1. Deduct these resistance values from the available external static pressure shown in Table 8, 9, 10, and 11
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.
