NOTE: These units are equipped with a variable speed (ECM) indoor motor that automatically adjusts itself to maintain approximately the same rate of indoor airflow in both heating and cooling, dry and wet coil conditions and at both 230/ 208 or 460 volts.
1 Maximum ESP (inches WC) shown is with 2" thick disposable filter.
2 Rated CFM for 2nd Stage Operation – required for maximum performance rating.
3 1st Stage – the CFM output on 1st Stage Heating or Cooling.
4 Blower only CFM is the total air being circulated during continuous fan mode.
