PoolPak PCP Series – Indoor OMM 18 September 2020
• Min Outdoor Air (OA) Opening (4) is optionally equipped with a motorized damper and filter(s). The Manual
OA Damper (5) is usually used to set proper amount of outdoor air intake.
• Refrigeration coils - Evaporator (7) and Reheat (internal condenser) (8) - are located directly downstream of
the Main Filter Rack (9).
o Evaporator Bypass Damper (10) is located next to the evaporator coil. It helps to control compressor
suction pressure by adjusting the amount of air, bypassing the evaporator.
• Space heater (11) location, if the dehumidifier is equipped with one, may vary:
o Hot water coil is usually located directly downstream of the reheat coil;
o Electric heater may be in the same place as the hot water coil or mounted directly on the
dehumidifier’s supply air duct connection.
o Gas heater normally is installed externally.
• Compressor (13), Receiver (14) and other components are located within the Compressor Compartment (3).
o If the dehumidifier has the standard pool water heating option, the compressor circuit includes the
coaxial pool water heat exchanger (15) and refrigeration pool valve.
o If the dehumidifier has the water-cooled air conditioning option (equipped with fluid cooler or
connected to external water-cooling source), the compressor circuit also includes the plate heat
exchanger (16)).
• Main Electric Panel contains Main Control Board (17), Operator Panel (18) and other electrical components.
