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.
