NOTES: 1. Blower performance includes a wet indoor coil and 2" filters.
2. Blower performance includes the maximum number of heat exchangers.
3. Refer to page 8 for the resistance of the unit accessories.
ESP = External Static Pressure available for the supply and return air duct sytem. All internal unit resistances have been deducted from the total static pressure of the blower.
