1.Deduct these resistance values from the available external static pressure shown in SUPPLY AIR BLOWER PERFORMANCE Tables.

2.Add these resistance values to the available static resistance values on SUPPLY AIR BLOWER PERFORMANCE Tables.

3.The pressure through 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.
