WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
During decommissioning, de-energise the mains
cable and ensure that it cannot be switched on
again.
Thoroughly clean the metering system of chemi‐
cals and dirt when decommissioning it.
If the metering system is idle for a long period of time, thoroughly
rinse, clean and then drain all pipework, fittings, metering pump
and all other wetted parts. If possible, dry/flush the pipework with
compressed air. Compressed air can pressurise residue out of the
lines. When doing so, pay attention to the maximum permissible
pressure of the metering system.
Secure the metering system against unauthorised intervention.
Ensure that suitable barriers, such as flexible protective grating or
barrier tape, are in place.
1.
Disconnect the metering system from the mains power
supply.
2.
Depressurise all components of the metering system.
3.
Drain the metering system and thoroughly rinse it with a suit‐
able medium.
4.
Also read the operating instructions for the
individual components used.
Comply with the storage conditions for temporary decommis‐
sioning.
