Operating conditions

1. The ambient air temperature is from -5℃ to +40℃, 24-hour average does not excead +35℃;
2. Installation site altitude does not exceed 2000m;
3. Atmospheric relative humidity is less than 50% when the ambient air temperature is +40°C, and higher relative humidity is allowed at a lower temperature. In wet months, the average maximum humidity is 90%, while the monthly average minimum temperature is +25°C, and the change of gel surface temperature should betaken into account.
