3.2.2. Drilling the piping hole (Fig. 3-3)
► Use a core drill to make a hole of 75-80 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
inside opening.
► Insert a sleeve (with a 75 mm diameter and purchased locally) through the
hole.
Note:
The purpose of the hole's inclination is to promote drain flow.
3.2.3. Installing the wall mounting fixture (Fig. 3-4)
► Since the indoor unit weighs near 21 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.
► 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.)
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 ▲ as shown by the arrows.
