Perform a function check before each use, but in any case at least every 6 months.
Warning!

5.2 Performing the function check

1. Check the distributor for visible mechanical damage.
2. Ensure that the click dials of the flowmeters are in position "0".
3. Connect the distributor to an oxygen cylinder using a pressure tube.
4. Check that the connections between the distributor, the pressure tube and the oxygen
cylinder are tight.
5. Slowly open the cylinder valve.
6. Now use the click dials to adjust all dial positions one after the other and in each case
check at the oxygen outlet whether the flow is rising in accordance with the setting.
7. Return the click dials to setting "0".
8. Check that the screwed connections on the distributor are tight.
9. Prepare a soap-and-water solution using perfume-free soap.
