PREPARATION OF THE SAND

The minipools have an empty lter and so it has to be
lled.
HOW TO FILL THE SAND FILTER
To ll the lter 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 lling is complete, reposition the lter in its
compartment and check that the connections are
correct and that there are no leaks.

WHAT IS THE SAND FILTER?
The sand lter is an effective minipool lter connected to
the recirculation pump's feed line. It consists of a large
container that is two-thirds lled with quartz sand. It retains
the dirt and the suspended particles present in the water.
WHAT IS BACKWASHING?
Cleaning the sand lter 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 lter so that the dirt
can ow into the drain.
In Treesse minipools
the backwashing is
automatic, running
automatically every
48 hours of minipool
use, but can be forced
manually following the
procedure indicated on
the side.
