How to fix installation plate Drill a hole in the wall
The wall you select should be strong and solid enough to prevent
vibration
1. Mount the installation plate on the wall with four
type A screws. If mounting the unit on a concrete
wall, use anchor bolts.
Mount the installation plate horizontally by 
aligning the centerline using a level.
2. Measure the wall and mark the centerline. It is also
important to use caution concerning the location
of the installation plate-routing of the wiring to
power outlets is through the walls typically.
Drilling the hole through the wall for piping con-
nections must be done safely.
■ Drill the piping hole with a ø70mm (0.76") hole
core drill. Drill the piping hole at either the right or
the left with the hole slightly slanted to the out-
door side.
