Main characteristics of pool sand filters
This type of filter uses sand as a filtering agent inside its tank.to retain the impurities present in the pool’s water.
At GRE, we offer you a range of compact, easy to install and use pool sand filters. They do not require special care and can be fitted to any removable pool.
The sand filter monobloc holds a complete filtration set that includes:
– Filter (with a capacity of 4,000 liters per hour at 180 W power).
– 5-Way selector valve.
– Manometer (pressure gauge).
It is mounted on a plastic bench with all the necessary pipe fittings. Our pool sand filters are also certified under the European standard, guaranteeing compliance with the safety regulations in force.
Pool sand filter operation
This type of pool filter has a selector valve that enables it to perform several functions. They are:
In this position, the water inside the filter flows in the opposite direction of the filter and into the drain. This function removes any impurities from the sand filter. The process will be completed when the water being drained becomes clear (approximately 2 minutes). We recommend you use the backwash function at least once a week.
Upon completing the backwash process above, place the valve in the “Rinse” position for 30 seconds to completely rid the piping of any dirt/impurities. Once that is done, place the valve lever in the “Filter” position.
In this mode, the water is filtered and returned clean through the return valve into the pool. This is the function/position the filter unit will remain in most of the time.
In this position, the water goes directly into the drain without passing through the filter.
This option is ideal:
– If you notice a lot of dirt accumulated at the bottom of the pool.
– To lower the water level when (for any reason) it is above the skimmer.
– To drain the pool completely.
In this mode, the water is shut off from the filter unit. It is recommended for winter or prolonged periods without use of the pool.
