During operation, the air conditioner may
sometimes exhibit a sound of "clatter" or
"rumble". This is the common sound of
refrigerant flow but not a trouble.
This is caused by the thermal expansion
or cold shrinkage of plastics.
Sometimes there are smells in the air flow
from the indoor unit. This is caused by the
smell of cigarettes or paint coatings inside
the unit.
During COOL or DRY operation, the unit
may blow out a thin mist. This is the condensate water mist caused by sudden cooling of the indoor air blown out from the
indoor unit.
During COOL operation, it automatically
changes to FAN mode.
The system couldnt be re-started immediately
after turning off.The unit can't start?
In order to prevent frost accumulation on
the heat exchanger in the indoor unit,
sometimes it will automatically transfers
to FAN mode, but soon will return to
COOL mode.
This is due to the systems self-protection
function, which prevents it from restarting
in 3 min after stops.
Please wait
for 3 min.

Page 17
Troubleshooting
During DRY operation, there is no air
sent out or fan speed cant be changed.
In HEAT mode, the outdoor unit
generates water or steam.
This occurs during removal of the frost
(in defrosting operation) on the radiator
of outdoor unit.
Defrost operation
In HEAT mode, the indoor fan still
keeps running even the unit operation
stops.
After the unit stops, the indoor fan will
continue to run for a while to eliminate
residual heat.
Before asking for after-service to an authorized service center, please check your air
conditioner for the following items
Is power on/off switched on?
ON

When installing, do use the accessories or specified parts. If not using the parts specified by our
company, water leakage, electric shock, fire and refrigerant leakage will occur.
Do not lead the drainpipe to drain where the sulfur gas may be involved. Otherwise, the poisonous
gas will enter into the indoor.
During installation, if refrigerant leakage occurs, do the ventilation work immediately. As soon as
the refrigerant gas meets fire, poisonous gas will be produce. If the refrigerant gas enters into room
and meet the air blowing heater, heater or stove etc. fire source, the poisonous gas may be produced.
After installation, confirm there is no leakage of refrigerant.
Do not install the unit in a place where the combustible gas may be leaked. In any case the
combustible gas leaks and accumulated around the unit, fire accident will occur.
Do heat insulation work to the refrigerant gas pipes and liquid pipes to reach the purpose of heat
preservation. If the heat insulation measure is not sufficient, water generated by condensing dew
will drip leading to wet the floor and indoor articles.
!
Do grounding work.Do not connect the grounding wire to gas pipe,tap,lighting rod or telephone
line.Improper grounding will cause electric shock.
