GAUGE/INSPECTION PORT ADAPTER The gauge/inspection port adapter provides an easy way to look into the filter at the "top" area of the tube nest assembly. It gives a quick inspection capability to check tube nest condition (algae, calcium or D.E. build-up, etc.) without requiring removal of the filter head. It also allows you to wash off trapped debris and excess D.E. from between the Flex-Tubes and from under the tube sheet by spraying with a garden hose, or use Hayward's Jet-Action Cleaning Wand (EC2024) which attaches to a garden hose. To remove adapter-shut off pump and valves and drain water in filter to below port. Unscrew adapter, with gauge, counterclockwise. To reinstall-thread adapter, with O-ring in place, securely into filter housing. PREVENTIVE MAINTENANCE 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 added 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 and take extreme caution when handling cleaning agents as they can be harmful to the eyes, skin and clothing. After cleaning, thoroughly flush all affected parts with cold water. MODEL NO.
