ISA71.04-1985.
<200 Å/month as defined by AHSRAE TC9.9.
Specifications
5°C to 40°C at 5% to 85% RH with 29°C dew point.
NOTE: Outside the standard operating temperature
(10°C to 35°C), the system can operate continuously
in temperatures as low as 5°C and as high as 40°C.
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).
–5°C to 45°C at 5% to 90% RH with 29°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 temperature by 1°C per 125 m above
950 m (1°F per 228 ft).
