ENGLISH
B. Install the Mounting Plate
• Remove plastic bag, tape, and mounting plate from the
back of the indoor unit.
• Place the mounting plate on the wall in the desired
location taking into account the minimum clearances
necessary for proper operation.
• Using a level, verify that the mounting plate is
horizontal and mark the screw locations.
• Attach the mounting plate to the wall with the supplied
screws.
• Wall anchors are supplied if not able to align all screw
holes with studs.
• Be sure that the mounting plate has been attached
firmly and that applied weight is evenly distributed by
each screw. (At least one screw in wall stud, others
can use wall anchors.)
• The piping for the indoor unit may be routed to and
from the unit in one of several directions: left, left rear,
right, right rear, or right below.
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.
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.
• 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.
