Performance based on 2# steam pressure (13.8 kpa) at heater with air entering @ 60°F (16°C). For Sound Ratings See Pages 28 and 29.

Use conversion table for all metric conversions.

* For the lower output, an optional Speed Controller must be ordered.

†Stated AMP is full load for the standard motors. AMP draw varies by motor manufacturer ± 0.2 AMPS. Please see your unit's motor data plate for exact (FLA) Full Load Amp rating.
