NOTES:
1. Subcircuits are internal heater circuits of 48 amps or less.
2. Electric heat performance is not within the scope of AHRI standard 430 certification.
3. To avoid damage due to overheating, minimum face velocity cannot fall bellow 350
fpm.
4. Heaters up to (and including) 60 kW have 3 control steps; beyond 60 k, 6 steps are
standard.
5. Heater kW offering is controlled by AHUBuilder® program. This table is for reference
only.
