1. All motors have solid bases and are inherently protected. these motors can be selected to operate into their service factor because they are located
in the moving air, upstream of any heating device.

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