NOTES:

Constant speed units are rated at capacities shown in regular type; capacities shown in italic faced type apply only to units with multi-speed motors. ** Performance data based on 2 lbs. steam pressure at heater with air entering @60°F.

To determine BTU per hour capacities at various steam pressures and entering air temperatures, use conversion factors from Table 7. Final temperatures at new conditions can be calculated by applying basic formula.
