5.2 Operating the sample gas pump
DANGER Toxic, corrosive gases
The measuring gas led through the equipment can be hazardous when breathing or
touching it.
a) Check tightness of the measuring system before putting it into operation.
b) Take care that harmful gases are exhausted to a save place.
c) Before maintenance turn off the gas supply and make sure that it cannot be turned
on unintentionally.
d) Protect yourself during maintenance against toxic / corrosive gases. Use suitable pro-
tective equipment.
The pump will only run after reaching the block temperature. It is only intended to convey gaseous mediums. It is not suitable
for liquids.
Operation under primary pressure is prohibited. The flow inside the device (operational regulation via flow meter with built-in
needle valve) should always be at least 50 L/h. Throttling greatly will shorten the life of the sample gas pump.
