NOTES: 1. Blower performance includes fixed outdoor air, standard unit filters, a dry indoor coil and no electric heat.
2. Refer to Table 5 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.
