1. All CFMs are shown at 0.3" w.c.external static pressure. These units have variable-speed ECM motors that automatically adjust to provide constant CFM from
0.0" to 0.4" wc. external static pressure. From 0.4" to 0.8" external static pressure, CFM is reduced by 2% per 0.1" static pressure. Operation of these units on duct
systems with external static pressure greater than 0.8" is not recommended.
At some settings, airflow may be lower than 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.
Data is for 208V or 230V.
2. The ADJ "D" tap should not be used.
