Environmental Installation Conditions - Borri STS 16A User Manual

3.2.1 Environmental installation conditions

The air is classified by the EN 60721-3-3 standard (Classification of environmental parameters
and their severities – Stationary use at weather-protected locations) based on climatic and
biological conditions as well as on mechanically and chemically active substances.
Therefore the place of installation must meet specific requirements to ensure compliance with
the conditions for which the STS / ITS was designed.
