1.
Deduct these resistance values from the available external static pressures shown in the respective Blower Performance Table (See Note 2 for
exception.)
2.
Since the resistance to air flow will be less for horizontal duct connections than for bottom duct connections, add these pressures to the ESP values
on the respective unit's blower performance table.
