1. Deduct these resistance values from the available external static pressure shown in Tables 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.
