Maintenance and care of your cell
Proper maintenance of your
cell and the pool salt level can prolong a cells life to its maximum, however
eventually the process of electrolysis will wear away the cells delicate
coating, at which time it will gradually cease to produce chlorine. Average
cell life is 3-5 years.
Mineral salts and calcium
(scale) are deposited on the negative (cathode) plate as electrolysis takes
place. This build-up will interfere with the flow of current in the cell and
lower chlorine production. If allowed to build up unchecked the resultant
overload can damage the cell and the power supply. Because of this, it
is essential to inspect the cell regularly and clean when necessary.
The rate at which deposits will form on the cathode plate differs with each
pool and can be influenced by the following:
- Calcium hardness or the
water
- Water temperature
- pH control
- Water which has been
chlorinated with calcium hypochlorite for an extended period
- Calcium in the plaster
surfaces of a concrete pool
Check the cell at least
weekly to begin with to see when either scale or a blue/green soapy substance
appears. You can then determine the cleaning cycle necessary for your pool
(more frequently in summer). If using bore water, cleaning needs to be as
frequent as once a week. If the cell clogs frequently with a white crystalline
substance increase the salt level but never to more than 0.7% (7000
ppm). If this is done, the chlorine control should
be adjusted anti-clockwise to prevent the unit from running on overload.
Please note: Self regulating and self cleaning systems are protected from
overloading and indicate when the cell requires cleaning or salt needs to be
added. Self cleaning systems utilize intelligent self-clean technology which
virtually eliminates the need for manual cell cleaning except in areas with
extreme water conditions where the cell will require cleaning periodically.
Cleaning Methods
To clean the cell, turn the
power off and removed the cell from the plumbing. Using a suitable container,
add 1 part Hydrochloric Acid to 5 parts water (or better still use a suitable
cell cleaner solution), and immerse the cell in this solution. If it takes
longer than 3-5 minutes to clean the cell, it should be cleaned more
frequently. Thoroughly rinse the cell after cleaning. If the build-up is not
excessive it may be possible to clean with a jet of running water, but take
care not to remove any of the spacers in the cell. Return the cell to the
plumbing. Remember to store acid all cleaning solutions carefully.
Always take care when using acid or cell cleaner solution.
Maintenance of Pool Salt
Low salt levels will
destroy the coating on the positive (anode) plate, and will void warranty. For
recent models the minimum salt level is 4% (4000 ppm)
and maximum of 7% (7000 ppm). Ideal salt levels
are between 5% - 6% (5000 ppm – 6000
ppm).
Colour
Coding
Sometimes the colour coding on your new cell maybe
different to the old one. Here is
the correct method: Positive – Red goes to brown. Negative –
black goes to blue. The small water sensor wire goes to the existing smaller
water sensor wire. Always make sure connections are tight.
