What could be more inviting than a pool of crystal clear water? At Four Seasons of Funour staff is trained to help you seek out the best filter to fit your needs. The key is to having an oversized filter package. Ultra sand filter and pump provides a good balance of clean water in an energy efficient way. Sand filters are the oldest and most popular method of filtration. Sand filters--particularly high-rate sand filters, were introduced more than 25 years ago. These filters come in many sizes and shapes, but they share one thing in common. When in the filtration mode, water always flows from top to bottom. Aside from this fact, sand filters also share another aspect: They all have some sort of lateral or under drain designed with slots or holes to hold back sand while allowing the clean, filtered water to pass through. Outward appearance of filters and internal assemblies may vary, but basically all sand filters operate in the same way.
Sand is added to the filter through a top valve or domed opening in the tank. Vertical standpipes must be covered by a protective cap. A coffee can will also wok nicely to prevent sand from getting into the internal piping. The sand should be poured gently into the filter, being sure not to damage the laterals or under drain. A good practice is to add enough water to cover the laterals or under drain, because this will cushion the falling sand. Once the proper amount of sand has been added to the filter, it functions as the permanent dirt-removing medium. Water from the pool, containing suspended dirt particles, is pumped through the piping system and is directed automatically by a filter control valve to the top of the filter tank. As the water is pumped down through the filter sand, dirt particles are trapped by the sand bed and filtered out. The cleansed pool water is returned from the bottom of the filter tank. After a period of time, the accumulated dirt in the filter causes a resistance to flow, and the flow diminishes. This simply means that it is time to clean (backwash) the filter.
Be certain to read all the directions on filter assembly, operation and maintenance. They are written for you. They will save you time and money in the long run.
Here are some pointers on your sand filter.
1. H2O Silica sand is what we recommend. It is the right size and type of particle to ensure proper filtration. Filter sand is course, shaped edge sand. This increases the ability of the sand to catch debris.
2. Use the right amount of filter sand. (See instructions.) Be sure when adding sand to the tank, DO NOT pour the sand directly on the filter element located on the bottom of the tank. This could cause a crack in the plastic and result in sand being washed back into your pool. Slowly pour sand over the bottom element until it completely covered. Then you can pour sand in more rapidly.
3. After all hoses are properly attached, prime the pump (i.e. Put water in the hair and lint trap, providing your unit comes with one, to eliminate air).
4. Backwash the filter for 2-3 minutes after adding new sand. Backwash is done by changing the position on the filter value which reverses the flow of water allowing the water to come out the waste port on the filter.
5. Run filter at least 8-12 hours daily or longer if necessary.
6. Backwash the filter periodically through the season according to the owner’s manual. If your filter comes with a pressure gauge, as the filter becomes dirty the pressure will rise inside the tank. When the pressure is about 5 to 10 lb. above starting pressure it is a good sign that the filter should be in the Backwashed mode. The return water flow will decrease also when the filter is dirty. Backwashing the filter is a method of reversing the filter flow and stir up debris in the sand bed. While Backwashing the water will come out of the waste port. It is recommended that you hook up a hose to the backwash port of your filter to prevent dirty water spraying around your pool area.
7. Drain the tank and discard the filter sand in the fall. Be sure to put the tank motor in the basement or garage during the winter.
8. Put new filter sand in every season. It is inexpensive and will ensure proper filtration. Continuing to use the same sand from season to season will result in the filter sand becoming smoother (similar to play sand) and decrease the efficiency of the filter media.
Diatomaceous Earth Filters (DE)
This style of filter uses a white powder called diatomite as a filter media. You must be certain to add the required amount, via the skimmer, with the filter running. The DE powder is lost when you backwash or clean the filter, so be sure to add new media when this is done. DE filters remove much smaller particles of dirt from you pool each time the water is cycled through the filter. As result it will keep you water sharper (cleaner) but may need to be regenerated or backwashed more frequently than other styles of filters. Particles of dirt that elude conventional filters can’t hide from Perflex. Its deep cleaning power removes microscopic dust and pollen as small as one micron (one hundred times smaller than a grain of salt) leaving nothing but clean, pure, sparkling water for you and your family. Diatomaceous Earth Filters removes much smaller particles compared to Sand or Cartridge filters.
Be sure to:
1. Always use a high-grade DE powder.
2. Never operate your filter without the proper amount of DE. Too much DE powder could create shorter cycles and higher filter pressure.
3. Use the proper amount. Note: a level 1-lb coffee can is only 10 ounces of DE. We have available in the stores an optional plastic scoop which make measuring DE powder easier
4. Mix the DE powder with water before pouring into the skimmer.
5. Follow bumping and regenerative instructions as outlined in the owner’s manual to increase cycle time.
6. Remember: Algae in a pool quickly clogs a DE filter. To prevent algae in your 7. pool keep your free chlorine level at proper levels and use Super Results Shock Treatment regularly. It is normal for a DE filter’s gauge to increase rapidly if algae is present in your pool water. The filter is rapidly removing those algae particles from the water. When the pressure increases, the water flow decreases.
7. Put filter system (fully backwashed and drained) inside basement or garage for winter season. Do not leave outside.
8. Follow Manufacturer’s instructions when servicing your unit.
Cartridge Element Filtration.
The crystal clear blue water in your swimming pool dances brightly in the morning sun. The Hayward ASL (All Season Long) premium full flow element filter system will ensure warm memories and fun filled days around your aboveground pool. The Hayward ASL filter system not only keeps your pool water at its crystal clear best, it also reduces pool maintenance. ASL features a star shaped cartridge element made of high quality reinforced polyester filtration material. Its deep-pleated “V” design provides a full 360 degrees cleaning area, and easily traps dirt and debris during the filtration process - simply and thoroughly. Hayward’s ASL Cartridge element is also extra large so filter cleaning cycles are extended-up to an entire season without any maintenance of the filter.
Make sure to read the owner guide provided with the filter for proper instructions. The following are highlights as a reference:
1. Make sure that your cartridge element is clean-pressure wash cartridge inside and out. Allow to dry and brush pleated surface areas. To remove algae, suntan oil and body oils, soak for one hour in a solution of Filter Flush (available at any FIM Store).
2. Put element evenly on the collector hub in the bottom of the filter body. Place Easy-Lok lid evenly on filter body and turn clockwise until the notch on the locking ring engages securely to safety latch directly over the drain.
3. Ensure that all lines are connected using hose clamps on secure hoses to the filter. Installation of optional valves makes it easier to work on the filter without getting wet. Prime the motor by putting water inside the hair lint pot basket. Make sure that the pool water level is high enough to fill the skimmer basket on thru wall skimmer mounted on the pool wall.
4. When filter pressure rises inside the tank as indicated on the pressure gauge it means that the cartridge is getting dirty. In the event that you have algae inside your pool or an unusual amount of debris this may result in you needing to clean the element during the season. Refer to the owner manual for additional instructions.
5. The filter should be drained and removed from its operating location and stored indoors. Clean the element at the end of the pool season using your garden hose with a high-pressure nozzle. When the cartridge gets to dirty and will not come clean, replacement cartridge elements are available from a FIM Store.
