cooling operation down to 40F (4.4C). It’s high efficiency design ensures high performance with most duct systems. REFRIGERANT SYSTEM is designed to provide dependability. Liquid refrigerant filter driers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full refrigerant charge and is fully run tested. Refrigerant service connections make checking operating pressure easier.

The SHC is based on 80_F (26.7_C) edb temperature of air entering evaporator coil. Below 80_F (26.7_C) edb, subtract (corr factor x CFM) from SHC. Above 80_F (26.7_C) edb, add (corr factor x CFM) to SHC. Correction Factor = 1.10 x (1 --- BF) x (edb --- 80).
