NOTES:
1. Blower performance includes fixed outdoor air, 2" T/A filters, a dry evaporator coil and no electric heat.
2. Refer to Table 13 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.
