Figures in bold face show maximum mounting height with louver cone diffusers set vertically.
Above table based on 60°F entering air temperature. In providing for the use of diffusers, it must be remembered that adjustment of a LCD to deflect air
toward horizontal immediately lowers the mounting height limit.

Note: The "spread" is the diameter of the comfort zone at floor level. The above table represents the spread for standard units without a louver cone
diffuser and mounted at its maximum height at 2 psi (13.8 kPa) steam pressure and 60°F (16*C) entering air. (See Tables 21 and 22 for maximum moun
