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 polypropylene filter tank is mounted, which is provided with a 6-way valve with a pressure gauge and glued connection fitting ø50 mm. The circulation pump, including an additional hair filter with a capacity of 9 m³/h, 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 0.6-1.2mm) to collect impurities from the pool water. The filter tank is filled with filter sand and acts as a dirt catcher. When the valve is set to "filter", the contaminated pool water is sucked in via a hose system and automatically pushed into the control valve with a patented filter and from there into the upper part of the filter tank. The water is then pushed through the sand, which removes it from fine impurities, and discharged into the lower part of the tank. The water is then returned to the pool via hoses through 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 water flow through the sand and a decrease in flow through the filter unit (as evidenced by an increase in pressure in the pressure gauge). 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 automatically reverses the water flow so that water flows from the bottom up through the filter sand and flushes out the accumulated impurities into the drain line. Once the filter has been flushed, switch the lever of the valve to "pre-filter" and turn on the pump for half to one minute; then move the valve lever back to "filter" so that normal filter operation resumes.
