*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.

1Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.
2
The pressure thru 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.
