Reinstalling Cartridge Element 1. Clean any collected debris from the bottom of the filter housing. 2. Reinstall cartridge in filter housing. Be sure O-ring is in place on threads. 3. Clean O-ring. For ease of future disassembly, apply a very light film of a dilute solution of non-granulated liquid-type soap to O-ring and threads. 4. Screw filter housing with O-ring into filter head. Do not overtighten. Tighten drain valve and top air relief valve. 5. Secure to system with union nut. 6. Proceed as in Starting the Filter. and allow an hour for soaking. Hose thoroughly before reinstalling in filter. If calcium or mineral deposits are excessive, the cartridge may be restored to "like new" condition by soaking in muriatic acid. Use commercially available 20% muriatic acid added to water in 1 to 1 ratio. Use a plastic container and take extreme care when handling cleaning agents as they can be harmful to eyes, skin and clothing. After cleaning, flush with water. VACUUMING Vacuuming can be performed directly into the filter whenever needed. Clean cartridge after vacuuming, if required. Cleaning Cartridge The cartridge filter element can be cleaned by pressure washing inside and out with a garden hose. Rotate cartridge, hosing from top down. (The cartridge is easier to clean when dry). After hosing the cartridge, for best results, allow cartridge to dry and carefully brush pleated surface areas to remove fine particles. Algae, suntan oil and body oils can form a coating on the cartridge pleats which may not be thoroughly removed by hosing. To remove such materials, soak the cartridge in a solution of filter element cleaner (various brands available at pool dealer). Follow manufacturer's directions for use WINTERIZING In areas where sub-freezing temperatures can be expected, the filter should be drained and/or removed from its operating location and stored indoors. Remove and clean cartridge. Reinstall cartridge in filter tank. Tighten cover only a few turns when storing. SERVICE & REPAIRS Consult your local and authorized Hayward dealer or service center. No returns may be made directly to the factory without the expressed written authorization of Hayward Pool Products, Inc. ALGAE CONTROL Algae is a form of plant life which can vary in size from a few thousandths of an inch to the size of a small tree. Of the many forms of algae, those most frequently found in swimming pool water are microscopic in size and green in color. Algae readily grows in sunlight and can, under favorable conditions, quickly overgrow a swimming pool turning it completely green in just a few hours. On the other hand, swimming pool water can be kept unfavorable to algae growth simply by maintaining a chlorine level of at least 1.0 ppm in the water at all times. The chlorine level should be checked at least once a day using a suitable test kit. If an algae condition develops and the pool water "blooms" green, superchlorination of the pool will be necessary to clear it. Add unstabilized granular chlorine, or liquid chlorine. Follow chemical manufacturer's recommendation for superchlorination. The algae will quickly become inactive and can then be removed by the filter. Live algae, on the other hand, multiplies so fast, that the filter cannot keep up with its growth rate. When correctly used, commercial algaecides are effective against algae, though algaecides should be used in conjunction with, and not as a substitute for, regular chlorination or superchlorination. Maintaining a chlorine level of at least 1.0 ppm in the pool water at all times is the most effective way to prevent algae growth in swimming pools.
