GENERAL INSTALLATION GUIDELINES
Mounting of Indoor Unit Installation Plate
Follow the procedure and best practices below when mounting the
Wall-Mounted indoor unit’s plate to a wall.
Procedure
1. Before installation of the plate, confirm the position the screw
types (A or B) between chassis and installation plate.
2. Mount the installation plate horizontally by aligning the centerline
using a leveling tool.
3. Use provided screws when mounting the plating.
• If mounting the unit on concrete wall, use field supplied anchor
bolts.
4. Choose what side (left or right) to install the piping, and then
observe the left and right rear piping clearances when drilling into
the wall, as shown in Figures 9, 11, 12.
Select location carefully. Unit should be anchored to a strong wall to pre-
vent unnecessary vibration.
• When choosing a location for the wall mount plate, be sure to take
into consideration routing of wiring for power outlets within the wall.
Contacting wiring can cause serious bodily injury, or death.
• Use caution when drilling holes through the walls for the purposes
of piping connections. Power wiring can cause serious bodily injury,
or death.
