Aprilaire E070 Print Professional Grade Crawl Space Dehumidifier
PLEASE LEAVE THIS MANUAL WITH THE HOMEOWNER.
OVERVIEW
CRAWL SPACE DEHUMIDIFICATION
The Aprilaire® dehumidifier controls the humidity level in your crawl space. A powerful blower inside the dehumidifier draws air into the cabinet, filters the air and removes moisture, then discharges the dry air into the crawl space. 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 space. 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. 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 59%RH when first installed. Allow the dehumidifier to run until it reaches the setting before deciding if you want to change the setting.
- If you prefer the air to be more dry, decrease the humidity setting.
- If you prefer the air to be less dry, increase the humidity setting.
HOW DOES THE DEHUMIDIFIER WORK?
Once per hour the dehumidifier will measure the humidity level of the air and compare it to the humidity setting. If the humidity in your crawl space is higher than the setting, the dehumidifier will dehumidify the air until the humidity level drops 3%RH below the setting.
- When the dehumidifier turns on, the blower circulates the air for 3 minutes before measuring the humidity level of the air. The on-board control will display AIR SAMPLING, along with the measured humidity on the control screen.
- If the humidity of the air is higher than the setting, the compressor turns on and the control will display DEHUMIDIFYING, along with the measured humidity on the control screen.
EXTERNAL CONTROL OPTIONS
Your Aprilaire dehumidifier can be controlled with an optional Aprilaire Model 76 Control. Install theModel 76 in your living space and make changes to the dehumidifier setting or find out what the humidity level is in the crawl space from the comfort and convenience of the living space. Refer to the Model 76 Owner’s Manual for operating instructions. Aprilaire owner’s manuals are available at www.aprilaire.com. If you are interested in having an external control installed, please consult your installing contractor.

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.
TROUBLESHOOTING
DIAGNOSTIC CODES
The on-board control will display a diagnostic code if an error should occur and service is required. Contact your installing contractor if E1– E7 or E9 is displayed on the on-board control screen. E8 will be displayed if the incoming air temperature is below 50°F, above 104°F, or when the dew point is below 40°F. When the incoming air is within the acceptable range, the dehumidifier will resume operation. If the error persists, contact your installing contractor.
