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?

Are the remote control batteries weak?

If the remote control display appears weak, replace the batteries.

When the Air Conditioner is Not Used for an Extended Period of Time

1To dry the internal parts of the indoor unit, operate the unit for 2 - 3 hours using:-

2Turn off the power supply and unplug.

3Remove the remote control batteries.

Recommended Inspection

After used over several seasons, the unit will become dirty and thus decreases the unit’s performance. Depending on the operation conditions, a dirty unit may produce odour and dust may pollute dehumidification system. Therefore, a seasonal inspection is recommended in addition to regular cleaning. (Consult an authorized dealer).

HELPFUL INFORMATION

Auto Operation

Press the Auto

Operation Button

AUTO OFF/ON

Automatic Operation

If the remote control fails to function or has been misplaced, press the Auto Operation button to start the Automatic operation.

The Automatic operation will be activated immediately once the Auto operation button is pressed. However, temperature cannot be adjusted in this operation.

The power indicator on the indoor unit will blink until the operation mode is selected automatically.

To cancel this operation, press once more.

Timer Setting

When power failure occurs, the timer setting will be cancelled. Once power is resumed, reset the timer.

Thunder and Lightning

This air conditioner is equipped with a built-in surge protective device. However, in order to further protect your air conditioner from being damaged by abnormally strong lightning activity, you may switch off the main power supply and unplug from power socket.

Auto Restart Control

If power is resumed after a power failure, the operation will restart automatically after 3 - 4 minutes.

Operation will be restarted automatically under the previous operation mode and airflow direction when power is resumed as the operation is not stopped by the remote control.

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.
