3) Installing the wall mounting fixture
► Since the indoor unit weighs near 30 kg, selection of the mounting loca
-
tion requires thorough consideration. If the wall does not seem to be
strong enough, reinforce it with boards or beams before installation.
► The mounting fixture must be secured at both ends and at the centre, if
possible. Never fix it at a single spot or in any nonsymetrical way.
(If possible, secure the fixture at all the positions marked with a bold ar
-
row.) (Fig. 3-4)
► Secure the wall mounting fixture through its middle row of 12-mm-dia.
holes using locally purchased bolts (through bolts, bolt anchor and nut
anchor) of M10 or W3/8 threading. The bolt tip must not protrude by more
than 15 mm from the wall surface. (Fig. 3-5)
Use at least two bolts for a concrete wall, and at least four bolts for a
foamed concrete wall.

Warning:
If possible, secure the fixture at all the positions marked with a bold arrow.
Caution:
The unit body must be mounted horizontally.
3.3. Preparation for piping connection
Remove the vinyl band that holds the drain piping.
• This vinyl band can be used to temporarily attach the pipes to the wall mounting
fixture while connecting the left pipe.
1) Rear, right and lower piping (Fig. 3-6)
Remove the right side panel.
2) Left and left rear piping
Remove the right side panel.
When embedding pipes into the wall
(Fig. 3-7)
When the refrigerant pipe, drain pipes, internal/external connection lines, etc., are
to be embedded into the wall in advance, the extruding pipes, etc., may have to be
bent and have their length modified to the unit.
• Make the pipes to be embedded slightly longer than necessary, and install.

Remove the five screws indicated by the arrows in the diagram. (Fig. 3-8)
Remove the left side panel, then the lower panel.
• While pushing up the front lower portion of the side panel (to disengage the side
panel catch from the unit catch), slide the upper portion of the side panel to the
left.
• When the indoor unit is already mounted, be sure the unit does not fall from the
wall mounting fixture.
• For reassembly, put the catch at the front lower portion of the left side panel over
the unit body and push it to the right.
