• Main Blower (1) is in the main blower compartment next to the Main Electric Panel (2) and Compressor
Compartment (3). Some models could be equipped with two main blowers.
• 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. Main manual by-pass
damper (10a) is used to adjust airflow across air coils (evaporator, reheat and space heating coils).
• 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 is usually mounted directly on the dehumidifier’s supply air duct connection.
o Gas heater (duct heater or boiler package), if provided, normally is installed externally (not shown).
