Comfort-Aire’s HRG16 Series is available in 1 1/2- to 5-ton capacities. The 16 SEER heat pumps feature a full metal jacket, polyester urethane finish, copper tube and aluminum fin coils. A high-pressure switch protects against excessively high system pressures and a liquid line filter-drier is included for field installation. Compressor and control access is located on the side of the unit in a waterproof housing. Suction pressure can be read without removing any panels and the top grille assembly provides access to components without disconnecting the fan motor.
