Troubleshooting
Do not repair the air conditioner yourself. Incorrect repairs may cause electric shock or fire, so please contact an
authorized service center for professional repair. You can save time and repair fees by going over the troubleshooting
tips below.
Indoor unit is not delivering air
• In HEAT mode, when the temperature of
indoor heat exchanger is very low, the air will
stop blowing in order to prevent cool air from
entering the room. (Within 3 min)
• In HEAT mode, when the outdoor temperature
is low or there is high humidity, frost will form
on the outdoor heat exchanger, and the unit
will automatically begin to defrost. The indoor
unit will stop blowing air for 3-12 mins.
During the defrosting process, water or vapor
may be produced.
• In dehumidifying mode, sometimes the indoor
fan will stop to keep the water from vaporizing
again and the temperature from rising.

Water leakage in the room
Noise from indoor unit emitted.
Stop running and remove the plug.
• There is harsh sound during operation.
• There are terrible odors during operation.
• Water is leaking into the room.
• Air switch or protection switch often breaks.
• Water or other liquid spilled into unit.
• There is an abnormal heat in power supply
cord and power plug.
Immediately stop operating all units, remove the power
plug and contact the dealer in following situations.
• The sound of fan or compressor relay is
switching on or off.
• When the defrosting function starts or stops,
it will make noises. This is due to the refrige-
rant flowing in the reverse direction.
• The air humidity is on the high side.
• The condensated water over-flowed.
• The indoor unit’s drainage pipe is loos.
• If the unit is running in conditions with high
humidity for a long time, moisture will con-
densate on the air outlet grill and drip off.
