Fixing Installation Plate

The wall you select should be strong and solid enough to prevent vibration

1.Mount the installation plate on the wall with

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 connections must be done safely.
