WARNING

Undersized wires can cause poor
equipment performance, equipment
damage, or fire. Consult the NEC, CEC or
a qualified electrician for proper wire size.

WARNING

To avoid personal injury, shock, or death,
be sure wiring to the unit is properly
grounded.

WIRING
Wire size is important to ensure proper unit operation. The
size must be sufficient to carry the minimum circuit ampacity
listed on the unit serial data plate. Amana recommends
sizing the wires to limit the voltage drop to a maximum of
2% from the main breaker or fuse panel to the outdoor unit.
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.

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.

NOTE: This table is provided as a guide only. Wire
sizing may be regulated by local codes. Local inspection
is the final authority on wire sizing.

WARNING

To avoid personal injury, shock, or death,
open the electrical disconnect switch
before electrically connecting the unit.
Wiring must conform with National
Electrical Code (NEC) or Canadian
Electrical Code (CEC) and all local codes.

The wiring diagram for this unit can be found on the control
box cover. Refer to Figure 3 for field wiring connections.
