Decalcification
Lime which is a natural component of water is deposited on the electrodes in the cell. This shortens the electrodes’ lifespan.
The electrodes are self-cleaning since their polarity is reversed every 4 hours of operation. For this to work satisfactorily, it is
necessary for the pool water’s pH rating, alkalinity and so on to be within the recommended limits and the unit to operate for
at least 8 consecutive hours.
If lime nonetheless builds up, the cell has to be decalcified. Water with high alkalinity (above 120 ppm) and high pH (above 7.6)
runs an increased risk of cell scaling. This appears as a white coating between the electrodes.
Inspection between the cell’s plates
. There should be a clear space between them. If the cell is clogged, it can quickly be
totally destroyed!
• If there is a brown coating (iron or manganese) the cell has to be dismantled and cleaned using a special agent.
Contact Pahlén for support.
• If there is a white/light coating (lime) the cell must be dismantled and cleaned using a decalcification agent, see below.
Manual decalcification:
1. Switch off the current supply to the salt chlorinator.
2. Stop the pump and shut off the valves before and after the salt chlorinator.
3. Undo the pipe couplings.
4. Plug one end of the chlorinator.
5. Read and follow the safety instructions for the cleaning agent.
6. Fill the cell housing with cleaning agent. Let it act until all the coating has disappeared. DO NOT poke anything between
the plates or in the cell.
(The cleaning agent is acidic and can be used for pH adjustment in your pool or can be saved for use the next time.)
7. Rinse with water.
8. Refit the cell.
9. Screw the pipe couplings back into place (only finger-tight).
10. Start up and check there are no leaks anywhere.
11. Check that the salt chlorinator can operate at its full production capacity.
Winter/risk of freezing
If there is a risk of freezing, the system must be drained of water and the power supply switched off. The salt chlorinator must be
undone and entirely drained of all water.
Alarms, warnings and fault codes
An alarm is only issued if the limit has been exceeded. When the values return to normal the alarm is reset and so too is the
warning.
Type
What happens - cause
Action
Alarm: A1
Stops production.
A1
appears in the display, steady readout.
Alarm appears when the chlorinator has high voltage (12V).
This occurs when there is too little salt in the pool water or when
the electrodes are used up.
Check the salt content of the pool
water.
Replace the cell package.
Alarm: FLO
Stops production.
FLO
appears in the display with a steady readout when there is
no flow or insufficient flow through the cell housing.
Check the pump, non-return valve
or shut-off valves, check other stop-
pages in the circulation system.
When flow returns to normal, the
alarm is reset and production con-
tinues.
Alarm: HT
Stops production.
HT
appears in the display, steady readout.
This alarm appears when temperature in the cell exceeds 45ºC.
Warning: FAULT A
Production continues.
FEL
and
A
flash alternately.
This warning appears when current to the electrodes is less than
4A.
When current supply is more than
4A, the warning is reset.
Warning: Add SAL
Production continues.
ADD
and
SAL
flash alternately.
This warning appears when the pool water’s salt content is lower
than 0.40 %.
Add salt to the pool water, wait until
it is dissolved.
To raise it by 0.1 %, add 1 kg/m³
pool water.
