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

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.

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. Route the power supply and ground wires through the

high voltage entrance in the unit. Connect the power

supply wires to the contactor. Connect the ground wire

to the ground lug.

2. Route the low voltage wiring through the low voltage

entrance in the unit. Connect the low voltage wires to

the terminal strip.

3. If an Amana approved room thermostat is not already

present, install one at a suitable indoor location. Con-

sult the instructions packaged with the thermostat for

mounting and location instructions. For field-supplied

low voltage wiring and connections, see the last section

of this manual.

4. Check all factory wiring connections to ensure none

were loosened during shipping and handling.

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.
