4. MAINTENANCE
The lifespan of the electrolysis cells is very closely linked to compliance with the settings and instructions
indicated in this manual.
The replacement of cells at the end of their life with so-called 'compatible' cells may lead to a decrease in
production and reduce the life of the equipment. Therefore, it is strongly recommended that you only use
so-called original cells.
Any deterioration due to use of so-called compatible cells cancels the contractual warranty.
4.1. Maintenance tips (monthly)
Water softener
Check the water hardness (TH) at the softener outlet using a suitable test kit (not supplied): the TH must be below
12°f.
Electrodes
When the equipment is stopped, there must not be any whiteish deposits on the electrodes. Check the condition of
the terminals, pins and power cables.
Brine tank
Stir the tank. Check there is salt in the brine tank. Top up with salt if necessary.
4.2. Overwintering the apparatus
1) Turn the equipment off.
2) Connect an 8 mm hose (not supplied) to the electrode drain-off valve.
3) Slightly unscrew the salt-temperature sensor and drain the cell by opening the drain-off valve.
4) Retighten the salt sensor and close the drain-off valve.
5) Restart the electronic unit and perform a manual water injection (see chapter 3.7.20) in the cell for 5
minutes.
6) Turn the equipment off.
7) Repeat operations 3 and 4.
8) Disconnect the 2 electrical connections from the cell, the salt-temperature sensor and the chlorine
evacuation.
9) Loosen the screws on the clamps holding the cell.
10) Remove the cell from its housing by disconnecting the inlet tubing from the quick connector (lower part)
11) Loosen the cell screws.
12) Check the condition of the electrode, seals and power supply cable. Replace these elements if worn or
damaged. If the terminals or pins are damaged or overheated, replace the entire power cable and/or the
electrode.
If the electrode or the bases have limescale on them:
a. Find the cause of the scale and remedy this:
i. Check the salt level in the water softener.
ii. Adjust the supply inversion time according to paragraph 3.7.16.
iii. Check the water hardness at the softener outlet using a suitable hardness test kit (not
supplied).
