1Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.

2The pressure thru the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
