Dialysis fl uid preparation
Pressure regulators:
After pressure regulator PR 1 and the
heat exchangers:
80 kPa (0.8 ±0.1 bar)
After pressure regulator PR 2:
130 ±10 mmHg
Temperature:
Adjustable 33 to 40 °C. Accuracy is
valid only if dialysis fl uid temperature is
greater or equal to ambient temperature.
Alarm limits: Adjustable 33 to 40 °C
Accuracy: +0.5/-1.5 °C (+1,0/-2.5 °C with UFD-kit)
at the dialysis fl uid outlet from the
machine.
Heater capacity: 1000 W (+10% / -5%) at 100 V 1300 W
(+10% / -5%) at 110 V 1750 W (+10% /
-5%) at 230 V
Overheat protection: Reg-temp 80 °C or Cond A-temp 70 °C
in treatment, software Reg-temp 99 °C
in disinfection, software. The heater can
only be on if there is a fl ow through the
heater. The fl ow is detected by a fl ow
switch.
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 fl ow rate).
Accuracy: ±40 mmHg
Dialysis fl uid pressure: -400 to +300 mmHg.
Accuracy: ±10 mmHg or ±5%
Proportioning of concen-
trates:
The proportioning of concentrate is
done through conductivity control. The
concentrates are pumped into the system
with one/two volume trically supervised
pumps. No minimum feeding pressure
is necessary, the fl uid is sucked in.
Maximum feeding pressure, 150 kPa.
Acetate: Na

, 130 to 160 mmol/l, (±3 mmol/l)
Bicarbonate: Na + , 130 to 160 mmol/l, (±6
mmol/l)HCO
3
- , 20 to 40 mmol/l,
(±6 mmol/l)
Measuring range: 13 to 16 mS/cm
Alarm limits: ±5% of the calculated conductivity set
