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 5C/41 F and 35C/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.

Pull out the bucket a little.
Hold both sides of the bucket with even strength, and pull it out from the unit.
Use the bucket
When the unit is off,if the bucket is full, the Full indicator light will light.
When the unit is on,if the bucket is full, the compressor and the fan turn off, and the Full indicator light will light, 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 bucket 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 right 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.
