The siphon is obligatory and is necessary in order
to prevent the water from entering the pipes of the
blower and coming into contact with the electrical-
ly live parts, in the event of failure of the non-return
valve, installed in the factor on the minipool side.
If the blower is to be used for the aroma therapy treatment, in-
sert the perfume cartridge in the blower connection pipe as shown.
Once this cartridge is finished, it can be replaced by simply un-
screwing the plug and replacing it with a new one (cartridges are
available from authorised dealers and technical service centres).

SAND FILTER AND SELECTOR VALVE

This is a quartz sand filter, composed of a very sturdy ther-
moplastic container, an internal distribution system in anti-cor-
rosive material and a manual selector valve with 7 positions
(6 operating and 1 standby).

Filling sand

During the installation phase, before filling the system with water,
the filter must be filled with the provided sand.
The suggested amount is indicated on the sticker on the outside
of the filter).
This is done as follows:
Disconnect the pipes from the filtering pump and from the
heater (heat exchanger, if installed) and remove the selector
valve. Then cover the opening of the pipe with the flange (in-
cluded) and pour the quartz sand into the container.
Pour the sand in slowly, distributing it evenly around the pipe.
Make sure that the pipe does not come out of its housing.
When you have finished, remove the flange and keep it for the
next time you need to replace the sand. Clean any residues from
the edge of the container.
Put the selector valve back in place. Re-connect the pipes which
were previously removed and then make the connections to the
ground drainage point (also connect the total drainage valve of
the filter, located at the bottom of it, as shown in the figure).
