cylinder and secondary pressure regulators
7. Start-up.
Danger
Before starting operation, check whether the pressure device to be used is suitable for
the planned application purpose (type of gas, pressure, material, etc.)
Warning
Before switching on the pressure device ensure that no one can be endangered by
starting operation of the pressure device.
Preparation
Ensure that all fittings and connections are tightly connected. Turn the hand-wheel of the regulator in an anti-
clockwise direction until the end stop - this means that the gas flow is now stopped. Close all valves.
Process gas extraction
Slowly open the cylinder valve (shut-off valve on the pressurized gas container). Watch the inlet pressure
gauge. Adjust the required outlet pressure by turning the regulator hand-wheel clockwise. Adjust the required
flow on the regulating valve (if applicable).
8. Cylinder change.
Danger
When changing the cylinder used with toxic, corrosive, or hazardous gases, the appro-
priate protection measures are to be taken to protect personnel (breathing apparatus,
eye protection and protective clothing as appropriate or required). Maximum permis-
sible values of the concentration at the place of work must not be exceeded! Purge,
vent, and or dispose of the residual gas contents of all toxic, corrosive, and hazardous
gases in a safe and environmentally appropriate manner in accordance with local
regulations.
Preparation
Tightly close the cylinder valve (on the pressurized gas container). Close the inlet valve on the regulator if so
equipped. Completely empty the regulator. The pointers of the inlet pressure and outlet pressure gauges should
indicate no internal pressure. Turn the hand-wheel of the regulator anticlockwise until the end stop (flow
closed). Close the outlet valve.
Removal from cylinder
Using a suitable fork spanner, loosen the swivel nut from the cylinder valve connection. Pay attention that
some connections are right-hand or left-hand threads. Support the regulator during removal. If escaping gas is
noticed, reconnect the swivel nut and repeat the Preparation instructions again, making sure that the cylinder
valve is closed.
