Although the cells provided by Best Pool Supplies is manufactured from high quality materials with longevity in mind, over the period of time the electrolysis will wear out the cell coating which will in the end result the electrodes to stop producing chlorine.
Here are some handy hints that help you to prolong the life span of your chlorinator cell:
- Don’t overwork your salt cell – running the chlorinator at 100% output or longer than 8 hours a day will shorten is life.
- Use Conditioner or Stabilizer to protect your chlorine from breaking up in the UV of the sun which will again prevent overworking your salt cell.
- Keep proper pH balance. PH level below 7.2 will etch the salt cell, and if above 7.6 will reduce the chlorine’s effectiveness. To reduce the PH use pool acid or dry acid and raise the PH using soda ash.
- Maintain proper salt level in the pool. Low salt levels will destroy the coating of the electrodes and high salt levels will overload the chlorinator.
- Inspect the cell regularly and once you notice scale build up on the electrodes clean it with appropriate Salt Cell Cleaner.
Calcium deposit (formation of scale) is one of the main reasons of premature failure of the chlorinator electrode. Scale on the electrodes will reduce the chlorine production, restrict the flow of the water and if not addressed it will put unnecessary strain not only on the cell but also on the powerpack and can cause damage to both. It is important to check the cell and clean the electrodes from scale when it becomes necessary.
How quickly calcium builds up on electrode(s) varies from pool to pool and depends on on various factors:
- Your geographic location – areas with hard water and when bore water is used the scale forms quite quickly.
- The pool finish - calcium from the pool plaster (concrete pools) or grouts (tiled pools) can raise the calcium levels of the pool water.
- Pool chemicals - super chlorinating with calcium hypochlorite affects pool water calcium content.
- Unbalanced PH level of the water plays role in calcium build up on the electrodes.
- Incorrect salt level.
If you your chlorinator is non self cleaning (does not reverse polarity) it is advisable to check the cell once a week (even more often during summer months). If the milky white substance starts to appear on the electrode(s) you know it is time to give the cell a clean.
These days most new chlorinators on the market are self cleaning. These units avoid scale build up on the electrodes by reversing the polarity between the electrodes, repelling mineral deposits, which are washed away by the pool water rushing through the cell housing before they can attach to the oppositely charged electrode. Even if the chlorinator is self cleaning, the cell still needs to be cleaned roughly once every 6 months (more often in hard water areas). Many of these intelligent units advise you when it is time to clean the cell and warn about low salt level in the pool water as well.
To clean the cell:
Switch off the chlorinator and remove the cell from the housing following manufacturer instructions.
- If the scale layer is not very heavy the deposits can be washed away with a garden hose. (NB! Do not brush the electrodes or scrape with sharp objects.)
- If the above does not help, it is needed to soak the cell in suitable cleaning solution like Salt Chlorinator Cleaner or self mixed acid solution. To prepare acid solution mix 1 part of Pool Acid (Hydrochloric Acid) with 5 parts of water in the bucket. Submerge the cell into the solution for 3-5 minutes. If it takes longer than 5 minutes to clean the cell it is an indication that the electrodes should be cleaned more frequently.
- Put the cell back into cell housing.
NB! Always take extra care when handling chemicals and store them out of the reach of children.
Replacing Zodiac Ei Chlorinator Cell
When replacing this electrode you should reset the cell OPERATING HOURS. The system has a built in HOUR meter recording your run time of the electrode.
If you get a message “CHECK CELL” this does not stop your chlorinator from working but rather a bit of information telling you a cell change is due (similar to modern cars that have annoying hour meters built in).
The CHECK CELL message on your Chlorinator is not always a fault, it is simply to remind you to check your equipment from time to time. It comes up when your cell has done 6000 hours or more.
To reset your run hours (recommended when installing this new cell) or to clear the message please follow these steps:
- Press and hold the MINUTE button for about 10 seconds, until you see the CELL HRS & CHLOR HRS displayed.
- Press the HOURS button to reset the CELL HRS. NOTE: The CHLOR HRS cannot be reset.
- Press CLOCK button to get back to the main menu. The message will now be gone.
NOTE: Your chlorinator was still working as normal while this message was on the screen.
