C - Rotate the circuit breaker 180 degrees.
D -  Slide the circuit breaker back on the rail and secure 

in place with previously removed screw.

2 -   The air handler access panels are factory supplied. 

There is a patch plate over the circuit breaker 

opening. Remove the circuit breaker patch plate 

from the air handler access panel. See figure 4.

4 -   Choose the appropriately sized adhesive-backed 

circuit breaker seal and remove any perforated 

sections (if needed). Apply the seal to the outside of 

the air handler access panel so that the seal is snug 

around the circuit breakers. 

5 - 

 Break the patch plate for the specific size of electric 

heat section that you are installing. Discard the 

unused piece of patch plate (see figures 5 and 6). 

6 -   Secure the patch plate on the air handler access 

door.
