Drilling the Piping Hole in the Wall

Follow all piping clearance recommendations.

1. Using a 2-17/32 inch hole core drill bit, drill a hole at either the right or left side of the wall

mounting, pre-chosen following installation guidelines and application needs.

• The slant of the hole must be 3/16" to 5/16" from level with the slant being upward on the

indoor unit side and downward on the outdoor unit side.

2. Finish off the newly drilled hole as shown with bushing and sleeve covering to prevent dam-

age to the insulation and piping.

Mounting the Installation Plate to Wall

Follow the procedure below and general best practices when mount-

ing the indoor unit's installation plate to a wall.

1. The wall mounted indoor unit is shipped with the installation plate

attached to its back. To remove, unscrew the one (1) screw that

holds the installation plate to the back of the indoor unit.

2. Align the centerline using a leveling tool. Measure the wall and

mark the centerline.

3. 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. If mounting the unit on a concrete wall, use

field-supplied anchor bolts.

4. Observe all rear piping clearances when drilling into the 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.

• 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.

Removing the Indoor Unit Bottom Panel

To access the indoor unit piping port connections, and to make the indoor unit installation

procedure easier, open the front panel, and remove the bottom panel removed first.

1. Fully open the front panel. The control panel can be accessed on the bottom right side

of the front of the indoor unit.

2. Pull the screw cap(s) at the bottom of the indoor unit.

3. Unscrew the five (5) screws (depending on the indoor unit model) at the bottom of the

chassis panel.

4. Remove the bottom panel, being careful not to scratch the main horizontal vane.

Set aside the bottom panel to re-install after all procedures are complete.
