NOTE:
Air flow data shown above 1/2” w.c. external static pressure is for REFERENCE ONLY. Maximum allowable external static when electric heat is used is limited to
1/2” w.c. Maximum allowable external static pressure may also be limited by minimum CFM requirements for proper Heat Pump operation.
1. Dry coil conditions only, tested without filters.
† Speed temp High #1 not recommended for the unit.
Air handler units are UL Listed up to 0.5" w.c. external static pressure, including air filter, wet coil, and largest kW size heater, unless otherwise noted.
