Manual 0-5420 3-5 INSTALLATION, OPERATION AND SETUP
!
WARNING
DO NOT tamper with the relief valve or
remove it from the flowmeter/ regulator.
!
WARNING
Stand to the side of the cylinder opposite
the flowmeter/ regulator when open-
ing the cylinder valve. Keep the cylinder
valve between you and the flowmeter/
regulator. For your safety, NEVER STAND
IN FRONT OF OR BEHIND A FLOWMETER/
REGULATOR WHEN OPENING THE CYLIN-
DER VALVE!
8. Slowly and carefully open the cylinder valve (Figure
3-3) until the maximum pressure shows on the high
pressure gauge.
Art # A-09828
Figure 3-3: Open Cylinder Valve
9. On all cylinders, open the valve completely to seal the
valve packing. On gaugeless flowmeters/ regulators,
the indicator will register the cylinder contents open.
!
CAUTION
Keep the cylinder valve wrench, if one is
required, on the cylinder valve to turn OFF
the cylinder quickly, if necessary.
10. Attach the desired downstream equipment.
3.07 Leak Testing the System
Leak test the system before putting into operation.
1. Be sure that there is a valve in the downstream equip-
ment to turn off the gas flow.
2. With the cylinder valve open, adjust the Flowmeter/
regulator to deliver the maximum required delivery
pressure.
3. Close the cylinder valve.
4. Turn the adjusting screw/knob counterclockwise one
turn.
a) If the high-pressure gauge reading drops, there is
a leak in the cylinder valve, inlet fitting, or high-
pressure gauge.
b) If the low-pressure gauge drops, there is a leak
in the down stream equipment, hose, hose fitting,
outlet fitting or low-pressure gauge. Check for
leaks using an approved leak detector solution.
c) If the high-pressure gauge drops and the low-
pressure gauge increases at the same time, there
is a leak in the flowmeter/ regulator seat.
d) If the flowmeter/ regulator requires service or
repair, take it to a qualified repair technician.
5. Once leak testing has been performed and there are
no leaks in the system, slowly open the cylinder valve
and proceed.
!
WARNING
If a leak has been detected anywhere in
the system, dis continue use and have
the system repaired. DO NOT use leaking
equipment. Do not attempt to repair a
leaking system while the system is under
pressure.
3.08 When You Finish Using the
Flowmeter/ Regulator
1. Close the cylinder valve.
2. Open the valve on the downstream equipment. This
drains all pressure from the system.
3. Close the valve on the downstream equipment.
4. Turn the adjusting screw counterclockwise to release
the ten sion on the adjusting spring.
5. Check the gauges after a few minutes for verification
that the cylinder valve is closed completely.
3.09 Storage of the Flowmeter/ Regulator
When the regulator is not in use and has been removed from
the cylinder, it should be stored in an area where it will be pro-
tected from dust, oil, and grease. The inlet and outlet should be
capped to protect against internal contamination and prevent
insects from nesting.
