OPERATING THE UNIT
When using the unit
When first using the dehumidifier, operate the unit
continuously 24 hours.
This unit is designed to operate with a working
O O O O
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.
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.

Positioning the unit
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
O O
fall below 5 C(41 F). The coils can become covered with
O O
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.
Removing the collected water
1. Pull out the bucket a little.
2. Hold both sides of the bucket
with even strength, and pull it
out from the unit.
3. Pour the water out.
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
NOTE: When the continuous drain feature is
not being used, remove the drain hose from
the outlet.
Water can be automatically emptied into a
floor drain by attaching the unit with a water
hose(not included).
Cut the cover down from the back drain
hose outlet. Attach a drain hose(ID=13.5mm)
and lead it to the floor drain or a suitable
drainage facility(see Fig.7).
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.
Make sure the water hose is lower than the
drain hose outlet.
Select the desired humidity setting and fan
speed on the unit for continuous draining to
start.
3. Clean the air filter
Fig. 8
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.
Fig. 9
Fig. 10
The air filter behind the front grille should be
checked and cleaned at least every 30 days
or more often if necessary.
NOTE: DO NOT RINSE OR PUT THE FILTER
IN AN AUTOMATIC DISHWASHER.
To remove:
Grip the tab on the filter and pull it upward, then
pull it out as shown in Fig.8.
Clean the filter with warm, soapy water. Rinse and
let the filter dry before replacing it. Do not clean the
filter in a dishwasher.
To attach:
Insert the air filter into the unit from underside to
upside. See Fig.10.
CAUTION:
DO NOT operate the dehumidifier without a filter
because dirt and lint will clog it and reduce
performance.
