C. Electrolytic cell: due to electrolytic cell is major component to produce chlorine,
regularly checking and clean electrolytic cell is very necessary.
D. Metal. Pool water should not contain metal such as Copper, Iron, manganese, etc.
NOTE
Salt chlorine electrolytic cell has self-cleaning function, sel clean by reverse the
polarity every other four hours, which prevents calcium from accumulating and keeps the
electrolytic cell in optimal performance. If water hardness is high or the water chemistry is
out of balance, the cell will need to be cleaned regularly.
Pool water salt concentration adjustment and maintenance
1- Pool water volume calculation
Knowing the volume of the pool is the first step to add salt to the pool (m3).
Rectangular pool: Length (m) x Width (m) x Average depth (m) = water volume of the
pool (m?).
Circular pool: Diameter (m) x Diameter (m) x Average depth (m) x 0.785 = water
volume of the pool (m?).
Elliptic pool: Length (m) x Width (m) x Average depth (m) x 0.893 = water volume of
the pool (m?).
Edge pool: Area of the pool (m3) x 0.85 = water volume of the pool (m3).
2- The type of salt that can be used.
The higher the purity of the salt, the better the LASWIM salt chlorine generator performs
and lengthen its service life. The Sodium Chloride (NaCl) in the salt should be higher
than 99.6%. Dehydration treatment food grade non-iodized salt would be the best choice.
NOTE
A. Do not use rock salt, since it may contain impurities or other compound that may
shorten the lifetime of the salt chlorine generator.
B. Do not use CaCl2 as a source of salt, use NaCl only.
C. Water treatment salt pallets can be used, but the time it takes to dissolve into the water
may be longer.
D. Avoid to use of anti-caking agent salt (NaCN, YPS, it is toxic and corro-sive), this type
salt may result in colour change of pool surface and equipment.
3- Adding the appropriate amount of salt
Most swimming pools contains a certain amount of salt, the concentration of the salt in
the water may vary depending on the water source and the sterilization chemicals in the
water. A handheld NaCl measuring instrument or salinity pen can be used to test for the
current salt concentration in the water. Please use the chart on the back to see how much
salt needs to be added.
A. Suggested salt concentration is around 2700-4500 ppm (between 0.27% to 0.45%),
this would be the optimal water quality.
