3. Adjust the pump manually on the control panel of the pump,
according to the separate pump manual.
– Set the pump to the analog operation mode.
– Set the correct maximum flow rate. See setpoint 6 in section
.
– Exit the pump menu and activate the pump.
4. Push symbol (4) to select the pump.
5. Check that the actual value (5) matches the brine flow
setpoint. See setpoint 5 in section
– If necessary, adapt the actual value with the respective
buttons in field (5).
6. Switch off the dosing pump by pushing pump symbol (3).
If a second brine dosing pump is installed:
7. Switch on the second dosing pump by pushing the pump
symbol and adjust it as described.
8. Push symbol (4) to select the pump.
9. Check that the actual value (5) corresponds to the adjusted
value.
7.2.4 Checking and adjusting the soft water flow and the
salinity of the electrolyte
1. Open solenoid valve (0.05) by pushing the respective symbol
on the display.
– The solenoid valve symbol turns green to indicate that the
solenoid valve is open.
2. Activate the currently selected brine dosing pump by pushing
the symbol.
3. Check and adjust the soft water flow via adjusting valves
(V1.01, V2.01, V3.01) according to setpoint 4. See section
– The setpoint, higher and lower limits and the actual value
measured via water inlet flow sensor (0.02) can be read
from the display.
4. Place a clean measuring beaker under electrolyte sample
valve (V0.06).
5. Carefully open sample valve (V0.06) and take an electrolyte
sample.
6. Close sample valve (V0.06).
7. Perform the measurement according to the separate manual
of the measuring device.
Setpoints (see section
):
– conductivity: Setpoint 9
– specific gravity: Setpoint 14
8. If necessary, adjust the salinity by changing the actual brine
flow on the Selcoperm display (not on the dosing pump). See
pos. 5, fig.
– Observe that the salinity depends on the temperature.
– After adjusting the brine flow, repeat the measurement and
make sure the value matches the setpoint.
9. If a standby brine dosing pump is installed:
– Select the standby pump on the display via the pump
selection symbol (pos. 4, fig.
– Activate the brine dosing pump by pushing the symbol.
– Repeat the salinity check and adjust, if necessary.
10. Deactivate solenoid valve (0.05) and brine pump (DP0.10) by
pushing the symbols.
7.2.5 Checking and adjusting cell outlet level switches (1.09,
2.09, 3.09)
The level switches are pre-adjusted, but need to be checked
during commissioning.
Fig. 34
Cell outlet level switch
Checking the level switches
1. Make sure, that the system and subsequent piping is filled
with electrolyte so that the level switches detect liquid. If there
is not enough electrolyte in the system:
– Activate solenoid valve (0.05) and brine pump (DP0.10) by
pushing the symbols until a sufficient liquid level is reached.
The NaClO sample valve (V0.09) can be opened during
filling until liquid escapes. This indicates a sufficient filling
level.
– Deactivate solenoid valve (0.05) and brine pump (DP0.10)
by pushing the symbols.
The LEDs (1) on all level switches should light up.
2. Switch all 3-way ball valves (V1.02, V2.02, V3.02) to drain
position.

3. Open drain outlet valve (V0.08) until air is visible in the top
electrolysis cells and close it again.
The LEDs (1) on all level switches must be off.
Adjusting the level switch (with filled piping)
If LED (1) is off:
1. Turn adjusting screw (2) clockwise until LED (1) lights up.
2. Turn adjusting screw (2) clockwise by 0.5 to 1 additional
revolution.
If LED (1) is on:
1. Turn adjusting screw (2) counter-clockwise until LED (1)
switches off.
2. Turn adjusting screw (2) counter-clockwise by 1 additional
revolution.
3. Turn adjusting screw (2) clockwise until LED (1) lights up.
4. Turn adjusting screw (2) clockwise by 0.5 to 1 additional
revolution.
The salinity can be checked either by measuring the
conductivity with the Grundfos conductivity
measuring device or by measuring the specific
gravity with the Grundfos Selcoperm test kit.
