SAFETY/INSTALLATION 3-8 Manual 0-5450
!
WARNING
DO NOT
use a regulator that delivers pressure exceeding the pressure rating of the downstream equip-
ment 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 3-6) 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 REGULA-
TOR WHEN OPENING THE CYLINDER VALVE!
8. Slowly and carefully open the cylinder valve (Figure 3-7) until the maximum pressure shows on the high pressure gauge.
