Be sure to observe any varying information in the rating
plate. The conditions at the site must correspond with
all rating plate information.
5 Operation and control
5.1 Switching the sample gas pump on
When switching the sample gas pump on make
sure that
• no abnormal sounds or vibrations occur.
• the flow rate is neither too low nor too high. This
would indicate a cracked bellow.
5.2 Operating the sample gas pump
The sample gas pump is suitable for delivering gases
only. It is not suitable for liquids.
The sample gas pump should be operated without
pressure. A system pressure above 0.5 bar is not al-
lowed. The gas outlet must not be closed. The min-
imum flow rate must be 50 l/h. If a throttle of a gas
pump is under 150 l/h in continuous operation, the flow
rate must be adjusted by a bypass valve. In this case,
pump type "PTFE with bypass valve“ should be used.
If the pump is equipped with a bypass valve, the flow
rate can be adjusted. Do not apply force when turning
the valve, because the valve may be damaged other-
wise! The turning range of the valve is about 7 turns.

regulations when performing any type of maintenance.
