Expanded Operating Temperature
NOTE: Outside the standard operating
temperature (10 °C to 35 °C), the system can
operate down to 5 °C or up to 40 °C for a
maximum of 10% of its annual operating
hours.
For temperatures between 35 °C and 40 °C, de-
rate maximum allowable dry bulb temperature by
1 °C per 175 m above 950 m (1 °F per 319 ft).
< 1% of annual operating hours –5 °C to 45 °C at 5% to 90% RH with 26 °C dew
point.
NOTE: Outside the standard operating
temperature (10 °C to 35 °C), the system can
