• Connect the sensor element of the safety temperature limiter with the
heating element.
• Reconnect the electrical connections.
• Measure the current during a test run in order to check the power
consumption of the heating.
Checking the functionality of the safety temperature limiter
The switching point is approx. 170 °C. It is not necessary to measure the
temperature.
• Pull out the safety temperature limiter and heat it to ensure that it
triggers (e.g. with a hot air gun).
Manual emptying of the steam generator
• Switch off the device.
• Open the manual drain tap (BV1) with a maximum pressure of 120 kPa
in the steam generator.
• When the steam generator has cooled down and is depressurised,
disconnect the hose connections to the pressure transducer (PS1).
• After emptying: Close the drain tap again and reattach the hose
connection to the pressure transducer.
3.9 Safety valves
3.9.1 Position and function
Both the steam generator (X series only) and the sterilisation chamber are
protected from overloading by safety valves.
