Warning
In the event of a possible blockage of a drive, the mains plug must be
pulled out of the socket immediately. Do not attempt to free jummed
sample vessels or other parts while the instrument is switched on. Block-
ages can only be cleared when the instrument is in a voltage-free status;
this action generally involves a considerable risk of injury.
Warning
The 843 Pump Station is not suitable for usage in biochemical, biological
or medical environments in its basic equipment version.
Appropriate protective measures must be implemented in the event that
potentially infectious samples or reagents are being processed.

The electrical safety when working with the instrument is ensured as part of
the international standard IEC 61010.
Warning
Only personnel qualified by Metrohm are authorized to carry out service
work on electronic components.
Warning
Never open the housing of the instrument. The instrument could be dam-
aged by this. There is also a risk of serious injury if live components are
touched.
There are no parts inside the housing which can be serviced or replaced
by the user.

An incorrect mains voltage can damage the instrument.
