1 Safety
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
nMaintenance may only be carried out by authorised technical
personnel.
nThese maintenance instructions are only valid in conjunction
with the “Installation and operating instructions for the chlorine
electrolysis system CHLORINSITU® IIa”.

1. Use the
[START/STOP] key in the main menu to stop the
system.
2. Rinsing the suction side:
1 - Remove both foot valves from the brine storage tank.
2 - Insert both suction hoses into a 10-litre bucket filled with
water and rinse the suction hoses.
3 - Replace both foot valves.
4 - Put both foot valves back into the bucket.
5 - Turn the rotary switch of the brine pump from
EXTERNAL to “100 %” operating mode to rinse the brine
out of the system.
6 - Vent the brine pump, if necessary.
3. In the
‘Service’ menu, press the [right arrow key] and select
‘Rinse’ :

4. Service the optional chlorine metering pump:
WARNING!
The chlorine metering pump and the hoses
are filled with NaOCI.
– Take precautionary measures as per the
material safety data sheet.
1 - De-pressurise the chlorine metering hose.
2 - If necessary, empty the product storage tank in advance
and fill with water.
WARNING! Never mix the product with an acid as
this will produce chlorine gas.
3 - Set the chlorine metering pump to manual
‘100 %’ oper‐
ating mode; the pump and hoses will fill up with water.
4 - You can remove the pump from the storage tank to be
able to work more easily on the liquid end.
5 - Carry out maintenance as per the operating instructions
for the metering pump.
Replace the diaphragm and valves etc.
6 - Replace the foot valve in the product storage tank.
7 - Bleed the chlorine metering pump and check that it is
working properly.
8 - Wipe away any NaOCI that has escaped, rinse and
clean the surfaces with water.
5. Move the rotary switch of the brine metering pump to STOP.
ðThe pump and hoses are filled with water instead of with
NaOCI.
6. Switch off the external power supply as soon as cell rinsing
has ended.
The cell(s), pipes, sensors etc. are now filled with water
instead of with brine or NaOCI.
7. Disconnect the water supply and open and close the water
softener test valve to bring the system to atmospheric pres‐
sure.

Open both flow sensor threaded connectors in the outlet.
CAUTION!
– Pay attention to the flow sensor’s meas‐
uring cartridge, as it can fall out.
–A direction arrow is located on the flow
sensor. The direction arrow must be
facing upwards.
– Fundamentally do not use any tools to
tighten the 3-part couplings or hex
screws. Tightening them hand-tight suf‐
fices.
1 - Loosen the pipework between the cells and the flow
sensor (left part of the figure above) and remove this
pipework. The temperature sensor must remain in the
line.
2 - Replace all O-rings in the 3-part couplings.
3 - Remove the 2 hex screws from the sensor, and replace
the 2 flat seals above and below the flow sensor - see
figure below.
CAUTION! Pay attention to the flow sensor’s measuring
cartridge, as it can fall out.

B1195
If you wish to carry out acid cleaning, connect the adapter kit
with hose to the outlet of the last cell – far right cell.
WARNING!
Never allow the adapter hose to enter the
product storage tank, as hydrochloric acid
and hypochlorite could produce toxic chlorine
gas.
– Therefore keep the lid of the product
storage tank closed.
Route the adapter hose into an empty 20-litre canister.
21. 1 - Route the suction hose of the brine metering pump into
the 5 % hydrochloric acid.
2 - Turn the rotary dial on the brine metering pump from
STOP to “100 %”.
3 - After 60 minutes, turn the rotary dial on the brine
metering pump from “100 %” to “STOP”.
4 - Leave the adapter hose in the canister.
ð
CAUTION!
The 20-litre canister now contains hydro‐
chloric acid with a concentration of less
than 5 %.
22. 1 - Route the suction hose into the bucket filled with water.
2 - Start up the brine metering pump, by turning the dial
from STOP to "100 %" for 9 minutes.
As soon as the brine metering pump has started up,
press the ‘Rinse cells’ key on the system.
3 - After 9 minutes stop the brine metering pump by turning
the rotary dial from 100 % to EXTERNAL.
Tab. 2: The additional volume of rinsing water in the canister after 9 minutes is approximately:

23. Dispose of or neutralise the hydrochloric acid needed for
rinsing.
24.
B1196
Always replace the outlet line on the cell(s) and the line to the
internal product storage tank.
25. Check and clean the brine storage tank.
You will need to clean the brine storage tank if there is a lot
of dirt in the brine storage tank or if a hard layer of ≧ 5 cm of
salt impenetrable for water has formed on the base.
26.
B1189
Switch on the water supply again:
1 - Slowly open the water supply valve.
2 - Slowly open the valve for softened water to carefully
release the air.
Air is trapped in the water filter, which then migrates into
the water softener.
27. Start up the brine metering pump again:
1 - Route the suction hose of the brine metering pump into
the brine storage tank.
2 - Route the suction hose of the softener into the brine
storage tank again.
3 - Now replace both foot valves with new foot valves.
4 - If necessary: bleed the brine metering pump.
5 - Turn the rotary dial on the brine metering pump to
EXTERNAL.

28. Prepare for calibration of the brine metering pump:
B1197
1 - Connect the adapter to the inlet line for brine and route
the hose into the measuring cylinder filled with brine to
ensure that the lack of injection valve does not distort
calibration.
2 - Make sure that the adapter is upright and at the highest
position to enable the air to flow out.
3 - Turn the rotary dial on the brine metering pump to “100
%”; if necessary, remove the bleed valve on the pump
and the bleed hose.
4 - Allow the pump to run for at least 2 minutes to allow
brine to enter the line.
5 - Turn the rotary dial on the brine metering pump to
EXTERNAL.
6 - Note the liquid level in the measuring cylinder.

2 - Follow the instructions on the display.
3 - The bring pump is calibrated once the volume measured
has been entered in the display.
4 - Turn the rotary dial on the brine metering pump to
EXTERNAL.
5 - Reconnect the inlet line for the brine to the cell.
6 - If necessary: wipe away any brine that has escaped or
rinse it away with water.
30. Replace the filter mat.
B1110
31. In the
‘Settings’ menu, press the [Fill cell] key, filling the cells
for approximately 5 minutes.
32. Press the
[START/STOP] key and let the unit run for a min‐
imum of 5 minutes.
ðA power supply error can occur (
‘Voltage too high’ or
‘Current strength too low’ ). Simply reset the alarm and
restart the unit.
A third attempted start should be successful.
