5. For E2 electric furnaces, attach the foam “standoff”
to the bottom corner on the back side of the sheet
metal box opposite the side where the bracket is
attached (see Figure 5). This “standoff” will prevent
movement of the switch box when the homeowner
moves the switch.
6. Attach the appropriate brackets to the sheet metal
box and secure assembly to blower (see Figure 6).
NOTE: The blower may need to be pulled out of the
furnace slightly in order to secure the brackets.
7. Connect the blower plug to the wiring harness and
connect the other plug on the wiring harness to the
control panel where the blower plug was removed.
8. Bunch excess wire from wiring harness together and
secure with a wire tie to keep away from blower.
9. Remove the nameplate insert from furnace door and
replace it with the door control frame provided in the
extra parts package (see Figure 1 or 2).
10. Attach the appropriate brand label supplied in the
extra parts package to the sheet metal switch cover
so that it may be seen through the door control frame
in the furnace door when it is replaced.
