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.
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.
Note:
When operating the air conditioner in low outside
temperature, be sure to follow the instructions de-
scribed below.
• Never install the outdoor unit in a place where
its air inlet/outlet side may be exposed directly to
wind.
• To prevent exposure to wind, install the outdoor
unit with its air inlet side facing the wall.
• To prevent exposure to wind, it is recommended
to install a baffle board on the air outlet side of the
outdoor unit.
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 fac-
tories, 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 equip-
ment.
• 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.

*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 Use wires in conformity with design AS/NZS 5000.2.
*4 Never use pipes with thickness less than specified. The pressure resistance will be insufficient.
*5 Use a copper pipe or a copper-alloy seamless pipe.
*6 Be careful not to crush or bend the pipe during pipe bending.
*7 Refrigerant pipe bending radius must be 100 mm or more.
*8 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)
*9 Insulation material : Heat resisting foam plastic 0.045 specific gravity
*10 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.
CAUTION
(Could lead to serious injury in particular environments when operated incorrectly.)
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.
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.
n
Do not operate the air conditioner during inte-
rior 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.
WARNING
The unit should be installed in rooms which have
the floor space specified below.
AP20VG: 1.4
m² or larger
When the indoor unit is connected to the multi
type outdoor unit of R32 refrigerant, please con
-
sult your dealer about the floor space specified.
As for the details, please refer to the Installation
Service Manual for New Refrigerant System.
