Pool filter selector key operation in the automatic pool purifier selector valve

  • Automatic pool purifier selector valve filtration:It comes into operation when it receives the order from a timer installed in the pool control panel or any externally programmed order.
  • Automatic pool purifier selector valve washing: The valve goes into washing mode automatically by installing a pressure switch.

Pool selector key position

These processes also They are used to start up the treatment plant.

Selector valve positions for 6-way pools

First of all, in the pool filter there is a stopcock, called a selector valve, with bypass function that It has up to 6 channels with different functions:

1- Pool purifier shut-off valve position: Filter function

Pool filtration selector key diagram

Pool filter selector key characteristics

  • The filtration position is the one that must always be selected on the valve, that is, Allows normal circulation and filtration of pool water.
  • This position makes the entire filtering circuit in the pool, collecting the water through the skimmers and suction nozzles and passing it through the filter. Once the water is filtered, it is returned to the pool through the delivery nozzles.
  • We must also calculate very well the need for water filtration, which will depend on: the time of year, use of the pool, volume of the pool...
  • On the other hand, we can control the on and off of the filtration with a timer.
  • And, the filtering function is also used when we want to manually vacuum the pool.

2- Pool purifier key position: Pool filter washing, backwashing or backwashing function.

Pool wash selector key diagram

Pool wash selector key characteristics

  • Firstly, the washing position is used to wash the sand in the filter. It is done countercurrently and the dirty water is discarded into the drain. Apart from maintaining the sand, it leaves it loose and ready for use.
  • We reverse the circulation of the filter water to be able to clean it, thus we eliminate impurities and residues from the sand.
  • In any case, this process is executed until we see clean water coming out (normally it will be about 3 minutes).
  • After this step you should always rinse the sand to avoid sending dirty water into the pool.
  • During bathing time, this function must be performed at least 2 times. per week (the more we use the pool, the more need there will be).
  • When we see that the pressure gauge indicates a high pressure, we will perform this function.

3- Pool purifier key position: Rinse function

Pool rinse selector key diagram

Pool rinse selector key characteristics

  • The rinse position is always used after washing the pool filter.
  • Approximately should be done for about 30 seconds after a sand wash to completely remove residual dirt.
  • The water is sent to the drain as it may contain dirt from the filter and be brown in color due to sand.
  • After rinsing, the filtration process can begin normally.

4- Pool filter key position: Empty, drain or drain function in the pool filter.

Pool emptying selector key diagram

  • When the valve is in this position and the pump starts, it sucks water from the pool's sump and suction nozzles, taking it directly through the installation's drain pipe.
  • With this option you can empty the pool completely or only partially, thus renewing the water.

5- Pool purifier key position: Selector valve recirculation function.

Recirculation pool selector key diagram

  • On the other hand, eThis is one of the pool purifier key positions for daily use.
  • In this position, the water does not pass through the filter but rather passes directly from the skimmers and suction nozzles to the valve and is returned to the pool without filtering.

6- Pool purifier key position: Closed or winter function in the pool purifier

Closed pool selector key diagram
