The heater can only be on if there is a flow through the
heater.
The flow is detected by a flow switch.

Accuracy is valid only if dialysis fluid temperature is greater or equal to ambient temperature.
Flow rate: 300-700 ml/min in steps of 20 ml/min
Accuracy: ±10% or 50 ml/min whichever is largest
Degassing: By use of negative pressure , -610 mmHg. Adjustable
degassing pressure between –300 and –700 mmHg (-650
mmHg with 700 ml/min flow rate).
Dialysis fluid pressure: -400 to +300 mmHg.
Proportioning of
concentrates: The proportioning of concentrate is done through
conductivity control. The concentrates are pumped into the
system with one/two volumetrically supervised pumps. No
minimum feeding pressure is necessary, the fluid is sucked in.
Maximum feeding pressure, 150 kPa.
