Selecting The Installation Location - Mitsubishi Electric MSZ-AP15VG Notice D'installation

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
according 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
• 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 fol-
lowing unpacking to before use.
• Where easily drained.
• At a distance 1 m or more away from your TV and ra-
dio. 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.
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).
Note:
In rooms where inverter type fluorescent lamps are
used, the signal from the wireless remote controller
may not be received.

*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.
*5 Be careful not to crush or bend the pipe during pipe bending.
*6 Refrigerant pipe bending radius must be 100 mm or more.
*7 If pipe length exceeds 7 m, additional refrigerant (R32) charge is required. (No additional charge is required for pipe
length less than 7 m.)
Additional refrigerant = A × (pipe length (m) – 7)
*8 Insulation material : Heat resisting foam plastic 0.045 specific gravity
*9 Be sure to use the insulation of specified thickness. Excessive thickness may cause incorrect installation of the
indoor unit and insufficient thickness may cause dew drippage.
n Do not touch the air inlet or the aluminum fins
of the outdoor unit.
This could cause injury.
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.
OUTDOOR UNIT
• Where it is not exposed to strong wind. If the outdoor
unit is exposed to a wind during defrosting, the defrost-
ing time will be longer.
• Where airflow is good and dustless.
• Where rain or direct sunlight can be avoided as much
as possible.
• Where neighbours are not annoyed by operation
sound or hot (or cool) air.
• Where rigid wall or support is available to prevent the
increase of operation sound or vibration.
• Where there is no risk of combustible gas leakage.
• When installing the unit at a high level, be sure to
secure the unit legs.
• Where it is at least 3 m away from the antenna of
TV set or radio. Operation of the air conditioner may
interfere with radio or TV reception in areas where
reception is weak. An amplifier may be required for
the affected device.
• Install the unit horizontally.
• Please install it in an area not affected by snowfall or
blowing snow. In areas with heavy snow, please install
a canopy, a pedestal and/or some baffle boards.
Note:
It is advisable to make a piping loop near outdoor unit
so as to reduce vibration transmitted from there.
