NOTES FOR TABLES 13 THROUGH 32:

“Turns Open” refers to the setting of the variable pitch motor sheave, where “0 Turns Open” is fully closed.

Blower performance includes dry coil and 2” (51mm) throw-away filters.

Blower performance for gas heat includes the maximum number of heat tubes available for each tonnage.

ESP (External Static Pressure) given is that available for the supply and return air duct system. All internal resis- tances have been deducted from the total static pressure of the blower.
