8/MAINTENANCE

In order to keep your Zodiac Ei in the best working condition we recommend that you perform

regular maintenance operations.

8.1 INSPECTING AND CLEANING THE ELECTRODE

In zones where the water is hard (high TH) the Ei electrode may have to be cleaned.

To clean the Ei electrode:

1. Turn off the Ei chlorinator, then the filtering system, close the cut-off valves and remove the

cell cap. Remove the cell wire.

2. Unscrew the holding ring and remove the

electrode from the paddle clamp (pay attention

to the small translucent vertical tube). The ring

is crimped, making it easier to remove by hand

(or using the supplied cinch spanner).

If a scale deposit is present, place the electrode

upside down and pour some cleaning solution

into it.

3. If you do not want to use a commercial cleaning solution you can make your own by carefully

mixing one (1) part of hydrochloric acid with nine (9) parts of water (Warning: always pour

the acid into the water, never the opposite!). A stronger solution will reduce the electrode's

life span.

4. Leave the cleaning solution to dissolve the scale deposit for about fifteen minutes. Dispose

of the solution in an approved local waste collection centre; never pour it into the rainwater drain

or into the sewers.

5. Rinse the electrode in clean water and replace it in the cell body (there is an alignment

failsafe).

6. Replace the holding ring, reconnect the cell cable and put the cap back into place. Turn the

filtering system on, then the Ei chlorinator.

7. Confirm chlorine production and operating settings on the Ei command box. The clock settings

are saved automatically.

IMPORTANT NOTE: If the water is too hard (highly calcareous water TH > 40 °f or

400 ppm), it is possible to alter the length of the polarity inversion cycles on your Ei

chlorinator in order to obtain a better self-cleaning effect on the electrode.

If this is the case contact your reseller.

8.2 BATTERY / MEMORY

The Ei chlorinator is equipped with an internal long lasting rechargeable battery (accumulator).

It allows autonomy of about 500 hours (3 weeks). This battery ensures that all the settings are

stored in memory in between 2 filtering cycles, also in the case of a power outage.
