• Connect the filling hose of the gas-filling device (gas cylinder with
pressure-reducing valve or gas handling cart) to the central
supply connection (type DILO DN8 coupling).
• Fill the circuit breaker gradually until rated pressure is reached.
Never set the pressure-reducing valve higher than the rated
breaker pressure.
• After a temperature equalization period of approximately 1 hour,
check the gas pressure again and correct it, if necessary.
• Check all gas piping seals for leaks using a leak detector.
• Screw on the protective cap for the central supply connection.
