GENERAL INSTALLATION GUIDELINES
Indoor Unit Mounting
1. The wall mounted indoor unit is shipped with the installation plate
attached to its back. To remove, Unscrew all screw / screws that
hold the installation plate to the back of the indoor unit. Number
of screws depends on the indoor unit model.
2. Confirm the location where the installation plate will be placed.
(Install the indoor unit on a strong, hard wall that can withstand
its weight.)
3. Align the centerline using a leveling tool. Measure the wall and
mark the centerline.
4. Attach the installation plate to the wall following the measure-
ments and marks. Use the type “A” screws that are factory-sup-
plied with the plate.
• Insert a screw into the center hole of the installation plate, and
tighten.
• Verify the installation plate is horizontal using a leveling tool.
• Tighten the remaining screws into the holes indicated on the
installation plate.
•
If the installation plate is not level, any condensate will not drain away

5. Observe all rear piping clearances when drilling into the wall.
Do not use nails and / or screws to attach indoor units to sheet rock, drywall, plasterboard,
tile, plywood, or similar materials without proper anchors. Indoor units must be securely, and
properly mounted / anchored. Improper installation will result in physical injury.
Do not use nails and / or screws to attach indoor units to sheet rock, drywall, plasterboard,

Mounting the Installation Plate to the Wall
Follow the procedure below and general best practices when mounting the indoor unit’s installation plate to a wall.
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.
Select location carefully. Unit must be anchored to a strong wall to prevent unnecessary vibration.
