Dispose of the regulator in accordance with local requirements.
Do not clean gauge glasses with petrol, solvents or any other kind of detergent.
5.1 Malfunctioning
In case of malfunction (e.g. leaks in the gauges or in the relief valves) stop use and close
the cylinder valve (1) immediately.
Unless there is visible damage to the outside of the instrument, we suggest that the
pressure regulator be returned to the supplier to be checked and repaired.
CAUTIONS
Do not use the pressure regulator if there are the following malfunctions:
The "O" ring (2) is damaged or lost.
The pressure regulator or any of its parts (gauge, inlet connection, outlet
connection) are damaged or dirty, oily etc.
There are any leaky connections.
The relief valve adjustment has been modified or the valve leaks.
5.2 Relief Valve
For safety reasons, the pressure regulator is equipped with an excess pressure valve.
In case of malfunctioning, this valve allows the excess gas pressure to vent.
CAUTIONS
Do not modify the calibration of the relief valve.
5.3 Checking The Seal
This check must be carried out only in the open air: use either soapy water or a gas leak
detector (Gas Control Part No: OTLDS). Do not use flames.
Spray detector on the area to be checked.
The forming of bubbles or foam is a sign of a leak.
