How A Dehumidifier Works - Honeywell DH70PW Owner's Manual

HOW A DEHUMIDIFIER WORKS

When the dehumidifier is switched ON, a fan pulls moisture-laden air into the dehumidifier where it
passes through dehumidifying coils inside the unit. These coils condense moisture from the air and
collect it in the water tank. The dry air is then exhausted from the dehumidifier. The air flows through the
air vents of the dehumidifier into the room as dry, warm air.
IMPORTANT: The dehumidifier is designed to operate between 41°F (5°C) and 89°F (32°C). The
dehumidifier's performance may be greatly reduced if room temperatures exceed this temperature
range.
SELECTING A LOCATION (IMPORTANT)
Before using the dehumidifier, place the unit UPRIGHT for at least
1 hour before use to allow the refrigerant to stabilize. If the unit
was tilted on its side or upside-down during transportation, set
the unit upright for 4 hours before use.
For optimal efficiency, the dehumidifier must be operated in an
enclosed area. Keep all doors, windows and other outside
entrances to the room closed.
Place the dehumidifier at least 12 inches (31cm) away from other
objects (e.g. curtains or furniture) that may restrict airflow from the
front or through the air vents of the unit.
The dehumidifier must be positioned on a level floor.
IMPORTANT: The effectiveness of the dehumidifier can be
influenced by different factors. One factor is the rate at which
new, moisture-laden air enters the room and the amount of air
circulating in and out of the area to be dehumidified. For example,
if a door to a basement is constantly opened, letting new,
moisture-laden air into the room, dehumidification will take longer
than if the door was kept closed. If the dehumidifier is in a room
with a storage closet or cabinets, it will have little or no effect in
drying the inside of the storage closet or cabinets unless there is
adequate circulation of air in and out of these places. To
dehumidify these places, open the storage door or cabinet doors
to allow air circulation. You may find that installing a second
dehumidifier may be required for larger enclosed areas.
