Reaction mode
Following recirculation mode, the system automatically switches to
reaction mode.

When the reaction time has elapsed, the display calls for sampling cock
PH2 to be opened and the system to be switched to flushing operation
with key > <.
Flushing mode
Flushing is carried out in two alternating phases:
1. Flushing of the disinfectant with simultaneous emptying of the
supply tank
2. Filling of the supply tank while the system is at a standstill
If conductivity control is activated in disinfection operation (see
menu 5.5), the current conductivity at the end of the flushing process
is compared with the permeate quality before the start of disinfection.
If the current conductivity deviates by more than 25% or 2 µS/cm,
flushing is automatically repeated. If the deviation is < 25% or 2 µS/cm,
the request for the manual test “Check for residual disinfectant done?”
is displayed.
System request for checking for residual disinfectant
15 minutes before the flushing operation is completed, a request is
made for a check on residual disinfectant. After the test for residual
disinfectant has been carried out on all sampling and permeate
tapping stations, the next step is initiated by pressing the >
5s
< key
(for 5 seconds).
Repeating the flushing process
If residual disinfectant is discovered, the flushing process including the
test for residual disinfectant is repeated by pressing the >
yes
< key.
This process must be repeated as often as necessary until the system
and the connected pipeline system are free of disinfectant.
As soon as this is the case, the >
no
< key is pressed to end the
disinfection process.
End of disinfection
After disinfection (DI) and subsequent shutdown rinsing, the system
returns to standby mode.
