Steps to connect /replace a gas cylinder Steps to connect /replace a Steps to connect /replace a Steps to connect /replace a
1. Close the main valve on the gas cylinder.
2. Depressurize the connected gas pipeline.
3. Remove all equipment from the cylinder connector.
4. Close the connection thread on the valve with the screw cover.
5. Place the protective cap onto the gas cylinder and screw it tight.
6. Release the anti-tipping device and remove the gas cylinder.
7. Replace the cylinder with a new/different one.
8. Secure the new cylinder to prevent it tipping over and unscrew the protective cap.
9. Ensure that the main valve on the cylinder is closed. Only then remove the screw
cover (blind plug) from the valve connector.
Reconnect the equipment you removed in step 3 to the valve connector on the gas
10.
cylinder. Do not apply any oil or grease to the thread.
11. Ensure that the reconnected controls are closed.
Ensure that gas can flow in the parts you wish to flush. For this purpose, disconnect
12. the pipeline immediately upstream of the device while the gas cylinder is closed.
Ensure that the flushing gas is discharged safely (via a flow indicator).
13. Now slowly open the main valve on the gas cylinder.
14. Adjust the gas flow. Do not exceed the maximum pressure levels.
15. Now close the main valve on the gas cylinder again.
If the outlet pressure of the high-pressure reducer or cylinder pressure regulator has
16.
fallen almost to 0 MPa, open the gas cylinder briefly and then close it again.
Repeat the procedure described above several times to ensure that there is no more air
17. in the dead space of the regulator and the pipeline. Everything will be flushed after a
total of 5 filling and emptying cycles.
18. After the flushing cycle, reconnect the pipe to the appropriate gas inlet on the device.
Open the main valve on the gas cylinder. Set the outlet pressure to the operating
19.
pressure recommended in section 1 of the User Manual.
20. Carefully check the tightness by means of a tightness test.
