4.5. Purge and Vent Equipment
If required due to gas properties (such as for hazardous gases), install purge and vent valves to enable the
operator to remove hazardous gases from the lines using an inert purge gas before connecting and
disconnecting gas cylinders.
4.6. Initial Leak Test
Connect a nitrogen (or other appropriate gas) cylinder with a pressure regulator to both inlets on the
AK M80/86 manifold. Regulate the pressure to less than the manifold maximum inlet pressure and no
more than 90% of the inlet gauge maximum range.
Pressurize the manifold with nitrogen. Increase the line regulator to the maximum outlet.
Check all lines for leaks by listening for audible leakage and applying soap solution to NPT connections.
Disassemble, repair, and retest all leaks.
Disconnect the nitrogen cylinder.
Fully close (turn knob counterclockwise) the AK M80/86 line regulator.
