INSTALLER'S GUIDE
STEP 4
- (Optional) Rotate Circuit Breakers.
The need to reorient the Circuit Breaker Assembly
depends upon the orientation of your application
and which of the high voltage electrical conduit entry
points you use for high voltage wiring.
SAFETY HAZARD!
Sharp Edge Hazard. Be care-
ful of sharp edges on equipment or any cuts made
on sheet metal while installing or servicing. Personal
injury may result.
CAUTION
1. Pull out the tab on the back side of the breaker using
a long screwdriver.
2. Remove the circuit breaker from the control box and
rotate the circuit breakers 180 °.
Important:
For air handler units installed in the
horizontal right position, the circuit breakers on
the heater must be rotated in order to comply with
National Electric Code (NEC Section 240.81). The
NEC requires that circuit breakers operated verti-
cally must be oriented so that the "on" position of the
breaker is upward.

STEP 3 -
Attach Retainer Tabs.
1. Add the Retainer tabs using the screws provided (both
tabs and screws are located in the documentation
packet).
Leave the screws slightly loose so that the tab can slide
to the left or right as needed. The tab will be used later
to engage in a slot within the air handler cabinet.
Note: The retainer tabs must be attached to the
heater base plate. Leave the screws slightly loose
so they can be slid to the left or right as needed.
2. The edge guard is located in the document pack. Install
the edge guard on the front of the heater flange as
shown.
