3.2. Installing the wall mounting fixture
3.2.1. Setting the wall mounting fixture and piping positions
(Fig. 3-2)
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.

Bottom left rear pipe hole (ø75-ø80 mm, 2-61/64~3-35/64 inch)
Bottom right rear pipe hole (ø75-ø80 mm, 2-61/64~3-35/64 inch)
Knockout hole for left rear hole (75 × 480)
Bolt hole (4-ø9 mm, 23/64 inch hole)
Center measurement hole (ø2.5 mm, 3/32 inch hole)
Tapping hole (75-ø5.1 mm, 13/64 inch hole)
Hole centre
Align the scale with the line.
Insert scale.
3.2.2. Drilling the piping hole (Fig. 3-3)
Use a core drill to make a hole of 75-80 mm, 2-61/64~3-5/32 inch 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
inside opening.
Insert a sleeve (with a 75 mm, 2-61/64 inch diameter and purchased
locally) through the hole.
Note:
The purpose of the hole’s inclination is to promote drain flow.

When the projection dimension of a curtain rail or the like from the wall exceeds 60 mm,
2/23/64 inch extra distance should be taken because the fan air current may create a short
cycle.
1800 mm, 70-7/8 inch or greater from the floor surface (for high location mounting)
108 mm, 4-1/4 inch or greater with left or rear left piping.
Minimum 7 mm, 9/32 inch.
