Maintenance
In order to keep your Zodiac Ei in the best working condition we recommend that you perform
regular maintenance operations.

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 fi ltering
system on, then the Ei chlorinator.
7. Confi rm 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.
9.2 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 fi ltering cycles, also in the case of a power outage.
9.3 Maintenance / Wintering
If you winter your pool (lowered water level and piping purged) your Ei chlorinator must be stopped.
It is not necessary to remove the Ei electrode.
However a wintering cap is available as an accessory which can be used to seal
off the electrode housing when it is removed (for wintering or maintenance).
Contact your reseller if you wish to acquire it.
9.1 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 fi ltering system, close the cut-off valves and
remove the cell cap. Remove the cell wire.
2. Unscrew the holding ring (1) and remove the electrode from the paddle clamp (2)
(pay attention to the small translucent vertical tube).
The ring is crimped, making it easier to remove by hand. 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.
Always wear adapted protective equipment when handling chemicals (glasses,
gloves, overalls) !
4. Leave the cleaning solution to dissolve the scale deposit for about fi fteen minutes.
Dispose of the solution in an approved local waste collection centre; never pour it
into the rainwater drain or into the sewers.
