INSTALLER'S GUIDE
STEP 4 - (Optional) Rotate Circuit Breaker Assembly.
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 careful of
sharp edges on equipment or any cuts made on sheet metal while
installing or servicing. Personal injury may result.

CAUTION
!
1. Unscrew the Breaker Bracket from the Base Plate
using a magnetic 1/4" hex driver with an extension.
The extension allows for easier access to the screws
which are located at the back of the bracket.
2. Rotate the bracket with circuit breaker(s) 180 °.
3. Use the screws removed in action 2 (above) to secure
the bracket to the Base Plate.
Note: For LG (lug) heater models the terminal block
bracket does not rotate.
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.

STEP3 - Attach Retainer Tabs and Edge Guard
Note: For A cabinet widths, only the right side
retainer tab must be installed.
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: If no filler plates are needed, the retainer tabs
must be attached to the heater coil flange. 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. Cut
the edge guard to the length needed for the heater
width, including the filler plates.
3. Install the edge guard on the front of the heater flange
as shown.
