3 Unit specifications and features
White mist emerging from the indoor
unit
• A white mist may be generated due to a
large temperature difference between
air inlet and air outlet on COOL mode in
places with high relative humidity.
• A white mist may be generated due
to moisture created in the defrosting
process when the air conditioner
restarts in HEAT mode operation after
defrosting.
Noise coming from the air conditioner
• You may hear a low hissing sound
when the compressor is running or
has just stopped running. This sound
is the sound of the refrigerant flowing
or coming to a stop.
• You may also hear a low "squeaking"
sound when the compressor is running
or has just stopped running. This is
caused by tempera heat expansion
and cold contraction of the plastic
parts in the unit when the temperature
is changing.
• A noise may be heard due to the louver
restoring itself to its original position
when power is first turned on.
Dust blowing out from the indoor unit
This is happens when the air conditioner
has not been used for a long time or
during its first use.
Smell emitting from the indoor unit�
This is caused by the indoor unit giving
off smells permeated from building
materials, furniture, or smoke.

The air conditioner turns to FAN ONLY
mode from COOL or HEAT (for cooling
and heating models only) mode�
When the indoor temperature reaches the
set temperature setting, the compressor
will stop automatically, and the air
conditioner turns to FAN only mode. The
compressor will start again when the
indoor temperature rises on COOL mode
or falls on HEAT mode to the set point.
Droplets of water may form on the surface
of the indoor unit when cooling occurs in
relatively high humidity (defined as higher
than 80%). Adjust the horizontal louver to
the maximum air outlet position and select
HIGH fan speed.
Heating mode (For cooling and heating
models only)
The air conditioner draws in heat from the
outdoor unit and releases it via the indoor
unit during heating. When the outdoor
temperature falls, heat drawn in by the
air conditioner decreases accordingly.
At the same time, heat loading of
the air conditioner increases due to
larger difference between indoor and
outdoor temperature. If a comfortable
temperature cannot be achieved with the
air conditioner alone, it is recommended
that you use a supplementary heating
device. Lightning or a car wireless
telephone operating nearby may cause
the unit to malfunction. Disconnect the
unit from its power source and then re-
connect the unit with the power source
again. Push the ON/OFF button on the
remote controller to restart operations.
