Operation
Proper operation is only possible if the thermometer ball valves and the ball
valves are open (0° setting).
For safety reasons, liquid must be able to escape via the discharge line of the
diaphragm safety valve during heating.
1. If the diaphragm safety valve has responded, check the system.
2. Remove the cause before recommissioning the system.
