5.2 DRAINAGE

There are two ways of removal collected water produced by the unit. A. Manual draining: Empty water tank by manual.

B. Continuous draining: Use gravity to drain condensate water by attaching a drain  hose.

5.2.1 EMPTYING THE WATER TANK

The water tank built in unit, will fill up and shut the unit down once it is full. It will run  again once you empty the water tank and installed properly.

⚫ When the tank is full, the unit will make a buzzing sound, and the “Water Full” light will turn on.

⚫ Clean the inside of the tank as well as the outside.

⚫ Replace the empty tank back into the unit.

⚫ Press the POWER button to resume operating.

⚫ If the Water Full light does not extinguish, check that the float is correctly in place.

5.2.2 CONTINUOUS DRAINING

For continuous operation or unattended dehumidification, please connect the attached drain hose to the unit. Condensate water can be automatically flow into a  bucket or drain by gravity.

⚫ Set the unit in a horizontal surface and stable position.

⚫ Switch off the unit before operating.

⚫ Securely and properly connect the drain hose and make sure it is not kinked and  clear of obstruction.

⚫ Place the outlet of hose over a drain or bucket and ensure that water could freely flow out of the unit.

Do not submerge the end of hose into water; otherwise, it can cause “Air Lock” in the  hose. drain-pipe

To avoid water spillage:

• As the negative pressure of condensate drain pan is large, tilt the drain hose  downward toward the floor. It is appropriate that the degree of inclination should  exceed 20 degrees.

Straighten the hose to avoid a trap existing in the hose.

6. MAINTENANCE

• CLEANING THE AIR FILTER (every two weeks)

Dust collects on the filter and restricts the airflow. The restricted airflow reduces  the efficiency of the system and if it becomes blocked it can cause damage to the  unit.

The air filter requires regular cleaning. The air filter is removable for easy cleaning.  Do not operate the unit without an air filter, or the evaporator may be contaminated.

1.Remove the filter frame and take off the filter.

2. Soak the strainer in warm water at about 40 degrees Celsius. Rinse gently with a  neutral detergent.

Use the vacuum cleaners brush to gently remove dust from the screen.

3.Put the filter back.

 7.TROUBLE SHOOTING

1. FUNCTIONING TEMP.

5°C ≤ Ambient Temp. ≤ 32°C

When the ambient temp is lower or higher than the functioning temp, the dehumidifier stops.

When 5°C ≤ Ambient temp. ≤ 16°C, the compressor automatically defrosts at intervals;  during defrosting, the compressor stops, and the fan keeps running.

2.BEFORE CALLING FOR SERVICE

8. DECOMMISSIONING

8.1 STORAGE

Long-term storage – If you will not be using the unit for an extended period (more  than a few weeks) it is best to clean the unit and dry it out completely. Please  store the unit per the following steps:

1. Press power button to switch off and unplug the unit.

2. Drain the remaining water from the unit.

3. Clean the filter and let the filter dry completely in a shaded area. 4. Collect the power cord at the water tank.

5. Re-install the filter at its position.

6. The unit must be kept in upright position when in storage.

7. Preserving the machine in ventilating, dry, non- corrosive gas and safe place  indoor.

ATTENTION:

The evaporator inside the machine has to be dried out before the unit is packed to  avoid component damage and molds. Unplug the unit and place it in a dry open area  for days to dry it out. Another way to dry the unit is to set the humidity point more  than 5% higher than the ambient humidity to force the fan to dry the evaporator for a  couple of hours.

8.2 DISPOSAL
