WASTE:
If the swimming pool needs to be drained, this can be done using the fil-
ter pump. In order to do this, the selector valve should be in the "WAS-
TE" position. The motor is run with the main drain valve fully open, for
the pump to have sufficient suction. For the pump to suction, keep the
prefilter and the main drain pipes full of water. Before drainage, make
sure that the skimmer valves and the bottom cleaner valves are closed.
RINSE:
After the carrying out the "BACKWASH" operation on the fil-
ter and placing the installation in the "FILTER" position, the water
flowing into the swimming pool will be cloudy for a few seconds,
so to prevent it from reaching the swimming pool there is a "RIN-
SE" position for the selector valve which is operated as follows: im-
mediately after the "BACKWASH" put the valve in the "RINSE" po-
sition and switch on the pump for 1 minute, after which the pump
is switched off and the valve placed in the "FILTER" position.
This position ensures that the filtered water goes directly to the drain.
CLOSED:
As its name indicates, this position is for closing off the water from the of
the filter pump and it is used for opening the collector prefiltre of the pump.
MAINTENANCE:
Do not use solvents for cleaning the filter, this could damage the filter,
especially its finish.
Always replace the joints and pieces that may not be in good condition.
Backwash and rinse when needed, as per the instructions specified in
this manual.
It's recommended to change the cartridge the filter aproximately every
3 years.
CARTRIDGE ASSEMBLY:
If you replace a cartridge, you should proceed as follows. Thoroughly
clean the inside of the cartridge and the seat of the seal in the cover
assembly. Check that all parts are in a good state of repair, free of
cracks and blemishes.
• Place the cartridge in its correct position. Gently press it downwards.

traces of dirt in the housing.
