1.1. Installation
X
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.
• 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.
• Ask an authorized technician to need the unit maintenance.
• Do not stand on the unit.
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.
