NOTES:
1. Blower performance includes a gas-fired heat exchanger, fixed outdoor air, two-inch T/A filters and a dry evaporator coil.
2. Refer to the additional Static Resistances table.
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.
