Mechanical Specification Options
General
The outdoor condensing units are factory charged with the system charge required for the outdoor condensing unit, ten (10) feet of tested connecting line, and the smallest rated indoor evaporative coil match. This unit is designed to operate at outdoor ambient temperatures as high as 115°F. Cooling capacities are matched with a wide selection of air handlers and furnace coils that are AHRI certified. The unit shall be certified to UL 1995. Exterior is designed for outdoor application.
Casing
Unit casing is constructed of heavy gauge, G60 galvanized steel and painted with a weather-resistant powder paint on all louvers and panels. It features a corrosion and weatherproof CMBP-G30 DuraBase™ base.
Refrigerant Controls
Refrigeration system controls include condenser fan, compressor contactor, and high pressure switch. High and low pressure controls are inherent to the compressor. A factory installed liquid line drier is standard.
Compressor
The Duration® 2-stage compressor features internal over temperature and pressure protection and a hermetic motor. Other features include roto lock suction and discharge refrigerant connections, a centrifugal oil pump, and modular plugs for electrical connections.
Condenser Coil
The outdoor coil provides low airflow resistance and efficient heat transfer. The coil is protected on all four sides by louvered panels.
Low Ambient Cooling
As manufactured, this unit has a cooling capability down to 55°F. For low ambient cooling below 55°F, refer to Application Guide APP-APG014-EN.
