Firepower MST 180i

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
equipment to turn OFF the gas flow.
2. With the cylinder valve open, adjust the 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 regulator seat.
d) If the 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.
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.

WARNING

3.08 When You Finish Using the 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 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.
