Installation

IMPORTANT: Always make sure the input power is completely disconnected and all pool equipment is shut off before
attempting any service procedures. All service should be performed by a qualified professional.
1. Turn the power to both the filter pump and the cell's power center off.
2. Remove the old salt cell from the plumbing and unplug it from the cell cord connection it to the power center.
3. Inspect the O-rings on the unions connecting the cell to the plumbing to see if they need replacement. If so,
replace them before installing the new cell.
4. Place the replacement salt cell in line and secure the unions by hand. Do not overtighten with use of tools.
5. Plug the cell cord back into the power supply and turn the filter pump and cell power center both back on
6. Refer to the owner's manual of your salt system for regular operation instructions.

Operation

NOTE: The total working hours for the cell replacements should be less than 8 hours total per day. If you are using a
variable speed pump for 24 hours a day be sure to adjust the chlorine output to 25-30%. If the pump is only running 10
hours per day adjust the chlorine output between 60-80%.
You can use this calculation to determine the appropriate chlorine output for your pool at the suggested 6 hours per
day.
Pump running 24 hours a day x 25% chlorine output = 6-hour cell run time per day at 25%
Pump running 20 hours a day x 30% chlorine output = 6-hour cell run time per day at 30%
Pump running 15 hours a day x 40% chlorine output = 6-hour cell run time per day at 40%
Pump running 12 hours a day x 50% chlorine output = 6-hour cell run time per day at 50%
Pump running 8 hours a day x 75% chlorine output = 6-hour cell run time per day at 75%

Maintenance

There are several routine steps you can take to help extend the life expectancy of your CaliMar® replacement cell and
ensure its usefulness under normal operating conditions.
1. Visually examine the cell each time the "Inspect Cell" LED light comes on. This light will turn on after every 500
hours of operation, and thus if you run your pump six hours per day the light will serve as a reminder roughly
every three months. Make sure to turn the filter pump and cell power center off before doing so.
2. Calcium will build up over time on the cell blades, particularly in periods of high use or where water minerals are
abundant, but cleaning the cell is a simple process that will usually remedy the problem.
