3) Installing the mount board (the wall-fixing bracket) (Fig. 3-8)
in.(mm)
s Selection of the mounting location requires thorough consideration. If the
wall does not seem to be strong enough, reinforce it with boards or beams
before installation.
s The mount board (the wall-fixing bracket) must be secured at both ends and
at the centre, if possible. Never fix it at a single spot or in any nonsymmetrical
way.
(If possible, secure the fixture at all the positions indicated with a bold ar-
row.)
s If securing the mount board with bolts, use commercially available M10 or
W3/8 bolts (through bolts, anchor nuts, etc.).
• Make sure that the bolt tip does not protrude more that 5/8 in. (15 mm) from the
wall surface.
• Use at least two bolts for a concrete wall, and at least four bolts for a foamed
concrete wall.
s If securing the mount board with tapping screws, use the included acces-
sory screws ™ or commercially available screw that are 5/32 in. (4 mm) in
diameter and 1-3/8 in. (35 mm) or more in length.
• If securing the mount board to ferroconcrete, use concrete screws or commer-
cially available anchor plugs.
Warning:
If possible, secure the fixture at all positions indicated with a bold arrow.
Caution:
• The unit body must be mounted horizontally.
• Fasten at the holes marked with c c c c c as shown by the arrows.
1 Fasten a thread to the hole
2 The level can be easily obtained by hanging a weight from the string and aligning
the string with the mark.
3.3. When embedding pipes into the wall (Fig. 3-9)
• The pipes are on the bottom left.
• When the refrigerant pipe, drain pipes internal/external connection lines etc. are to
A
be embedded into the wall in advance, the extruding pipes etc, may have to be bent
and have their length modified to suit the unit.
• Use marking on the mount board (wall-fixing bracket) as a reference when adjust-
ing the length of the embedded cooling pipe.
• During construction, give the length of the extruding pipes etc some leeway.

3.4. Preparation for piping connection (Fig. 3-10)
Rear, right and lower piping
Bind the refrigerant pipes and drain pipe with vinyl tape at three or more points.
This will facilitate passing the pipes through the wall.
A Vinyl tape
Left and left-rear piping
1. For left-rear piping, pull the pipes out the hole to determine their correct length,
then bend them. The indoor unit should hang on the mount board.

2. Lift the indoor unit by hooking the supporting piece (attached to the mount board)
to the ribs on the back of the unit as shown.
When piping work etc. is complete, replace the supporting piece on the mount
board.
(If the unit is not fixed securely, vibration may occur during operation.)

3. If the flare pipe is to be embedded into the wall in advance:
• Determine the length of pipe to be embedded by marking on the mount board as
a reference.
