follows: 

 

1.- Place the selector valve in the " BACKWASH "  position. 

 

2.- Open the valves controlling the swimming pool suction pipes and run the 

pump for 4 minutes. 

 

3.- Stop the pump, place the handle of the selector valve into the "RINSE" 

position and rinse for 1 min. Then, stop the pump and place the handle of 

the selector valve into “FILTRATION” position. 

 

When this has been done, the filter will be ready to start the filtering cycles 

for the water in the swimming pool.

of the selector valve handle is being changed
