CLOSET AND DRYWALL INSTALLATION
To avoid potential vibration and noise is-
sues, the RA panel should not contact any
part of the unit cabinet or sleeve. Maintain
a sufficient gap between RA panel frame
and cabinet.
Build a closet enclosure for the cabinet that incorpo-
rates the RA panel size while maintaining a sufficient
gap between the closet and cabinet. This prevents the
cabinet from contacting the RA panel and closet enclo-
sure. Refer to
Acoustic Return Air (RA) Panel on page
21 , Figure 13 on page 22 , and Figure 14 on page
23 .
1. Cover the supply and return openings with plas-
tic or cardboard before installing drywall around
cabinet. This prevents dust or debris from entering
the unit components.
2. Install the drywall using conventional construc-
tion methods. Do not fasten studs or drywall di-
rectly to the cabinet surface. Space the framing
members according to the RA access and the type/
quantity of supply air (SA) outlets. See Figure 13
on page 22 and Figure 14 on page 23 .
3. Install sheetrock around unit cabinet by securing
the drywall to the building construction studs.
4. Cut holes around the SA and RA openings to al-
low access to the unit chassis, unit controls, and
the SA connection.
5. Vacuum all dust and construction debris from the
unit drain pan, electrical box, and discharge ple-
num after cutting out the supply/returns openings.
To prevent electrical shorts and drain pan
leaks, DO NOT penetrate unit compo-
nents when driving screws near the unit
control box or drain pan. Do not allow
screws or nails to penetrate chassis, risers,
electrical junction boxes, conduits, or to
interfere with chassis removal.
ACOUSTIC RETURN AIR (RA) PANEL
RA panels are painted standard appliance white. Care-
fully unpack RA panels from their shipping box. RA
panels with optional key locks require the key locks
to be field installed to the slot in the panel door. ADA
RA door panels come with an opening and pilot holes
mounting a thermostat. The ADA harness for wiring
the thermostat and connecting to the unit is shipped
loose with the thermostats.
1. Locate the drywall opening at a distance from
the unit so that it prevents the RA panel from
contacting the unit sleeve. See Figure 13 on page
22 and Figure 14 on page 23
.
2. Center the RA panel throat opening to the unit
cabinet RA flange opening.
3. Fasten the RA panel to frame opening using the
screws provided. See Figure 13 on page 22 .
Figure 16 on page 24 shows the opening for mount-
ing an ADA compliant thermostat at 48 inches above
floor. Note that location of the opening on the door
changes if the cabinet is ordered with a stand. A left
hand opening door is shown. The RA panel with ADA
is not reversible. It must be ordered in either a left or
right-hand opening configuration, determined by the
location of the door hinge.
