Startup Procedure (Super Chlorination)

Shocking (Super Chlorination) is recommended before pool startup. Start out with clean pool water
from the beginning. IntelliChlor will build up a sufficient level of chlorine for sanitation in several hours.
However, if pool water has a high demand from the start-up IntelliChlor will not be able to produce enough
chlorine to reach break-point chlorination. So, it is best to super chlorinate from an outside source at the time
of pool startup. Then, wait until the chlorine level has returned to 1 to 3 PPM before turning on IntelliChlor.

Apply power

• 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 scroll all three LEDs for two minutes, indicating that it
has not checked the salt level yet. After two minutes, the salt will be checked and its level will be
displayed with a solid LED. If the salinity is below 2400 ppm, the salt display will light the red ADD
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 (page 6).
• After 24 hours, use a reliable test kit to test the pool water for free active chlorine. The ideal range to
maintain is 1-3 PPM. If the chlorine content of the pool water is too low, increase chlorine
production by pressing the MORE button. If the chlorine content of the water is too high,
decrease chlorine production by pressing the LESS button.
• Due to a varying chlorine demand of pool water, it may take a few days to determine the correct pool
operating time and chlorine production percentage setting for your pool. Continue adjusting as
necessary, allowing 24 hours between adjustments until the chlorine content of the pool is stabilized at
1-3 PPM.

Operating in winter

The unit turns off in water temperatures of 52° F and below, and will not produce chlorine. This feature
extends the life of the cell. See "Winterizing," page 11.

Recommendations

• After new pool construction has been completed, before installing the IntelliChlor cell, install the
IntelliChlor pass-through cell (P/N 520588) to remove debris from the pipes.
• Read and keep the manual in a safe place.
• Increase Chlorine Production before party time and return to normal afterwards.
• Increase Chlorine Production when temperature goes up.
• Increase Chlorine Production when number of guests goes up.
• Use Stabilizer (Cyanuric Acid) to Stabilize Chlorine in Pool.
• Take Pool water sample to Pool Professional once per month.

General Cautions

• Do not get fertilizer in your pool. Fertilizers contain nitrates, which cause a high chlorine demand on
pool water.
• 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 byproducts can damage the electrolytic cell.
• Do not add any pool water balancing chemicals (including salt) unless IntelliChlor is switched off.
• Do not let Chlorine Stabilizer drop below 50 PPM.
