LOW SALINITY INDICATOR
Your Chloromaticis fitted with a number of protective systems including the Low Salinity
Indicator (operation LED’s). As the salt level in the pool decreases, the wear on the Cell
increases. Although salt is not consumed in the Chloromaticprocess, it is lost through
splashing, back - washing and on bathers as they leave the pool. The salt level is also reduced by
rain, which causes dilution. Salt is not lost to evaporation. As the salt level in the pool falls
toward the minimum Operation LED2 will turn RED. At this point the salt level should be
increased by adding 25kg of salt per 25,000 litres of pool water. The addition of salt should not
affect the Chloromaticas it is protected against overloads. If no action is taken and the salt level
continues to fall damage to the system may result.
There are other factors that can cause the Unit not to work correctly:
1. Heavy Rain - can cause very dilute pool water to pass over the Cell due to surface skimming.
2. Scaled Cell - a scaled Cell will not draw as much electrical current as a clean Cell when first
started.
3. Cold Water - cold pool water reduces the ability of a Cell to carry electrical current. (Refer
Winter Mode below).
4. Failing Cell - as the Cell ages there will come a time when the electrical current draw will
drop. This can be compensated for with the addition of extra salt. A Cell is considered failed
when it draws less than 80 % of maximum current. To keep a failed Cell in operation Winter
Mode can be used along with extra salt. There will come a time when the Cell will not
respond to either extra salt or Winter Mode. It will then need to be replaced.
Please note that the Low Salinity Indicator is not like T.D.S. meters, which are temperature
compensated Scientific Instruments. The accuracy will be within 500ppm salinity and they
are water temperature dependent, just as the Cell is.
WINTER MODE:
When the Cell draws electrical current from the Power Supply, the amount of current drawn is
dependent upon a number of factors. Two of these factors are Salinity and Water Temperature.
The Low Salinity Indicators on your Chloromaticare designed to operate at swimming season
water temperatures. When the pool begins to cool in the off season the temperature drop causes
the Cell to behave differently - it will draw less electrical current. This can cause the Low
Salinity Indicator to assume that the salinity has fallen even if the salinity has remained
relatively constant.
When the temperature of the pool water drops, the Winter Mode Switch should be placed in the
ON position. The Winter Mode Indicator will then be ON. This has two effects:
1. It alters the setting of the Low Salinity Indicator .
2. It reduces the Cell Output by approximately 15%
The Unit will now respond to a cold pool environment. Winter Mode should not be used in
the swimming season as it reduces the Cell Output, leading to less sanitiser, and it alters the
setting of the Low Salinity Indicator, which could lead to premature Cell failure.
