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.

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.
