Using the dehumidifier.
When first using the dehumidifier, operate the unit continuously 24 hours.
Moist, humid air is drawn over a cold refrigerated
dehumidifying coil. Moisture in the air condenses
on this coil and drains into a bucket (or through
a hose and drain).
Dry, clean air is drawn through the condenser
where it is heated and discharged out the top
grille into the room.
How the Dehumidifier Operates
It is normal that the surrounding air to become
slightly warmer as the dehumidifier operates.
When frost builds up on the evaporator coils, the
compressor will cycle off and the fan will continue
to run until the frost disappears.
In defrosting mode, fan motor normally run,
compressor stop running.

of the unit for good air circulation(The place with a
draught leaves the distance of the wall as 40 inches).
Place the dehumidifier in an area where the temper-
ature will not below 5°C. Or the coils can become
covered with frost,which may reduce performance.

is in operation or it has just stopped.
Otherwise it may cause some water to
drip from the draining pan.
The bucket must be in place and securely
seated for the dehumidifier to operate.

Use the bucket. When the bucket is removed,
the unit will shut off. Empty and replace the
bucket.
NOTE: Hold bucket with
both hands when emptying.
Important: Do not use the hose if using the
water tank to collect water. When the hose
is connected, water will be drained out through
it onto floor instead of into the tank.
NOTES:
Use a hose. Water can be automatically
emptied into a floor drain by attaching a
garden water hose (not included).
1. Remove the bucket from the front of the
unit.
2. Open the drain cover on the side of the
unit.
3. Thread a garden hose (not supplied) onto
the nozzle, cut to length, and lead it to the
floor drain.

ions and is directed downward. Press down drain
door so it rests on top of the hose.
Placing dehumidifier on an uneven surface or im-
proper hose installation may result in water filling
up the bucket and causing the unit to shut off.
