Field Wiring
CAUTION
Internal power wiring to the compressors for single and multiple point option are different.
Field wiring must be installed according to unit wiring diagram.
Wiring must comply with all applicable codes and ordinances. Warranty is void if wiring is not in
accordance with specifications. Copper wire is required for all power lead terminations at the unit.
Aluminum or copper can be used for all other wiring.
Standard AGR units have internal power wiring for single point power connection. A single
large power terminal block is provided and wiring within the unit is sized in accordance with the
National Electrical Code. A single field supplied fused disconnect is required. An optional factory
mounted transformer may be installed.
If the evaporator heater is on a separate disconnect switch from the main unit power supply, the
unit may be shut down without defeating the freeze protection (115V, 420W heat tape) provided by
the cooler heater.
