CRAWL SPACE DEHUMIDIFICATION
The AprilAire
®
Dehumidier controls the humidity level in your
crawl space. A powerful blower inside the dehumidier draws
air into the cabinet where it is ltered before having moisture
removed� A sealed refrigeration system removes moisture by
moving the air through a series of tubes and ns 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
dehumidier drain pan to a drain tube routed to the nearest
oor 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 crawl space� The air leaving the
dehumidier will be warmer and drier than the air entering the
dehumidier.
You can reduce the amount of humidity that enters the
home by closing windows, doors and replace ues 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
dehumidier is not designed to prevent window condensation
in winter� Use ventilation to lower indoor humidity levels in the
winter�
WARNING
The following precautions indicate a hazardous situation
that, if not avoided, could result in death or serious injury.
• Always disconnect electrical power before starting
installation or servicing to avoid electric shock.
• Always wear glasses/goggles and gloves when installing
the unit. Sharp edges may cause serious cuts. Use care
when cutting plenum openings and handling ductwork.
• Be sure to use caution when handling the unit. Dropping
the unit may cause personal injury or equipment
damage.
CAUTION
Be sure the installation, service and maintenance are
performed by a qualied service technician. Improper
installation may cause injury or property damage.
• This unit is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction
concerning use of the unit by a person responsible for
their safety.
• Be sure to supervise children to ensure that they do not
play with the unit.
• Be sure to replace a damaged supply cord. It must be
replaced by a special cord or assembly available from the
manufacturer or its service agent.
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.
