Installation Instructions
Step 2 - Installation of the Indoor Unit (Cont.)
D. Electrical Connections for the Indoor
Unit
NOTE: Be certain all wiring complies with local
building codes and NEC and that the supply voltage for
this system matches the unit nameplate.
• Place the indoor unit on a solid work surface before
making electrical connections.
• Both the outer plastic and inner galvanized steel
cover plates must be removed to make the electrical
connections for the indoor unit.
• Raise the front cover to access the screws for
removing these covers.
• Route the 14/4 AWG wiring through the slot in the
back of the unit and into the front access panel.
• Using a wire stripper, remove the insulation and
separate the 4 wires.
• Make wiring connections at each terminal according
to wiring diagram. Take note of the color of the wire
at each terminal and ensure the wires are connected
to the outdoor unit accordingly.
• Ensure each wire is under the screw terminal plate
and the plate is tightened.
• Ensure the 14/4 cable is secured under the strain
relief bracket.

E. Mount Indoor Unit to Mounting Plate
• Cap the refrigerant piping and bundle with drain
piping and wiring with tape. Carefully route the bundle
through the piping hole.
• With the top of the indoor unit closer to the wall, hang
the indoor unit on the upper hooks of the mounting
plate. Slide the unit slightly side to side to verify
proper placement.
• Rotate the lower portion of the indoor unit to the
mounting plate, and lower the unit onto the lower
hooks of the mounting plate. (see illustration)
• Verify the unit is secured and flush to the wall.

F. Condensate Drainage Pipe
• Verify the condensate drain line has a constant pitch
downward for proper water flow. There should be
no kinks or rises in the tubing which may cause a
trapping effect of the water (see illustration).
Optional: Can use PVC pipe by connecting a 1" ID
PVC pipe to the drain line coming out of the wall and
running to desired location.
