Warning:

Carefully read the labels a󰀩xed to the main unit.

Warning:

• These appliances are not accessible to the general public.

• The unit must 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 re may result.

• Do not stand on, or place any items on the unit.

• This air conditioner is NOT intended for use by children or inrm

persons without supervision.

• Young children must be supervised to ensure that they do not play with the air conditioner.

• When installing, relocating, or servicing the air conditioner,

use only the specied refrigerant written on the outdoor unit to

charge the refrigerant lines. Do not mix the refrigerant with any other refrigerant, and do not allow air to remain in the lines.

- If air is mixed with the refrigerant, then it may cause abnormal high

pressure in the refrigerant lines, resulting in an explosion and other hazards.

- The use of any refrigerant other than that specied for the

system will cause mechanical failure, system malfunction, or unit breakdown. In the worst case, this could lead to a serious impediment to securing product safety.

- It may also be in violation of applicable laws.

- MITSUBISHI ELECTRIC CORPORATION cannot be held

responsible for malfunctions or accidents resulting from the use of the wrong type of refrigerant.

• This indoor unit should be installed in a room which is equal

to or larger than the oor space specied in the outdoor unit

installation manual. Refer to the outdoor unit installation manual.

• Only use means recommended by the manufacturer to accelerate the defrosting process or to clean.

• This indoor unit shall be stored in a room that has no

continuously-operating ignition device such as open ame, gas

appliance, or electrical heater.

• Do not pierce a hole in or burn this indoor unit or refrigerant lines.

• Be aware that the refrigerant may be odour-free.

• 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-ame appliance

where it will be exposed to the air discharged from the unit. Incomplete combustion may result.

• 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 high-voltage parts.

• Never insert ngers, 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 o󰀨 the power

switch and consult your dealer. Otherwise, a breakdown, electric

shock or re may result.

• When you notice exceptionally abnormal noise or vibration, stop

operation, turn o󰀨 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 airow from the air-conditioner. This could

cause health problems.

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 re 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 o󰀨, 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 e󰀩ciency.

• Do not direct the airow 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 service. Improper repair work can result in water leakage,

electric shock, re, 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 re or failure.

• If the power breaker is frequently activated, get in touch with

your dealer. Leaving it as it is can result in re 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 deciency.

Disposing of the unit

Warning:

When you need to dispose of the unit, consult your dealer. If pipes

are removed incorrectly, refrigerant (uorocarbon gas) may blow

out and come into contact with your skin, causing injury. Releasing refrigerant into the atmosphere also damages the environment.

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 re.

• 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.
