*.
Add these resistance values to the available static resistance in the respective Blower Performance Tables.
†.
Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.
‡.
The pressure drop 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.
