Dust can be cleaned from the Air Filter either with a vacuum cleaner, or by washing the filter in a solution of mild detergent
and warm water. If you wash the filter, be sure to allow it to dry thoroughly in a shady place before reinstalling.
If dirt is allowed to accumulate on the Air Filter, air flow will be reduced, operating efficiency lowers and noise increases.
During periods of normal use, the Air Filters should be cleaned every two weeks.

Operation Tips
Instructions relating to heating are applicable only to "HEAT & COOL TYPE"
Heating Performance
This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors.
As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating
perfomance is being produced, we recommend you use this air conditioner in conjunction with another kind of
heating appliance.
Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time
may be required after first starting the air conditioner until the room is heated.
Microcomputer-controlled Automatic Defrosting
When using the Heating mode under conditions of low outdoor air temperature high humidity, frost may form on the outdoor
unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic
Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly (for
about 7 to 15 minutes).

Troubleshooting
Followings are not problems
Sound of water flowing is not a problem.

During unit operation or at stop, a swishing or gurgling noise may be heard.
This noise is generated by refrigerant flowing in the system.

Sound of cracking is heard.

During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or shrinking because of
temperature changes.

Smell are generated.

This is because the system circulates smells from the interior air such as
the smell of cigarettes or the painting on the furniture.

During operation, white fog or steam
comes out from the indoor unit.

When unit is running at places like restaurant, etc. where dense edible oil
fumes always exist, this will happen.

In cooling operation, unit switches to
blowing operation.

To prevent frost from accumulating on indoor heat exchanger, unit will switch
to blowing operation for a while then resume cooling operation.

Unit will not restart after stop.

Though ON/OFF button is set to ON, the unit won't
resume cooling, dry or heating operation in 3 min
after it is stopped, this is because of
3-min-delay protection circuit.

Won't start?

Please wait 3 minutes

No outlet air or fan speed can't be changed
in dry mode.

Unit will reduce fan speed repeatedly and automatically if room temp. is
too low in dry operation.

In heating operation, water or steam
are blown out of outdoor unit.

This occurs when frost accumulated on the outdoor unit is removed (during
defrosting operation).

In heating operation, indoor fan won't stop
even if unit is stopped.

After unit stop, indoor fan will go on running until indoor unit cools down.

Before ask for services, please first check your unit against the following.
Air conditioner won't start.
Is power supply switch turned on?

Is city power supply normal?

Is leakage current breaker activated?

This is very dangerous, please
disconnect power supply immediately
and contact your dealer.

Power
failure?
Power supply switch is not set at ON.
Poor cooling or heating
Are operation control adjusted
correctly as specified?

Is air filter too dirty?

Proper
temp
Are horizontal louvers at up position
(in heating mode)?

Any doors or windows left open?

9

Are there any obstacles in inlet or
outlet grill?

Troubleshooting
Poor cooling
Is there any direct sunlight in the room?

If there are unexpected heat sources
in the room?

Too many people in the room?

Cold air blows out (in heating mode). Is air conditioner in standby condition in heating mode?
If your unit still can't work properly after above mentioned checks, or following problems occur, please stop it immediately
and contact your dealer.
Fuses or circuit breakers often blow out.
Water comes out in cooling/dry operation.
Operation is abnormal or sound is heard.
When failure happens,the fan of indoor unit stop running.
For indoor failure, only running LED of remote receiver will indicate,
For outdoor failure, timer LED and running LED will indicate .timer LED of remote receiver stands for ten's place, and
running LED stands for one's place. Timer LED will flash firstly, 2 seconds later, running LED will flash too.After that
finishes, 4 seconds later, they will flash in turns again. Flash times is the failure of outdoor + 20.
For example,failure code that outdoor is 2, so indoor unit should display 22. As a result, timer LED flashes twice firstly,
then running LED flashes twice,But when outdoor failure LED flash 20,the indoor unit will flash 42,it's a special.
