Above data includes allowances for a dry evaporator coil, gas heat exchanger and no filters. For additional pressure drops, refer to
Tables 14 and 15.

DESCRIPTION
WET EVAPORATOR COIL

ECONOMIZER
FILTER FRAME KIT
1.
Deduct these resistance values from the available external static pressure shown in Tables 10, 11, 12, and 13.
2.
The pressure through the economizer is greater for 100% outdoor air then for 100% return air. If the resistance of the return air
duct system is less then 0.25 IWG, the unit will deliver less CFM during full economizer operation.
