1. THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR

SAFETY

• Be sure to read “THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY” before install-

ing 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 OPERATING INSTRUCTIONS in a

handy place on the customer’s site.

 WARNING

Do not install the unit 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 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, exceed-
ing the permissible current, etc.

Check that the refrigerant gas due not leak
after installation has completed.

If refrigerant gas leaks indoors, and comes into
contact with the fire of a fan heater, space heater,
stove, etc., harmful substances will be generated.

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 insufficient electrical work, it could re-
sult in a fire or an electric shock.

Attach the electrical cover to the indoor unit
and the service panel to the outdoor unit se-
curely.

If the electrical 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
due to a fire, an electric shock, the unit falling,
leakage of water, 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.

The appliance shall be installed in accordance
with national wiring regulations.

When installing or relocating the unit, make
sure that no substance other than the speci-
fied refrigerant (R410A) enters the refrigerant
circuit.

Any presence of foreign substance such as air
can cause abnormal pressure rise or an explo-
sion.

More than 100 mm

Open as a rule
More than 500 mm
if the front and both
sides are open

More than
100 mm
More than
200 mm if
there are
obstacles to
both sides

Open as a rule
More than 500 mm
if the back,
both sides and top
are open

More than 350 mm

Note:
The dimensions given along the arrows above are required to guarantee
the air conditioner’s performance. Install the unit in as wide a place as
possible for later service or repairs.

Before installation

This installation manual is only for the outdoor unit installation. In installing the indoor units, refer to the
installation manual attached to each indoor unit.
Any structual alternations necessary for the installation must comply with the local building code require-
ments.

 CAUTION

Perform earthing.

Do not connect the earth wire to a gas pipe, water
pipe, lightning rod or telephone earth wire. Defec-
tive earthing could cause an electric shock.

Do not install the unit in a place where an in-
flammable gas leaks.

If gas leak and accumulate in the area surround-
ing the unit, it could cause an explosion.

Fasten a flare nut with a torque wrench as
specified in this manual.

When fastened too tight, a flare nut may broken af-
ter a long period and cause a leakage of refrigerant.

Install a earth leakage breaker depending on
the installation place (Where it is humid).

If a earth leakage breaker is not installed, it could
cause an electric shock.

Perform the drainage/piping work securely
according to the installation manual.

If there is a defect in the drainage/piping work,
water could drop from the unit and household
goods could be wet and damaged.
