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 O 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.
