1. Blower performance includes two-inch throwaway filters and maximum number of heat tubes available for each tonnage.
2. ESP (External Static Pressure) given is that available for the supply and return air duct system. All internal resistances have been deducted from the total static
pressure of the blower.
3. "Turns Open" refers to the setting of the variable pitch motor sheave, where "1 Turn Open" is fully closed. DO NOT close the pulley below one turn open.
