9.5 Changing the sample volume
To change the sample volume, change the Dose time with parameter
DoseT. To increase the sample volume, lengthen the dose time.
Beware: Changing the suction hose length or diameter will change the
suction velocity, which changes the sample volume as well.
9.6 Maintenance
Be aware! Remove power supply, compressed air supply and medium
pressure before maintenance or reparations.
Maintenance and reparations should be done by qualified personnel.
Avoid direct contact with wastewater / medium. Wear protective gloves
during use, maintenance and reparation of the sampler.
Be aware! When removing the inlet or outlet from the enclosure the
danger of fingers entering the sample bullet occurs. This can cause
serious injuries.
Points of attention
-
Clean the interior of the pump, piping and coupling (all wetted
parts) with a soft brush and tap water, on a regular basis. The
interval depends on the sampled medium.
- Replace suction hose if necessary.
- Check condition of the tubing inside the pump, replace when
necessary.
