1-2. SELECTING THE INSTALLATION LOCATION
INDOOR UNIT
Where airflow is not blocked.
Where cool air spreads over the entire room.
On a rigid wall to reduce the possibility of vibration.
Where it is not exposed to direct sunlight.
Where it can be easily drained.
At a distance 3 ft. (1 m) or more away from a TV and
radio.
Operation
of the air conditioner may
interfere
with radio or TV
reception.
An
amplifier
may
be re-
quired for the affected device.
«
In a place as far away
as possible from fluorescent
and incandescent lights (so the infrared remote control
can operate the air conditioner normally).
«
Where the air filter can be removed and replaced easily.
Note:
Install the indoor unit high on the wall where air can dis-
tribute over the entire room.
REMOTE CONTROLLER
«
Where it is convenient to operate and easily visible.
«
Where children cannot easily touch it.
«
Select a position about 4 ft. (1.2 m) above the floor.
Check that signals from the remote controller from
that position are received by the indoor unit ('beep'
or 'beep beep' receiving tone sounds). Then, attach
remote controller holder to a pillar or wall and install
wireless remote controller.
1-3. SPECIFICATIONS
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 overly exposed to strong winds.
«
Where airflow is good and dustless.
«
Where
neighbours
are not annoyed
by operation
sound or hot 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.
If installing the unit in a location high above the ground,
be sure to secure the unit legs.
«
Where
it is at least 10 ft. (8 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
re-
ception
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 baffle boards.

Note:
*
It is advisable to make a piping loop near outdoor unit
so as to reduce vibration.
«
For increased
efficiency,
install the outdoor
unit in a
location where continuous direct sunlight or excessive
water can be avoided as much as possible.
Note:
When operating the air conditioner in low outside tem-
perature, be sure to follow the instructions described
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 and a baffle
board on the air outlet side.
Avoid the following places for installation where air
conditioner trouble is liable to occur.
«
Where flammable gas could leak.
«
Where there is an excessive amount of machine oil
in the air.
*
Salty places such as the seaside.
«
Where sulfide gas is generated such as a hot spring.
*
Where there is high-frequency or wireless equipment.
1-3-1. POWER
SUPPLY AND INDOOR/OUTDOOR WIRE
CONNECTION
*
Power should be taken from an exclusive branched circuit.
«
Wiring work should be based on applicable technical standards.
«
Wiring connections should be made following the diagram.
«
Securely tighten screws.
Connecting wires and the ground wire
«
Use solid conductor AWG14
or stranded conductor AWG14.
«
Use double insulated copper wire with 600 V insulation.
«
Use copper conductors only.
* Follow local electrical codes.
Power supply cable and ground wire
«
Use solid or stranded conductor AWG14.
