RINSE 

 
After  the  carrying  out  the  ”BACKWASH” 
operation on the filter and placing the installation 
in the “FILTRATION” position,  the  water flowing 
into the swimming pool  will be cloudy  for a few 
seconds, so to prevent it from reaching the 
swimming pool there is a “RINSE” position for the 
selector  valve  which  is  operated  as  follows: 
immediately after the “BACKWASH” put the valve 
in the “RINSE” position and switch on the pump for 1 
minute, after which the pump is switched off and the 
valve placed in the “FILTRTION”

 

position. 

 
This position ensures that the filtered water goes  
directly to the drain. 
 

 

 

 

CLOSED 

 

As its name indicates, this position is for closing off the water from the filter 

to the pump and it is used for opening the collector prefilter of the pump.
