3. Cyanuric Acid: Sample the pool water and test for cyanuric acid level using a reliable test method.
When using the IntelliChlor Electronic Chlorine Generator the recommended ideal cyanuric acid level
is 50-80 ppm.
4. Calcium Hardness: Test pool water for calcium hardness level using a reliable test method. If
necessary, adjust according to your pool professional’s recommendations. APSP’s recommended
ideal range for calcium is 200 to 400 ppm for pools.
5. Metals Test: It is recommended that the pool water be sampled and tested periodically for the
presence of metals such as copper, iron, and manganese. These metals can damage the IntelliChlor
Electronic Chlorine Generator and other related pool equipment and should not be present in the pool
water. If those metals are present, contact your pool professional.
6. TDS (Total Dissolved Solids): Test pool water for TDS level using test kit or by having a water
sample tested by a pool professional. If necessary, adjust according to your pool professional’s
recommendations. APSP standard of 3000 minimum to 5700 - 6000 maximum ppm (which includes
the salt) is recommended for salt pools.
IECG Usage Hours Meter
The IECG provides a built-in cell “usage hours” meter that reports how many hours IntelliChlor has been
operating. The IECG is designed to operate for approximately 10,000 hours before replacement is needed or
roughly five (5) years of average use.
To access the system status mode:
1. Press and hold the MORE button for three (3) seconds until the lights scroll across the unit.
2. One (1) of the five (5) Sanitizer Output LED indicators (20%, 40%, 60%, 80% and 100%) will be lit,
indicating the hours of usage. The Output LEDs are as follows:
• 2000 hours (20% LED on)
• 4000 hours (40% LED on)
• 6000 hours (60% LED on)
• 8000 hours (80% LED on)
• 10,000 hours (100% LED on)
Cleaning the IECG Cell Blades
1. Automatic Cleaning: The IECG has an automatic cell blade cleaning feature (cell reversing) that
removes scale deposits from the IECG blades. Note: Automatic cleaning does not interrupt chlorine
production. “Scale” is a white crusty deposit that forms in excessively hard water or from pool water
that is out of balance and in a scaling condition. If the IECG blades show excessive scaling, you need
to perform an acid wash cleaning. Proceed to “Acid Wash Cleaning,” Step 2.
2. Acid Wash Cleaning: If the IECG blades show a tendency to scale, it is recommended that every
two (2) months the IECG be removed and inspected for scale formation and/or debris on the IECG
blades. Some filters allow debris to pass through to the IECG, possibly lodging between the blades in
the IECG. A small amount of scale formation is normal. If by looking through the IECG it is observed
that there is excessive scale formation between the blades or debris is present, the IECG must be
cleaned as follows:
a. Use a high-pressure jet of water from a garden hose. If the blades cannot be reasonably cleaned in
this manner, acid cleaning is necessary.
