to 8.0 or above, the chlorine required could be as much as three times the normal
amount. To lower the pH add HYDROCHLORIC ACID. To raise the pH levels add
SODIUM BICARBONATE OR SODA ASH.
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.
To lower add HYDROCHLORIC ACID (a little at a time). To raise add SODIUM
BICARBONATE.
3. SALT LEVELS:
The salt level MUST NEVER BE LESS THAN 4000 ppm (4.0 g/l). The ideal operating
salt level is 4500ppm (4,5 g/l). Operating the Unit with too little salt in the pool will
cause damage to your Cell. For DES units salinity must not exceed 7000ppm.
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 EcoSalt®, and
insufficient salt will damage your Cell.
Low salt levels will destroy the coating on the cell's Anode materials and will void
all Warranty.
The EcoSalt has a built in warning system 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.
NOTE: Swimming pools contain water with a low level of salinity, free chlorine and other
compounds. Any materials in contact with the pool water should be suitable for this
environment. DAVEY EUROPE can not be held responsible for damages that occur to
the materials of other products that come into contact with the water of the pool.
4. RUNNING TIMES & CHLORINE PRODUCTION:
These instructions cover EcoSalt in residential use only.
If you run your chlorinator for 24 hours a day, or for long periods, the Cell life will be
reduced dramatically. It is important that the correct model EcoSalt has been installed on
your pool. Many models are available to cope with small courtyard pools up to
commercial applications. (Consult your local EcoSalt Dealer for more information).
The EcoSalt must be run daily to generate sufficient chlorine to sanitise the pool. During
Summer this is usually minimum eight hours per day, preferably in two periods -
between 6.00 and 8.00am and between 5.00 and 11.00pm. Night time is preferable
because chlorine dissipates rapidly in direct sunlight. If these running times are
