2.3 Before connecting a sample line to the Isolation valve at the gas source, first check that
the gas to be sampled is free from excessive moisture and/or particle contaminants by
placing a white filter paper (or similar) approximately 1 cm from the outlet and very
slowly and carefully opening the Isolation Valve to achieve a steady flow of gas/air onto
the white filter paper for approximately 1 minute. See Fig 6.
Fig 6.
Isolation Valve Test
If contaminants are seen on the white filter paper, a filter unit must be installed at the
Isolation Valve outlet and before the sample hose.
When the filter unit is fitted, repeat the above procedure with the white filter cloth.
