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.

Your dehumidifier is equipped with two features that protect against unwanted energy consumption. Defrost is a normal operating mode that helps
to prevent significant ice formation on the refrigeration system coil. The dehumidifier display will show “DEFROSTING” when operating in this mode.
This mode can occur when there is not enough air moving through the dehumidifier or if the temperature and/or humidity of the incoming air is too
low. The second protection feature is the E8 code. E8 on the dehumidifier display indicates that the air entering the dehumidifier is below 50°F or
above 104°F, or the dew point of the incoming air is below 40°F. There would be a significant reduction in dehumidifier efficiency if the dehumidifier
operated outside of these conditions. Low dew point conditions can be seen in some basements or crawl spaces and usually occur in the Winter and
Spring months. The dehumidifier continues to monitor the incoming air and when the conditions are within the operating range, E8 will be removed
from the display and dehumidification will begin as needed.
OPTIONAL – HEATING AND COOLING SYSTEM BLOWER OPERATION
Your installing contractor may have configured the dehumidifier to turn on the heating and cooling system blower when the dehumidifier turns on to
allow for improved circulation of the dry air.
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 home is
higher than the setting, the dehumidifier will dehumidify the air until the humidity level drops below the setting. Note: The dehumidifier will continue
to dehumidify until the humidity level is 3%RH below the setting.
