4.7 Salt (NaCl sodium chloride)
4.7.1 When to Add Salt?
For a new concrete pool or newly resurfaced pool it is recommended to wait 30 days (surface should be
completely cured) before adding salt. Follow the pool surface manufacturer’s guidelines for your particular
pool. For vinyl and fiberglass pools, salt can be added at start up. After start up add salt as necessary to
maintain proper levels.
4.7.2 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 discoloration 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 (insoluble impurities mixed with the rock salt can shorten the life of the unit).
4.7.3 How Much Salt to Use?
Use Table 2 to determine how much salt will be needed. Most pools contain some salt depending on the
water source and chemicals used for sanitizing. If the salt water chlorinator has not been wired and turned
on yet, a salt test strip or a hand held metre calibrated for NaCl (salt) can be used to determine the existing
salt concentration of the water. If the unit is wired (connected), use it to determine the salinity. Water
temperature can affect the salinity readout, always test salinity at the equipment locations.
Set Chlorine Production to 00%. Operating the unit above 00% production without salt will damage the
electrolytic cell. The
Salinity
button
C
on the sanitizer user interface keypad can be used to determine
salinity in the case of a new pool installation, or a complete water change so long as the Chlorine Production
is set to 00%. See
Section 5.4.2, step 2
.
• 3.0 to 3.5 gpl of salt is recommended for optimum water conditions.
• Low salt concentration below 2.0 gpl will cause premature cell failure.
• High salt concentration above 4.0 gpl may damage the power center.
• High salt concentration above 6.0 gpl may cause corrosion damage to pool fixtures.
NOTE
Should too much salt be inadvertently added to the pool see
Section 7, Troubleshooting
.
NOTE
To convert gpl (grams per liter) of a salt solution to PPM (Parts Per Million) of a salt solution multiply by 1000,
i.e., 3.0 gpl salt X 1000 = 3000 PPM salt.
4.7.4 How to Add Salt to the Pool?
1. Turn on pump to circulate pool water.
2.
IMPORTANT - Turn the chlorine production off by pressing the arrow button
A
and setting
CHLORINE PRODUCTION Rate to 00%
.
3. Determine amount of salt from the following charts.
4. Broadcast or spread the salt into the outer perimeter of the pool, or into the shallow end of the pool for
quick and even distribution.
5.
To avoid clogging the filter or damaging power center and pump, do not add salt through either the
skimmer, main drain, or surge tank
