Operating Requirements	2-13

Table 2-4 shows the system’s atmospheric requirements.

Table 2-4. Atmospheric Requirements

Temperature1 (° F)	Relative humidity (%)	Air pressure (psi)
65 to 85	20 to 60	9.4 to 15.2

1.For customer sites at altitudes above 5000 feet, subtract 1°F from the maximum temperature for every 1000 feet over 5000. For example, the maximum temperature at 6000 feet is 84°F; the maximum temperature at 7000 feet is 83°F

Table 2-5 shows the system’s tolerance for airborne contaminants.
