INSTALLATION
1. The amperage rating of the disconnect
must be equal to or greater than the
amperage rating on Table A and as
marked on the nameplate located on the
bottom access door (Figure 1).
2. The power disconnect kit is to be installed
in the rectangular knockout located in the
bottom right corner on the back of the
heater (Figure 2). The knockout can be
removed using a hammer and chisel or
other appropriate means.
For easier access to terminal screws to
wire pigtail leads supplied on the heater, it
is suggested that these connections be
made before installing. See Wiring
Instructions.
3. The disconnect switch assembly (Figures
3 or 4) consists of a mounting bracket,
disconnect switch, mounting plate cover
and self tapping screws.
4. The Disconnect switch, with its mount-ing bracket should be
inserted into the heater cabinet by opening the bottom service
door and positioned behind the opening created in Step 2 (see
Figure 5).

5. The disconnect switch, with its mounting plate should be inserted
into the heater cabinet by opening the bottom service door and
positioned behind the opening created in step 2 (see Figure 5).
6. Insert the four self tapping screws into the four holes in the rear
panel. They should engage the holes in the mounting plate and
then be tightened until they are secure (see Figure 6).
7. Mount the switch faceplate to the switch using the two provided
screws. Mount with the “OFF” position to “0” to the left and the
on position “1” to the top. Slide the handle over the shaft and
tighten the screw to secure.
