1. THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR

SAFETY

More than 100 mm
(3.94 in.)

Open as a rule
More than 500 mm (19.69 in.)
if the front and both sides are
open

More than 100 mm (3.94 in.)
More than 200 mm (7.87 in.)
if there are obstacles to both
sides

Open as a rule
More than 500 mm
(19.69 in.) if the back,
both sides and top are
open

More than 350 mm (13.78 in.)

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 structural alternations necessary for the installation must comply with the local building code require-
ments.

 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 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 after
a long period and cause a leakage of refrigerant.

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 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.

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 de-
fective contact, defective insulation, exceeding 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 securely.

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.

• 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.
