Installation and Best Layout Practices
Mounting the Installation Plate
The mounting wall must be strong and solid enough to protect the unit from vibration.
Mount the installation plate on the wall using the Type “A” screws. If mounting the unit on con-
crete, consider using anchor bolts.
Always mount the installation plate horizontally. Measure the wall and mark the centerline using
thread and a level.
