??? Pre-season Inspection

???Clean the air filters, re-insert and operate the air conditioners.

???Is the discharged air cold / warm?

Operation is normal if 15 minutes after the start of operation, the difference between the air intake and outlet vents temperature is:-

Cooling Model

COOL ???> 8??C or above

Heat Pump Model

COOL ???> 8??C or above

HEAT ???> 14??C or above

???Are the air intake or outlet vents of the indoor or outdoor units obstructed?

ENERGY SAVING AND OPERATION

HINTS

???Setting the Temperature

???Approximately 10% of electricity can be saved.

???Set the temperature higher or lower than the desired temperature.

Cooling Model

Cooling Operation : 1??C higher

Heat Pump Model

Cooling Operation : 1??C higher

Heating Operation : 2??C lower

???Air Filters

???Clean the air filters every 2 weeks.

???Dirty filters may reduces cooling or heating efficiency.

???Keep All Doors and Windows Closed

???Otherwise, cooling or heating performance will be reduced and electricity cost is wasted.

???Outdoor Unit

???Do not block the air outlet vents. Otherwise, it will lower the cooling or heating performance.

???Timer and Sleep Mode

???To prevent wastage of electricity, use sleep mode when sleeping or Timer when going out.

???Avoid Direct Sunlight

???Keep curtains or drapes closed to avoid direct sunlight during cooling operation.

TROUBLESHOOTING

??? Normal Operation

Is it okay?

???Air conditioner has been restarted, but does not operate for 3 minutes.

???A sound like water flowing can be heard.

???It seems that fog is coming out from the air conditioner.

???The room has a peculiar odour.

???The outdoor unit emits water or steam.

???During Automatic Airflow Volume setting, indoor fan stops occasionally.

???(For Heat Pump Model only)

Operation stops for about 12 minutes during heating (The power indicator blinks).

???(For Heat Pump Model only)

During heating operation, indoor fan may run at on and off conditions.

???Abnormal Operation

Is it okay?

???The air conditioner does not operate.

???Air conditioner produces loud noise during operation.

???The air conditioner does not cool or warm effectively.

???Remote control / display doesn???t work

This is the answer

??? This is to protect the air conditioner. Wait until the air conditioner begins to operate.

??? This is the sound of refrigerant flowing inside the air conditioner.

??? Condensation occurs when the airflow from the air conditioner cools the room.

??? This may be a damp smell emitted by the wall, carpet, furniture or clothing in the room.

??? In COOL/DRY operation, moisture in the air condenses into water on the cool surface of outdoor unit piping that causes dripping.

??? This is to remove the smell emitted by the surroundings.

??? This is to melt the frost which has accumulated on the outdoor unit (defrosting operating). This will take no longer than about 12 minutes. Water drips from the outdoor unit. Wait until this operation ends.

(the power indicator will light up). (Frost will accumulates on the outdoor unit when the outdoor temperature is low and humidity is high.)

??? This is to prevent undesired cooling effect during heating operation.

Please check

??? Has the circuit breaker been tripped?

???Has the power plug been removed from the wall outlet?

???Is the timer being used correctly?

??? Is the installation work slanted?

??? Has the temperature been set incorrectly?

???Are the filters dirty?

???Are the intake or outlet vents of the outdoor unit obstructed?

???Are all windows and doors closed?

??? Batteries empty?

??? Batteries correctly inserted (+) and (???)?

??? Call the Dealer Immediately

If the following conditions occur, turn off and unplug the main power supply, and then call the dealer immediately.

???Abnormal noise is heard during operation.

???Water or foreign material gets into the remote control by mistake.

???Water leak from the indoor unit.

???Switches or buttons do not operate properly.

???The circuit breaker switches off frequently.

???Power supply cord and plug become unusually warm.
