Commercial Salt Chlorinator | Installation & Operation Manual
ENGLISH
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.).
As such, Zodiac Pool Systems LLC does not warrant or guarantee
that the chlorinated water generated by the salt water chlorinator 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:
• Choosing plants that can withstand splash out of pool water
containing chlorine and/or salt and other water purification
chemicals.
• All metal components used in and around a pool should be of a
high grade, quality stainless steel.
• Careful selection of masonry products. The porosity and hardness
of natural stones varies greatly. Therefore, we recommend you
consult with your builder or stone contractor on the best choice for
stone materials around your pool or spa.
• Sealing all masonry products. Professionals in the stone industry
specify that even natural stone, especially when used outdoors, be
sealed to prevent weathering, staining, and premature degradation.
Consult with your stone or deck contractor for the proper sealer for
the masonry products you have selected to use around your pool
or spa.
• For the optimal results, sealers should be reapplied on a regular
basis. Reapply the protective sealer on a schedule per the
manufacturer’s instructions.
4.8 Salt (NaCl Sodium Chloride)
4.8.1 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.
4.8.2 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 44% pure NaCl. The salt is an
evaporated, granulated, 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).
4.8.3 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 meter
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.
• 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 6.0 gpl may cause
corrosion damage to pool fixtures.
NOTE:
Should too much salt be inadvertently added to
the pool see the
Troubleshooting
section.
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.
4.8.4 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 the salt concentration using a
portable test meter (test ship, conductivity
meter).
