Installation
1. Remove cylinder valve plastic dust seal. Clean the cylinder valve outlet of impurities that may clog
orifices and damage seats before connecting the regulator/flowmeter.
Crack the valve (open then close) momentarily, pointing the outlet away from people and sources of
ignition. Wipe with a clean lint free cloth.
2. Match regulator/flowmeter to cylinder. Before connecting, check that the regulator/flowmeter label
and cylinder marking agree and that the regulator/flowmeter inlet and cylinder outlet match. NEVER
CONNECT a regulator/flowmeter designed for a particular gas or gases to a cylinder containing any
other gas.
3. Connect the regulator/flowmeter inlet connection to cylinder or pipeline and tighten it firmly but not
excessively, with a suitable spanner.
4. Connect and tighten the outlet hose firmly and attach down-stream equipment.
5. To protect sensitive down-stream equipment a separate safety device may be necessary if the regulator/
flowmeter is not fitted with a pressure relief device.
Operation
With the regulator/flowmeter connected to cylinder or pipeline, and the adjustment screw/knob fully disengaged,
pressurize as follows:
1. Stand to one side of regulator/flowmeter and slowly open the cylinder valve. If opened quickly, a sudden
pressure surge may damage internal regulator/flowmeter parts.
2. With valves on downstream equipment closed, adjust regulator/flowmeter to approximate working
pressure. It is recommended that testing for leaks at the regulator/flowmeter connection points be
carried out using a suitable leak detection solution or soapy water.
3. Purge air or other unwanted welding grade shielding gas from equipment connected to the regulator/
flowmeter by individually opening then closing the equipment control valves. Complete purging may
take up to ten seconds or more, depending upon the length and size of the hose being purged.
