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
prefiltre of the pump.
START-UP
When the filter has been loaded, the sand must be washed. Proceed as follows:
1.- Place the selector valve in the "LAVADO" (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" (FILTERING)
position.
When this has been done, the filter will be ready to start the filtering cycles for the water in the swim-
ming pool.
IMPORTANT: The pump should be switched off when the position of the selector valve han-
dle is being changed.
MAINTENANCE
Do not use solvents for cleaning the filter, this could damage the filter, especially its finish.
Always replace the joints and pieces that may not be in good condition.
Backwash and rinse when needed, as per the instructions specified in this manual.
Clean the sand every year for a better performance with solid or liquid ASTRAL Filnet product. It's rec-
ommended to change the sand inside the filter aproximately every 3 years.
