WARNING
DO NOT use a regulator that delivers pressure exceeding the pressure rating of the downstream
equipment unless pro visions are made to prevent over-pressurization (i.e. system relief valve). Make
sure the pressure rating of the down stream equipment is compatible with the maximum delivery
pressure of the regulator.
4. Be sure that the regulator has the correct pressure rating and gas service for the cylinder used.
5. Carefully inspect the regulator for damaged threads, dirt, dust, grease, oil, or other flammable substances.
Remove dust and dirt with a clean cloth. Be sure the inlet swivel filter is clean and in place. Attach the
regulator (Figure 3-9) to the cylinder valve. Tighten securely with a wrench.
!
WARNING
DO NOT attach or use the regulator if oil, grease, flamma ble substances or damage is present! Have a
qualified repair technician clean the regulator or repair any damage.

6. Before opening the cylinder valve, turn the regulator adjusting screw counterclockwise until there is no
pressure on the adjusting spring and the screw turns freely.
7. Relief Valve (where provided): The relief valve is designed to protect the low pressure side of the regulator
from high pres sures. Relief valves are not intended to protect down stream equipment from high pressures.
!
WARNING
DO NOT tamper with the relief valve or remove it from the regulator.
!
WARNING
Stand to the side of the cylinder opposite the regulator when opening the cylinder valve. Keep the
cylinder valve between you and the regulator. For your safety, NEVER STAND IN FRONT OF OR BEHIND
A REGULATOR WHEN OPENING THE CYLINDER VALVE!
8. Slowly and carefully open the cylinder valve (Figure 3-9) until the maximum pressure shows on the high
pressure gauge.
