This manual only describes the installation of indoor unit.
When installing the outdoor unit, refer to the installation manual of outdoor unit.
1-2. SELECTING THE INSTALLATION LOCATION
INDOOR UNIT
• Where airow 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 amplier may be required
for the affected device.
•
In a place as far away as possible from uorescent 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 lter 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 oor 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 uorescent 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 ammable gas could leak.
• Where there is much machine oil.
• Where oil is splashed or where the area is lled 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 sulde 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.
1-3. SPECIFICATIONS
*1 Connect to the power switch which has a gap of 3 mm or more when open to inter-
rupt 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 specied. The pressure resistance will be
insufcient.
*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 Insulation material : Heat resisting foam plastic 0.045 specic gravity
*8 Be sure to use the insulation of specied thickness. Excessive thickness may cause
incorrect installation of the indoor unit and insufcient thickness may cause dew
drippage.

CAUTION
(Could lead to serious injury in particular environments when operated incorrectly.)
■ Install an earth leakage breaker depending on the
installation place.
If an earth leakage breaker is not installed, it could cause
electric shock.
■ 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.
■ Do not touch the air inlet or the aluminum ns of
the outdoor unit.
This could cause injury.
■ 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 re. Also, advise user to keep the area around the
unit clean.
■ Do not operate the air conditioner during interior
construction and nishing work, or while waxing
the oor.
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.
WARNING
This unit should be installed in rooms which exceed the oor space
specied in outdoor unit installation manual.
• Refer to outdoor unit installation manual.
