The Sandy 6 device is equipped with a four-position changeover valve, the functions of which are as follows:
- filtration (water is filtered, rotated and vacuuming also takes place in this position)
- backwashing (we can clean the sand in the tank in this position, for which we use the pool water)
- flushing (the final step of the cleaning process, the purpose of which is to settle the sand stirred up during backwashing and to remove dirt in the changeover valve and pipes)
- winter position (to be used during wintering, at which time as many openings as possible are open, so that the sand can dry out before the winter frosts set in, as well as ventilate)
