1.- Take off the clamp and the valve with the gasket. 

 

2 - Cover the opening of the inner pipe in order not to drop sand inside it.  

 

3.- Fill the filter with water to half capacity. 

 

4.- Pour the required quantity of sand inside the filter. 

 

5.- Clean the seating of the gasket joint. 

 

6.- Fix the filter valve in place. 

 

FILTRATION PROCESS 

 

The  selector  valve  has  a  handle  of  6  positions  that  selects  any  of  the 

necessary operations to obtain the maximum efficiency from the filter. 

 

IMPORTANT: Always switch off the pump, when changing the position 

of the selector valve.

 

 

FILTRATION 

 

With  the  pump  switched  off,  place  the  handle  of  the 

selector valve in the” FILTRATION” position.  

 
Switch on the pump. 

 

During  this  operation,  it  is  advisable  to  observe  the 
pressure gauge from time to time as this indicates the 

degree  of  saturation  of  the  filter.  When  the  pressure 

reaches 18.5 PSI a “BACKWASH” should be carried out.  
The  main  drain  and  skimmer  valves  will  be  regulated 

according  to  the  quantity  of  floating  material  found  on 

the surface of the water. Bear in mind that with the main 
drain valve fully open there will be little suction from the 

skimmers. If the surface sweep of the skimmers is to be 

stronger, reduce the flow from the main drain.
