Care and Maintenance

Replacement parts are available on request. If you notice something wrong in the
regulator, which cannot be repaired following these instructions, send it back to
your distributor.
•
Do not clean the gauges glasses with petrol, solvents or detergents of any type.
Malfunctionings
- In case of malfunctioning (for ex. leaks from the gauges or from the safety valve), stop
using the pressure regulator and immediately close the bottle valve.
- If no damage can be seen on the outside of the regulator, we suggest to send it back to
your distributor, so that it can be checked and repaired.
Do not use the pressure regulator if there are the following malfunctionings
- The seal gaskets used for the connection to the bottle are damaged or missing.
- The regulator or some of its parts (gauge, input or output connection) are damaged or
contaminated by dirt.
- Joints are leaking.
- The safety valve regulation has been modified or gas is coming out of the valve.
Safety valve
For safety reasons, the pressure regulator is equipped with an overpressure valve.
In case of functioning defects, this valve lets the excess gas pressure flow towards the outside.
It is absolutely forbidden to modify the safety valve calibration!
Tightness check
- To check the pressure regulator tightness, operate in the open air with soapy water or with
special detectors.
- Spray the detector on the area that must be checked.
- The detection of gas leaks is enhanced by the forming of bubbles or foam.
