3) Connect the union of the mouth for water entry into the pool with the RETURN union of the 4-way
valve.
4) Connect an adequate tube with the WASTE mouth when the backwash function is desired so that
dirty water can be drained out to a chosen site.
All tubes must be fastened with safety clamps.
Fill up the pool – make sure the water level covers about halfway the suction mouth of the wall skimmer.
Now the system can be started up. Follow the instructions below.
5. STARTING UP THE FILTER/PUMP
1) Make sure the plug is disconnected. Set the lever on the BACKWASH position. Switch the pump on
and carry out a backwash for a few minutes to eliminate any sand that could have settled during
filling up. Switch the pump off.
2) Now set the lever on RINSE; switch the pump on and rinse for a minute. Switch the pump off.
3) Set the lever on FILTER. Switch the pump on. The filter is now operating normally and is carrying out
its function at an optimum level.
We recommend you to use the filter at least twice a day for 3-4 hours and to do a backwash for a few
minutes after each cycle.
6. CLEANING THE BOTTOM OF THE POOL
Switch the pump off and insert the skimmer in the special brush holder (vacuum). Make sure all the air
comes out.
Set the lever on FILTER. Switch the pump on and brush the bottom and the walls. Make sure no air
enters as it could defuse the pump or cause damage to it by making it work without water.
When cleaning is finished, stop the pump, turn the lever to BACKWASH, switch the pump on and wash
for one minute to eliminate dirt. Switch the pump off, set the lever on RINSE, switch the pump on for half
a minute for a light rinse. Cleaning operations are now finished.
7. STORING IN WINTER
At the end of the summer season, disconnect the tubes, remove water from the filter by opening the
tap.
Water must also be emptied from the pump and it must be placed in a dry place, where it cannot be
damaged by the cold.
The sand may be left and reused during the next season.
8. SAFETY RULES
The pump must be connected to the electric network by a 30 mA differential switch.
Always disconnect the pump from the electric network before carrying out any kind of operation on the
filter or pump.
