3.2.3. Installing the wall mounting fixture
s Since the indoor unit weighs near 30 kg, 66 lbs 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 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 arrow.)
(Fig. 3-4)
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 L 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. 3-5)
• The pipes are on the bottom left.
• When the cooling 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 suit the unit.
• Use marking on the mount board as a reference when adjusting the length of the
embedded cooling pipe.
• During construction, give the length of the extruding pipes etc some leeway.

3.4. Preparing the indoor unit
Rear, right and lower piping (Fig. 3-6)
1. Bind the cooling pipe and drain pipe together.
• Bind the pipes together with vinyl tape at three or more points. This will facilitate
passing the pipes through the wall.
2. Remove the corner box and knock out the knockout holes as necessary.
• Remove the corner box by pushing in a downward direction b, while at the same
time, pressing in the upper side part of the corner box a.
