ATTENTION
Counter-hold using a suitable tool (e.g. pipe wrench) during connection of the heat exchang-
ers in order to avoid damage.
Install pipes and connections in such a way that the heat exchangers remain freely accessible
for maintenance.
Maximum working pressure: 16 bar
Maximum hot water flow temperature: 120 °C
Valves and actuators must be installed professionally. Please note here whether a version with a 2-way or 3-way
valve is to be implemented.
For the electrical connection of the actuator, see the circuit diagram.
