Installation of Recessed Wall
Housing in New Construction
1. Mounting Wall Housing (See Figure 1).
a. Place the wall housing between two 16" (406 mm)
center-to-center wall studs at the desired mounting
height but no closer than 8" (203 mm) to adjacent wall
or floor.
b. Align wall box such that the bottom and sides will be
flush with finished wall surface (top flange of wall box
should protrude approximately 1/2" (12.7 mm) from fin-
ished wall surface).
c. Secure the housing in position with wood screws or
nails as shown in Figure 1.

2. Power Supply Wiring (See Figure 1)
Note: Wire compartment volume - 119in
a. Run a power supply cable into the knockout area in the
upper right hand corner of the housing. All wiring must
be in accordance with National and Local Electrical
Codes. Refer to Table 1 for correct wire size.
b. Remove disconnect switch bracket by loosening two
screws on the right side.
c. Install a cable clamp in the "knockout" in the top of the
wall housing.
d. Insert power supply cable through cable clamp, allow-
ing at least 6" (152mm) of leads to extend inside the
housing. Connect the blue lead wires of disconnect
switch to the supply wire leads using wire connectors
(see wiring diagram, pg. 3).
e. Ground the housing using the green screw located in
the inside top of the housing.
f. Secure disconnect switch bracket in place by tighten-
ing screws.
Installation of Recessed Wall Housing

1. Provide a wall opening 14-1/2" (362mm) wide by 18-1/2"
(470mm) high at the desired mounting height, but no
closer than 8" (203mm) from floor. (See Figure 2.)
2. Power Supply Wiring

b. Remove disconnect switch bracket by loosening the
two screws on the right side.
c. Install a cable clamp in the "knockout" in the top of wall
housing.
d. Insert power supply cable through cable clamp, allow-
ing approximately 6" (152mm) of cable length to
remain inside the wall housing to facilitate connections.
3. Mounting Wall Housing
a. Place the wall housing into wall opening flush with fin-
ished wall surface on bottom and sides of box. (Top
flange of wall box should protrude approximately 1/2"
or 12.7mm from finished wall surface).
b. Secure the wall housing in place with wood screws or
nails.
4. Wiring Disconnect Switch
a. Connect the power supply wires to the blue wires of the
3
(1950cm

).
disconnect switch using wire connectors (see wiring
diagram, pg. 3.)
