Pool sand filter system FSP-500 incl. sand

The Pool Sand Filter System FSP-500 includes a base plate on which the polypropylene filter vessel is placed. The vessel is equipped with a 6-way valve with a manometer and glued connection fitting ø50 mm. The circulation pump with a capacity of 9 m³/h is also placed on the base plate and includes an additional hair filter. The pump is connected to the filter vessel by a flexible hose. The filter uses filter sand (recommended grain size 0.6 - 1.2mm) to collect impurities from the pool water. The filter vessel is filled with filter sand and acts as a dirt collector. When the valve is in the "filtering" position, the contaminated pool water is sucked through a hose system and automatically pushed into the control valve with patented filter, and then transported into the upper part of the filter vessel. The water is then pushed through the sand, which removes fine impurities, and leads the clean water into the lower part of the vessel. The water is then directed back into the pool via hoses controlled by the control valve. The entire process is continuous, automatic, and ensures complete filtration of the pool water. After a certain period of operation (4-8 weeks), dirt will accumulate in the filter vessel, resulting in reduced water flow through the sand and a decrease in flow through the filter unit (indicated by an increase in pressure on the manometer). This means it is time to clean the filter. To do this, simply move the control lever of the 6-way valve to the "rinse" position. This will automatically reverse the flow of water, allowing it to flow from the bottom of the filter sand to the top, flushing out any impurities into the drainage pipe. Once the filter is rinsed, move the valve lever back to the "pre-filtering" position and turn on the pump for half to one minute. Afterwards, move the valve lever back to the "filtering" position to resume normal filter operation.
