WHOLE HOME DEHUMIDIFICATION

The Aprilaire

Dehumidifier controls the humidity level in your entire home. A powerful blower inside the dehumidifier draws air into the cabinet,

filters the air and removes moisture, then discharges the dry air into the HVAC system or dedicated area of the home. Inside the cabinet, a

sealed refrigeration system removes moisture by moving the air through a series of tubes and fins that are kept colder than the dew point of

the incoming air. The dew point is the temperature at which moisture in the air will condense, much like what occurs on the outside of a cold

glass on a hot summer day. The condensed moisture drips into the dehumidifier drain pan to a drain tube routed to the nearest floor drain or

condensate pump. After the moisture is removed, the air moves through a second coil where it is reheated before being sent back into the home.

The air leaving the dehumidifier will be warmer and drier than the air entering the dehumidifier.

Setting the Desired Humidity Level The dehumidifier on-board control will display the humidity setting when not running, and displays the measured humidity when running. 90-1853 The UP and DOWN arrow buttons allow the humidity level to be set from 40% to 80% relative humidity. Use the ON/OFF button to turn the dehumidifier ON or OFF. Set the control at 55%RH when first installed. Allow the dehumidifier to run until it reaches the setting before deciding if you want to change the setting.

external control OPTIONS Your Aprilaire dehumidifier can be controlled with an optional external control that is conveniently located in the living space. The Aprilaire Model 76, 8620, and 8910 are recommended controls. The Model 76 is a dedicated dehumidifier control and the 8620 and 8910 integrate dehumidification control as part of the thermostat minimizing the number of controls on the wall. The Model 76 can also act as a remote control if the dehumidifier is located in a crawl space.

Maintenance (continued) Check the Drain The drain should be checked annually to ensure there are no blockages or air lock in the drain system. If the unit is not draining properly, have it checked by a qualified service professional. CAUTION Do not use spray solvents or cleaners on or near the inlet side of the dehumidifier. If desired, apply cleaner to a cloth and use to clean the cabinet.
