!
WARNING
DO NOT attach or use the Flowmeter/Regulator
if oil, grease, flamma ble substances or damage
is present! Have a qualified repair technician
clean the Flowmeter/Regulator or repair any
damage.

Valve
7. Before opening the cylinder valve, turn the
Flowmeter/Regulator adjusting screw
counterclockwise until there is no pressure on
the adjusting spring and the screw turns freely.
8. Relief Valve (where provided): The relief valve is
designed to protect the low pressure side of the
Flowmeter/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 Flowmeter/Regulator.
!
WARNING
Stand to the side of the cylinder opposite
the Flowmeter/Regulator when opening
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 CYLINDER VALVE!
9. Slowly and carefully open the cylinder valve
(Figure 3-6) until the maximum pressure shows
on the high pressure gauge.

10. On all cylinders, except acetylene, open the valve
completely to seal the valve packing. On gaugeless
Flowmeter/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.
12. Attach the desired downstream equipment.
3.09 Leak Testing the System
Leak test the system before putting into operation.
1. Be sure that there is a valve in the downstream
equipment 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 detec-
tor 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.
