Adding Salt to Your Pool
Your ECO-matic requires a minimum water salinity of 4000 ppm (parts per million ). An excess of salt
is OK (maximum 5,000 ppm),
but TOO LITTLE SALT WILL CAUSE DAMAGE TO, AND SHORTEN
THE LIFE OF YOUR ‘CELL’ – and void warranties on the ‘Cell’.
At startup of the ECO-Matic ther e must be at least 4,000ppm of sa lt (sodium chloride) in the pool
water. The salt level s hould not exceed 5,000ppm. This is simple to achieve if the following steps are
taken:
(i)
Know, with reasonable accuracy, the pool/spa volume.
(ii)
Measure the pool water TDS (Total Dissolved Solids) prior to adding salt.
Note: the Conductivity Meter should be calibrated for sodium chloride. NOTE: Do not use Rock
Salt or salt which con tains YPS (Yellow Prussiate of Soda) or I odine. Salt should be Fine or
Medium Grade Solar Salt at 99.4% PURE NaCl
(iii)
Calculate the required start - up salt dos e and add it to the pool. Adding 10 kg of salt p er
10,000 litres will rais e the salt concentration by 1,000 ppm (e.g.
In a pool with no salt, a
100,000 litre pool will need 450 kg of salt to reach 4,500 ppm). If the pool is already operating
as a salt pool, simply add enough salt to bring the level to 4,500 ppm
(iv)
Backwash the filters and add the salt by dumping it
along the
deep end of the pool.
Pour the salt directly from each bag into the pool water. DO NOT load all the salt into one area,
but rather move along the pool while pouring to distribute the salt evenly.
During the time the salt is dissolving, do not backwash the filters. Heavier salted water will
tend to flow into the deep end of the pool and could be backwas hed out via the bottom drains .
Brush salt to ensure mixing.
If the TDS is higher than expected then the pool volume may have been over estimated. This is not a
cause for concern as more salt is far better than not enough! (Unless the salt level is above 7,000ppm
- contact your supplier). It is possible to lower the salt concentra tion by partially draining the pool and
refilling with fresh water.
Salt is effectively not consumed by the ECO-matic process - the salt is recycled
If you under-estimate the amount of sa lt required, your ECO-matic will indicate ‘Low Salt’. Simply add
more salt (first being sure that original s
alt is properly dissolved) unt il the ECO-matic indicates
sufficient salt – Refer to your ECO-matic Installation and Operation Manual.
IMPORTANT NOTE: Newly plastered pools should run on traditional chlorine to “cure” the
plaster for at least 2 to 4 weeks before adding the salt. Consult with the Pool Company for
exact timing to ensure you do not void your warranty. Be sure to check for calcium buildup in
the cell every 2 weeks. See page 23 for directions
.
