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.
