3.1. Installing the wall mounting fixture (Fig. 3-1)
1) Setting the wall mounting fixture and piping positions
s
Using the wall mounting fixture, determine the unit’s installation position
and the locations of the piping holes to be drilled.
Warning:
Before drilling a hole in the wall, you must consult the building contractor.

2) Drilling the piping hole (Fig. 3-2)
s
Use a core drill to make a hole of 90-100 mm diameter in the wall in the
piping direction, at the position shown in the diagram to the left.
s
The hole should incline so that the outside opening is lower than the inside
opening.
s
Insert a sleeve (with a 90 mm diameter and purchased locally) through the
hole.
Note:
The purpose of the hole’s inclination is to promote drain flow.

3) Installing the wall mounting fixture
s
Since the indoor unit weighs near 30 kg, 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. 3-3)
s
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. 3-4)
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.
3.2. 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. 3-5)
