filtering may be required where the sample is heavily contaminated with water
(available from LANDTEC, see part number GA3KP.S15 in section
BIOGAS 3000
Consumable Products ).
Care should be taken in routing the drain line, especially in cold environments.
The drain line may need insulating or even trace heating to prevent freezing of
water within the pipe. This is not part of the BIOGAS 3000 system and is the
responsibility of the operator.
Alternatively, the contents can be emptied in to a suitable container and
disposed of in a safe manner.
If the auto-drain option is fitted, no manual draining of the system is required.

The drain line should be connected to the bulkhead connector labelled
‘DRAIN’ – see annotation 8 on

connections .

The drain line should be run to a position where it is safe to discharge
the small amount of liquid that is removed from the sample gas.

The contents of the catchpot are drained under gravity. Therefore, any
tubing needs to be lower than the drain compression fitting.

The drain connection on the system is a 6mm stainless steel bulkhead
connector with a compression fitting suitable for 6mm outer diameter
tubing. It is recommended that stainless steel tubing be used where
possible.

The catchpot contains a liquid level (reed) switch. When the liquid
reaches a certain level, the switch activates and informs the BIOGAS
3000 module. From here, an icon is displayed on screen and if
configured triggers a relay (see
Configure Relays ).

Refer to the Emptying the Catchpot section of this operating manual for
how to drain the catchpot.

When taking a gas sample, ensure the drain ball valve (see annotation 9
