2.5. Auxiliary Heat (Duct Heater), If Required

In certain climates or regions and with some pool enclosures, construction materials,

additional supplemental room heat is required, then an electric duct heater, duct furnace

or hot water coil should be installed down stream in the supply air duct system of the

DryAire dehumidifier.

When a duct heater (field supplied) is required to supply supplemental or auxiliary heat to

satisfy the total heat loss of the pool area refer to equipment 24v wiring diagram attached

to inside of electrical panel.

2.6. Outdoor Installation

When the dehumidifier is located outdoors, or in an un-conditioned space where ambient

temperatures can fall below 45°F, such as an attic, you must use an outdoor-rated

dehumidifier (optional features) to included weatherproofing and thicker insulation. Special

precautions must be taken with the condensate drain pan and piping to prevent winter

freeze up.

Contractor must heat tape the condensate drain pan, P-trap and all exposed drain piping

connections. Heat tape to have exterior power source from DryAire dehumidifier.

The blower indicator switch on the automatic thermostat must be set in the “ON” position

which will allow the system blower to run continuously. This will circulate 80°F room air

through the dehumidifier during the winter season.
