
The gas exhaust line should be connected to the bulkhead connector
labelled ‘PROCESS RETURN’ – see annotation 7 on

Air In
4.4.3
The air purge inlet requires uncontaminated air for the purge line. If
uncontaminated air is available, the particulate filter should remain in place.
If uncontaminated air cannot be guaranteed at the location of the analyser, the
particulate filter should be removed and a pipe should be connected in its
place and terminated at a point where uncontaminated air is present.

The sample tube should be connected to the bulkhead connector
labelled ‘AIR IN’ – see annotations 6 on

Vent to Atmosphere
4.4.4
Warning When performing an air purge the gas that was
previously sampled will be vented to atmosphere for a
short period, typically 10 seconds. This equates to
approximately 50ml of gas per air purge. In addition,
when performing a user calibration, the calibration gas
will be exhausted from this bulkhead. It is therefore
recommended that the ‘Vent to Atmosphere’ line should
be routed to a safe and well-ventilated area.

A ball valve should be incorporated in to the piping close to the BIOGAS
3000 system. This ball valve will be used as part of pressure testing the
system during routine maintenance.

The sample tube should be connected to the bulkhead connector
labelled ‘VENT TO ATMOSPHERE’ – see annotation 9 on

4.5 Drain
The system incorporates a catchpot and drain for removal of liquid to help
prevent water from entering the system (see annotation 6 on
