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”.

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‐

– Never mix NaOCI with HCI as this produces
toxic gas.
– Pay attention to the material safety data
sheets.
– Wear effective personal protective equipment.
2.2 Recommendation for the pre-maintenance weeks
In the weeks leading up to maintenance, preferably fill only as
much salt into the brine storage tank as you will need during the
final weeks before maintenance.

‘Service’ menu.
3. Carry out a visual inspection of the unit including checking for
any leaks.
4. Carry out a visual check of the discharge line for diluted
hydrogen and the outlet into the outdoor air.
5. Allow the system to produce for a minimum of 5 minutes.
Then raise the level switch in the product storage tank and
note the following:
1 - The time elapsed since the last start. A minimum of 5
minutes.
2 - Does the system stop as soon as the operator opens
the door of the control cabinet?
3 - Take a sample of the softened water – the hardness
should be < 0.05°dH.
4 - Cell voltage
5 - Cell current
6 - Cell temperature at the inlet
7 - Cell temperature at the outlet
8 - Flow at the input
9 - Flow at the output
10 - Which salt is used? Does it comply with the specifica‐
tion?
6. Is the liquid level of the brine storage tank normal?
1 - The liquid level should be below the overflow point.
2 - Does the valve close after filling?
3 - Is the liquid level high enough (> 20 cm)?
2.6 How often is acid cleaning needed?
The cells need to be cleaned with acid annually.

3 Annual and 3-yearly maintenance steps when using MP1 and
MP3
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’ :

ðThe cell is rinsed with water for 10 minutes, no chlorine is
produced and no brine is metered. The brine pump works
as the brine pump is still in manual “100 %” operating
mode.

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.
