All CFM’s are shown at 0.5” w.c. external static pressure.These units have variable speed motors that automatically adjust to provide constant CFM from 0.0” to 0.6” 
w.c. static pressure. From 0.6” to 1.0” static pressure, CFM is reduced by 2% per 0.1” increase in static. Operation on duct systems with greater than 1.0” w.c. external 
static pressure is not recommended. 
NOTE: At some settings, LOW COOL and/or LOW HEAT airflow may be lower that what is required to operate an airflow switch on certain models of electronic air 
cleaners. Consult the instructions for the electronic air cleaner for further details.
The ADJ “D” tap should not be used.
