5.2 Operating the sample gas pump

CAUTION
Risk of injury by moving parts
The device may be damaged if it falls down of by impacts. Pay
attention to any accessible moving parts.
Operation without cover or with damaged cover is not al-
lowed!
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 0.3 is not allowed. The gas outlet must
not be closed. The flow rate must be at least 50 l/h (150 l/h
with system pressure 0.3 bar). If the flow rate continuously is
throttled below 150 l/h during operation, the flow rate must
be controlled with a bypass valve.
NOTICE
Extreme throttling reduces the life time of the bellow.
If the pump is equipped with a bypass valve, the flow rate can
be adjusted. Do not apply force when turning the valve, be-
cause the valve may be damaged otherwise! The turning
range of the valve is about 5 turns.
