Pool sand filter system FSP-500 including sand

The Pool sand filter complete system FSP-500 is equipped with a base plate on which the filter housing made of polypropylene is located, which is equipped with a 6-way valve with a pressure gauge and glued connection fitting ø50 mm. The circulation pump including additional hair filter with a capacity of 9 m³/h is also placed on the base plate, which is connected to the filter housing via a flexible hose. The filter uses filter sand (recommended grain size 0.6 - 1.2mm) to capture impurities from the pool water. The filter housing is filled with filter sand and acts as a dirt collector. When the valve is in the "Filter" position, the contaminated pool water is automatically sucked in through a hose system and pushed into the control valve with patented filter, from where it is transported to the upper part of the filter housing. The water is then pushed through the sand, which removes it from fine impurities, and discharged into the lower part of the housing. Via the control valve, the water is returned to the pool through hoses. The entire process is continuous, automatic and ensures complete filtration of the swimming pool water. After a certain period of operation (4-8 weeks), dirt deposits in the filter housing and lead to a deterioration in water flow through the sand and a decrease in flow through the filter unit (recognizable by an increase in pressure in the pressure gauge). This means it's time to clean the filter. To do this, simply put the operating lever of the 6-way valve in the "Rinse" position. The water flow is automatically reversed, so that the water flows from the bottom up through the filter sand and flushes the settled impurities into the drain line. Once the filter is flushed, set the valve lever to "Pre-filter" and turn on the pump for half to one minute; then the valve lever is brought back to the "Filter" position so that normal filter operation resumes.
