EcoSalt BMSC 8 Manuel D'installation Et D'entretien page 8

The System Control varies the amount of time the Cell operates during the
filtration cycle.
The System Control will not vary the electrical current supplied to the Cell.
As an example, if one filtration cycle is set at 5 hours, and the System Control is set to
80%, then the total amount of time the Cell will operate during the 5-hour cycle will be 4
hours. If the System Control is set to 60%, the Cell will operate for 3 hours total over
the 5-hour filtration cycle. At 100% the Cell will be ON for the entire 5 hour cycle.
When the System Control is set to 0, the Cell will be OFF for the duration of the
filtration cycle. When the System Control is set to 100%, the Cell will be ON for the
duration of the filtration cycle.
To turn the Cell OFF, simply turn the System Control to 0. This will be convenient for
backwashing.
POLARITY A & B:
These LEDs are used to check that the Cell current polarity is reversing. Whichever is
on (or brightest) indicates the polarity of operation. The Cell will operate in one polarity
for a number of hours so any change in these LEDs will happen slowly and depend on
how the unit is operated.
LOW SALINITY INDICATION
Your EcoSalt® is fitted with a number of protective systems including the operation
LED whose primary function includes Low Salinity Indicator. As the salt level in the
pool decreases, the wear on the Cell increases. Although salt is not consumed in the
EcoSalt process, 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
LED 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 EcoSalt as 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. Refer Maintenance of Electrolytic cell below.
3. Cold Water - cold pool water reduces the ability of a Cell to carry electrical current.
Addition of salt can help compensate for cold water.
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.
