Line Voltage Connections
WARNING
Electrical Shock Hazard
Electrically ground furnace.
Connect ground wire to ground terminal
marked "GROUND".
Use copper wire for supply connection.
Correct wire gauge is shown in the chart below.
Failure to follow these instructions can result in
death or electrical shock.

1. Disconnect power.
2. Remove the blower access panel.
3. Remove the burner access panel.
4. Route the field supply wires through the line voltage conduit
opening to the electrical connection area, providing sufficient
length to connect to the pigtail leads.
5. For single phase units:
Connect the field supply wires (L1, L2) to the 2 black
pigtail leads using UL listed wire nuts.
8
For three phase units:
NOTE: Check compressor operation for proper rotation. If the
rotation is not correct, then reverse any two leads (for example:
L1 and L2). Incorrect rotation is identified by excessive sound or
improper system pressures.

1. Route the low voltage supply wires through the low voltage
entry opening to the low voltage connection area providing
sufficient length to connect to the low voltage pigtail leads.
2. Using UL listed wire nuts, connect the low voltage supply
wires to the matching colors of the low voltage leads.
3. Replace the burner access panel.
4. Replace the blower access panel.
