Installation Instructions
A. Select the Indoor location:
• Do not allow any heat or steam near the unit.
• Select a location where there are no obstacles in
front of the unit.
• Make sure that condensate drainage can be
conveniently routed away.
• Do not install near a doorway.
• Ensure that the space around the left and right
of the unit is more than 4". The unit should be
installed as high on the wall as possible but allow
a minimum of 4" from the ceiling.
• Use a stud finder to locate and mark stud locations
for mounting and to prevent unnecessary damage
to the wall.
• Install in a location that is strong enough to
withstand the full weight and vibration of the unit.
• Leave enough space to allow access for routine
maintenance.
• Select a location that gives easy access to
removing and cleaning air filters.
• Install in a location that is 3 ft. or more away from
other electrical appliances, such as televisions and
audio devices.
C. Install the Tubing
• Measure and mark the location where the piping hole
is to be drilled.
• Follow these steps to move the drain pipe if the 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.

Step 2 - Installation of the Indoor Unit
Proper Installation for Drainage
Set the unit on mount or pad using team lift.
Do not install the drain elbow if the unit is
located in an area where freezing can occur.
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.
See Illustration on page 7.
• Knockouts are provided on the unit case for
Left, Right, and Right Below usage.
• 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.
