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.
