3) How to fix installation plate
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 align-
ing the centerline using a level.

Weight
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 connections
must be done safely.
