2. Altitude for installing place should not exceed 2000m;
3. When the ambient air temperature is +40, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is +25oC, and condensation on the product surface caused by temperature change should be taken into consideration.
