The mounting wall should be strong and solid enough
to protect it from the vibration.

(if mounting the unit on the concrete wall, consider
using anchor bolts.)

• Always mount the Installation plate horizontally by

aligning the marking-off line by means of the
thread and a level.

• Line according to the arrows marked on lower the

left and the right side of the Installation Plate.
The meeting point of the extended line is the cen-
ter of the hole.

• Drill the Piping hole at either the right or the left

and the hole should be slightly slanted to the out-
door side.

• Use the accessory piping kit or the pipes pur-

chased locally.

• Measure the distance between the indoor and the

outdoor unit.

• Cut the pipes a little longer than measured dis-

tance.

• Cut the cable 1.5m longer than the length of the

pipe.

• Remove burrs from cut edges of pipes.

• Turn the pipe end toward down to avoid the metal

powder entering the pipe.

Caution:
If burrs are not removed, they may cause a gas leak-
age.

• Insert the flare nuts, mounted on the connection

ports of both indoor and outdoor unit, onto the
copper pipes. (When the flare nuts are removed
from the indoor unit.) Some gas may leak, as
some gas is charged to prevent the inside of the
pipe from rusting.

• Fit the copper pipe end into the Bar of flare tool

about 0~1.0mm higher. (See illustration)

• Flare the pipe ends.

evenly shine and be of even thickness.
After the flare part comes into contact with the connec-
tors, carefully check the flare finish.

Press the lower left and right side of the unit against
the Installation Plate until the hooks engage with their
slots (sound click).

• Make a small loop for easy connection later.

• 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 the hooks are properly seated on the
installation plate by moving it in left and right.

Take care to arrange the piping, drain hose and
cables as the feature 7 page for inserting it into the
indoor unit and mount the indoor unit on the instal-
lation plate.

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.
