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