WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious injuries.
Please ensure when handling hazardous substances
that you have read the latest safety data sheets provided
by the manufacture of the hazardous substance. The
actions required are described in the safety data sheet.
Check the safety data sheet regularly and replace, if
necessary, 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 workstations affected.
During decommissioning, de-energise the mains cable
and ensure that it cannot be switched on again.
Thoroughly clean the metering system of chemicals 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. Com‐
pressed 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 suitable
medium.
4.
Also read the operating instructions for the indi‐
vidual components used.
Comply with the storage conditions for temporary decommissioning.
