PRINCIPLES OF 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 the evaporator coil that is 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, where it flows to a drain tube that routes it to the nearest floor drain or condensate
pump. After the moisture is removed, the air moves through the condenser coil where it is reheated before being discharged 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 dryness setting
when not running, and displays the measured humidity when running.
The UP and DOWN arrow buttons allow the dryness setting to be set
from 1 to 7. Use the ON/OFF button to turn the dehumidifier ON or OFF.
Set the control at 3 for initial operation. This setting and corresponding
dew point is recommended for preservation and preventing
condensation on floor joists. 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, increase the dryness level.
• Ifyouprefertheairtobelessdry, decrease the dryness level.
See Table1 for dryness settings and corresponding dew point (DP).
HOW DOES THE DEHUMIDIFIER WORk?
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.

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 home is
higher than the setting, the dehumidifier will dehumidify the air until the humidity level drops below the setting.
HIgH DEW POINT ALERT
If the dehumidifier measures the dew point of the air to be 4°F or more higher than the setting for 72 consecutive hours, the ALERT LIGHT will
turn on and the display will show “HI”. The dehumidifier will continue to operate as normal when the ALERT LIGHT is on. If the dew point falls
within 4°F of the setting, the ALERT LIGHT will turn off.
The dehumidifier measures the dew point of the air every five (5) minutes even if the dehumidifier is turned off (using the ON/OFF button) to
determine if there is a high dew point conditions. Should the dehumidifier be turned off, the default high dew point alert setting defaults to 56°F.

EXTERNAL CONTROL OPTIONS
Your Aprilaire dehumidifier can be controlled with the optional Aprilaire Model 76 remote control.
Install the Model 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 a remote control installed, please consult your installing contractor.

message, press the UP and DOWN arrows simultaneously for 3 seconds.
FilterCleaningProcedure
1. Turn the ON/OFF switch OFF.
2. Remove the filter access door from either side of the dehumidifier.
3. Slide the filter out of the dehumidifier.
4. Flush the filter with warm water and a mild detergent solution.
5. Shake off the excess water from the filter.
6. Replace the filter, making sure the filter is secured in both the top and bottom filter rails.
7. Replace the filter access door.

CAUTION
Do not use spray solvents or cleaners on or near the inlet side of the ventilator.
If desired, apply cleaner to a cloth and use to clean the cabinet.
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.

DIAgNOSTIC CODES
The on-board control will display a diagnostic code and the alert light will turn on if an error should
occur and service is required. Contact your installing contractor if E1– E7 or HI 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.
When using a Model 76 as a remote control, the Model 76 display will show the diagnostic codes
E1– E8. If there is a high dew point alert (HI), the Model 76 will display E0.
