IntelliChlor Electronic Chlorine Generator Installation and User’s Guide
Chlorine Testing
It is recommended that chlorine test samples be taken from two (2) locations in the pool. Compare the
samples. A higher level should be found at the pool return line. The higher level at the pool return line indicates
the IECG is producing chlorine. Take chlorine samples for testing at:
• The pool return line.
• 18 inches (457 mm) below the surface and well away from the pool return line.
What Type of Salt to Use
The purer the salt, the better the life and performance of the IntelliChlor Electronic Chlorine Generator. Use
salt that is at least 99.8% pure NaCl, sodium chloride. The preferred and recommended salt is an evaporated,
granulated, food quality, non-iodized salt with no additives. Consult your salt supplier.
• Avoid using salt with anti-caking agents (sodium ferrocyanide, also known as YPS or yellow prussiate
of soda). Filling agents can 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. Such pellets could damage pool plaster and other surfaces in and around the
pool.
• Do not use calcium chloride or potassium 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 IECG).
How Much Salt to Use?
Use the Table 1 chart (page 13) to determine how much salt will be needed. Most pools contain some salt,
depending on the water source and chemicals used for sanitizing. Therefore, the pool owner must always test
salt levels before adding salt. A hand held meter calibrated for NaCl (salt) can be used to determine the salt
levels of the pool water. After the IntelliChlor Electronic Chlorine Generator is powered on, the LED salt level
lights will blink from bottom to top for two (2) minutes while it analyzes the pool water, then the LED
indicators will show one (1) of four (4) salt level ranges. This solid light indicates the salt status of the pool.
• 3000 to 3500 ppm of salt is recommended for optimum water conditions.
• Low salt concentration below 2500 ppm will cause the unit to turn off
• High salt concentration above 4200 ppm may cause excessive corrosion or deterioration to pool
equipment and surrounding surfaces in and around the pool.
Note: Salt measurements will vary between measuring devices (salt test strips, electronic testers, and
titration). For more troubleshooting information about high salt levels, see “Troubleshooting,” on
page 33.
CAUTION - Do not operate the IECG with newly poured pool plaster or a newly constructed pool,
regardless of pool lining material. Severe salt damage can occur. FOR ALL NEW POOLS, wait at least
ONE (1) MONTH after construction and filling of pool water before operating the IECG.
