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.)
Unit No. 42P 64P 80P
Spread (Ft.) 15 17
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.
