INSTALLATION SITE INSTRUCTIONS

Step 1

Installation Site of Indoor Unit

Select a site that allows for the following:

• Ensure the installation complies with the installation minimum dimensions and meets the

minimum and maximum connecting piping length and maximum change in elevation.

•

Air inlet and outlet will be clear of obstructions, ensuring proper airflow throughout the room.

• Condensate can be easily and safely drained.

• All connections can be easily made to outdoor unit.

• Indoor unit is out of reach of children.

INSTALLATION OF INDOOR UNIT

Step 2

Installation of ounting Bracket

1. Attach the mounting bracket to the indoor unit.

2. Find the horizontal center of the indoor unit.

3. Mark the center of the indoor unit on mounting bracket for future reference.

NOTE: The center of the mounting bracket is not the center of the indoor unit.

4. Remove the mounting brackets from the indoor unit and position the mounting

bracket on the wall in desired location. Use centering mark on mounting bracket

for centering the indoor unit on the wall.

5. Mounting bracket must be installed horizontally and level right to left.

NOTE: Condensate drain pan has built-in pitch for proper drainage.

6. Secure mounting bracket to wall with a minimum of five screws, evenly spaced to

properly support indoor unit weight.

NOTE: It is recommended to install screw anchors for sheet rock, concrete block,

brick and such type of walls.
