B-Changing Circuit Breaker Orientation
The air handler comes from the factory setup for horizontal
left-hand discharge which requires no change in the circuit
breaker orientation. However, if the air handler is installed in
a horizontal right-hand discharge position, rotate the
breaker 180º. The circuit breaker orientation change is
required by UL 1995, Article 26.18 (25 September 2005).
1. The factory default configuration for the two circuit
breakers is horizontal left-hand discharge which
requires no change (see figure 16). To change the
applicable circuit breakers orientation for right-hand
discharge, proceed to step 2.
2. Locate the one clip which is located on the right side of
each breaker (see figure 15). The clip secures the
circuit breaker to the mounting bracket. Pull the clip to
release the breaker from the mounting bracket.
3. Flip the breaker so that the wires attached to the circuit
breakers terminals are on the left side (see figure 16).
4. Use the black clip to reattach the circuit breaker to the
mounting bracket.
