CAUTION
Never use dry acid to adjust pH in arid geographic
areas with excessive evaporation and minimal
dilution of pool water with fresh water. A buildup of
by-products can damage the electrolytic cell.
• The pH condition resulting from the operation of
the saltwater chlorination system is close to neutral.
However, other factors usually cause the pH of
the pool water to rise. Therefore, the pH in a pool
that uses this type of chlorination system tends to
stabilize at approximately 7.8. If the pool pH rises
above 7.8 have a qualified service representative
test to see if other factors such as high calcium
hardness or total alkalinity are the cause and then
balance accordingly.
• Total Dissolved Solids (TDS) adding salt to pool
water will raise the TDS level. While this does not
adversely affect the pool water chemistry or clarity,
the pool water professional testing for TDS must be
made aware salt has been added for the sanitizing
system. The individual performing the TDS test
will then subtract the salinity level to arrive at the
correct TDS level.
New pool water in a recently filled or newly
•
refinished pool may contain undesirable matter.
This undesirable matter could interfere with the
saltwater chlorinator's ability to sanitize properly.
Make sure the water is tested by a qualified service
representative and properly balanced before turning
on the chlorinator system. New plaster pools have
a constant acid demand for six (6) months. Regular
testing and correcting of the pH will reduce the need
for manual cleaning of the cell.
Sequestering Agents may be used in some areas
•
where the total hardness of your source water
may be unusually high. High total hardness
can contribute to scale formation in the pool.
Sequestering agents will help keep minerals in
solution and under some conditions can prevent
this from happening. Consult a qualified service
representative about the use of a sequestering agent.

Optimum Pool Water Conditions

As part of daily maintenance, we recommend the
following water balance conditions be maintained on an
on-going basis to protect the pool finish and equipment
and ensure the pleasing appearance of the water. The
Nature Fusion Soft is warranted to operate properly
2
only if these conditions are met.

4.5.1
Add salt to the pool if the salt is too low (see Table
1). 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. Follow the pool
surface manufacturer's guidelines for your particular
pool. For vinyl and fiberglass pools, salt can be added at
start up.
4.5.2
• 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 ideal salt is an evaporated,
granulated, food quality, non-iodized salt. Consult
your local pool professional.
• 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).
