the circuit breaker mounting bracket as shown in Figure
3, using the supplied screws. Insert the four (4) screws
as shown in Figure 3 (two through the control panel
flange and two into the cabinet corner post).
For 25kW applications, see Figure 4 for installation.

WARNING
1. All electric heat kits have lugs for connection of high
voltage power supply. Insert the power leads into the
lugs (either on the terminal block or circuit breaker)
and tighten. The power must be routed through a strain
relief as they enter the cabinet. For two power supply
electric heat kits (all circuit breaker connections), be
sure to connect the correct power supply to the correct
circuit breaker – check the air handler rating plate for
Minimum Circuit Ampacity and Maximum Overcurrent
Protection electrical ratings of each circuit.
2. Connect the ground wire from the power supply to the
ground lug provided in the air handler. For two power
supply electric heat kits, one ground lug is provided
with the air handler and the second ground lug is supplied
with the electric heat kit (on the circuit breaker
mounting plate). Use proper torque to secure the ground
wire to the ground lug.
3. For low voltage connections, remove the female multi-
pin connector with the jumper wire provided with the
air handler from the male multi-pin connecter provided
with the air handler. Insert the female multi-pin
connector provided with the electric heat kit into the
male multi-pin connector provided with the air handler.
Note:
it can be inserted in one position only.
4. FOR ALL THREE PHASE APPLICATIONS: Wire the terminal
block leads to the transformer as per the wiring diagram
on the heat kit. Insert single and three phase power
leads into the lugs provided on the terminal block and
the circuit breaker respectively, and tighten.
