AUTOMATIC DEFROST

At low room temperatures, frost may build up at the evaporator during operation. The unit will automatically start defrosting and the POWER LED will blink. The defrost control sequence is as follows: When the unit is operating in cooling or drying mode, and the evaporator coil temperature is below -1°C, the compressor will stop operating for 10 minutes until the coil temperature is up to 7°C – the unit will then restart to cool operating mode.

OVERLOAD PROTECTION

In the event of a power loss, to protect the compressor, there is a 3-minute delay until the compressor restarts.

DRAINAGE

The self-evaporating system uses the collected water to cool the condenser coils for better efficient performance.
There is no need to empty the drainage tank in cooling operation except in exceptionally high humidity conditions.
The condensate water evaporates at the condenser and is evacuated through the exhaust hose.
For continuous operation in drying mode, please connect the attached drain hose to the unit. Condensate water can then be directly drained into a bucket or similar.

Switch off the unit before this operation|
---|---
Remove the plug of the water outlet opening and keep it in a safe place
Securely and properly connect the drain hose and ensure it is not kinked and is clear of obstruction
Place the outlet of the hose over a drain or a bucket and ensure that water can flow freely out of the unit|
Do not submerge the end of the hose into water, as this can cause an “airlock” in the hose
To avoid water spillage, tilt the drain hose down towards the floor and straighten out any kinks in the hose
Note: Remember to replace the plug after using the drain hose!

CLEANING AND CARE

Cleaning the Air Filter
Dust collects on the air 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 the air filter or the evaporator may become contaminated.

1. Press the POWER button to switch off the unit, then unplug the unit from the mains
2. Remove the filter mesh from the back of the unit
3. Use a vacuum cleaner to suck dust from the filter
4. Turn the filter over and rinse the air filter under running water. Let the water run through the filter in the opposite direction of air flow. Set aside and allow the filter to air dry before reinstalling.

WARNING! To prevent accidental injury from extreme temperatures and sharp edges, do not touch the evaporator surface!

STORAGE

For long term storage (more than a few weeks) it is best to clean the unit and dry it out completely:

1. Unplug the unit and remove the exhaust hose and window kit.
2. Drain the remaining water from the unit
3. Clean the filter and let the filter dry completely
4. Collect the power cord at the water tank
5. Re-install the filter in its position
6. The unit must be kept in an upright position when in storage
7. To preserve the unit, keep it in a dry, well-ventilated space indoors.

Note: the evaporator has to be completely dried out to avoid component damage and mold. Unplug the unit and leave it in a dry open area for a few days to completely dry it out.
