• A "Pishi-pishi" squeaking sound is heard when

the air conditioner is in operation or after the

stop of operation.

Expansion and contraction of resin parts caused by

temperature change makes this noise.

• Draining water or motor rotation sound after

the indoor unit stop.

This sound is heard when cooling operation stop,

the drain pump operates and then stop.

Wait approximately 5 minutes.

8. DUST FROM THE INDOOR UNITS

• Dust may blow out from the unit after starting

operation from long resting time.

Dust absorbed by the unit blows out.

9. THE INDOOR UNITS GIVE OFF ODOURS

• During operation

The unit absorbs the smell of rooms, furniture,

cigarettes, etc., and then emits them.

If odour is a concern, you can set to zero fan speed

when the indoor temperature reaches the set

temperature.

For details, contact your local dealer.

10. THE AIR CONDITIONER DOES NOT COOL

EFFECTIVEL V

• The air conditioner is operating in the PROGRAM 

DRY OPERATION.

This is because program dry mode operates so that 

the indoor temperature decreases as little as possible. 

Lower the indoor temperature using the COOLING 

OPERATION, and then use the PROGRAM DRY 

OPERATION.

(Refer to 

"CHARACTERISTICS OF THE PROGRAM 

DRY OPERATION" 

on page 5

8

.)

Read through characteristics of the COOLING 

OPERATION, characteristics of the HEATING 

OPERATION, and characteristics of the PROGRAM 

DRY OPERATION on page 58.

Read the operation manual that attached to the 

outdoor unit. 

10. TROUBLE SHOOTING

Please check before requesting a service. 

1. If the air conditioner does not operate at all.

• Check if fuse has blown.

Turn off the power supply.

Contact your local dealer.

• Check if the power circuit breaker is blown.

If the tab of power circuit breaker is in the OFF position,

turn the power on with the power circuit breaker switch.

If the tab of power circuit breaker is in the trip position

do not turn the power on with the power circuit breaker

switch.

Contact your local dealer.

ON 

Tab 

Trip position 

Power circuit breaker 

(Earth leakage breaker) 

• Check if there is a power failure.

Wait until power is restored. If power failure occurs

during operation, the air conditioner automatically

restarts immediately after the power supply recovers.

64

2. If the air conditioner stops after operating the

air conditioner.

• Check if the air inlet or outlet of outdoor or indoor unit is 

blocked by obstacles.

Remove the obstacle and make it well-ventilated.

The horizontal blades at the air outlet are closed while 

the indoor stops.

• Check if the air filter is clogged. Ask a qualified service 

person to clean the air filters.

decrease in the airflow volume of the air conditioner 

will result and the performance of the air conditioner will 

be degraded and power consumption will increase if the 

air filter is clogged with dust or dirt.

In addition, this may cause dew condensation at the air 

outlet.

(Refer to 

"8. MAINTENANCE" 

on page 6

0

.)

3. The air conditioner operates but it does not

sufficiently cool or heat.

• Check if the air inlet or outlet of outdoor or indoor unit is 

blocked by obstacles. Remove the obstacle and make it 

well-ventilated.

The horizontal blades at the air outlet are closed while 

the unit stops.

Obstacles decrease the fan speed, and cause 

performance decrease and breakage when discharged 

air is suctioned.

They cause a waste of electricity, increase operating 

noise, or that may stop the devices.

• Check if the air filter is clogged. Ask a qualified service 

person to clean the air filters.

A decrease in the airflow volume of the air conditioner 

will result and the performance of the air conditioner will 

be degraded and power consumption will increase if the 

air filter is clogged with dust or dirt.

In addition, this may cause dew condensation at the air 

outlet.

(Refer to 

"8. MAINTENANCE" 

on page6

0

.)

• Check if the set temperature is not proper.

Set to an appropriate temperature, fan speed, and 

discharge direction.

• Check if the FAN SPEED button is set to LOW SPEED. 

Set to an appropriate temperature, fan speed, and 

discharge direction.

• Check if the airflow direction is not proper.

Set to an appropriate temperature, fan speed, and 

discharge direction.

• Check if the doors or the windows are open.

Shut doors or windows to prevent wind from coming in.

• Check if the ventilation fan is in operation.
• Check if direct sunlight enters the room (when cooling). 

Use curtains or blinds.

• When there are too many inhabitants in the room

(when cooling).

• Check if the heat source of the room is excessive

{when cooling).

4. Operation was performed or stopped although the

ON/OFF button was not pressed.

• Are you sure that the ON/OFF timer operation is not

used?

Turn off the ON/OFF timer.

Please refer to operation manual attached to the

remote controller.

• Are you sure that any remote control device is not

connected?

Contact the central control room that directed the stop.

• Are you sure that the display for centralized control is

not lit?

Contact the central control room that directed the stop.
