Cause
The unit does not operate if it is turned on immediately after it is turned off. This is
to protect the unit. Please wait about 3 minutes.
• Some odours may be emitted from the indoor unit. This is the result of room
smells (such as furniture, tobacco, etc.) which have been taken into the unit.
• Consult authorised service centre for cleaning if the odours persist.
The swishing noise like water fl owing is the refrigerant fl owing inside the unit.
During cooling operation, a thin mist may be seen emitted from the indoor unit
due to high room temperature and humidity. After a period of time, the mist will
disappear as the decrease of room temperature and humidity.
This is the sound of friction caused by expansion and/or contraction of panel or
other parts due to the change of temperature.
• Is the power cut off?
• Is the power plug loose? (if applicable)
• Is the circuit protection device tripped off?
• Is voltage higher or lower? (tested by professionals)
• Is the TIMER correctly used?
• Are the batteries exhausted?
• Is the temperature setting appropriate?
• Is the air inlet/outlet blocked?
• Is the fi lter dirty?
• Is the door or window open?
• Is low fan speed set?
• Are there heat sources in the room?
• The humidity is high.
• Condensing water overfl ows.
• Drain hose is loose or obstructed.
• During cooling operation, water condensates around the pipes and
connection joints.
• During defrosting operation, thawed water fl ows out.
• During heating operation, water on the heat exchanger drips out.
• The noise emitted when the fan or compressor relay is switched on or off.
• When the defrosting operation is started or stopped, there is a sound of
refrigerant fl owing in the reverse direction.
• In HEAT mode, when the temperature of indoor heat exchanger is very low,
airfl ow is stopped in order to prevent cold air. (within 2 minutes)
• In 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 2-3 minutes.
• During defrosting operation, water or vapour may be emitted.
• In DEHUMIDIFY mode, the indoor fan will stop blowing air for 3-12 minutes in
order to avoid condensing water being vaporised again.
If the unit operates at high humidity for a long time, moisture may be generated on
air outlet grill and then drip off.
It is normal. The unit is in defrosting operation and heating will recommence soon.
