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