ENVIRONMENTAL REQUIREMENTS

Temperature and Humidity

The system equipment should be installed in a well-ventilated area. Maximum equipment perfor-

mance is obtained at an ambient temperature between 40 and 120 degrees Fahrenheit (4 and 49

degrees Celsius) for short term operation and up to 110 degrees Fahrenheit (43 degrees Celsius)

for continuous operation. The relative humidity range is 10 to 95 percent up to 84 degrees

Fahrenheit (29 degrees Celsius). Above 84 degrees Fahrenheit (29 degrees Celsius), maximum

relative humidity decreases from 95 percent down to 32 percent at 120 degrees Fahrenheit (49

degrees Celsius). Installations outside these limits may reduce system life or impede operation.

Table AK correlates room temperature with allowable relative humidity.

The system equipment can operate at the maximum short-term operational limits for a period not

to exceed 72 consecutive hours or a total of more than 15 days in a year. For altitudes above

5,000 feet, reduce the maximum short-term temperature limit by 1 °F for each 1,000 feet of

elevation above 5,000 feet. At 10,000 feet, for example, the maximum short-term temperature

limit is 115 °F.
