<Color: yellow>

: Beware of hot surface.

Warning:

Carefully read the labels affixed to the main unit.

1.1. Installation

s After you have read this manual, keep it and the Installation Manual in a

safe place for easy reference whenever a question arises. If the unit is going to be operated by another person, make sure that this manual is given to him or her.

Warning:

• The unit should not be installed by the user. Ask the dealer or an authorized company to install the unit. If the unit is installed improperly, water leakage, electric shock or fire may result.

• Use only accessories authorized by Mitsubishi Electric and ask your dealer or an authorized company to install them. If accessories are installed improperly, water leakage, electric shock or fire may result.

• Do not touch the unit. The unit surface can be hot.

• Do not install the unit where corrosive gas is generated.

• The Installation Manual details the suggested installation method. Any structural alteration necessary for installation must comply with local building code requirements.

•Never repair the unit or transfer it to another site by yourself. If repair is performed improperly, water leakage, electric shock or fire may result. If you need to have the unit repaired or moved, consult your dealer.

•Keep the electric parts away from water (washing water) etc.

• It might result in electric shock, catching fire or smoke. Note1: When washing the Heat Exchanger and Drain Pan, ensure the

Control Box, Motor and LEV remain dry, using a water proof covering.

Note2: Never drain the washing water for the Drain Pan and the Heat

Exchanger using the Drain Pump. Drain separately.

• The appliance is not intended for use by young children or infirm persons without supervision.

•Young children should be supervised to ensure that they do not play with the appliance.

• Do not use a leak detection additive.

1) Outdoor unit

Warning:

• The outdoor unit must be installed on a stable, level surface, in a place where there is no accumulation of snow, leaves or rubbish.

• Do not stand on, or place any items on the unit. You may fall down or the item may fall, causing injury.

Caution:

The outdoor unit should be installed in a location where air and noise emitted by the unit will not disturb the neighbours.

2) Indoor unit

Warning:

The indoor unit should be securely installed. If the unit is loosely mounted, it may fall, causing injury.

3) Remote controller

Warning:

The remote controller should be installed in such a way that children cannot play with it.

4) Drain hose

Caution:

Make sure that the drain hose is installed so that drainage can go ahead smoothly. Incorrect installation may result in water leakage, causing damage to furniture.

5) Power line, fuse or circuit breaker

Warning:

• Make sure that the unit is powered by a dedicated supply. Other appliances connected to the same supply could cause an overload.

• Make sure that there is a main power switch.

• Be sure to adhere to the unit’s voltage and fuse or circuit breaker ratings. Never use a piece of wire or a fuse with a higher rating than the one specified.

6) Grounding

Caution:

• The unit must be properly grounded. Never connect the grounding wire to a gas pipe, water pipe, lightning conductor or telephone grounding wire. If the unit is not grounded properly, electric shock may result.

• Check frequently that the ground wire from the outdoor unit is properly connected to both the unit’s ground terminal and the grounding electrode.

1.2. During operation

Caution:

• Do not use any sharp object to push the buttons, as this may damage the remote controller.

• Do not twist or tug on the remote controller cord as this may damage the remote controller and cause malfunction.

•Never remove the upper case of the remote controller. It is dangerous to remove the upper case of the remote controller and touch the printed circuit boards inside. Doing so can result in fire and failure.

•Never wipe the remote controller with benzene, thinner, chemical rags, etc. Doing so can result in discoloration and failure. To remove heavy stains, soak a cloth in neutral detergent mixed with water, wring it out thoroughly, wipe the stains off, and wipe again with a dry cloth.

•Never block or cover the indoor or outdoor unit’s intakes or outlets. Tall items of furniture underneath the indoor unit, or bulky items such as large boxes placed close to the outdoor unit will reduce the unit’s efficiency.

Warning:

• Do not splash water over the unit and do not touch the unit with wet hands. An electric shock may result.

• Do not spray combustible gas close to the unit. Fire may result.

• Do not place a gas heater or any other open-flame appliance where it will be exposed to the air discharged from the unit. Incomplete combustion may result.

Warning:

• Do not remove the front panel or the fan guard from the outdoor unit when it is running. You could be injured if you touch rotating, hot or highvoltage parts.

•Never insert fingers, sticks etc. into the intakes or outlets, otherwise injury may result, since the fan inside the unit rotates at high speed. Exercise particular care when children are present.

• If you detect odd smells, stop using the unit, turn off the power switch and consult your dealer. Otherwise, a breakdown, electric shock or fire may result.

• When you notice exceptionally abnormal noise or vibration, stop operation, turn off the power switch, and contact your dealer.

• Do not over-cool. The most suitable inside temperature is one that is within 5 °C of the outside temperature.

• Do not leave handicapped people or infants sitting or standing in the path of the airflow from the air-conditioner. This could cause health problems.

Caution:

• Do not direct the airflow at plants or caged pets.

•Ventilate the room frequently. If the unit is operated continuously in a closed room for a long period of time, the air will become stale.

In case of failure

Warning:

•Never remodel the air conditioner. Consult your dealer for any repair or service. Improper repair work can result in water leakage, electric shock, fire, etc.

• If the remote controller displays an error indication, the air conditioner does not run, or there is any abnormality, stop operation and contact your dealer. Leaving the unit as it is under such conditions can result in fire or failure.

• If the power breaker is frequently activated, get in touch with your dealer. Leaving it as it is can result in fire or failure.

• If the refrigeration gas blows out or leaks, stop the operation of the air conditioner, thoroughly ventilate the room, and contact your dealer. Leaving the unit as it is can result in accidents due to oxygen deficiency.

When the air conditioner is not to be used for a long time

• If the air conditioner is not to be used for a long time due to a seasonal change, etc., run it for 4 - 5 hours with the air blowing until the inside is completely dry. Failing to do so can result in the growth of unhygienic, unhealthy mold in scattered areas throughout the room.

• When it is not to be used for an extended time, keep the [power supply] turned OFF. If the power supply is kept on, several watts or several tens of watts will be wasted. Also, the accumulation of dust, etc., can result in fire.

•Keep the power switched ON for more than 12 hours before starting operation. Do not turn the power supply OFF during seasons of heavy use. Doing so can result in failure.

• When not operating the unit for a long time during the winter season, remove the water inside the water pipe to prevent freeze.
