OPERATING INSTRUCTIONS
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 blinking. The defrost control sequence is as follows:
When the unit operates in the cooling operation, drying operation, the ambient temperature sensor
•
senses the evaporator coil temperature is below -1°C, after the compressor will stop operating for 10
minutes or the coil temperature up to 7 °C, the unit restart to cool operating mode.
When the unit operates in the drying operation, once the coil temperature sensor senses the
•
temperature of the evaporator is below 40°C and the differential temperature between coil
temperature and room temperature is below 19°C after the compressor operation for 20 minutes, the
unit start defrosting for 5 minutes and the power indicator blinking.
OVERLOAD PROTECTION
In the event of a power loss, to protect the compressor there is a 3-minute delay until the compressor restarting.
DRAINAGE (Self- evaporating system)
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 drying operation and
high humidity conditions. The condensate water evaporates at the condenser and evacuated through the
exhaust hose.
For continuous operation or unattended operating in drying, please connect the attached drain hose to the
unit. Condensate water can be automatically flow into a bucket or drain by gravity.

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.
•
Switch off the unit before
operating.
Remove the plug of the water
outlet opening and keep it in safe
area.
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.
Straighten the hose to avoid a trap existing in the hose.
Remove the rubber
sealing plug.
