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.

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.
