Protection of the air conditioner
Compressor protection
The compressor cannot restart for 3 minutes after
it stops.
Anti-cold air (Cooling and heating
models only)
The unit is designed not to blow cold air on HEAT
mode, when the indoor heat exchanger is in
one of the following three situations and the set
temperature has not been reached.
•When heating has just started.
•During defrosting.
•Low temperature heating.
The indoor or outdoor fan stop running when
defrosting (Cooling and heating models only).
Defrosting (Cooling and heating models
only)
•Frost may be generated on the outdoor unit
during a heat cycle when outdoor temperature
is low and humidity is high resulting in lower
heating effciency in the air conditioner.
•Under these conditions, the air conditioner will
stop heating operations and start defrosting
automatically.
•The time to defrost may vary from 4 to 10
minutes, depending the outdoor temperature
and the amount of frost buildup on the outdoor
unit.
Auto-Restart (some models)
Incase ofpower failure,the systemwillimmediately
stop. When power returns, the Operation light on
the indoor unit will flash. To restart the unit, press
the ON/OFF button on the remote control. If the
system has an auto restart function, the unit will
restart using the same settings.
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.

19 / 124 EN
Multi Split Type Air Conditioner / User Manual
•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.
