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 fo
r 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.
