Safety Valve - Atlantic CORTHERM 500 Installation, Betrieb Und Wartung

Important:
• If an array of several devices is installed, a valve assembly must be fi tted to each tank and
a non-return fl ap on the overall supply pipe.
• If the pressure of the distribution network exceeds 5 bar, a pressure reducer must be fi tted
to the overall supply pipe.
• For operation with a hot water output temperature above 60°C, ensure the installation
EN
complies with the regulations in force. A thermostatic mixer valve may be necessary to
obtain an acceptable temperature at the tap (50°C).
• If metal piping is used, use a cast-iron sleeve or a dielectric pipe joint (brass connectors
are prohibited).
