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
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 typi-
cally. Drilling the hole through the wall for piping
connections must be done safely.
