III. OPERATION
3.1 PREPARING FOR OPERATION
Once installation of equipment has been completed, (see II INSTALLATION) prepare for
operation as follows:
A.
Observe precautions in SAFETY Section.
B. Before pressurizing an oxygen regulator, make sure it has been drained of residual gas.
C. While standing off to one side, open the cylinder or upstream valve. The cylinder valve
should be opened slowly to avoid a sudden pressure surge in the regulator.
D. Slowly turn adjusting knob clockwise until the outlet gauge indicates the desired
pressure.
E. To reduce pressure, allow gas to discharge from equipment towards a safe area, and
turn adjusting knob counter clockwise, until desired pressure is indicated on the gauge.
Close gas control valve on equipment.
F.
Prior to lighting torch, purge gas line by opening equipment discharge valves and closing
them after purging is complete. (Adequate purging time depends on length and size of
hose). if more than one regulator is used, close one valve before opening next one to
avoid unsafe or unwanted mixture of gases.
CAUTION
Do not purge oxidizing or fl ammable gases in the presence of fl ame, lit cigarettes, or
other sources of ignition, or towards person.
G. Test connections with soap solution (see SAFETY Section; item 0). If no bubbles
appear, system is ready to use.
3.2 SHUTTING DOWN
Close cylinder valve whenever the regulator is not in use. To shut down for extended periods
(more than 30 minutes):
A Close cylinder or upstream valve.
B. Open downstream valve to purge the line towards a safe area.
C. After gas is drained completely, release adjusting knob and close downstream valve.
