1. Airflow at nominal voltage, bottom return at 0.5 external static pressure, tested without filter installed, dry coil conditions.
2. These units have variable speed motors that automatically adjust to provide constant CFM from 0.0” to 0.6” w.c. static pressure.
3. From 0.6” to 1.0” static pressure, CFM is reduced by 2% per 0.1” increase in static.
4. Operation on duct systems with greater than 1.0” w.c. external static pressure is not recommended.
5. Both the COOL and the ADJUST tap must be set to obtain the cooling airflow desired (CFM).
6. The ADJ tap does not affect the HEAT tap setting.
7. Low speed cooling used only with two stage outdoor units. (Speed is preset to 65% of high speed).
8. Dehumidification speed is 85% of jumper selected COOL tap and ADJUST tap.
9. When operating in both heat pump and electric heat modes, the airflow (CFM) will be per HEAT Tap CFM values only.
10. At some settings, LOW COOL and/or LOW HEAT 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.
11. Airflow (CFM) indicator light (LED2) flashes once for every 100 CFM (i.e.: 12 Flashes is 1200 CFM) – blinks are approximate +/- 10% of actual CFM.
