10. Dialysis mode
Dialysis mode supplies the connected dialysis machines with permeate. (Among other things, the dialysis
machine dilutes haemodialysis concentrate to provide ready-to-use dialysate.)
Impulse back washing (IRS)
During dialysis mode, impulse back washing of the 1st and 2nd stages is carried out according to the
operating times entered
part 1, chapter 14.2, “Parameters for dialysis mode”.
These modes of operation are not indicated on the display and do not affect permeate supply.
Temperature discharge
During temperature discharge, the concentrate is routed via Y9 into the drain system in order to lower the
water temperature in the system. The operator can use menu item 2 to activate or deactivate this mode
of operation (see
part 1, chapter 14.2). If temperature discharging is not activated and the fixed limit
temperature of 35°C has been reached, the system rinses for 3 minutes to drain. During this time the
system has to coole down, otherwise it stopps with a fault message.
NOTICE
Disinfection is not permitted during dialysis.
Dialysis mode
Dialysis mode begins when the operating mode switch is switched to
1 = System ON.
It is also possible to activate dialysis mode by switching the operating
mode switch to 2. In this case, dialysis mode can be activated using the
on/off function on the remote control and display key “Dial”.
The green function lamp “Dialysis” is lit.
Software option Standby only appears when dialysis mode is
activated in switch position 2.
During dialysis mode the rejection rate (RJ) is shown in percent.
It is calculated with the following equation:

Fault message
If a fault is determined in this mode of operation, a fault message
appears. The system may be switched off, depending on the type
of fault.
