Notes:

Constant speed units are rated at capacities shown in regular type; capacities in italic faced type apply only to units with multi-speed motors.

To determine BTU per hour capacities at various steam pressures and entering air temperatures, use conversion factors from Table SP-7, page 18. Final temperatures at new conditions can be calculated by applying basic formula.

Table SP-6 – Maximum Spread (Ft.)

Spread (Ft.)	15	17	20	24	26	27	28	32	35	37	45	50	54	57	60

Note:

The “spread” is the diameter of the comfort zone at floor level, projected by the Model P unit without the louver cone diffuser, based on two pounds steam pressure and 60 F entering air.
