Slowly open the cylinder valve (1), ensure that the cylinder pressure is showing on the
content´s gauge (3), open the downstream (blowpipe) valve, and with the pressure
adjusting knob (5) rotate clockwise to set the required working pressure using the outlet
gauge (4).
5. Closing Down the Cylinder Pressure Regulator
5.1 Prolonged interruption.
Close cylinder valve (1), unwind (anti-clockwise) the pressure adjusting knob (5), vent the
pressure in the system by opening the downstream (blowpipe) valves. Once the system
has been purged, close the downstream valves.
6. Operation and Maintenance Instructions
6.1 Protect the cylinder pressure regulator from damage. Check visually for any signs of
damage regularly.
6.2 The preset adjustment of the safety valve (7) must not be changed.
6.3 Ensure that all gaskets, O-rings, and mating surfaces are in a satisfactory condition.
6.4 If it is suspected that the cylinder pressure regulator is not functioning correctly, or is
found to have any form of leakage, close the cylinder valve and remove from service
immediately.
Do not under any circumstances undertake, or allow any repairs by unauthorised personnel.
7. Repairs
7.1 Repairs of cylinder pressure regulators shall be carried out by competent personnel at
an authorised service or repair workshop. Only original spares may be used.
7.2 Repairs or modifications carried out by the user or a non-authorised third party will
entail loss of liability.
8. Cylinder Pressure Regulators with Flowmeter Gauge
Paragraphs 1 to 7 of these Operating Instructions applies also to cylinder pressure regulators
with flow gauge. The flow set by the pressure adjusting knob (5) may be read at the flow-
meter gauge (4). If the apparatus or equipment to be used downstream also has a flowmeter
device, please remove it as it will not be calibrated with the cylinder pressure regulator.
