System Maintenance Servicing And Cleaning The Chlorinator Cell; Winterizing; Spring Startup - Hayward Pro Logic® Operation Manual

System Maintenance
To maintain maximum performance, it is recommended that you open and visually inspect the cell every 3 months
or after cleaning your filter. The Pro Logic will remind you to do this by displaying the message "Inspect/Clean
Cell" after approximately 500 hours of operation.
The Pro Logic electrolytic cell has a self cleaning feature incorporated into the electronic control's logic. In most
cases this self cleaning action will keep the cell working at optimum efficiency. In areas where water is hard (high
mineral content) or in pools where the water chemistry has been allowed to get "out of balance", the cell may
require periodic cleaning.
Servicing and Cleaning the Turbo Cell
Turn off power to the Pro Logic before removing the electrolytic 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 which has
passed through the filter and 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 (do not
use metal as this will scratch the coating off the plates) and scrape deposits off of 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 may to have to periodically clean the cell. The simplest way to avoid this is to bring the pool
chemistry to the 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 Pro Logic. Remove cell from piping. In a clean plastic container, mix
a 2:1 solution of water to muriatic acid (one gallon of water to two quarts of muriatic acid). ALWAYS ADD ACID
TO WATER - NEVER ADD WATER TO ACID. Be sure to wear rubber gloves and appropriate eye protection.
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 a few
minutes and 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 Pro Logic electrolytic cell and flow detection switch will be damaged by freezing water just as your pool
plumbing would. In areas of the country which 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.
If you are in an area that only experiences occasional freezing conditions, your Pro Logic system may be set up to
circulate the pool water whenever the air sensor drops to the selected freeze temperature threshold. Make sure
the air sensor is recording the correct temperature and is NOT located in the direct sunlight to ensure proper freeze
protection operation.
Spring Start-up
When first starting the pool in the spring time, it is highly recommended that you temporarily set the pool and spa
chlorinator settings (Settings Menu/Pool Sanitizer & Spa Sanitizer) to 0% (off) and then manually shock the pool
with any chlorine based shock product and balance the pool water chemistry per the levels indicated in the Chlo-
rinator Operation section. Make sure to check the salt and stabilizer levels and bring them up to the recommended
levels. Your local Authorized Hayward Dealer or pool store can recommend the best chemical treatment for your
pool. After the water is clear and balanced, then go back and adjust the pool and spa chlorinator settings to the
appropriate levels. Test the pool chlorine level weekly and adjust the chlorinator settings up or down accordingly.
It is usually a good idea to also inspect the cell and clean if necessary at the start of the season. See instructions
above.
