INSTALLATION OF INDOOR UNIT
Step 3
Installation of Mounting 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.

INSTALLATION OF INDOOR UNIT
Step 4
Drill Hole in Wall for Interconnecting Piping, Drain & Wiring
If indoor unit refrigerant piping is going to exit from the rear:
1. It is recommended that the refrigerant pipe flare connectors extend through the wall
to the outside. In some situations field-fabricated piping extensions will be required to
extend the indoor unit refrigerant flare connections to the outside of the wall.
2. Use mounting bracket diagrams and dimensions to find and mark the proper location
for the wall hole.
If refrigerant piping is going through the right or left side of front panel:
1. Use a small saw blade to carefully cut a U-shaped hole in the side of the front panel.
The hole must be large enough for refrigerant pipes, condensate hose and wires.
2. Determine and mark proper location for wall hole.
3. Use table below to determine recommended wall hole size for your unit size.

4. Cut the wall hole with a 5° to 10°
downward slant to the outdoors.
5. Insert a wall hole sleeve into hole to
prevent damage to refrigerant pipes,
insulation, condensate drain hose
and wiring.
6. Seal around wall hole sleeve with
caulk or foam to weatherproof.
