Precautions

To drain well make
sure the unit is
mounted horizontally
or tilted slightly to the
right as seen from
the front.

Do not embed the
unit in the wall.

When installing the
side panel, remove
the air filter (on the
right or left) and
make sure the lugs
are in the lug holes.
Then, push the side
panel until it fits
securely to the unit.

The indoor unit weighs up to 30kg including the bracket.

Before mounting the unit, make sure the wall is strong enough.

Installing Installation Bracket

Referring to the template, determine the location of the
indoor unit and cut the pipe hole as indicated.

When passing the refrigerant pipe through a wall in which a
lath is used, be sure to utilize pipe insulation.

In the case of a wooden wall (large wall):
(1) According to the distance between the indoor unit and the

ceiling, determine the vertical position (height) of the
installation bracket;

(2) Adjust the lateral position of the installation bracket with-

out changing the height so that each screw hole in the
bracket comes in the centre of a pillar or stud;

(3) In the case of a wooden wall, the distance between the

pillars is usually 900mm or 1,800mm (2,700mm) and with-
in this length, studs are located at intervals of 300 to
500mm. Be sure to install the bracket securely by driving
the accessory screws into the pillars and studs. At this
time, in order to prevent the indoor units from falling for-
ward, be sure to firmly fix the unit by tightening the screws
in the holes at both ends of the bracket (those indicated
by oblique lines on the template);

(Holes indicated by oblique lines on the template)

Wider side

(4) Make pilot holes before fitting screws.

In the case of a reinforced concrete wall:
(1) In the selected areas on the reinforced concrete wall, bore

holes at intervals of 480mm, and fit anchors;

(2) Attach the installation bracket to the wall by screwing bolts

or nuts into the anchors.
However, in the case where the hole anchors are used,
the depth of the holes should be adjusted so that the nut
heads extend no more than 15mm.

Precautions

There may be a wire conduit embedded in the wall. Check the
blue prints with the builder;

Make sure that the installation bracket is fitted securely before
mounting the indoor unit.

will sweat or cause a problem.

bending radius is 100mm or more.

Installation of Indoor Unit

(1) Pass the pipe through the pipe hole in

the wall and mount the indoor unit on
the upper end of the installation
bracket.

(2) Move the indoor unit to the right and

left checking to see that the upper end
of the bracket is fitted in the unit.

(3) Make sure the lower end of the

pipe-holding bracket hooks the lower
cabinet to prevent the indoor unit from
moving upward.

(1)  Remove the air filter and then remove the side panel.
(2)  Unfasten the right screw of the right end inlet grille.
(3)  Remove the two screws holding the side panel.
