Installing The Return Air Panel Door
1. Install the return air panel door assembly (Figure 40).
Center, level and plumb the frame inside the framed
opening. Push the assembly into the opening until the
gaskets compress against the cabinet, and the frame face
is tight to the nished wall.
Notes: 1. Shims (eld-supplied) should be used to make up the
space between the studs and the panel frame at the
locations of the fasteners on the panel frame (4).
Adhere them to the panel frame to keep them in
place (Figure 40).
2. Be sure the bottom ange of the door frame slides
beneath the cabinet ange, as shown in Figure 40.
This seal must compress between the bottom
panel ange and the bottom cabinet ange when the
installation of the panel door frame is complete.
2. Check that the panel door frame is centered within the
opening and seals completely to the cabinet return air
opening. Also conrm that the room side ange of the
frame is level, plumb and rmly against the drywall. Secure
the hinged panel door frame with the appropriate fasteners/
screws (eld provided).
Note: Before proceeding to instruction 3, be sure to clean
frame with rubbing alcohol to remove any oils or dust to
ensure a strong bond between velcro and door frame.
3. Remove the backing on the (hook) velcro strips and
rmly press the cover plate to the panel door frame in the
location shown in Figure 40.
Note: The clearance holes along the top edge of the cover
plate should t around the screws on the underside of
the top door frame.
