environment that has a high relative humidity.
A white mist may generate due to moisture
generated from defrosting process when the air
conditioner restarts in HEAT mode operation after
defrosting.
You may hear a low hissing sound when the
compressor is running or has just stop running.
coming to a stop.
You also may hear a low “squeak” sound when
the compressor is running or just stopped
running. This is caused by heat expansion and
cold contraction of the plastic parts in the unit
when the temperature is changing.
A noise may be heard due to louver restoring to
its original position when power is furst turned on.
This is a normal condition when the air conditioner
of the unit.
This is caused by the indoor unit giving off smells
permeated from building material, furniture or
smoke.
When the indoor temperature reaches the setting
value, the compressor will stop automatically, and
the air conditioner turns to FAN mode.
The compressor will start again when the indoor
temperature rises in COOL mode or falls in HEAT
mode to the set point.
Condensate water is likely to form at the air outlet
if cooling or drying for a long time when the relative
humidity is more than 80% (with doors and windows
open).
Set the vertical louver to its maximum angle (to
windows.
Lighting or a car wireless telephone operating
nearby may cause the unit to malfunction.
Disconnect the unit with power and then re-connect
the unit with power again. Push ON/OFF button on
the remote control to restart operation.
The indoor unit may keep running after you switch
off the unit by pressing ON/OFF button.
Please check whether the X-Fan function is
switched off.
The following events may occur during normal
operation:
The compressor can’t restart for 3 minutes
after it stops
If the unit is operating in COOL mode and
in low ambient temperature, frost may be
formed on the heat exchanger. When indoor
heat exchanger temperature decreases
below 0°C, the compressor will stop
operation to protect the unit.
Frost may form on the outdoor unit in heating
operation when the outdoor temperature
is low but humidity is high, resulting in low
During this condition the air conditioner will
stop heating operation and start defrosting
automatically. The time to defrost may vary
from 3 to 12 minutes.
During defrosting, the fan motors of indoor
unit and outdoor unit will stop, the indoor
may emit vapor. This is not malfunction. After
will recover automatically.
In HEAT mode, the indoor fan will not operate
in order to prevent cold air being blown into
the room (within 5 minutes), if the indoor
heat exchanger does not reach a minimum
temperature under the following states:
(1) Heating operation just start.
(3) Heating at low temperature.
The indoor unit may blow gentle breeze and the
louver rotate to a certain position in the following
situation:
(1) In HEAT mode, the unit is turned on, the
compressor does not reach the starting
condition.
(2) In HEAT mode, the temperature reaches the
set value and the compressor stops running
for about 1 minute.
A white mist may generate due to a large
temperature difference between air inlet
and air outlet in COOL mode in an indoor
