Owner's Manual

Operate the air conditioner on Air circulation
mode (Refer to page 12) for 2 to 3 hours.
• This will dry out the internal mechanisms.
When air conditioner is not going to be
used for a long time.
When the air conditioner is to be used again.
Turn off the circuit breaker, and disconnect
the plug.
Remove the batteries from the remote
control.
Turn off the circuit breaker when the air conditioner
is not going to be used for a long time.
Dirt may collect and may cause a fire.
Clean the air filter and install it in the indoor
unit.
(Refer to page 18 for cleaning filters.)
Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
CAUTION
When the air conditioner is not going to be used for a long time.
Operation ranges
The table below indicates the temperature ranges the air conditioner can be operated within.
Mode
Cooling
Heating
Indoor temperature
18 °C~32 °C
16 °C~30 °C
* When the outdoor temperature drops below 0°C, heating capacity may drop slightly depending on the
operation condition.
Outdoor temperature
18 °C~48 °C
-5 °C~24 °C
There is noise or vibration.
A clicking sound can be
heard when the unit
starts or stops due to
movement of the
reversing valve.
These are normal symptoms. The noise will stop.
Creaking sound: The
plastic parts of the in
door unit creak when
they shrink or expand
due to sudden
temperature changes.
Flowing or Blowing
sound: This is the flow
of refrigerant through
the air conditioner.
The indoor unit gives
off an odor.
Odors (such as cigarette
smoke) may be absorbed
into the indoor unit and
discharged with airflow.
If the smell does not disappear, you need to
wash the filter. If this does not work, contact
the service center to clean your heat exchanger.
The air conditioner
does not emit warm air.
When Heating Mode
starts, the vane is almost
closed, and no air comes
out, even though the
outdoor unit is operating.
This symptom is normal. Please wait until the
unit has generated enough warm air to blow
through the indoor unit.
The outdoor unit is in
Defrosting Mode.
Outside temperature is
too low.
In Heating Mode, ice/frost is built up on the coils
when the outside temperature falls. This function
removes a layer of frost on the coil, and it should
finish in approximately 15 minutes.
The heating effect may not be sufficient.
Tak-tak noise from indoor
unit
Contraction or expa-
nsion of plastic com-
ponents due to chan-
ge in temperature
It is a natural phenomenon, and can only
be reduced but not overcome completely
