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 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 once per 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. 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 76 Control can be mounted directly in the home for easy access to the humidity setting and measured humidity in the living
space. The Model 76 continuously measures the humidity level and will turn on the dehumidifier on-demand.
The Model 76 can also act as a remote control if the dehumidifier
is located where it is not easy or convenient to access. When the
dehumidifier is located in and dehumidifying a crawl space, sealed
attic, or basement, there is no need to have to crawl under the house
or trudge up and down the stairs to know that your dehumidifier is
working. The Model 76 can be installed where you spend most of your
time and making changes to the setting or seeing what the humidity
is in these areas can be done from the comfort and convenience of
where you live. Consult your installing contractor for more information
about the Model 76 Control.
