7.0 ADDING SALT TO POOL OR SPA
7.1
Adding Salt
7.1.1
DO NOT add pool/spa chemicals directly to the skimmers (if applicable). This may
damage the cell. Maintaining high salt levels above the recommended range can
contribute to corrosion of pool/spa equipment. If the chlorinator has already been
installed, it must be turned off before adding salt. The recommended salt
concentration for the E-Series is
3500 ppm
.
7.1.2
It is best to empty the required salt around the perimeter of the pool and run the
filtration simultaneously while the E-Series chlorinator is off to circulate the water
and dissolve the salt. Do not throw salt bags into the pool or spa as chemicals and
inks on the bag can interfere with the water balance.
7.1.3
Salt may take 24
– 48 hours to dissolve in the summer and longer in the winter.
Finer granules of salt will dissolve faster than compressed pellets.
7.2
Type of Salt to Use
7.2.1
The purer the salt the better the life and performance of the electrolytic cell. Use a
salt that is at least 99.8% pure NaCl. The preferred salt is an evaporated,
granulated, food quality, non-iodized salt.
7.2.2
Avoid using salt with anti-caking agents (sodium ferrocyanide, also known as YPS
or yellow prussiate of soda) that could cause some discoloration of fittings and
surface finishes in pool.
7.2.3
Water conditioning salt pellets are compressed forms of evaporated salt and may
be used but will take longer to dissolve.
7.2.4
Do not use calcium chloride as a source of salt (use sodium chloride only).
7.2.5
Do not use Rock salt. Insoluble impurities mixed with the rock salt can shorten the
life of the unit.
7.3
Salt Level
7.3.1
The Compu Pool E-Series chlorinator can work with a broad salinity range, from a
minimum of 3000 ppm (parts per million), up to 6000 ppm. However, the ideal level
for operation is 3500 ppm. To achieve this level of salinity, add 3.5kg. of salt for
every 1000 litres of water. If you are unsure of the number of litres in the pool,
double-check with the equations below.
