NOTES:
1. Airflow expressed in standard cubic feet per minute (CFM) and in cubic meters per minute (m
3
/min).
2. Return air is through side opposite motor (left side).
3. Airflows above 1800 CFM (50.97 m
3
/min) require either return from two sides or one side plus bottom.
4. Motor voltage at 115 V.
5. NR = Operation at this static pressure is not recommended.

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.
NOTE - The ADJ “D” tap should not be used.
