Maintenance
The apparatus should be cleaned regularly in accordance with the degree of contamination present. In
view of the quality of samples, we recommend to clean thoroughly especially the wetted parts like
dosing unit, electrodes, distributor, bottles and inlet hose.
Remark:
There is a health hazard if the device is used in biologically or chemically contaminated areas. Please
take the necessary precautionary measures when cleaning or servicing the device.
Attention:
Disconnect the power connections before carrying out any maintenance or repair works. Repair works
must only be carried out by specially trained and authorised service personnel.
Remark: For cleaning of the metering vessel: see chapter „Operation – sampling systems“.
Pumping capacity:
The pumping capacity (patented method) can be adjusted in the
service menu between 70 and 100 %.
Remark:
The adjusted pumping capacity has no effect on the suction height
but only on the average suction speed when extracting the
sample. The lower the pumping capacity, the longer the life of the
pump
