1. THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR
SAFETY
■
Do not install it by yourself (customer).
Incomplete installation could cause injury due to
fire, electric shock, the unit falling or leakage of
water. Consult the dealer from whom you pur-
chased the unit or special installer.
■
Install the unit securely in a place which can
bear the weight of the unit.
When installed in an insufficient strong place, the
unit could fall causing injury.
■
Use the specified wires to connect the indoor
and outdoor units securely and attach the
wires firmly to the terminal block connecting
sections so the stress of the wires is not ap-
plied to the sections.
Incomplete connecting and fixing could cause a
fire.
■
Do not use intermediate connection of the
power cord or the extension cord and do not
connect many devices to one AC outlet.
It could cause a fire or an electric shock due to
defective contact, defective insulation, exceeding
the permissible current, etc.
■
Check that the refrigerant gas does not leak
after installation has completed.
■
Perform the installation securely referring to
the installation manual.
Incomplete installation could cause a personal
injury due to fire, electric shock, the unit falling or
leakage of water.
■
Perform electrical work according to the in-
stallation manual and be sure to use an ex-
clusive circuit.
If the capacity of the power circuit is insufficient
or there is incomplete electrical work, it could
result in a fire or an electric shock.
■
Attach the electrical part cover to the indoor
unit and the service panel to the outdoor unit
securely.
If the electrical part cover in the indoor unit and/
or the service panel in the outdoor unit are not
attached securely, it could result in a fire or an
electric shock due to dust, water, etc.
■
Be sure to use the part provided or specified
parts for the installation work.
The use of defective parts could cause an injury
or leakage of water due to a fire, an electric shock,
the unit falling, etc.
■
Be sure to cut off the main power in case of
setting up the indoor electronic control P.C.
board or wiring works.
It could cause an electric shock.
Caution
■
Perform grounding.
Do not connect the ground wire to a gas pipe, water
pipe, lightning rod or telephone ground wire. De-
fective grounding could cause an electric shock.
■
Do not install the unit in a place where an in-
flammable gas leaks.
If gas leaks and accumulates in the area sur-
rounding the unit, it could cause an explosion.
■
Install a ground leakage breaker depending
on the installation place (where it is humid).
If a ground leakage breaker is not installed, it
could cause an electric shock.
■
Perform the drain/piping work securely ac-
cording to the installation manual.
If there is a defect in the drain/piping work, water
could drop from the unit and household goods
could be wet and damaged.
• Please provide an exclusive circuit for the air conditioner and do not connect other electrical appliances to it.
Please report to your supply authority or obtain their consent before connecting this equipment to
the power supply system.
• Be sure to read “THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY” before installing
the air conditioner.
• Be sure to observe the cautions specified here as they include important items related to safety.
• The indications and meanings are as follows.
Warning: Could lead to death, serious injury, etc.
Caution: Could lead to serious injury in particular environments when operated incorrectly.
• After reading this manual, be sure to keep it together with the instruction manual in a handy place on
the customer’s site.
Warning
2. SELECTING THE INSTALLATION LOCATION
2-1
INDOOR UNIT
• Where airflow is not blocked.
• Where cool air spreads over the entire room.
• Rigid wall or ceiling without vibration.
• Where it is not exposed to direct sunshine.
• Where easily drained.
• At a distance 1 m or more away from your TV and radio (to prevent picture from being distorted or noise from
being generated).
• In a distance as far 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.
2-2
WIRELESS REMOTE CONTROLLER MOUNTING
• Place of mounting
- Where it is easy to operate and easily visible.
- Where children cannot touch.
• Mounting
Select a position about 1.2 m above the floor, check that signals from the controller are surely received by
the indoor unit from that position (‘beep’ or ‘beep-beep’ receiving tone sounds), attach remote controller
mounting hardware
4
to a pillar or wall, then set the wireless remote controller
3
.
In rooms where inverter type fluorescent lamps are used, the signal from the wireless remote controller may
not be received.
2-3
OUTDOOR UNIT
• Where it is not exposed to strong wind.
• Where airflow is good and dustless.
• Where it is not exposed to rain and direct sunshine.
• Where neighbours are not annoyed by operation sound or hot
air.
• Where rigid wall or support is available to prevent the increase
of operational sound or vibration.
• Where there is no risk of combustible gas leakage.
• When installing the unit at a high level, be sure to fix the unit
legs.
• Where it is at least 3 m away from the antenna of TV set or
radio. (Otherwise, images would be disturbed or noise would
be generated.)
• Install the unit horizontally.
Caution:
Avoid the following places for installation where air condi-
tioner trouble is liable to occur.
• Where there is too much oil such as for machine or cook-
ing.
• Salty environment as seaside areas.
• Hot-spring areas.
• Where sulfide gas exists.
• Other special atmospheric areas.
