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.
