4. DO NOT use the regulator/flowmeter as a control valve. When downstream equipment is not in use for
extended periods of time, shut off the gas at the cylinder valve and release the gas from the equipment.
5. OPEN the cylinder valve SLOWLY. Close after use.
User Responsibilities
This equipment will perform safely and reliably only when installed, operated and maintained, and repaired in
accordance with the instructions provided. Equipment must be checked periodically and repaired, replaced,
or reset as necessary for continued safe and reliable performance. Defective equipment should not be used.
Parts that are broken, missing, obviously worn, distorted, or contaminated should be replaced immediately.
The user of this equipment will generally have the sole responsibility for any malfunction, which results from
improper use, faulty maintenance, or by repair by anyone other than an accredited repairer.
CAUTION
! !
Match regulator/flowmeter to cylinder. NEVER CONNECT a regulator/flowmeter designed for a particular gas or gases to
a cylinder containing any other gas.
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 the hose to the welding machine with a suitable
hose clamp. Ensure no gas leakage. The flowmeter must be in the vertical position to read accurately.
5. The regulator/flowmeter has a self-reseating relief valve – not designed to protect down stream
equipment. To protect sensitive down-stream equipment a separate safety device may be necessary.
Operation
With the regulator/flowmeter connected to cylinder or pipeline:
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.
