Functional check
3. Open the cylinder valve
slowly
.
You can now read the cylinder pressure on the pressure
reducer's gauge. A reading of 200 bar means that the
cylinder is full, a reading of 100 bar that it is half full.
You should change the cylinder in good time, e.g.
when the pressure falls below 50 bar, to ensure a
sufficiently long operating time.
4. Close the cylinder valve again.
5. Observe the gauge's needle on the pressure reducer for
approx. 1 minute.
If the position of the needle stays constant, the system
is free from leaks.
If the needle falls steadily, there is a leak in the system.
Rectifying leaks
Note:
We recommend you keep a stock of replacement seals for the connectors (see also
the OXYWAY instruction manual).
1. Prepare a soapy solution using unperfumed soap.
2. Wet all the screw and hose connections with the solution. If bubbles form, this
indicates a leak.
3. Close the cylinder valve.
4. Depressurize the system by opening a dosage unit until the pressure falls to 0 bar.
Warning!
The screwed unions of the oxygen lines must be tightened only by hand.
5. In the event of leaks, replace the damaged parts (see the instruction manual for the
unit).
6. Check for leaks again, as described above.
7. If the leak cannot be rectified, the unit must be repaired. Send the box to your
authorized dealer or the manufacturer for repair.
