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.
** Factory setting.

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.

Deduct these resistance values from the available unit ESP values listed in the respective blower performance table except for Horizontal Duct Connections
(Shaded ).
Add these values due to less airflow resistance.
