Cabinet—Galvanized steel with powder coat paint finish. The powder coat paint finish is high gloss, durable and capable of withstanding a 1000-HR salt spray test per ASTM B117. The unit is of the frame and panel type of construction which allows all access panels to be opened or removed without affecting the structural strength of the unit. Fastening screws are also of the 1000-HR type. Stamped louver panels offer 100% protection for the condenser coil are standard.

Base Pan—Galvanized steel with powder coat paint finish.

Compressors—The compressor is single speed with a fully hermetic scroll on -AWD-100, -125 and -151 [35.2, 44.0 and 52.8 kW] models. The compressor is tandem scroll set on -AWE-181 and -241 [52.8 and 70.3 kW] models. Modulation (50%) is available on -AWE-181 and -241. All compressors have inherent high temperature protection.

Condenser Coil—Constructed with copper tubes and aluminum fins mechanically bonded to the tubes for maximum heat transfer capabilities. All coil assemblies are leak tested up to 450 PSIG [3100 kPa] internal pressure.

Refrigerant Connections—All field sweat joints are made external of the unit, and are located close to the ground for a neat looking installation.

Crankcase Heaters—Standard on all models, except -AWD-151.

Low Ambient Control—A pressure sensitive fan cycling control allows operation down to 0°F [–17.8°C].

Service Valves—Standard on liquid line for all models. Optional on vapor line.

Service Access—Control box with separate line and control voltages, as well as compressor and other refrigerant controls are accessible through access panels. These panels may be open or completely removed without affecting normal operation of the unit.

High Pressure Control—Manual reset control deactivates system (opens contactor circuit) if abnormally high pressure occurs.

Low Pressure Control—Automatic reset control deactivates system if abnormally low pressure or refrigerant loss occurs.

Condenser Fan Motors—Direct drive, single-phase permanently lubricated “PSC” motors with inherent thermal overload.

Transformer—75VA step-down type, line to 24 volts.

—An electrical switch which operates the compressor and condenser fans. Its 24 volt coil is activated through the high pressure control and low pressure control on a call for cooling.

—All units are run-tested at the factory prior to shipment. Units are shipped with a nitrogen holding charge.

Equipment Ground
—Lug for field connection of ground wire.
