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 exces-
sively, 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/ flow-
meter is not fitted with a pressure relief device.
