RUN CAP

Consult the NEC, CEC, and all local codes to determine the correct wire gauge and necessary length of run for proper wiring.

1.To connect unit to power supply, route the power supply and ground wires through the high voltage entrance in the unit.

2.Connect the ground wire to the ground lug and power supply wires to the contactor.

3.Route the low voltage wiring through the low voltage entrance in the unit.

4.Connect the low voltage wires to the terminal strip (if present) or to the wire leads. Route the low voltage wire through the wire tie provided in the unit for restraint.

WARNING

To avoid the risk of fire or equipment damage, use only copper conductors.

5.Connect thermostat to unit. If an Amana approved room thermostat is not already present, install one at a suitable indoor location.

Consult the instructions packaged with the thermostat for mounting and location instructions. For field-sup- plied low voltage wiring and connections, see the last section of this manual.

6.Check all factory wiring connections to ensure none were loosened during shipping and handling.
