Cleaning a CircuPool RJ Series Salt Cell
Cleaning a salt cell is part of regular maintenance for a Saltwater pool. As the cell plate gets calcium build-up on it the salt production will drop and sometimes stop completely. I have cleaned just about every salt system out there and the CircuPool is an easy one to clean if you use its cell stand.
CircuPool Cell Cleaning Stand:
Expected Maintenance
After the system has run for a time, your cell will eventually need to be cleaned due to natural mineral scaling. The system will notify you of this by turning on the “Cell Maint.” light. When illuminated, follow the cleaning instructions below under "Cleaning the Electrolytic Cell".The frequency of cleaning depends on your water chemistry and the Saturation Index of the water. For most people, cleaning is only necessary a handful of times per season. The more rapid mineral build-up is a sure sign of a chronically high Saturation Index; imbalanced chemistry can cause scaling to occur quite rapidly. Consult a pool professional for additional help.
Cleaning the Electrolytic Cell
Once substantial deposits have built up on the titanium plates in the Cell, the “Cell Maint.” light will illuminate, and the mineral scaling must be removed. To do so, follow these steps: Important precautions: When cleaning the Cell always wear adequate protection, such as rubber gloves and eye protection. Always add acid to water, do not add water to acid. Always work in a well-ventilated area. Splashing or spilling acid can cause severe personal injury and/or property damage. Before removing the Cell for cleaning or replacement:
1) Turn off all power to all pool equipment, and close supply line valves if
applicable.
2) Unplug the Cell cable connecting the Cell to the Control Module.
3) Disconnect the Cell by unscrewing the Threaded Collars around the
PVC unions where the Cell attaches to the return line plumbing.
4) Remove the entire Cell from between the unions. DO NOT pull or hold
the Cell by its cable.
MAINTENANCE
Cleaning the Electrolytic Cell (Continued)
To clean the Cell of mineral buildup:
1) Attach Cleaning Cap or Cleaning Stand (sold separately, available at www.circupool.com) and orient the Cell vertically. Place on the ground and stabilize to remain upright and prevent spilling.
2) In a separate bucket, mix one part of muriatic acid into four parts of water. Pour this weak acid solution directly into Cell. Ensure that the cleaning solution fills the inside of the Cell.
3) Allow the solution to soak for no more than fifteen minutes.
4) Properly dispose of the acid solution, and use a hose to generously flush any remaining debris out of the Cell.
5) Look inside the cell to check that no debris or scaling remains. Repeat steps 2-4 if necessary.
6) Reinstall Cell into the PVC return line.’
Note: if you don’t currently have a Cleaning Cap, you can completely immerse the cell body in a five-gallon bucket. For instructions, see the guides listed under www.circupool.com/help. Note: If the mineral build-up is severe, more than one cleaning may be necessary to dissolve the remaining solids. Inspect cell plates closely with a bright light after cleaning. If you see any remaining scaling, debris, or physical blockages through Cell, repeat the cleaning process as needed. If “Cell Maint.” comes back on soon after cleaning, verify salinity and system cell version setting, then clean the cell again.
