1 Add these values to the available static resistance in the respective Blower Performance Tables.
2 Deduct these values from the available external static pressure shown in the respective Blower Performance Tables.
3 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 is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
