Specications
≤ 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 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 125 m
above 950 m (1°F per 228 ft).
