IntelliChlor®Electronic Chlorine Generator (SCG) COMSYS-12 Overview
The IntelliChlor COMSYS-12 commercial system consists of six IntelliChlor (SCG) cells and six power centers
(one primary and five 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 ORPsystem 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-12 (6-cell - 1 primary and 5 secondary) produces twelve 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.

SAFETY PRECAUTIONS - PLEASE READ BEFORE PROCEEDING
IMPORTANT SAFETY PRECAUTIONS. PLEASE READ THE FOLLOWING:
Read all the safety precautions in this manual before attempting any electrical wiring. Be
sure to read and follow all safety Instructions on page ii.Wiring should only be performed
by a qualified professional. When using electrical products, basic precautions should
always be followed, including the following:
RISK OF ELECTRIC SHOCK,WHICH CAN RESULT IN SERIOUS INJURY OR DEATH. Before
attempting installation of service, ensure that all power to the circuit supplying power to the
system is disconnected/switched off at the circuit breaker. The Power Center must be
interconnected with pool pump motor power source.This insures the IntelliChlor chlorinator and
pool pump will switch on and off together.
• Grounding (earth bonding) is required.The unit should be installed by a qualified service
person and grounded.
CAUTION - Install the IntelliChlor cell a minimum of two (2) feet from the heater outlet.
• Allow ample access to the IntelliChlor control panel buttons and the IntelliChlor Power Center.
• Pipe couplings: Schedule 80, maximum pressure 150 psi at 70° F.
• Operate unit with a minimum flow rate of 25 gpm per celll. For high flow applications, use a
bypass loop.

Wires
1. Mount a JUNCTION BOX on the left side
of the Power Center Banks.
2. Run a CONDUIT(with 208VAC - 260VAC
wires) from theAC BREAKER to the
junction box. Note: ThisAC power should
be on its own breaker for future servicing.
Note: For 110VAC operations, each
power center will need to be re-
configured. A 110VAC wiring diagram is
provided on the inside of each the power
center covers.
3. Run conduit from the junction box into each
of the power centers located on the left side
(PRIMARYand SECONDARY).A(knock-
out)conduit opening is provided on the
bottom of each of power centers.

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, either horizontal or vertical.
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.
IMPORTANT! MANIFOLD ASSEMBLY AND INTELLICHLOR CELL MUST BE
INSTALLED IN THE VERTICAL POSITION, AS SHOWN BELOW.

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 FLOWlight, 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 the AC circuit breaker to ON to apply AC 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
SECONDARY power 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 two minutes, the salt level will be read and displayed on all cells.
