OPERATION
Servicing and Cleaning the cell
Turn off power to the SPS before removing the CELL.
Once removed, look inside the cell and inspect for scale formation (light colored crusty or flaky deposits)
on the plates and for any debris that has passed through the filter and gotten caught on the plates.
If no deposits are visible, reinstall. If deposits are seen, use a high-pressure garden hose and try to flush
the scale off. If this is not successful, use a plastic or wood tool to scrape deposits off of the plates.
DO
NOT USE A METAL SCRAPER AS THIS WILL SCRATCH THE FINISH AND DAMAGE THE PLATES.
Note that a buildup on the cell indicates that there is an unusually high calcium level in the pool (old pool
water is usually the cause). If this is not corrected, you will need to clean the cell more frequently. The
simplest way to avoid this is to bring the pool chemistry to recommended levels, as specified.
Mild Acid Washing:
Use only in severe cases where flushing and scraping will not remove the majority of deposits. To acid wash:
Turn off power to SPS
Remove cell from piping
In a clean plastic container, carefully mix a 4:1 solution of water to muriatic acid (one gallon of water to one
quart of muriatic acid).
ALWAYS POUR ACID INTO WATER-NEVER POUR WATER INTO ACID. BE SURE TO
WEAR PROTECTIVE GLASSES, CLOTHING AND CHEMICAL RESISTANT GLOVES
The level of the solution in the container should just reach the top of the cell so that the wire harness
compartment is NOT submerged. It may be helpful to coil the wiring before immersing the cell.
The cell should soak for FIVE minutes, then rinse with a high-pressure garden hose.
If any deposits are still visible, repeat soaking and rinsing.
Replace cell and inspect again periodically.
Winterizing
The SPS electrolytic cell and flow detection switch will be damaged by freezing water, similar to other pool
components that require proper winterization. In areas of the country that experience severe or extended
periods of freezing temperatures, be sure to drain all water from the pump, filter, and supply and return lines
before any freezing conditions occur. The electronic control is capable of withstanding any winter weather
and should not be removed.
Spring Start-up
DO NOT
turn SPS on, until the pool water chemistry has been balanced to proper levels.
