Step 2 - Installation of the Indoor Unit (Cont.)
Installation Instructions
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 is
correct.
• Place the indoor unit on a solid work surface before making
electrical connections.
• To make the electrical connections for the indoor unit, both
the outer plastic and inner galvanized steel cover plate must
be removed.
• Raise the front cover to access the screws for removing
these covers.
• Route the 14/4 AWG stranded 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.
• Replace both cover plates and lower the front casing after
the terminal block wiring is completed.
E. Mount Indoor Unit to Mounting Plate
• Bundle the refrigerant piping, drain piping, and wiring
with tape and 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, pushing the unit up slightly, rotate the
lower part of the unit fully against the wall, then pull
down do the lower hooks engage the brackets. (see
illustration)
• Verify the unit is secured and flush to the wall.
• Indoor Unit installation is finished at this time.
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.

G. To Remove the Indoor Unit
• Slightly raise the entire unit.
• Pull the lower portion of the unit off the lower hooks and pull
slightly away from the wall.
• Lift the upper portion of the unit off the upper hooks.
C. Install the Tubing
• Always use new clean copper tubing. Never reuse tubing if
replacing an existing system.
• Measure and mark the location where the piping hole is to
be drilled.
• Follow these steps to move the drain pipe if pipe location
will be on the left side of the unit.
1. Remove the stopper in the left drain hole and knockout the
molded plug inside the port.
2. Transfer the corrugate drain hose from the right side to the
left side.
3. Insert stopper into right side drain port. Using soap as
a lubricant and a small screwdriver will allow for easier
seating of the stopper.
• Drill the lineset hole using a 2 1/4” hole saw. Angle the drill
with a downward pitch to the outside wall so that the outside
wall hole will be at least a ¼” lower than the inside hole.
This allows for proper drainage of condensate.
• Install the lineset hole flange at the hole opening on the
inside wall.
NOTE: The flange is prescored. It may be necessary to
modify the flange to fit properly behind the wall unit housing.
