Installation
2. Grasping the top and bottom
flanges of the rear closure panel
as shown in Figure 12, the entire
panel is pulled out diagonally
from one side.
Step 2. Install drain kit in wall
sleeve.
Drain kits are available for indoor or
outdoor installation to help
condensate drain from either the
right or left side of the wall sleeve
externally, or from the bottom of the
sleeve internally.
Note: For installation procedures,
please refer to the Installation
Guide that accompanied the
accessory.
If you do not use the drain kit,
condensate will drain out of the rear
of the wall sleeve. The drain kit must
be installed before the outdoor grille
is installed.
Step 3. Install outdoor air
grille in wall sleeve.
An outdoor air grille directs airflow
for proper unit operation and to
protect the outdoor coil. Install the
grille before installing the chassis.
Outdoor air grille options are either a
stamped grille or an architectural
grille. When replacing an old chassis
with an existing grille, please check
with your HVAC representative to
determine if the new chassis can be
used with the old outdoor grille.
Using the wrong type outdoor grille
can decrease cooling or heating
capacity, increase energy usage, or
shorten compressor life.
Note: For installation procedures,
please refer to the Installation
Guide that accompanied the
accessory.

Step 4. Install wall sleeve in
wall opening.
For condensate to drain properly
inside the unit, the sleeve must be
installed properly:
• level from right to left
• with a slight downward pitch
from the indoor side to the
outdoor side
Note: If equipment is 230/208 volt,
verify the electrical receptacle
is located within 52 inches of
the sleeve’s right hand corner.
Do not use an extension cord.
Note: For installation procedures,
please refer to the Installation
Guide that accompanied the
accessory.
5. Install unit chassis in wall
sleeve.
WARNING
Fire Hazard!
Do not use an extension cord with
this unit. Doing so may cause a fire.
1. Attach the insulation strip to the
upper rear of the wall sleeve. See
Tabl e 13. If using an extended
wall sleeve, attach the insulation
strip between the two baffles,
touching the baffle surface facing
towards the front.
2. Remove the cabinet front from
the chassis by pulling the bottom
of the cabinet front away from
the chassis until the retaining
clips disengage.
3. If using a subbase, be sure the
right-hand subbase cover is
removed before installing the
chassis in the wall sleeve.

4. Slide the chassis into the wall
sleeve until the chassis flanges
contact the front edge of the wall
sleeve. See Figure 14.
5. Secure the chassis to the wall
sleeve using three screws on
each side of the chassis to ensure
a proper seal between the
chassis and the wall sleeve . The
screws are supplied in a plastic
bag which is attached to the
power cord. See Figure 15.
6. Verify the indoor and outdoor
grilles are free of airflow
obstructions.
7. Make the power supply
connections as detailed in the
next step.
Step 6. Install unit power
supply.
Note: For installation procedures,
please refer to the Installation
Guide that accompanied the
accessory.
