INSTALLATION INSTRUCTIONS
Step 2 - Installation of the Indoor Unit (Cont.)
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.
• If pipe location will be on the left side of the unit,
follow these steps to move the drain pipe.
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.
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.
• Rout 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.
• After the terminal block wiring is completed, replace
both cover plates and lower the front casing.

E. Mount Indoor Unit to Mounting Plate
• Bundle the refrigerant piping, drain piping, and wiring
with tape and carefully rout 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.
