This product is a dehumidier. It controls relative humidi- ty by passing the air through the unit, forcing the excess moisture to condensate over the cooling elements. Contact with this cold surface causes the moisture in the air to con

dense. This condensed water then drains safely into the water tank. The dried air then passes through the conden- ser where it is slightly warmed and re-enters the room at a slightly elevated temperature. ► FIG. 1

3. Evaporator (cold refrigerated coil)

4. Moist saturated air

Excess moisture will travel throughout your home, in the same way that cooking smells waft to every room in the house. For this reason, the dehumidier should be posi- tioned, so that it can draw this moist air towards it from all over the home. Alternatively, if you have a serious problem in one area you can begin by positioning the dehumidier close to this area and later moving it to a more central point. When positioning the dehumidier, ensure that it is placed on a level surface and that there is a minimum of 10 cm (4”) of space on either side of the unit to allow for efcient airow. This dehumidier is tted with castors for extra mobility, if you move the unit, it should rst be switched off and the water tank emptied. We do not recommend the use of an extension lead, so please try to ensure that the unit is sufciently close to a xed mains socket. If it is necessary to use am extension lead, please ensure the diameter of the wires of the cable is at least 1 mm

When the dehumidier is in operation, outside doors and windows should be closed when necessary for most ef- cient use . ► ► 3. BEFORE USE CAUTION!

DRAINAGE While the water tank is full, the compressor will stop for self-protection and the water full indicator will turn into red. To move the water tank, pull it out squarely from the unit. After empting the water tank, place the water tank into spa- ce. Make sure it is properly positioned, in order for the ’wa- ter full’ sign to go out and your dehumidier is operating. Please note, in case, the water tank has not been positio- ned well, the water full indicator will turn into red. ► ► CONTINUOUS DRAINAGE When the dehumidier is operated at very high humidity levels, the water tank will require more frequent drainage. In this situation, it may be more convenient to set the unit up for continuous drainage with the following procedures:

1. Pull out the water tank (FIG. 5).

2. Connect the drain hole with water tube of inner diame

ter: 11 mm. The water tube is not supplied with the unit (FIG. 6).

3. Ensure the water will always drain away freely and the

tube will remain in right place. Note! In very cold weather conditions, precautions should be taken to prevent the wa

ter tube from freezing.

4. Put the water tank back to its position.

Use soft cloth to wipe the unit clean. Don’t ever use volatile chemicals, gasoline, detergents, chemically treated clothes, or other cleansing solutions. These all could possibly hurt the cabinet.

This dehumidier is equipped with 2 lters (FIG. 7):

Extract the lter holder, remove the active carbon lter. Use a vacuum cleaner or tap the lter lightly for easy clea- ning. If the lter is particularly dirty, use warm water with a small amount of a small amount of medium strength detergent. Make sure the lter is completely dry before replacing. Do not expose the lter to sunlight.

2. ACTIVE CARBON FITLER (for capturing the particles

of dust suspended in the air and preventing the produc- tion of bacteria.) The active carbon lter placed under the anti-dust lter is not washable. Its life span is variable and depends on the ambient conditions where the unit is used. The lter should be checked periodically and replaced if necessary. STORAGE If not use the unit for an extended period of time. Please: Turing the unit off, unplug and tidy AC cord. ► Completely empty the water tank and wipe it clean. ► Cover the unit and store where it will not receive direct sunlight. ► ► 8. TROUBLE SHOOTING THE UNIT DOES NOT OPERATE: ► Is the unit plugged in? ► Is the house electricity on? ► Is the room temperature below 5

C? If so, then it is out of the working range of the unit. ► Ensure the humidistat (or ON/OFF switch) is turned on. ► Check the water tank is positioned properly in the unit and it is not full. ► Make sure the air inlet and outlet are not obstructed. THE UNIT SEEMS TO DO NOTHING: ► Is the lter dusty, contaminated ? ► Is the air intake or outlet blocked up? ► Is the room humidity already quite low?en

THE UNIT SEEMS TO DO LITTLE: ► Are too many windows or doors open? ► Is there something in the room producing lots of humi- dity? THE UNIT IS TOO NOISY: ► Check whether the unit is sitting on a level surface. THE UNIT IS LEAKING: ► Make sure the unit is in good shape. ► If you are not using continuous drainage, make sure the rubber plug (at the bottom of the unit) is in its position.
