FUNCTION CHECK
The excess flow device SBS must be tested for functionality as follows:
Risk of injuries or fire!
Serious burns to the skin or damage to property.
Do not use an open flame to check for leaks!
1. Close the gas cylinder valve.
2. Detach the hose line from the consumer.
3. Use your thumb to close the hose line opening.
4. Slowly open the gas cylinder valve.
5. Hold pressed the knob of the excess flow device SBS for three seconds:
 excess flow device SBS is activated.
6. Remove your thumb from the end of the hose line:
 the excess flow device SBS responds, a “PLOP” sound can be heard,
 the gas supply is interrupted and only a small residual amount can escape from the
hose line.
7. Connect the hose line to the consumer.
8. Open the gas cylinder valve and perform LEAK TESTING.
Item 5 is not applicable to the automatic SBS, since it opens automatically after some
time.
