NOTES: 1. Blower performance includes a wet evaporator coil and 2" filters.
2. Units include a baffle to direct the proper flow of air across the electric heaters. On “cooling only” applications, this baffle MUST be removed to get the ESP values listed in
the above tables.
3. Refer to Table 6 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.
