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.

1.1.Installation

ss

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

ss

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.

• 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.

• 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.

5) Power line, fuse or circuit breaker

Warning:

•

Make sure that the unit is powered by a dedicated line. Other
appliances connected to the same line 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. Safety Precautions

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 high-voltage 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 continu-

ously 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, 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.

1.3. Disposing of the unit

Warning:

When you need to dispose of the unit, consult your dealer. If pipes
are removed incorrectly, refrigerant (fluorocarbon gas) may blow
out and come into contact with your skin, causing injury. Releasing
refrigerant into the atmosphere also damages the environment.

■ When using the wireless remote controller, point it towards the receiver on the indoor unit.

■ If the remote controller is operated within approximately two minutes after power is supplied

to the indoor unit, the indoor unit may beep twice as the unit is performing the initial auto­matic check.

■ The indoor unit beeps to confirm that the signal transmitted from the remote controller has
been received. Signals can be received up to approximately 7 meters in a direct line from
the indoor unit in an area 45° to the left and right of the unit. However, illumination such as
fluorescent lights and strong light can affect the ability of the indoor unit to receive signals.

■ If the operation lamp near the receiver on the indoor unit is flashing, the unit needs to be
inspected. Consult your dealer for service.

■ Handle the remote controller carefully! Do not drop the remote controller or subject it to
strong shocks. In addition, do not get the remote controller wet or leave it in a location with
high humidity.

■ To avoid misplacing the remote controller, install the holder included with the remote con­troller on a wall and be sure to always place the remote controller in the holder after use.
