the tubes and heat exchanger. Depending on the length of the tubes, it
may be necessary to top up water (⇨ "Filling/Topping Up Water", page 41
).
6 When the setpoint temperature is reached, a green check mark is displayed
next to the symbols "T
out
" and "T
Set
". Once the medically required temperature
is reached, you can attach the patient to the connected heat exchanger.
NOTE
Canceling temperature regulation in an emergency
If strong cooling is required immediately for a patient, you can cancel the
temperature process of regulating once the medically required setpoint
temperature is reached.
4.3.4 Emptying Water Circuits
WARNING!
Do not empty the tubes until the perfusion has ended.
This function can be used to empty the patient and cardioplegia water circuit
independently of each other after the application. To this end, the touchscreen
displays the symbols for emptying in the "Functions" screen.
Emptying cannot be started when the symbol is inactive. This can be due to the
following reasons:
n Normal circulation is running (Pump in operation).
n De-airing of the tubes in progress.
NOTE
This function only empties the selected water circuit. If you want to empty the
entire system, including the tank, ice block, etc., instead, use the
[Empty system]
function (Emptying the Tank).
1 Touch the [Functions] symbol.
2 Stop the circulation (⇨ "Starting/Stopping Circulation", page 46).
