NOTES: 1. Blower performance is based on cooling only unit, with fixed outdoor air, 2" T/A filters and a dry evaporator coil.
2. Refer to Page 14 for additional static resistances.
ESP = External Static Pressure available for the supply and return air duct system. All internal unit resistances have been deducted from the total static pressure of the blower.
* Do NOT close the pulley below 1 turn open.

All motors have a nominal speed of 1450 RPM, a 1.15 service factor and a solid base. They can operate to the limit of their service factor because they are located in the moving air, upstream
of any heating device.
