Screw tailpipe / high pressure hose from cylinders or cylinder bundle / collecting branch onto
the inlet connection on the manifold. Ensure that the shut-off valve (B) and the purge valve (C)
are in the closed position.
Open one cylinder from bank SLOWLY.
Check connection between tailpipe and
inlet connection for leaks using a 0.5%
EN
teepol / water solution.
If no leaks open remaining cylinders slowly
from that bank.
Note: if a leak occurs between tailpipe/
high pressure hose/collecting branch and
inlet connection check to see if sealing
washer is fi tted correctly or missing.

Check that shut off valve B is closed.
•
Check that purge valve C is closed.
•
Open valve B and the manifold is ready to supply gas at 7 bar through the outlet connection
•
F. The cylinder pressure can be read on the inlet gauge D and the outlet pressure on gauge
E.
Check all connection for leaks using a 0.5% teepol / water solution.
•
