to avoid risks and loss of production as well as enhance reliability and durability of
pressure control equipment.
5.3. These instructions must be kept permanently at hand in your workshop.
5.4.
Check that the cylinder valve connection is clean and undamaged; check that inlet
washer (9) of regulator (on N, P & H versions) is in good condition and in correct position.
Otherwise, clean & change washer if needed.
5.5. Connect the regulator gas tight by means of the sleeve nut (2) to the cylinder valve (1),
using spanner without excessive strength. The regulating screw (5) must show
downward.

corresponding to EN 3821 and hose connections to EN 560. Secure by appropriate hose
clamps.

the cylinder valve and SLOWLY open the cylinder valve (1). The HP gauge (3) will show the
gas contained in the cylinder. Adjust the required working pressure at the outlet gauge
or the flow at the flowmeter (4) by closing the regulating screw (5). Open a little bit the
shut off valve (6) and the valve of downstream equipment. Drop of pressure may be
compensated by auctioning the regulating screw.
