4.6 Salt (NaCl Sodium Chloride)
4.6.1 When to Add Salt
Add salt to the pool if the salt is too low (see Table 1) or if salt indicator light turns on. For a new pool or newly resurfaced
pool it is recommended to wait at least 30 days (surface should be completely cured) before adding salt. Do not run the
chlorinator at this time. Manually chlorinate the pool. Contact your dealer for recommendations. Follow the pool surface
manufacturer’s guidelines for your particular pool. For vinyl and fiberglass pools, salt can be added at start up.
4.6.2 What Type of Salt to Use
• 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 salt is an evaporated, granulated, food quality, non-iodized salt. Consult your salt supplier.
• Avoid using salt with anti-caking agents (sodium ferrocyanide, also known as YPS or yellow prussiate of soda) that
could cause some discolouration of fittings and surface finishes in pool.
• Water conditioning salt pellets are compressed forms of evaporated salt and may be used but will take longer to dissolve.
•
Do not
use calcium chloride as a source of salt. Use sodium chloride only.
•
Do not
use rock salt because insoluble impurities mixed with the rock salt can shorten the life of the unit.
4.6.3 How Much Salt to Use
Use salinity test strips, a TDS/salinity meter, or another reliable method to test the salinity of the pool water. Once the
existing salinity has been established, use Table 1 to determine the amount of salt to add to reach the desired level. Be
conservative when adding salt as it is easier to add more if needed than it is to dilute if there is too much salt.
• 4,000 ppm of salt is recommended for optimum water conditions.
NOTE
In cooler water conditions (less than 18°C [65°F]), it may be necessary to add more than 4,500 ppm of salt to keep
the “Check Salt” alarm from appearing on the power pack.
• Low salt concentration below 3,000 ppm will cause premature cell failure.
• High salt concentration above 6,000 ppm may cause corrosion damage to pool fixtures.
CAUTION
It is important to note that certain materials used in and around swimming pools and spas may not be compatible with
chemicals commonly used to purify pool and spa water (e.g. acids, chlorine, salt, stabilizers, etc.).
Zodiac Pool Systems, Inc. does not warrant or guarantee that the chlorinated water generated by the Zodiac AquaPure Ei
Series APURE35PLGC chlorine generating device will not damage or destroy certain types of plants, decking, coping and
other materials in and around your pool and/or spa. Before selecting materials to be used in and around your pool and/or
spa, please discuss all options with your contractor to assess the compatibility of such materials and chemicals.
Some helpful considerations may include:
• Maintaining high salt and chlorine/bromine levels above recommended range can contribute to corrosion of pool or spa
equipment.”
• Choosing plants that can withstand splash out of pool water containing chlorine and/or salt and other water purification
chemicals.
