Pool sand filter system FSP-500 including sand

The pool sand filter complete system FSP-500 comes with a base plate, on which the filter tank made of polypropylene is located. The tank is equipped with a 6-way valve with a pressure gauge and a glued connection fitting ø50 mm. The circulation pump, which has a capacity of 9 m³/h and an additional hair filter, is also located on the base plate and is connected to the filter tank via a flexible hose. The filter uses filter sand (recommended grain size 0.6-1.2 mm) to catch impurities from the pool water. The filter tank is filled with filter sand and acts as a dirt collector. When the valve is in the "filter" position, the contaminated pool water is sucked through a hose system and automatically pushed into the control valve with patented filter and from there into the upper part of the filter tank. The water is then pushed through the sand, which removes fine impurities, and discharged into the lower part of the tank. The water is then directed back into the pool through hoses via the control valve. The entire process is continuous, automatic, and ensures complete filtration of the pool water. After a certain operating time (4-8 weeks), dirt accumulates in the filter tank, leading to a deterioration in the water flow through the sand and a reduction in the flow through the filter unit (indicated by an increase in pressure on the pressure gauge). This means that it is time to clean the filter. To do this, simply move the operating lever of the 6-way valve to the "rinse" position. This automatically reverses the water flow so that the water flows from the bottom through the filter sand to the top and flushes the accumulated impurities into the drainage line. Once the filter has been flushed, switch the valve lever to "pre-filter" and turn on the pump for half to one minute. Then move the valve lever back to the "filter" position to resume normal filter operation.
