▶ The emptying is complete once the [Emptying complete] is displayed.
▶ The water circuit is emptied.
If the maximum water level of the tank is reached during emptying, the process
will stop, and the system outputs the message
[Tank overflow!] . In this case you
must let water out of the tank and then start emptying again. To do so, proceed as
follows:
5
Connect the supplied drainage tube to the tank drainage coupling.
6 Place a suitable container under the tank overflow to catch overflowing water.
If tubes are connected to both patient water circuits P1 and P2, then these can
only be emptied sequentially. To do so, proceed as follows:
7
Empty the first patient water circuit via the function [Empty tubes] and then
close the stopcock of this water circuit.
8 De-air the second patient water circuit so as to remove the air in the internal
tubing (⇨ "De-airing the Circuits", page 56).
9 Empty the second patient water circuit via the function [Empty tubes] .
NOTE
You can cancel the emptying by touching the [Emptying] symbol during the
emptying.
The HCU 40 cancels the emptying if a time limit of 2 minutes expires or the
maximum water level of the tank is achieved.
