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

1. Mount the installation plate on the wall with 

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.

2. 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.

• Drill the piping hole with a ø70mm hole core drill.

Drill the piping hole at either the right or the left with
the hole slightly slanted to the outdoor side.

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

1. Use the piping kit accessory or the pipes purchased

locally.

2. Measure the distance between the indoor and the

outdoor unit.

3. Cut the pipes a little longer than measured distance.

4. Cut the cable 1.5m longer than the pipe length.

1. Completely remove all burrs from the cut cross sec-

tion of pipe/tube.

2. Put the end of the copper tube/pipe in a downward

direction as you remove burrs in order to avoid drop-
ping burrs into the tubing.

• 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)

1. Firmly hold copper pipe in a die in the dimension

shown in the table below.

2. Carry out flaring work with the flaring tool.

1. Compare the flared work with the figure by.

2. If a flared section is defective, cut it off and do flaring

work again.

Preparing the indoor unit's piping and drain hose for installation through the wall.

1. Route the indoor tubing and the drain hose in the

direction of rear left or right

2. Tape the tubing, drain hose and the connecting cable.

Be sure that the drain hose is located at the lowest
side of the bundle. Locating at the upper side can
cause drain pan to overflow inside the unit.

3. Indoor unit installation

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

Press the lower left and right sides of the unit against
the installation plate until the hooks engage into their
slots(clicking sound).

1. Align the center of the pipes and sufficiently tighten

the flare nut by hand.

2. Tighten the flare nut with a wrench.

3. When extending the drain hose at the indoor unit,

install the drain pipe.

1. Overlap the connection pipe insulation material and

the indoor unit pipe insulation material. Bind them
together with vinyl tape so that there may be no gap.

2. Wrap the area which accommodates the rear piping

housing section with vinyl tape.

3. Bundle the piping and drain hose together by wrap-

ping them with vinyl tape for enough to cover where
they fit into the rear piping housing section.
