■

Be sure to read "THE FOLLOWING SHOULD BE ALWAYS 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.

■

After reading this instructions, be sure to keep it together with the owner's manual in a handy place on the
customer's site.

WARNING

: Could lead to death, serious injury, etc.

CAUTION

: Could lead to serious injury in particular environments when operated

incorrectly.

WARNING

Incorrect installation could cause injury due to fire,
electric shock, the unit falling or leakage of water.
Consult the dealer from whom you purchased the
unit or special installer.

Do not install it yourself (customer).

When installed in an insufficiently strong place,
the unit could fall causing injury.

Install the unit securely in a place which can bear
the weight of the unit.

Incorrect connection and fixing could cause fire.

Use the specified wires to connect the indoor and
outdoor units securely and attach the wires firmly
to the terminal board connecting sections so the
stress of the wires is not applied to the sections.

If the electrical part cover of the indoor unit and/or
the service panel of the outdoor unit are not
attached securely, it could result in a fire or
electric shock due to dust, water, etc.

Attach the electrical part cover to the indoor unit
and the service panel to the outdoor unit securely.

The use of defective parts could cause an injury
due to a fire, electric shock, the unit falling, etc.

Be sure to use the part provided or specified parts
for the installation work.

Check that the refrigerant gas does not leak after
installation is completed.

Incorrect installation could cause a personal
injury due to fire, electric shock, the unit falling
or leakage of water.

Perform the installation securely referring to the
installation instruction.

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.

Perform electrical work according to the installation
manual and be sure to use an exclusive circuit.

CAUTION

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

Perform the drainage/piping work according
to the installation instruction.

If gas leaks and accumulates in the area
surrounding the unit, it could cause an explosion.

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

■

For maximum product life and efficiency
this unit has been designed, in the heating
mode, to lock-out at outdoor temperatures
below 26-29degF.
At outdoor temperatures below 26-29degF.
another means of heating the conditioned
space must be provided.

INSTALLATION OF INDOOR, OUTDOOR UNIT

Read completely, then follow step by step.

Select the best location

Indoor unit

■

Do not have any heat or steam near the
unit.

■

Select a place where there are no
obstacles in front of the unit.

■

Make sure that condensation drainage
can be conveniently routed away.

■

Do not install near a doorway.

■

Ensure that the space around the left and
right of the unit is more than 30cm(11.8in).
The unit should be installed as high on the
wall as possible, allowing a minimum of
12cm(4.7in) from ceiling.

■

Use a stud finder to locate studs to
prevent unnecessary damage to the wall.

Outdoor unit

■

If an awning is built over the unit to
prevent direct sunlight or rain exposure,
make sure that heat radiation from the
condenser is not restricted.

■

Ensure that the space around the back and
sides is more than 10cm(3.9in). The front
of the unit should have more than
70cm(27.6in) of space.

■

Do not place animals and plants in the
path of the warm air.

■

Take the air conditioner weight into
account and select a place where noise
and vibration are minimum.

■ Select a place so that the warm air and

noise from the air conditioner do not
disturb neighbors.

■

Rooftop Installations:

If the outdoor unit is installed on a roof structure, be
sure to level the unit. Ensure the roof structure and
anchoring method are adequate for the unit location.
Consult local codes regarding rooftop mounting.
If the outdoor unit is installed on root structures or walls,
this may result in excessive noise and vibration, and
maybe also classed as non serviceable installation.

How to mount installation plate

The wall you select should be strong and solid
enough to prevent vibration

Mount the installation plate on the wall with
four type A screws. If mounting the unit on a
concrete wall, use anchor bolts.

■

Mount the installation plate horizontally by
aligning the centerline using a level.

Measure the wall and mark the centerline. It
is also important to use caution concerning
the location of the installation plate-routing of
the wiring to power outlets is through the
walls typically. Drilling the hole through the
wall for piping connections must be done
safely.

FLARING WORK AND CONNECTION OF PIPING

Flaring work

Main cause for gas leakage is due to defect in
flaring work. Carry out correct flaring work in the
following procedure.

Cut the pipes and the cable.

■

Use the piping kit accessory or the pipes
purchased locally.

■

Measure the distance between the indoor
and the outdoor unit.

■

Cut the pipes a little longer than measured
distance.

■

Cut the cable 1.5m(59.1in) longer than the
pipe length.

Burrs removal

■

Completely remove all burrs from the cut
cross section of pipe/tube.

■

Put the end of the copper tube/pipe in a
downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.

A

B

Putting nut on

■

Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube
having completed burr removal.
(not possible to put them on after flaring
work)

C

Flaring work

■

Carry out flaring work using flaring tool as shown
below.

Firmly hold copper pipe in a die in the dimension
shown in the table above.

D

Check

■

Compare the flared work with figure below.

■

If flare is noted to be defective, cut off the flared
section and do flaring work again.

CAUTION

When install, make sure
that the remaining parts
must be removed clearly
so as not to damage the
piping and drain hose,
especially power cord
and connecting cable.

Route the indoor tubing and the drain hose in
the direction of rear left.

Insert the connecting cable into the indoor unit
from the outdoor unit through the piping hole.

■ Do not connect the cable to the indoor unit.

■ Make a small loop with the cable for easy

connection later.

Indoor unit installation

■ Hook the indoor unit onto the upper portion of the

installation plate.(Engage the three hooks of the
rear top and rear lower of the indoor unit with the
upper edge and lower edge of the installation
plate.) Ensure that the hooks are properly seated
on the installation plate by moving it left and right.

D

NOTE: If the drain hose is routed inside the room,
insulate the hose with an insulation material* so that
dripping from "sweating"(condensation) will not damage
furniture or floors.

*Foamed polyethylene or equivalent is recommended.
