Note: Fill water can have existing salt level. Test with Conductivity Meter
(iv)
Backwash the filters and add the salt by dumping it
along the
deep end of the pool.
DO NOT load all the salt into one area, as it will take longer to dissolve.
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 backwashed out via the bottom
drains. Brush salt to ensure mixing.
If the TDS (Conductivity) 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! It is possible to lower the salt concentration by partially
draining the pool and refilling with fresh water. (Unless the salt level is above 7,000ppm - contact the factory).
It is possible to lower the salt concentration by partially draining the pool and refilling with fresh water.
Salt is effectively not consumed by the ECO-matic process - the salt is recycled.
Note: Always use an approved Digital Conductivity Meter to measure salt content.
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 local authority regulations for checking calcium buildup in the cell.
Pool Stabilizer (Cyanuric acid / Cyanurates)
(For Outdoor Pools Only- where allowed by local authority regulations)
(i)
Measure the stabilizer level using an appropriate test kit. It should be between 15
and 25ppm.
(ii)
If the pool has never had stabilizer added, then approx. 25ppm of stabilizer should be
added.
Follow
the
directions for adding it or load it directly into the pool pump
inlets.
IMPORTANT: Stabilizer is very slow to dissolve and if it is loaded into the
pump inlets it can sit in the filters for a number of days. If the filters are
backwashed it will be lost. Monitor the stabilizer prior to back washing.
(iii)
If there is some stabilizer present, but it is below 25ppm, add enough to make up the 25ppm.
IMPORTANT: stabilizer is for use in outdoor pools only. It is used to reduce the loss of chlorine due to the effect
of sunlight. It should not be used in indoor pools as it may adversely affect pool chlorine demand.
Other Chemical Levels
The other chemical levels to be aware of are pH, Total Alkalinity and Calcium Hardness.
The manufacturer highly recommends that you test and balance your water to L.S. I. ( Langlier Saturation Index) daily.
Simply follow basic pool guidelines, bearing in mind the following:
Swimming pool
Spa
Free available chlorine
1.0 - 3.0 ppm
3.0 - 5.0 ppm
pH
7.2 - 7.8
7.2 - 7.8
Total alkalinity
100 - 120 ppm
100 - 120 ppm
Calcium hardness
200 - 300 ppm
150 - 200 ppm
salt
4000 ppm
4000 ppm
(i)
Very high Calcium Hardness with Magnesium present in the water may present a
problem to the Self-
Cleaning properties of the system and therefore require
additional cell inspections and cleanings.
