IntelliChlor Electronic Chlorine Generator Installation and User’s Guide
IntelliChlor Electronic Chlorine Generator Control Panel and Cell Description
The IntelliChlor Electronic Chlorine Generator (IECG) includes a control panel with buttons and LED
indicators to control the IECG and produce chlorine. The IECG measures the water temperature and salt level
to produce chlorine at the defined output. If the salt level in the pool water is too low (red on salt display), the
cell is turned off until salt is added to the pool. The controller has a self-cleaning cycle which reverses the cell
polarity, reducing calcium buildup. This feature turns the cell on and off at regular intervals to prevent calcium
and scale buildup and further maximizes cell life.
The IECG contains the control electronics and bipolar electrodes that electrically produces chlorine when
energized with DC current. Chlorine is generated as pool water containing salt passes through the cell. The
chlorine production can be varied by either adjusting the sanitizer output level on the control panel and/or by
varying the number of hours the IECG is on each day. The IECG automatically reverses the cell electrode
blades every few hours to help clean the cell. This process does not interrupt the production of Chlorine.
The IECG also contains a mechanical flow sensor to ensure the proper amount of water is passing through the
cell to allow chlorination to occur. The IECG automatically measures the water salinity and temperature and
displays four (4) salinity ranges on the control panel using LED indicators. The IECG includes a 15 ft. UL
approved four conductor 16-gauge cable for connection to the Power Center.
• Flow Sensor: A flow sensor assures that there will always be adequate water flow through the
IECG. If the IECG is not properly plumbed and/or does not receive adequate water flow, no chlorine
will be produced.
• Temperature Sensor: To protect the IECG from operation and potential damage when the
temperature of the pool water falls below 52° F, ±3° F (11° C, ±1.67° C), the temperature sensor
switches the IECG off, and no chlorine is being produced.
• Salt Sensor: Two (2) salt sensor probes in the IECG are activated each time the IECG is switched
on and again during every 12 hours of continuous running. At each of those times, the salt level LED
indicator lights flash in a scrolling sequence for two (2) minutes to indicate that the IECG is in
analysis mode. After two (2) minutes, the LED indicators lights will signal one (1) of four (4) salinity
ranges. For more information, see “Salt Level Status LEDs” on page 7.
IntelliChlor System Components
An IntelliChlor Electronic Chlorine Generator IntelliChlor system consists of one or more of the following:
• PC 100 (P/N 520556): Power Center Kit. Provides power and control communication to and from the
IntelliChlor cell.
• IC 20 Cell (P/N 520554): Designed for pools up to 20,000 U.S. gallons (75,000 liters). The cell will
produce the equivalent of 0.70 pounds of pure chlorine per 24 hours of continuous pool pump run
time. The IC20 cell uses two terminal blades and five bi-polar blades.
• IC 40 Cell (P/N 520555): Designed for pools up to 40,000 U.S. gallons (150,000 liters). The cell will
produce the equivalent of 1.40 pounds of pure chlorine per 24 hours of continuous pool pump run
time. The cell uses three terminal blades and ten bi-polar blades, five on each side of the center
terminal blade.
• IntelliChlor “dummy” bypass cell (P/N 520588): For new pool start-up.
