– AquaA 3600H/4000: 10 L + 0.4 x length of the ring main(s)
Example calculation for an
AquaA AquaA 2700H/3000 with 250 m ring main:
– 8 L + (0.4 x 250) = 8 L + 100 L = 108 L
The rinse volume to be programmed should be at least 108 liters.
Example calculation for an
AquaA2 – If an AquaA2 is connected, the calculated rinse volumes of the
AquaA must be increased by the factor 2.
Example calculation for an
AquaHT – For a connected AquaHT , an additional 2.5 L must be added to the
rinse volume.
AquaA device output:
– AquaA 900H/1000: device output 6 L/min
– AquaA 1800H/2000: device output 13 L/min
– AquaA 2700H/3000: device output 20 L/min
– AquaA 3600H/4000: device output 26 L/min

Calculation example for an AquaA 2700H + AquaHT and a ring main length of 300 m:
Based on the above calculation example, 134 L of dialysis water must
be replaced.
Rinse time = (134 L) / (20 L/min ) = 6.7 minutes

Rounded up, this equals a minimum rinse time of 10 minutes .

As an alternative, consult the table. When doing so, round up the
volume to be diverted to the next-highest value.
Note
Rinsing can be performed with or without discarding the dialysis water.
If
“0 liters” is entered, dialysis water will not be discarded, and will
instead only be circulated.
For this option, the minimum rinse volume must however be previously
adapted to the calculated total volume. The minimum time is calculated
on the basis of the system capacity and the total volume to be replaced.
