Instructions / Assembly

D. Install the Tubing:
• Drill holes where the pipe holes were originally
marked.
• 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.
• If not able to align all screw holes with studs, wall
anchors are supplied.
• 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 need to be routed
to and from the unit in one direction: right rear.
See Illustration on page 6.
• Knockouts are provided on the unit case for Right
usage.
• Determine the location of the wall hole based on
the position of the mounting plate. Refer to
Mounting Plate Dimensions on the next page to
help you determine the optimal position. Refer to
this figure wall hole diameter and install it at a
slight angle to facilitate drainage.

bend the piping away from the back of the unit
roughly 90 degrees.
• Based on the position of the wall hole, relative to
the mounting plate, determine the necessary
angle the piping will need to be bent to pass
through the wall hole when the unit is mounted to
the bracket.
• Grip the refrigerant piping at the base of the bend.
Then, slowly, and with even pressure, bend the
piping away from the back of the unit roughly 90
degrees. The piping should be sticking straight
out from behind the unit once completed.
NOTE: The flange is prescored. It may be
necessary to modify the flange to fit properly
behind the wall unit housing.
CAUTION: Be extremely careful not to dent or
damage the piping while bending it away from the
unit, as this could negatively affect the performance.
