Problem
• D uring cooling operation, water
condensates around the pipes and
connection joints.
• D uring defrosting operation, thawed
water flows out.
• D uring heating operation, water on the
heat exchanger drips out.
• T he noise emitted when the fan or
compressor relay is switched on or off.
• W hen the defrosting operation
is started or stopped, there is a
sound of refrigerant flowing in the
reverse direction.
• I n HEAT mode, when the temperature
of indoor heat exchanger is very low,
air flow is stopped in order to prevent
cold air. (within 2 minutes)
• I n HEAT mode, when the outdoor
temperature is low or humidity is high,
frost will be formed on the outdoor
heat exchanger. The unit will defrost
automatically and indoor unit will stop
blowing air for 3-12 minutes.
• D uring defrosting operation, water or
vapour may be emitted.
• I n Dehumidify mode, the indoor fan will stop
blowing air for 3-12 minutes in order
to avoid condensing water being
vaporised again.
• I f the unit operates at high humidity for a
long time, moisture will be generated on
the air outlet grill and then drip off.
