English to Italian Tech/Engineering Mechanics / Mech Engineering ultrapure water system

The following criteria must be considered when the installation area is selected:
􀂾 Feedwater pressure at least 0.1 bar, at most 6 bar.
The feedwater pressure must not exceed 6 bar. With higher pressures, a pressure reducer must be installed.
􀂾 Minimum temperature +2°C
􀂾 **Level standing surface**
􀂾 The **standing surface** or the wall where the system is to be stood or mounted must
have sufficient weight-bearing capacity (see Technical specifications for weight).
􀂾 The ultrapure water system only be mounted on a concrete wall or a solid masonry.
􀂾 DN 50 floor drain
􀂾 Unrestricted gravity fall to the floor drain.
Should a floor drain not be available, install a Water Watcher (Article No.: ) to
protect against water damage!

Dovrebbe essere una sorta di superficie di appoggio, ma quel level?
