SETTING THE DESIRED HUMIDITY LEVEL
1. Plug in dehumidifier and turn on/off switch ON� See FIGURE 4�
2. Press the ON/OFF button to turn the dehumidifier control ON� The display will show the
current setting, and the dehumidifier blower will turn on to start sampling the air�
3. The
and
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 55%RH when first installed� Allow the dehumidifier to run until it reaches
the setting before deciding if you want to change the setting� See FIGURE 5�
• 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�
4. After three (3) minutes of sampling, the measured humidity will be compared to the setting:
a. If the humidity is above the setting, the dehumidifier compressor turns on and "AIR
SAMPLING" will be replaced by "DEHUMIDIFYING"� The compressor remains on until the
measured humidity falls 3% RH below the setting� See FIGURE 6�
b. If the measured humidity is below the setting, the blowers turn off and the display
returns to showing the RH setting�
5. The dehumidifier will sample again every 60 minutes, or at any time if the humidity setting
is lowered�
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�
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�
Energy Savings Tip #1: Adjust the humidity setting to be as high as is comfortable to
reduce dehumidifier run time� If it feels clammy or "smells musty", lower the humidity
setting� To save energy, turn the dehumidifier to OFF when you open your windows, just as
you would with air conditioning�
Energy Savings Tip #2: If vacating your home for an extended period in the summer, set
the RH at 55% and set your thermostat as high as you are comfortable setting it to in the
cooling mode� Consult with appropriate professionals regarding the highest temperature
that is safe for your pets or possessions� This will keep the humidity at a controlled level
while minimizing the amount of cooling energy used�
