NOTICE
The following statements indicate a situation which
can cause damage to the equipment and personal
property, or cause the equipment to operate improperly.
• Do not use in pool applications. Pool chemicals can
damage the dehumidier.
• Do not use solvents or cleaners on or near the
circuit board. Chemicals can damage circuit board
components.
• Wait 24 hours before running the unit if it was not
shipped or stored in the upright position.
• Do not use dehumidication to prevent window
condensation in the winter. To address window
condensation, use ventilation to lower indoor humidity
in the winter.
WHOLE HOME DEHUMIDIFICATION
The AprilAire
®
Dehumidifier controls the humidity
level in your entire home. A powerful blower inside
the dehumidifier draws air into the cabinet where it
is filtered before having moisture removed. A sealed
refrigeration system removes moisture by moving
the air through a series of tubes and fins that are
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 to a drain tube routed to the nearest floor drain or
condensate pump. After the moisture is removed, the
air moves through a second coil where it is reheated
before being sent back into the home. The air leaving
the dehumidifier will be warmer and drier than the air
entering the dehumidifier.
You can reduce the amount of humidity that enters the
home by closing windows, doors and fireplace flues
when outdoor humidity is high, and by drying clothes
outside. Direct exhaust from kitchen vents and bath fans
is the best means of controlling humidity due to cooking
and showers/baths. The dehumidifier is not designed to
prevent window condensation in winter. Use ventilation
to lower indoor humidity levels in the winter.
OPERATING THE DEHUMIDIFIER
1. Use the ON/OFF Power Switch, located by the power
cord, to apply power to the dehumidifier.
OTE: N The ON/OFF Power Switch should stay ON unless the
unit will not be used for an extended period. Use the ON/
OFF Button on the control panel to turn the unit off for short
durations. With the ON/OFF Button in the ON position and
the dehumidifier idle (neither the fan nor the compressor
running) the unit will use less than 3W of power.
