4.4.2 Changing the Setpoint Ice Block Size
WARNING!
The water quality can influence the ice sensors which, in turn, can influence ice
formation.
The displayed, detected ice block size may therefore deviate from the actual ice
size.
n
Open the tank cover and check the actual ice size visually.
n
Adjust the setpoint ice block size if the actual ice size differs from the setpoint
size.
NOTE
Reduce the ice block size if continuous patient warming is maintained for longer
than six hours
If ice formation and patient warming operate in parallel for several hours, it may
result in severe ice formation in the patient circuit tank.
n
In this case, you should decrease the setpoint ice block size for the patient
circuit or deactivate the setpoint ice block size completely. This prevents the
tank from freezing up and consequent loss of circulation.
