The swimming pool has to be refilled with water until half of the skimmer height. The water must
arrive to the pump by natural flow.
Change the valve position to the BACKWASH position.
Make sure that the joint WASTE a tube that makes the water drain is connected.
Start the filter only after this moment.
Start the pump and make a backwash of about 2-3 minutes.
Right after this stop the pump and change the valve position on RINSE.
Re-start the pump and rinse for about 30 seconds. Stop the pump once again and change the valve
position on FILTER.
Start again the pump. The system is now doing its normal job. It is better to start the filter twice a day
for 4-5 hours. Make the bottom cleaning with the valve position on FILTER. After each bottom
cleaning or when the pressure level shown on the pressure gauge increased 0.2-0.3Bar（3-5PSI） , it
is necessary to run the BACKWASH.
A RINSE of about 30 seconds must follow each BACKWASH.
FILTER CONTROL VALVE FUNCTIONS
FILTER
The water of the swimming pool, after being through the filter's sand, is back to the pool cleaned. Use
this same position for bottom cleaning too.
BACKWASH
The water passes through the sand in the opposite direction and overflow from the drain tube of the
backwash. Start it at least once a week for 2-3 minute and after each bottom cleaning.
RINSE
Through this procedure all the dirty waste are eliminated and the sand is compacted once again. The
dirty water overflows from the drain tube of the backwash.
WINTER
The valve is open so that it will not load on the gasket.
IMPORTANT: ALWAYS SWITCH OFF THE PUMP WHEN CHANGING VALVE'S POSITION.
WINTER STORAGE
At the end of the summer season disassemble the filter and disconnect the tubes. Lead the water
outside the tank and the pump working on the draining tap. Store the filter repaired from the frost. The
sand can stay inside the filter until the next season.
Be really careful when moving the filter because it is very heavy. The damage caused by the frost
is not included in the warranty!
