Mitsubishi Electric MFZ-KT25VG Installation Manual page 3

n Install an earth leakage breaker depending on the
installation place.
If an earth leakage breaker is not installed, it could cause
electric shock.
n Perform the drainage/piping work securely accord-
ing to the installation manual.
If there is defect in the drainage/piping work, water could
drop from the unit, soaking and damaging household
goods.
n Do not touch the air inlet or the aluminum fins of
the outdoor unit.
This could cause injury.
1-2. SELECTING THE INSTALLATION LOCATION
This manual only describes the installation of indoor unit.
When installing the outdoor unit, refer to the installation manual of outdoor unit.
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.
• Rigid wall without vibration.
• 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.
• Do not install the unit in the environment where any gas equipment for propane,
butane or methane, sprays such as bug killer, equipment which generates smoke,
paint etc., and chemicals are used, or in the place where sulfur-based gas is
generated.
• The refrigerant sensor mounted in the indoor unit may react to them, and display
an error of refrigerant leakage. This may cause the unit not to operate.
If connect to the outdoor unit that uses R32 refrigerant, install in a room with a floor area of Amin or more, corresponding to refrigerant M (factory-charged refrigerant
+ locally add refrigerant). For refrigerant quantity and additional refrigerant charge, refer to the outdoor unit.

Refer to the installation manual of outdoor unit for refrigerant charge.
CAUTION
n Do not install the outdoor unit where small animals
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.
n 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 condi-
tioner, 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 position ('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 cook-
ing 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 oc-
curring.

(Could lead to serious injury in particular environments when operated incorrectly.)
n Do not install the unit in a place where smoke, gas,
or chemicals may fill.
The refrigerant sensor mounted in the indoor unit may
react to it, and display an error of refrigerant leakage.
n Be careful of the fan rotation when the breaker is ON.
When the refrigerant sensor detects the refrigerant
leakage, the fan starts rotating automatically. This may
cause injury.
n When using any aerosol sprays for interior con-
struction, finishing work, or sealing a wall hole,
turn off the breaker and ventilate the room well.
The refrigerant sensor may react to the gas in the
sprays, and it may cause misdetection.
