The maximum operating pressure specified in the manual is 2.0 bar or the lower limit indicated on the unit’s nameplate. The set pressure of the pressure relief valve must not exceed this limit; a specialist must verify suitability and the proper functioning of the protection.

The thermal protection system for the Alfa 70 ET version described in the factory manual uses a built-in cooling coil and an external thermal protection valve; this protection is mandatory in a closed system. The cooling water supply and safe drainage must function even during a power outage. Before connecting, verify that the actual unit complies with this version.
