IntelliChlor®Salt Chlorine Generator COMSYS-8 Overview
The IntelliChlor COMSYS-8 commercial system consists of four IntelliChlor cells and four power centers
(one primary and three secondary).
Each cell can produce up to 2.00 lbs of pure chlorine per 24 hours of operation. These cells can sanitize either
a pool or spa, or combination of both. A commercial system requires an external ORP panel and sensor to
produce chlorine upon demand as needed. The ORP system is sold separately.
Features
• Each cell draws approximately 220 Watts.
• Dry contact wires on primary power center connect to chlorine controller panel (ORP system).
Closing these wires turns the Comsys system on with an output level of 100%. The system is now
producing chlorine. Opening these wires turns the Comsys system off with an output level of 0%, so
the system is not producing chlorine.
• Each cell produces 2.00 pounds of chlorine per 24 hours.
• Comsys-8 (4-cell - 1 primary and 3 secondary) produces eight pounds of chlorine per day.
• The ORP system (not provided) is a separate device that monitors the available chlorine in the water
and, when needed, calls for chlorine to be produced by closing a dry contact output. An ORP system
consists of a panel, usually with an LCD display, that has the ORP sensor in the water.
Preparing the Site
1. Add salt to the water until it measures 3600 ppm. Use an electronic tester to measure salt, such as
the Extech EC400. DO NOT USE SALT TEST STRIPS AS THEY TEND TO BE INACCURATE.
Allow the salt to mix for 24 hours before using the IntelliChlor system.
2. Locate a clear spot on a wall, within 15 feet of the IntelliChlor manifold.
3. Locate a clear spot on the return line where the IntelliChlor manifold will be mounted. Be sure that
the user can readily see the lights and press buttons if needed.
4. Be sure 110VAC or 220VAC is available and on its own circuit breaker, to power the IntelliChlor
power centers. This separate breaker will make it easier to service the IntelliChlor.
5. Be sure 110VAC or 220VAC is provided to the power center bank in a conduit, for maximum safety
and NEC compliance.

Assemble the Manifold
1. Place an o-ring into groove on union coupling.
2. Place each cell on the manifold and tighten coupling nut securely. Be sure the o-ring stays
in place. Note: Cells labeled PRIMARY and SECONDARY can be placed anywhere in
the manifold, they do not need to be in a specific location.
3. Glue the manifold into the system plumbing at desired location. The manifold MUST be
installed vertically. Make sure the cells are readable and the buttons can be pressed if
needed.
CAUTION: Do not install upside down!
4. Verify water flow direction See the FLOW arrow located on the IntelliChlor cell near the
input coupling.

Operation
When the ORP system requests chlorine, it closes the dry-contact output that is connected to the ORP
SENSOR wires, and causes each cell to set its output level to 100%. The CELL light will turn on and
chlorine will be produced. If the ORP system is not requesting chlorine (ORP SENSOR wires open),
all lights in the SANITIZER OUTPUT section will be off, no chlorine is produced.
Chlorine will be produced only when:
• SANITIZER OUTPUT 100% light is on
• CELL is green and not flashing
• FLOW light is green
• Salt is FLASHING GOOD, GOOD, or CHECK SALT
Note: Verify each cell has a green FLOW light, to show that adequate water is flowing through the
cell.
• After power up, all cells will scroll the salt lights LOW, CHECK SALT and GOOD for 2 minutes
while waiting to check salt. If FLOW is red, these lights will scroll indefinitely.
• After 2 minutes of green FLOW, the salt will be read and all cells will now display the same salt
color.
• If the CELL light is flashing, the cell has become dirty and requires acid cleaning. Turn off the
circuit breaker to the power centers, disable water flow through the manifold (either an external
valve or turn off the filter pump), and remove the cell. Check the cell and acid clean if necessary.
Power Up the system
1. Switch theAC circuit breaker to ON to applyAC power to the system.
2. After the system is powered up for one minute, if any SECONDARY cell shows a red light,
the communications to that cell is not connected.
Open the power center covers and verify the two green and yellow wires on each terminal block
are connected and in the same order. Verify these connections from each SECONDARYpower
center to the PRIMARY power center (see page 6).
3. Apply water flow to the cell manifold. When water flow is present, each cell's FLOW light
will go from red (no flow) to green (flow).
4. The GOOD, CHECK SALT and LOW salt lights on each cell will scroll back and forth for
two minutes before checking the salt level. If water flow is not present, this two minutes
will start over when flow is restored. Note: THE SALT LEVEL CAN NOT BE CHECKED
WHEN THE FLOW LIGHT IS RED.
5. After twominutes, the salt levelwill be read anddisplayed on all cells.

Troubleshooting
TheIntelliChlor 100% light does not come on whenthechlorinecontrollercalls for chlorine
1. Verify the ORP controller is opening and closing the dry-contact output.
2. Remove the ORP SENSOR wires connection from the PRIMARY power center and the ORP
controller. Manually tie the ORP SENSOR wires together. This will turn on the cells at 100%. If
the 100% lights do not come on for each cell or only one cell, verify the communication wires are
connected, shown in POWER UP THE SYSTEM, step 3, page 7.
The IntelliChlor 100% light stays on after the chlorine controller says to stop
1. Verify the communication wires are connected, as shown in section 5, POWER UP THE SYSTEM,
step 3.
2. Verify the ORP SENSOR wires are not shorted together in the power center.
3. Verify the ORP controller dry contact output is opening and closing by using an ohmmeter. Manually
set this output open and closed using the controller menu system.
The CHECK SALT light is on
More salt needs to be added to the water.
1. Add salt to the water and bring up to 3600ppm. Allow it to mix for 24 hours.
2. The salt level will be automatically checked every 8 hours by the primary cell and displayed.
The LOW salt light is on
Not enough salt is in the water to produce chlorine, cell is OFF.
1. Add salt to the water and bring up to 3600ppm. Allow it to mix for 24 hours.
2. The salt level will be checked every 8 hours by the cells and displayed.
Not enough chlorine is produced
1. Ensure the ORP sensor probe on the chlorine controller unit is clean and working.
2. Verify the IntelliChlor cells do not have a flashing CELL light. If so, remove the cell and acid clean.
3. Verify no debris is in the cells. Remove if present.
4. Verify the FLOW light is green, for adequate water flow.
5. Verify the salt level lights are displaying either green GOOD or yellow CHECK SALT. If displaying
yellow CHECK SALT, add salt to the water, and allow to mix for 24 hours.
6. Verify the ORP controller sets the cells to 100% SANITIZER OUTPUT or 0%, by manually
controlling this output relay (done in the ORPcontroller, not the IntelliChlor) or by disconnecting the
ORP SENSOR wires from the power center and manually opening and closing the wires.
7. Verify the ORP probe is clean.
8. Verify the filter pump is not being turned off by a timer.
