heaters or if an older unit is being replaced, the supply power
wires must be checked to make sure the wires are the proper
sizes to handle the current load for the heaters Refer to Tables 6-
8 for correct wire size. If the supply power wire size is incorrect,
new wires will need to be installed. Follow the instructions
“Power Supply Wiring” on page 8 of these instructions for
proper installation.
For circuit breaker models only -
After the supply wiring has
been connected to the circuit breakers you must remove the
transformer and indoor blower motor wires from the terminal
block and connect them to load side of circuit breaker #1.
