizing, materials, nitrogen purging, brazing with Silfos 5 or better (NO SOFT SOLDER), evacuation, cleanliness, traps, long radius elbows and system charging.

Drain Pans - Condensate DrainThe dehumidifier is a draw through configuration as a result the entire cabinet is under negative pressure. Without a P-trap, condensate will not drain and the unit will overflow into your mechanical room.

• Per Figure 1 pitch the condensate drain line a minimum of 1/8” per linear foot, and support the pipe with code approved hangers at least every 5 feet.

• If the drain line passes through an unconditioned space, heat tracing is required to prevent the condensate in the drain from freezing.

When gravity disposal is not possible, a condensate pump can be used. Follow the pump manufacturer’s installation instructions.

Figure 1Drain Pans - Condensate Drain

Field Installed Outdoor Air Cooled Condensers and Fluid CoolersThis condenser is used in air conditioning mode where it rejects unneeded heat from the space to outdoors. Proper installation is essential to ensure it can function as intended. Proper airflow and refrigerant piping are paramount. Ensure an appropriate maximum ambient air temperature has been specified. Ensure the unit has proper airflow per Figure 2. A perimeter of free area equal to its width must be provided. Use line sizes as specified by PoolPak. To avoid potential seasonal system charge problems, ensure the installed line lengths are never longer than indicated on the plans and specifications. If the condenser is installed above the dehumidifier, ensure the hot gas line has proper oil traps. Contact PoolPak if the condenser is installed more than eight (8) feet below the dehumidifier. The installer must endeavor to ensure that all industry standards for refrigeration component installation are met. This includes but is not limited to; proper line sizing, materials, nitrogen purging, brazing with Silfos 5 or better (NO SOFT SOLDER), evacuation, cleanliness, traps, long radius elbows and system charging. Install the remote condenser on a level, hard surface. Bolt the condenser in place.

Installation


Refrigerant Piping of Remote CondensersPCP series dehumidifiers are equipped with isolation valves and access valves located in the blower compartment. Do not open the isolation valves until all exterior piping is leak checked and evacuated. The last outdoor condenser vacuum can be broken with liquid refrigerant (R-410A). Monitor the exact amount of refrigerant added, as the total system charge must be per the unit nameplate. The PCP series dehumidifiers have refrigerant pipe stubs for the line set connection inside the cabinet. Use standard commercial refrigeration piping practices when installing the refrigeration piping between the dehumidifier and the remote air-cooled condenser.

• Hot Gas and Liquid line sizes should be per unit nameplate. The stubs inside the unit will be the correct sizes for line lengths up to 50’

• Do not exceed 50’ total line length or install the condenser more than 8’ below the unit. Consult PoolPak before installing the outdoor air-cooled condenser more then 8 feet below or more than 50 feet away from the dehumidifier.

• Per Figure 3, install an oil trap at the start of and at every 15 feet of vertical lift in the hot gas discharge line as shown. Pitch horizontal lines a minimum of 1/2” every 5 feet in the direction of flow. All piping must be clean and de-burred. Keep copper chips and foreign materials out of the tubing. A nitrogen purge while brazing is paramount to reduce the chances of oxidation in the pipes.

• Keep the Hot Gas and Liquid lines a minimum of 2” apart to prevent heat transfer. Insulate the hot gas line in all areas where a person may come in contact with the line and be in danger of a burn.

• When all piping work is complete, check for leaks by pressurizing the remote condenser and line set with dry nitrogen. If no leaks are detected, the circuit is ready to be evacuated. Evacuate the condenser and piping to a minimum 250 microns. Isolate the piping for ONE HOUR to verify that the system is free from leaks, moisture, and non-condensables. For further details on proper vacuum and evacuation procedures, see section H – Routine Maintenance.

Figure 2. Typical Outdoor Condenser Installation

Installation


Charging of Remote CondensersOnce a proper evacuation has been accomplished the system is ready for charging. The outdoor air-cooled condenser requires a field charge by the installing contractor. The field charge required depends on the size of the condenser and the length of the piping. The unit nameplate will show the exact field charge required. The last vacuum can be broken with liquid refrigerant. Monitor the exact amount of refrigerant added, as the total system charge must be per the unit nameplate. Connect the control wiring to the terminals provided inside the electrical compartment of the dehumidifier and outdoor condenser. Refer to the low voltage wiring schematic for details. The condenser fan(s) will not operate until this is complete. Once you have charged and checked the condenser and line set for leaks, open the service valves located in the compressor compartment of the dehumidifier. There is an access valve in the liquid line after the pump down valve. The pump down valve can be manually closed during start-up mode via the controller. Add only as much refrigerant as is needed to get to the total charge indicated on the nameplate. Never charge liquid into the suction line access valve! The receiver has 2 sight glasses with float balls to help ensure the maximum and minimum refrigerant levels are easily met.

Fluid Cooler InstallationFluid cooled units come with a separate pump for the fluid loop. PVC piping is highly recommended for fluid cooler installation.

PLACING THE EQUIPMENT

Although the design of the unit roof mounting supports is usually done by an architect or structural engineer, it is coordinated with dimensional data supplied by the manufacturer. Recommended mounting details and dimensions which the mechanical contractor may use for verification of correct steel roof curb dimensions and electrical and gas service locations on the job site before the arrival of the equipment are furnished by the manufacturer. If this is done, time and money may be saved when the equipment arrives. If any details are found to be questionable, consult with the local Sales Representative or the factory directly.

When the equipment arrives, the dehumidifiers are chained to a flat bed trailer. Coordinated arrival of the equipment and the crane should have previously been arranged with the factory. This is necessary if extra unloading costs are to be avoided. The truck driver will unchain the units. NOTE: It is the responsibility of the contractor to provide the necessary personnel to unload and rig the equipment to the roof and the manufacturer will assume NO additional costs incurred by the failure of the contractor to meet this responsibility.

Units which are mounted on a roof curb must utilize a curb gasket material. The curb gasket acts as a moisture and weather seal between the unit and the roof curb. An ample supply of curb gasket is shipped inside the unit. A label on the unit will identify exactly where in the unit the gasket may be found. It is the responsibility of the contractor to install the curb gasket. The curb gasket should be installed around the perimeter of the curb and any duct opening cross members.

Each unit is provided with lifting brackets attached to the unit base frame for the purpose of attaching lifting hooks (see drawing). It is the responsibility of the crane operator to provide and utilize adjustable cable spreader bars. The spreader bars must be placed as close to the top of the unit as possible. The spreader bars must also be wider than the unit so that the cable will angle away from the unit. This will prevent damage to the cabinet. The manufacturer will not be responsible for damage to the equipment due to improper rigging procedures.

Drawing depicts recommended spreader bar configuration. Actual number of lifting lugs may vary. Consult factory.

Sequence of Operation

The system shall be designed and sized to maintain the specified space conditions

System Startup

Power is turned on or the system is restarted

After a short initial delay to allow the sensors to stabilize, the blower starts and operates continuously

Based on sensor feedback, the system shall begin or resume operation based on the sequence below

Airside Configuration

The system continuously delivers the specified supply air volume to the natatorium

The minimum exhaust air volume is set to meet the engineer's schedule.

The minimum outdoor air volume is set to meet the engineer's schedule.

Dehumidification Mode

The return air relative humidity is above the humidity setpoint

Return air dewpoint is above dewpoint setpoint.

The compressor enters the Compressor Start sequence

If the system cannot maintain the relative humidity below setpoint, the second compressor circuit will start

Compressor waste heat is rejected into a glycol fluid loop which feeds the reheat coils and the air conditioning air-

cooled heat exchanger in parallel.

The reheat coils are fully modulating (0-100%). The reheat output will modulate to maintain the space temperature at

set point year-round. Reheat coils that are on off or only give heat from one circuit are not acceptable since they do not

closely match the requirement of the space and cause swings in space conditions.

Air Conditioning Mode

The return air temperature is above the room temperature setpoint

The compressor starts, if not already operating in Dehumidification Mode

Excess compressor hot gas is diverted to a fluid-cooled heat exchanger. Up to 100% of compressor heat is rejected

into the glycol fluid loop which is pumped outdoors to an outdoor air-cooled heat exchanger for 100% heat rejection at

summer design ambient conditions

100% of compressor heat is rejected at the outdoor air-cooled heat exchanger on a summer design day. On off-peak

days, the air reheat output will modulate to maintain the space temperature at the set point

If the system cannot maintain the return air temperature setpoint, the second compressor will start

Space Heating Mode

The return air temperature is below the room temperature setpoint

The microprocessor space heating output signal (0-10 volts) is sent to the heating coil controller. The signal output will

regulate based on the return air temperature

Pool Water Heating Mode

The return pool water temperature is below the pool water setpoint and the pool water flow switch or minimum

temperature differential is satisfied.

If the compressor is already operating due to a Dehumidification or Air Conditioning demand, the control valves will

divert the compressor hot gas through the coaxial heat exchanger to heat the pool water, with the remainder rejected at

the air reheat coil or the AC heat exchanger. Auxliiary pool water heater will be engaged as a second stage as needed.

If there is no pre-existing demand for the compressor to operate, the microprocessor sends a signal to the auxiliary pool

water heater (remote by others) to operate. The compressor will not operate solely for a pool water heating demand

unless specifically configured to do so at the controller

Factory-installed relay(s) and factory furnished, field-installed pool water temperature sensor(s) are provided to enable
