Connecting the Piston Backflushing
The piston backflushing removes salts and other substances from the area
behind the seals. To do this, connect a bottle with flushing solution to the
flush pump and to the pump head. The connection between pump head
and flush pump is preinstalled at the factory.
Functional principle The piston backflushing function automatically flushes the rear piston area
of the pump head upon switch-on and in continuous mode.

Upon switch-on: The rear piston area of the pump head is automatically
flushed for 30 seconds.

In continuous mode: The rear piston area of the pump head is flushed
automatically every 60 minutes, for 30 seconds.
Designation Inlet and outlet of the flush pump are located on the front of the device.
Flushing solution: These are suitable flushing solutions:

Water

Mixture of 80 % water and 20 % ethanol

Isopropanol
Note: KNAUER recommends the use of pure isopropanol as flushing solu-
tion for piston backflushing.
