5. To find out how to connect the device that you want to supply with oxygen, please con-
sult the operating instructions for the relevant device.
3.2 Disconnecting pressure reducer
1. Close the oxygen cylinder valve.
2. Release the pressure in the system, e.g. by switching a connected device on and then
off or by opening a shut-off valve.
While the system is under pressure, the sealing ring is pressed into the wedge-shaped
circular gap between the oxygen cylinder valve and connecting union 2. For this reason
it is impossible to remove the pressure reducer under pressure.
3. Unscrew the union nut 2 by hand.
