Pressure regulators are precision manufactured instruments which, with correct use will provide reliable and trouble free service.
Check that the cylinder socket and the regulator connections are free from oil, grease and damage. Open the cylinder valve momentarily to eject any water or foreign matter form the seating (Except in the case of hydrogen). Ensure that the blast is not directed at persons or naked flames.
Connect the regulator to the cylinder valve (left hand for acetylene and other combustible gases). Right hand for oxygen and others non-combustible gases, using the correct spanner and ensure a gas tight seal. check that the pressure adjusting screw of the regulator is fully released.
Connect downstream equipment and open the cylinder valve slowly.
Check all joints for leaks using a 0.5% Teepol in Water Solunon. The contacts of the cylinder will register on the cylinder contact gauge and will decrease to zero as the cylinder empues. The contents are shown in baslbf/m2 (1 bar x 14.5 ibf/m2), To set pressure, screw the pressure. adjusting knob clockwise until the required outlet pressure registers on the outlet gauge, when gas is flowing, there may be a reduction in pressure and adjustments be made purge the gas line before lighting the equipment.
When work has stopped, close the cylinder valve, venl gas form gas the hoses and unscrew the pressure adjusting knob.
