1. Electric heat steps and airow range depends on voltage and
size. Consult the air pressure drop tables for specic number
of steps for a given voltage.
2. Weights are for components only and need to be added to the
extended cabinet weights. The diffuser is required in the ex-
tended cabinet for any unit with hot water or nal lter option.
