storage area, such as a closet, unless there is adequate circulation of air in and out of the area.  
Do not use outdoors.  
40cm or  
This dehumidifer is intended ofr indoor residential  
more  
applications only. This dehumidifier should not be used  
for commercial or industrial applications.

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.  
Air intake  
grille  
Place the unit in an area where the temperature will not  
falll delow 5 C(41 F). The coils can become covered with  
frost at temperatures below 5 C(41 F), which may reduce  
performance.  
20cm or more  
20cm or more  
20cm or more

Use the dehumidifier in a basement to help prevent  
moisture damage.  
Do not force casters to move over carpet,  
nor move the unit with water in the bucket.  
(The unit may tip over and spill water.)  
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 and 35 C.  
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.

CARE AND MAINTENANCE  
Removing the collected water  
1. Pull out the bucket a little.  
There are two ways to remove collected water.  
1. Use the bucket  
When the bucket is full, the unit will automatically stop  
running, and the Full indicator light will flash.  
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.  
Fig.5  
2. Hold both sides of the bucket  
with even strength, and pull it  
out from the unit.  
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.  
Fig.6  
2. Continuous draining  
3. Pour the water out.  
Water can be automatically emptied into a floor  
drain by attaching the unit with a water hose  
(not included).  
Remove the water bucket from the front of the unit, you will  
find a section of hose located above the bucket.  
Remove the rubber plug from the back of the unit and store  
it in a safe location(see Fig.8).  
Fig.7  
Insert the water hose through the hole in the back of the unit  
and securely press it onto the connector on the front of the  
unit(see Fig.9). Then lead the water hose to the floor drain or  
a suitable drainage facility.  
Remove the  
rubber plug  
Replace the bucket in the unit. The bucket must be in place and  
securely seated.  
Push the hose  
into the drain  
hole  
Fig.8  
NOTE: When the continuous drain feature is not being  
used, remove the drain hose from the connector and  
attach the back drain hole with the rubber plug shown  
in Fig.1.

CARE AND MAINTENANCE  
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  
Household  
Drain  
Use water and a mild detergent. Do not use bleach  
or abrasives.  
Cleaner  
No  
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  
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.  
Fig. A  
Fig. B  
To remove:  
Grip the tab on the filter and pull it out as shown  
in Fig.A.  
Clean the filter with warm, soapy water. Rinse and  
let the filter dry before replacing it. Do not clean the  
filter in a dishwasher.
