• Open the output control valve (4) and open the ball valve (9) on the leak testing
gauge assembly for the nitrogen to flow into the system.
(If using a manifold, open the output control valve (4) and the low side valve
(13) on the manifold.)
• Make sure the required pressure is available on both gauges. (You may need to
turn the T handle (6) on the regulator to adjust to the required pressure.)
• Once the pressure is equalized (make sure the black needle is aligned with the
red marker on the leak testing gauge assembly) close the ball valve
connection (9).
(If using a manifold, close the low side valve (13) on the manifold making note
of the pressure when the valve is closed.)
• Close the output control valve (4) on the regulator
• Disassemble the yelllow charging hose (11) from the regulator and leave the
system for a period of time (time is based on the size of the system.)
• After some time, look at the gauge, if there is a leak in the system the pressure
will have dropped from the original settting.
REGULATOR REMOVAL
• Turn the cylinder valve off.
• Relieve the pressure on the regulator by opening the output control valve (4).
Both gauges should read zero.
• Slowly loosen the cylinder connection. There may still be some pressure
between the regulator and cylinder.
• Completely remove the regulator.
• Clean and store the regulator in its box to prevent damage.
