manual abstract
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/or 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 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. SETTINg THE DESIRED HUMIDITy LEVEL SETTINg THE DESIRED HUMIDITy LEVEL At the inlet side of the unit, a humidity control knob sets the desired humidity level between 1 (less dry, dehumidifier runs less) and 7 (more dry, dehumidifier runs more), or can be used to turn the dehumidifier OFF. The ON/OFF switch on the front of the unit should be left ON and only be used to turn the dehumidifier off when performing maintenance (see page 4 for maintenance requirements). Set the control at a Normal level, between 3 and 4, when first installed. Allow the dehumidifier to run for 24 hours before deciding if you want to change the setting. • If you prefer the air to be more dry, increase the setting; this will increase the amount of time that the dehumidifier runs. • If you prefer the air to be less dry, decrease the setting; this will reduce the amount of time that the dehumidifier runs. The settings on the dial can be approximated to relative humidity (RH) using the table to the right. Your comfort is the best measure of how to adjust your setting. When first installed, your dehumidifier has to remove all the moisture that is initially in your home. The home acts like a sponge so the moisture in the materials of your home is at the same level as the air. After drying the air, the materials of the home will release moisture back into the air until they are again at the same level. As a result, it is not uncommon for the dehumidifier to operate for an extended period when first installed.

ENERgy SAVINgS TIP Adjust the setting to be as low as is comfortable to reduce dehumidifier run time – if it feels clammy or smells damp, raise the setting. To save energy, turn the dehumidifier setting to OFF when you open your windows just as you would with air conditioning. WHEN DOES THE DEHUMIDIFIER TURN ON? The dehumidifier turns on the first time that the blower in your home heating and cooling system turns on (i.e. air conditioning comes on or you run the fan continuously) within the Cycle Period. Your installing contractor set the Cycle Period when the dehumidifier was first installed; it may be set for once every 30 minutes, once per hour, once every two hours or once every three hours. If the heating and cooling system blower does not turn on within the Cycle Period, the dehumidifier will turn itself on at the end of the Cycle Period. The Cycle Period setting determines how frequently the dehumidifier measures the humidity level in the air; once per hour is usually sufficient to maintain comfort. If you want the dehumidifier to check the humidity level more or less often, contact your installing contractor. An optional Model 75 Control can be mounted directly in the home for easy access to the humidity setting and measured humidity in the living space. The Model 75 continuously measures the humidity level to turn on the dehumidifier on-demand. Consult your in...
