Selecting The Installation Location - Mitsubishi Electric MLZ-KP25VF Notice D'installation

I Install an earth leakage breaker depending on
the installation place.
If an earth leakage breaker is not installed, it could
cause electric shock.
I Perform the drainage/piping work securely ac-
cording to the installation manual.
If there is defect in the drainage/piping work, water
could drop from the unit, soaking and damaging
household goods.

1-2. SELECTING THE INSTALLATION LOCATION

INDOOR UNIT
WARNING
This unit should be installed in rooms which exceed the floor space
specified in outdoor unit installation manual.
• Refer to outdoor unit installation manual.
• Where airflow is not blocked.
• Where cool (or warm) air spreads over the entire room.
• Where it is not exposed to direct sunshine. Do not expose to direct sunshine
also during the period following unpacking to before use.
• Where easily drained.
• At a distance 1 m or more away from your TV and radio. Operation of the
air conditioner may interfere with radio or TV reception. An amplifier may
be required for the affected device.
• In a place as far away as possible from fluorescent and incandescent lights. In
order to make the infrared remote control operate the air conditioner normally.
The heat from the lights may cause deformation or the ultraviolet may cause
deterioration.
• Where the air filter can be removed and replaced easily.
• Where it is away from the other heat or steam source.

*1 Connect to the power switch which has a gap of 3 mm or more when open to
interrupt the source power phase. (When the power switch is shut off, it must
interrupt all phases.)
*2 Use wires in conformity with design 60245 IEC 57.
*3 Never use pipes with thickness less than specified. The pressure resistance will
be insufficient.
*4 Use a copper pipe or a copper-alloy seamless pipe.
CAUTION
I Do not touch the air inlet or the aluminum fins
of the outdoor unit.
This could cause injury.
I Do not install the outdoor unit where small ani-
mals may live.
If small animals enter and touch the electric parts
inside the unit, it could cause a malfunction, smoke
emission, or fire. Also, advise user to keep the area
around the unit clean.
Wire specifications *2
Frequency Indoor/outdoor connecting wire
50 Hz 4-core 1.5 mm
(Could lead to serious injury in particular environments when operated incorrectly.)
I 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.
REMOTE CONTROLLER
• Where it is easy to operate and easily visible.
• Where children cannot touch it.
• Select a position about 1.2 m above the floor and check that signals from
the remote controller are surely received by the indoor unit from that posi-
tion ('beep' or 'beep beep' receiving tone sounds). After that, attach remote
controller holder to a pillar or wall and install wireless remote controller.
Note:
In rooms where inverter type fluorescent lamps are used, the signal from the
wireless remote controller may not be received.
Note:
Avoid the following places for installation where air conditioner trouble is
liable to occur.
• Where flammable gas could leak.
• Where there is much machine oil.
• 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).
• Salty places such as the seaside.
• Where sulfide gas is generated such as hot spring, sewage, waste water.
• Where there is high-frequency or wireless equipment.
• Where there is emission of high levels of VOCs, including phthalate
compounds, formaldehyde, etc., which may cause chemical cracking.
• The appliance shall be stored so as to prevent mechanical damage from
occurring.

cause incorrect installation of the indoor unit and insufficient thickness may cause
dew drippage.
