7.1 Return shipment to the manufacturer
Due to legal requirements placed on environmental protection and occupational safety and health and to

and hazardous substances. That also applies to cavities in the devices. If necessary, the customer must neut-
ralise or purge the unit before return to PKP.
Costs incurred due to inadequate cleaning of the device and possible costs for disposal and/or personal injur-
ies will be billed to the operating company.
WARNING! Risk of injury due to insufficient cleaning!
The operating company is responsible for all damages and harm of any kind, in particular physical
injuries (e.g. caustic burns or toxic contaminations), decontamination measures, disposal etc. that
can be attributed to insufficient cleaning of the measuring instrument.
Comply with the instructions below before returning the unit.
The following measures must be taken before you send the unit to PKP for repair:
Clean the device thoroughly. This is of extreme importance if the medium is hazardous to health, i.e.
caustic, toxic, carcinogenic or radioactive etc.
Remove all residues of the media and pay special attention to sealing grooves and slits.
Attach a note describing the malfunction, state the application field and the chemical/physical properties
of the media.
