Hayward Perflex EC50C Series Owner's Manual page 6

While Perflex filters are basically resistant to the difficulties often encountered as a result of chemical build-up in swimming pools, it is important to
keep in mind that the mineral content in a pool increases every day as a result of the chemicals and the normal water evaporation process. If the
concentration of minerals is allowed to get too high, the minerals will form deposits on the Flex-Tubes inside the filter, and will eventually result in
shortened filter cycles. To guard against this, a yearly chemical cleaning (soaking) of the Flex-Tube assembly is suggested. Use commercially
available 20% muriatic acid added to water in 1 to 1 ratio; or use other commercial filter element cleaner mixed according to the package
instructions. Use a plastic container.
CAUTION: Chemical Hazard –Chemicals can cause personal or property damage, to avoid use personal protective
gear when handling.
After cleaning, thoroughly flush all affected parts with cold water. Always wear gloves and eye protection when handling cleaning agents.
WINTERIZING
In areas where sub-freezing temperatures can be expected, the filter should be drained and removed from its operating location and stored indoors.
Prior to removal, cycle the filter as described under CLEANING.
