METHOD 1
Add 1 part HYDROCHLORIC ACID to 10 parts WATER in a suitable container and immerse the Cell in this
solution. It should not take longer than a few minutes to clean, if it does the Cell should be cleaned more
frequently. If the build – up is not excessive it may be possible to clean the cell plates with a jet of running water.
Return the Cell to its Housing and connect leads to the Head Assembly.
METHOD 2
As an alternative, an approved commercial Cell cleaning solution can be used a number of times effectively.
DAY TO DAY OPERATION:
Four Prime rules must be observed if your unit is to give the best possible service:
1. STABILISER
The importance of pool stabiliser cannot be over – emphasised. It is essential in helping retain chlorine in your
pool. Chlorine is rapidly dissipated by sunlight and the use of stabiliser will reduce this dissipation substantially.
Without stabiliser, it may be necessary to run the Unit for up to three times as long!
Stabiliser should be added at the rate of 500 grams for every 10,000 litres of water. Stabiliser should be
maintained at a level of 30 – 50 ppm. Before adding more stabiliser, have your pool water analysed at your pool
shop to ensure that you do not add too much.
2. pH AND TOTAL ALKALINITY:
A correct pH level must be maintained to prevent problems such as black spot, staining, cloudy water, etc. An
incorrect pH level can damage the pool. Correct pH levels are as follows; Fibreglass – 7.2 to 7.4 Concrete & tiled
– 7.4 to 7.6 If you allow the pH level to rise to 8.0 or above, the chlorine required could be as much as three times
the normal amount.
Total Alkalinity should not be confused with pH, although the two are closely related. Total Alkalinity determines
the speed and ease of pH change. It is measured in ppm – the ideal range is 80 – 150 ppm, or refer to your pool
professional.
You should use a test kit which includes a test for Total Alkalinity. Low Total Alkalinity can cause unstable pH
levels – i.e. An inability to keep the pH constant may cause staining, etching and corrosion of metals. High Total
Alkalinity will cause constantly high pH levels.
3. SALT LEVELS:
Salt is the essential element by which your Unit operates. Not enough salt means not enough chlorine - this simple
rule governs the total operation of your ChloroMatic, and insufficient salt will damage your Cell.
RECOMMENDED SALT LEVEL RANGE:
4500 - 6000ppm
WARNING:
Do not add Hydrogen Peroxide to pool water or through swimming pool hydraulic or sanitiser
system. Use of Hydrogen Peroxide will void warranty on Davey products..
Salt is NOT used up in the process of producing chlorine or by evaporation. Salt is only lost through back -
washing, splash - out, overflow or by leakage from the pool or plumbing. Winter rains can dilute the salt solution in
your pool; therefore salt levels should be checked during this season. In colder water, the ChloroMatic should be
set to
Winter Mode
. (Refer
Winter Mode
page 8).
Low salt levels will destroy the coating on the Anode plates and will void all Warranty.
The ChloroMatic has built in warning indicators to minimise damage resulting from insufficient salt levels, however,
the ultimate responsibility is on the owner to ensure adequate salt levels are maintained all year round.
4. RUNNING TIMES:
These instructions cover ChloroMatics for residential use only.
If you run your chlorinator for 24 hours a day, or for long periods, the Cell life will be greatly reduced. It is important
that the correct model ChloroMatic has been installed on your pool. Many models are available to cope with small
courtyard pools up to commercial applications. (Consult your local ChloroMatic Dealer for more information).
WARNING: Follow safety instructions provided with the Hydrochloric Acid or cleaning solution. When
handling Hydrochloric Acid, the use of eye protection, mask and gloves are highly recommended.
Extreme caution should be taken whenever handling Hydrochloric Acid or Cell Cleaning Solution.
Warning: Some people recommend that you put salt directly in the skimmer box. This is a very
poor practice as it allows very high concentrations of salt to be passed through your filtration and
other pool equipment.
