Remote controller

WHEN YOU THINK THAT TROUBLE HAS OCCURRED

In the following cases, stop using the air conditioner and consult your dealer.

• When water leaks or drips from the indoor unit.
• When the operation indicator lamp blinks.
• When the breaker trips frequently.
• The remote control signal is not received in a room where an electronic ON/OFF type fluorescent lamp (inverter-type fluorescent lamp, etc.) is used.
• Operation of the air conditioner interferes with radio or TV reception. An amplifier may be required for the affected device.
• When an abnormal sound is heard.
• When any refrigerant leakage is found.

WHEN THE AIR CONDITIONER IS NOT GOING TO BE USED FOR A LONG TIME

1. Operate by COOL mode with the highest temperature set or FAN mode for 3 to 4 hours. [See page 6]
   This dries the inside of the unit.
   Moisture in the air conditioner contributes to favorable conditions for growth of fungi, such as mold.
2. Press [OFF/ON] to stop the operation.
3. Turn off the breaker and/or disconnect the power supply plug.
4. Remove all batteries from the remote controller.

When using the air conditioner again:

1. Clean the air filter. [See page 12]
2. Check that the air inlet and outlet of the indoor and outdoor units are not blocked.
3. Check that the earth is connected correctly.
4. Refer to the "PREPARATION BEFORE OPERATION", and follow the instructions. [See page 5]

INSTALLATION PLACE AND ELECTRICAL WORK

Installation place

Avoid installing the air conditioner in the following places.

• Where there is much machine oil.
• Salty places such as the seaside.
• Where sulfide gas is generated such as hot spring, sewage, waste water.
• Where oil is splashed or where the area is filled with oily smoke (such as cooking areas and factories, in which the properties of plastic could be changed and damaged).
• Where there is high-frequency or wireless equipment.
• Where the air from the outdoor unit air outlet is blocked.
• Where the operation sound or air from the outdoor unit bothers the house next door.
• The mounting height of indoor unit 1.8 m to 2.3 m is recommended. If it is impossible, please consult your dealer.
• Do not operate the air conditioner during interior construction and finishing work, or while waxing the floor. Before operating the air conditioner, ventilate the room well after such work is performed. Otherwise, it may cause volatile elements to adhere inside the air conditioner, resulting in water leakage or scattering of dew.

The installation location of the outdoor unit should be at least 3 m away from the antennas for TV sets, radios, etc. In areas where the reception is weak, provide greater space between the outdoor unit and the antenna of the affected device if operation of the air conditioner interferes with radio or TV reception.

For the optimum efficiency and to extend the life time of using, the outdoor unit should be installed in a well-ventilated dry place.

To prevent the effects of a fluorescent lamp, keep as far apart as possible.
