Sequestering agents will help keep minerals in
solution and under some conditions can prevent
scaling from happening. Consult your pool
professional about the use of a sequestering agent.

Optimum Pool Water Conditions

In accordance with Association of Pool and Spa
Professionals (APSP) standards, we recommend the
following water balance conditions be maintained on
an on-going basis to protect the pool finish and the
equipment and to ensure the pleasing appearance of
the water. The Zodiac AquaPure Ei Series APURE35C
is warranted to operate properly only if the following
conditions are met:
Free Available Chlorine
pH
Total Alkalinity
Calcium Hardness
Salt
Cyanuric Acid
(for outdoor pools only)

Chlorine Testing

If additional chlorine is required due to heavy bather
loads, use sodium dichlor, calcium hypochlorite, liquid
chlorine or trichlor to maintain an appropriate chlorine/
bromine residual in the water. Use a home test kit or
ask your pool professional to test your water. Check
the expiry date of the test kit as test results may be
inaccurate if used after that date. It is recommended
that chlorine test samples be taken from two (2) places,
described below. Compare the two (2) samples. A higher
level should be found at the pool return line. The higher
level at the pool return line indicates the salt water
chlorinator system is producing chlorine.
1. At the pool return line.
2. 46 cm (18 in.) below the surface and well away
from the pool return line.
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.

Installation and Operation Manual
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.
