≤ 10% of annual operating hours: 5°C to 40°C at 5% to 85% RH with 26°C dew point.
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 175m above 950m (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.
Outside the standard operating temperature (10°C to 35°C), the system can operate down
to –5°C or up to 45°C for a maximum of 1% of its annual operating hours. For
temperatures between 40°C and 45°C, de-rate maximum allowable dry bulb temperature
by 1°C per 125m above 950m (1 °F per 22 ft).
