5. MAINTENANCE

5.1 Cleanliness
Ensure that the cleanliness of this product is maintained. In order to do this :
Regularly clean the outside of the pressure reducer with lint-free cloth and alcohol (all other
cleaning methods are prohibited).
The indicator pressure of gauges may have incompatibilities with isopropyl alcohol. When cleaning
these, use ethyl alcohol (ethanol).
The inside of the pressure reducer must not be cleaned (this operation is carried out at the factory).
However, it is recommended to flush the pressure reducer with a neutral gas before putting it into
service, or after a long storage period.
5.2 Checks
Each time the cylinder is changed:
Check that the pressure reducer shows no visible signs of damage.
Clean the pressure reducer using the procedure described above.
After each assembly, check that the regulator operates correctly.
The correct operation of the pressure reducer is to be regularly checked by the user (at least once a
month). In case of doubt or incorrect operation, replace the pressure reducer by a new one. A pressure
reducer that has discharged an excessive flow must be replaced.
