Aprilaire COMPACT DEHUMIDIFIER 1730A - Manual (Page 2)

OPERATING INSTRUCTIONS
Begin by plugging in the dehumidifier and turning the On/Off switch ON.
DEHUMIDIFIER
CONTROL
The control will allow you to set the desired relative humidity (%RH)
level in your home and can be used to turn dehumidification On or Off.
Begin by pressing the ON button and ON will be displayed on the LCD
Screen (see LCD display in Figure 1). Use the arrow buttons to set the
control at 59% when first installed. Allow the dehumidifier to run until
the initial setpoint has been reached, before deciding if you want to
change the humidity setting.
Raise the setting if you prefer the air to be less dry; this will
reduce the amount of time that the dehumidifier runs.
Lower the setting if you prefer the air to be more dry; this
will increase the amount of time that the dehumidifier runs.
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 of
time when first installed.

Energy Savings Tip #1: Adjust the setting to be as high as is comfortable to reduce dehumidifier run time – if it feels clammy or smells
damp or moldy lower the setting. To save energy, turn the dehumidifier control 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 59% and set your thermostat to as
high as you are comfortable setting it 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 to help prevent mold while minimizing the amount of
cooling energy used.
