PREPARATION OF THE SAND
FILTER
The minipools have an empty filter and so it has to be
filled.
HOW TO FILL THE SAND FILTER
To fill the filter use the sand supplied and follow the
instructions provided on the following page.
If the sand has to be replaced it must be similar to the
kind supplied (for food use). If necessary contact the
Manufacturer for more details.
When filling is complete, reposition the filter in its
compartment and check that the connections are
correct and that there are no leaks.

More information
WHAT IS THE SAND FILTER?
The sand filter is an effective minipool filter connected to
the recirculation pump's feed line. It consists of a large
container that is two-thirds filled with quartz sand. It retains
the dirt and the suspended particles present in the water.
WHAT IS BACKWASHING?
Cleaning the sand filter is essential because it retains pollut-
ing materials like hair or leaves and sediment if the minipool
is installed outdoors.
The best cleaning is achieved with a backwash, i.e., with a jet
of clean water from the bottom of the filter so that the dirt
can flow into the drain.
