IntelliChlor Electronic Chlorine Generator Installation and User’s Guide
Try initially setting the pool pump timer to twelve (12) hours. It will take a few days to achieve the correct
amount of pool pump operating time. When IntelliChlor is wired with a pool pump timer results will vary
greatly from one pool installation to the next, so this should be discussed with your pool
professional. The key points are:
• Operate the pool pump at least the minimum time needed for good filtration and adequate chlorine
production by the IECG, according to your pool professional’s recommendations.
• While pool pump timers can reduce energy consumption, the pool pump must be running for the
IntelliChlor Electronic Chlorine Generator to provide chlorine and must remain running long enough to
maintain proper chlorine levels (i.e., 2.0 - 4.0 ppm of free available chlorine).
Note: Exception - For Cold Weather Operation: The unit turns off in water temperatures of 52° F, ±3° F
(11° C, ±1.67° C) and below, and will not produce chlorine. This feature extends the life of the cell.
Start-up Procedure (Super Chlorination)
Super Chlorination is recommended before pool start-up. Start out with clean, properly chlorinated, pool
water from the beginning. The IECG will build up a sufficient level of chlorine for sanitation in several hours.
However, if the pool water has a high demand from the start-up the IECG will not be able to produce enough
chlorine to reach break-point chlorination. So, it is best to super chlorinate using an outside source at the time
of pool start-up. Then, wait until the chlorine level has returned to 2.0 to 4.0 ppm before switching on the
IECG.
Sanitizer Output Settings and Adjustments
• Switch on the pool pump switch or pool pump timer. The IntelliChlor control panel green PWR power
LED light should be on. The salt display will blink all three (3) LEDs (bottom to top) for two (2)
minutes, indicating that it has not checked the salt level yet. After two (2) minutes, the salt will be
checked and one (1) of the four (4) salt level LEDs will be displayed. If the salinity is below 2500
ppm, the salt display will light the red LOW SALT indicator, and the CELL light will go blank,
indicating there is not enough salt in the pool for chlorine to be produced.
• Set the Sanitizer Output to 60% by pressing the MORE or LESS button (see page 8).
• After 24 hours, use a reliable test method to test the pool water for free available chlorine. The ideal
range to maintain is 2.0-4.0 ppm. If the free chlorine level of the pool water is too low,
increase chlorine production by pressing the MORE button. If the free chlorine level of the
pool water is too high, decrease chlorine production by pressing the LESS button.
• Due to a varying free chlorine demand of pool water, it may take a few days to determine the number
of daily pool operating hours and “Sanitizer Output” percentage setting (see page 8) for your pool.
Continue adjusting as necessary, allowing 24 hours between adjustments until the free chlorine level
of the pool water is stabilized at 2.0 - 4.0 ppm, per APSP recommendations.
Operating in Winter
The IntelliChlor Electronic Chlorine Generator switches off and will not produce chlorine in water
temperatures of 52° F, ±3° F (11° C, ±1.67° C) and below. This feature extends the life of the IECG. See
“Winterizing,” on page 23.
