Thank you for your purchase of the Aprilaire® Dehumidifier. Your dehumidifier is designed to remove humidity from your home, maintaining the humidity at a comfortable level and reducing the unwanted effects of high humidity. Use your Aprilaire Dehumidifier to control the humidity that comes into the home from opening doors and infiltration (i.e. outdoor air entering through the building envelope). You can reduce the amount of humidity that enters the home by closing windows, doors, and fireplace flues when the outdoor humidity is high and by drying clothes outside. Whirlpool tubs and saunas will also increase the amount of humidity in the home. Direct exhaust from kitchen vents and bath fans is the best means of controlling humidity due to cooking and showers/baths. Your Aprilaire Dehumidifier is not designed for pool rooms or to eliminate or reduce condensation on windows in the winter and works best when the indoor temperature is above 65°F (18°C).

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 and removes moisture from the air, and then discharges the dry air to 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 – no need to empty a tub every day. After the moisture is removed, the air moves through a second coil where it is reheated before being sent back into the home. It is normal for the air leaving the dehumidifier to be warmer than the air entering the dehumidifier.
