7. Remove the syringe from the silicone tubing, absorbing any liquid
that leaves the tubing with a tissue.
8. Route the free end of the tubing to the drain port outlet (see
Guiding Liquids to Waste ( } page 64) ).
9. Perform the above steps for all channels, including those that are
not used for the application.
If necessary, empty the syringe before starting the procedure for the
next channel.
10. When purging is complete, close the purge valve by turning the
valve knob clockwise.
NOTICE
Turn the valve knob only with your fingers. If the knob leaks, tighten a
little more. Be careful; overtightening may damage the purge valve
seals.
11. Empty the silicone tubing.
12. Dual pump only: If applicable, perform the purge procedure also for
the other pump.
Emptying the Silicone Tubing
NOTICE
Always empty the silicone tubing when purging is complete. When the
purge valve is closed, purge liquid remains in the tubing connected to
the purge outlet. Leaving the liquid in the tubing for a longer period
limits the tubing lifetime.
1. To absorb any liquid that might be leaving the purge outlet when the
tubing is removed, place the tissue under the outlet.
2. On the purge/sensor unit, remove the silicone tubing from the purge
outlet. The other end of the tubing remains in the purge drain port
outlet.
3. Hold the tubing so that any liquid that is present in the tubing flows
off through the drain port outlet.
4. On the purge/sensor unit, consider reconnecting the silicone tubing.
