8. New Pool Water in a recently fi lled or newly refi nished pool may contain undesirable matter. This
undesirable matter could interfere with the AquaPure's ability to chlorinate properly. Make sure the
water is tested by a pool professional and properly balanced before turning on the AquaPure.

4.5 Optimum Pool Water Conditions

In accordance with Association of Pool & Spa Professionals (APSP) standards, we recommend the
following water balance conditions be maintained on an on-going basis to protect the pool fi nish and
equipment and ensure the pleasing appearance of the water. The AquaPure is warranted to operate properly
only if these conditions are met.
Free Chlorine
Combined Chlorine (Chloramines) None (Super Chlorinate to remove all Chloramines).
pH
Chlorine Stabilizer (Cyanuric Acid) 50 - 75 PPM
Total Alkalinity
Calcium Hardness
Metals (Copper, Iron, Manganese) None
Nitrates

4.6 Chlorine Testing

It is recommended that chlorine test samples be taken from two places. Compare the samples. A higher
level should be found at the pool return line. The higher level at the pool return line indicates the AquaPure
is producing chlorine.
1. At the pool return line.
2. 18 inches (457 mm) below the surface and well away from the pool return line.

4.7 Salt (NaCl sodium chloride)

4.7.1

When to Add Salt?

For a new pool or newly resurfaced pool it is recommended to wait 14 days (surface should be completely
cured) before adding salt. Follow the pool surface Manufacturer's guidelines for your particular pool. For
vinyl and fi berglass pools, salt can be added at start up.
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 preferred 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 fi ttings and surface fi nishes 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).
1.0 - 3.0 PPM. Above 3.0 PPM may cause corrosion of
pool metals.
7.2 - 7.8 (Use Muriatic Acid to lower pH and Soda Ash
to raise pH).
80 - 120 PPM
150 - 400 PPM
None
