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”.

2.1 Warning information

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.

WARNING!

You are working with chemicals here:

– Sodium hypochlorite 0.9% (NaOCl)

–Hydrochloric acid 5% (HCI)

– Salt (NaCl)

Therefore:

– 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.

2.3 Maintenance intervals

nannually

ncarry out an additional maintenance every 3 years

2.4 You will need the following for maintenance

2.4.8 Service passwords

Your sales partner will provide you with the service password.

2.5 Before undertaking maintenance work: Check and note the following

1. Check the content of the alarm sequence of events in the

‘Service’

menu. If required: Delete the alarm messages.

2. Note down the value of the “Production hours” counter in the

‘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.

It is possibly sufficient to clean them with acid every 3 years if you

are using good-quality salt or the equipment is run for relatively few

production hours each year. Raised cell voltage is the first effect to

indicate that the cells need to be cleaned.

Maintenance of the Chlorinsitu® IIa 625 ... 2500 g/h

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 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 you need to.

3. In the

‘Maintenance’

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.

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

4. Maintain 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 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 tank 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 the valves etc.

6 - Replace the foot valve in the product tank.

7 - Vent 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.

Fig. 3: Disconnect the brine pipework (1) from the inlet of the cells.

11. Disconnect the brine pipework (1) from the inlet of the cells.

Have a vessel ready to collect any water that escapes.

You can remove the 4x6 mm water hose from the water con‐

trol valve (clip-on attachment).

1 - Replace the O-ring on the 3-part coupling of the cell

inlet.

2 - Replace the brine injection valve.

3 - Carry out maintenance on the brine metering pump as

per the operating instructions for the brine metering

pump.

You can remove the brine metering pump from the

internal product tank to work more easily on the liquid

end.

Replace the diaphragm and the valves etc.

INFORMATION! Once you have completed points 2 and 3,

first calibrate brine metering, as otherwise you will have to

dismantle the brine injection valve again.

12. Reconnect the brine supply line if you wish to carry out acid

cleaning.
