1. Add these values to the available static resistance in the respective Blower Performance
Tables (ZF, ZR Only).
Economizer 2 3
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.
