3. Locate dimensions A and B for sheet rock opening size.
The position of the sheet rock opening must be
centered side-to-side with the return-air opening in the
cabinet. Ensure the bottom of the sheet rock opening is
2¼” below the return-air opening in the cabinet.This
allows the door recess to rest on the bottom of the
sheet rock opening for proper vertical placement of the
door.
4. Place the door frame into the sheet rock opening. A
positive seal is critical between the back of the door
frame and the front of the cabinet. Ensure that the
gasket material seals properly.
Note: When placing the sheet rock panel, make certain
the opening for the door is centered with the
return-air opening in the cabinet (±1/8").
8. Install Filter.
9. Vacuum all dust and construction debris from unit after
cutting out supply/return openings.
Supply Air Ductwork
A 2" (50.8 mm) duct flange may be required to help
eliminate supply air from recirculating back into the return
air, air-to-refrigerant coil prior to discharging into the
space.
Equipment containing a top discharge, ducted design:
install field ductwork to the unit providing a water tight
flexible connector at the unit.This helps prevent operating
sounds from transmitting through the ductwork. Elbows
with turning vanes or splitters are recommended to
minimize air noise due to turbulence and to help reduce
static pressure.

studs using the holes located in
the door frame and field provided
screws.
Note: If the gap between the door
frame, and the side stud is
over 1/16-inch, place a shim in
between the door frame and
