3.1.1. Setting the wall mounting fixture and piping positions
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.

3.1.2. Drilling the piping hole (Fig. 3-2)
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.
The hole should incline so that the outside opening is lower than the in-
side opening.
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.

3.1.3. Installing the wall mounting fixture

Since the indoor unit weighs near 10 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 unsymetrical way.
(If possible, secure the fixture at all the positions marked with a bold ar-
row.) (Fig. 3-3)
Warning:
If possible, secure the fixture at all positions indicated with a bold arrow.
Caution:
Fasten a thread to the hole.
The level can be easily obtained by hanging a weight from the string and aligning the
string with the mark.

3.2. Preparation for piping connection

Remove the vinyl band that holds the drain pipe.
Rear, right and lower piping (Fig. 3-4)
Bind the refrigerant pipes and drain pipe with vinyl tape at three or more
points. This will facilitate passing the pipes through the wall.

Left and left rear piping
- 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 wall mounting
fixture. (Fig. 3-5)
