1. FUNCTION
2.1 Connection of the Pressure Regulator
Check that the pressure regulator is correct both for the type of gas and the pressure in
the cylinder in use.
Turn the pressure adjusting screw (6) anticlockwise, to check that the pressure regulator
valve is closed.
Replace the "O" ring (2) if it is damaged every time you change the cylinder.
Before screwing on the pressure regulator, briefly open the cylinder valve (1) then close
to remove any impurity, in case using compressed air. Pay attention to direct the cylinder
outlet towards a wall and far from heating sources.
During this operation it is dangerous to stand, or place your hands in front of the
cylinder valve (1).
Position the pressure regulator with the gauges the right way up.
Screw the inlet connection (3) tightly to the cylinder valve, by hand or by using a spanner.
3.1 Opening
Slowly open the cylinder valve (1). The high pressure gauge (4) will show you the
cylinder pressure.
Opening the cylinder valve too quickly may make gauges malfunction.
Open the pressure adjusting screw (6) very slowly. The low pressure gauge (5) will show
the outlet pressure.
CAUTIONS
Incorrect use of the pressure regulator can cause serious damage. Users must
be trained by competent people.
The pressure regulator must be treated as a precision instrument. Protect it from
accidental knocks, dust, oil and other sources of dirt.
Do not use the pressure regulator if it is not in perfect working condition (see 5.1).
When you draw gas, the cylinder must be placed upright and protected from falling.
