OPERATING THE UNIT
Positioning the unit
A dehumidifier operating in a basement will have little or no effect in drying an adjacent enclosed
storage area, such as a closet, unless there is adequate circulation of air in and out of the area.
Do not use outdoors.
This dehumidifer is intended for indoor residential
applications only. This dehumidifier should not be used
for commercial or industrial applications.
Place the dehumidifier on a smooth, level floor strong
enough to support the unit with a full bucket of water.
Allow at least 20cm of air space on all sides of the unit
for good air circulation.
Place the unit in an area where the temperature will not
fall below 5 C(41 F). The coils can become covered with
frost at temperatures below 5 C(41 F), which may reduce
performance.
Place the unit away from the clothes dryer, heater or radiator.
Use the unit to prevent moisture damage anywhere books
or valuables are stored.
Use the dehumidifier in a basement to help prevent
moisture damage.
The dehumidifier must be operated in an enclosed
area to be most effective.
Close all doors, windows and other outside openings
to the room.

When using the unit
When first using the dehumidifier, operate the unit
continuously 24 hours.
This unit is designed to operate with a working
environment between 5 C/41 F and 35 C/95 F.
If the unit has been switched off and needs to be
switched on again quickly, allow approximately
three minutes for the correct operation to resume.
Do not connect the dehumidifier to a multiple socket
outlet, which is also being used for other electrical
appliances.
Select a suitable location, making sure you have easy
access to an electrical outlet.
Plug the unit into a electrical socket-outlet with earth
connection.
Make sure the Water bucket is correctly fitted otherwise
the unit will not operate properly.
NOTE:When the water in the bucket reaches to a certain
level,please be careful to move the machine to avoid it
falling down.

OPERATING THE UNIT
Removing the collected water
There are two ways to remove collected water.
1. Use the bucket
When the unit is off,if the bucket is full, the unit will
beep 8 times and the Full indicator light will flash, the
digital display shows P2.
When the unit is on,if the bucket is full, the compressor
turns off and the fan turns off after 30 seconds for drying
the water of the condenser, then the unit will beep 8
times and the Full indicator light will flash, the digital
display shows P2.
Slowly pull out the bucket. Grip the left and right
handles securely, and carefully pull out straight so
water does not spill. Do not put the tank on the floor
because the bottom of the bucket is uneven. Otherwise
the bucket will fall and cause the water to spill.
Throw away the water and replace the bucket. The
bucket must be in place and securely seated for the
dehumidifier to operate.
The machine will re-start when the bucket is restored
in its correct position.
NOTES:
When you remove the bucket, do not touch any parts
inside of the unit. Doing so may damage the product.
Be sure to push the bucket gently all the way into the
unit. Banging the bucket against anything or failing to
push it in securely may cause the unit not to operate.
When you remove the bucket,if there is some water in
the unit you must dry it .
2. Continuous draining
Water can be automatically emptied into a floor
drain by attaching the unit with a water hose
(Id 5/16,not included))with a female threaded
end (ID:M=1 ,not included).
Install the drain hose onto the adaptor A (See Fig.7,
placed in the bucket).
Remove the plastic cover from the back drain outlet of
the unit and set aside and remove bucket,then insert
the drain hose through the drain outlet of the unit and
securely press it into the connector on the front of the
unit.(See.Fig.9)
Tighten the adaptor A and the unit by using two screws
(placed in the bucket).
Install the female threaded end of the water hose into
the adaptor A.(See.Fig.10),then lead the water hose
to the floor drain or a suitable drainage facility.
Make sure the hose is secure so there are no leaks.
Direct the hose toward the drain,making sure that
there are no kinks that will stop the warter flowing.
Place the end of the hose into the drain and make sure
the end of the hose is level or down to let the water flow
smoothly.Do never let it up..
Place the bucket back in the unit and make sure
that it is located correctly.
Select the desired humidity setting and fan speed
on the unit for continuous draining to start..

Care and cleaning of the dehumidifier
Turn the dehumidifier off and remove the plug
from the wall outlet before cleaning.
1. Clean the Grille and Case
Use water and a mild detergent. Do not use bleach
or abrasives.
Do not splash water directly onto the main unit. Doing
so may cause an electrical shock, cause the insulation
to deteriorate, or cause the unit to rust.
The air intake and outlet grilles get soiled easily, so use
a vacuum attachment or brush to clean.
2. Clean the bucket
Every few weeks, clean the bucket to prevent growth of mold,
mildew and bacteria. Partially fill the bucket with clean water
and add a little mild detergent. Swish it around in the bucket,
empty and rinse.
NOTE: Do not use a dishwasher to clean the bucket.
After clean, the bucket must be in place and securely
seated for the dehumidifier to operate.
3. Clean the air filter
Remove the filter every two weeks based on normal
operating conditions.
Remove the filter from the top of the unit (See.Fig.11a),
or to remove the filter,remove Bucket then pull filter
downwards (See.Fig.11b).
Wash the filter with clean water then dry.
Re-install the filter,replace Bucket.
