Safety Precautions

Features of protector Inspection
Noise pollution
Operating condition
The protective device maybe trip and stop
the appliance in the cases listed below:
HEATING
o
Outdoor air temperature is over 24 c
COOLING
DRY
o
Room temperature is over 27 c
o
Room temperature is below 21 c
o
Room temperature is below 18 c
If the air conditioner runs in "COOLING" or
"DRY" mode with door or window opened
for a long time when relative humidity is above
85%, dew may drip down from the air outlet.
The protective device will work at
following cases:
Stopping the appliance and restarting it
at once or changing mode during
operation, you need to wait 3 minutes.
After using for a long time , the air
conditioner should be inspected on
the following items:
Overheat of the power supply cord
and plug or even a burned smell.
Abnormal operating sound or vibration.
Water leakage from indoor unit.
Metal cabinet electrified .
Stop the air conditioner if above trouble
occurs.
It is advisable to have a detail inspection
after using it for 5 years even if none of
the above occurs.
Install the air conditioner at a place
that can bear its weight in order to
operate more quietly.
Features of HEATING modeFeatures of HEATING mode
Preheat
It is hard to raise the room temperature when outdoor temperature is very low. Use the air
conditioner together with other heating appliance in this case.
Defrost
At the beginning of HEATING operation, the airflow from indoor unit is discharged 2-5
minutes later.
In HEATING operation the appliance will defrost (de-ice) automatically to raise efficiency.
This procedure usually lasts 2-10 minutes. During defrosting, fans stop operation.
After defrosting completes, it returns to "HEATING" mode automatically.
