1
Unit resistance is based on a wet indoor coil and clean filters.
2
Available static pressure in IWG to overcome the resistance of the duct system and any accessories added to the unit. Refer to the Tables 6 & 7 for the resistance of these accessories and for
additional motor and drive data .
3
Motors can be selected to operate into the service factor because they are located in the moving air stream, upstream of any heating device.
