Following this operation, all of the dirt obstructing the cartridge will have
been poured into the drainage pipe.
RECIRCULATE:
In this position, the selector valve allows the water from the pump to go
directly to the swimming pool without passing through the inside of the
filter.
WASTE:
If the swimming pool needs to be drained, this can be done using the filter
pump. In order to do this, the selector valve should be in the "WASTE" po-
sition. 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 clea-
ner valves are closed.
RINSE:
After the carrying out the "BACKWASH" operation on the filter and pla-
cing 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 rea-
ching the swimming pool there is a "RINSE" position for the selector valve
which is operated as follows: immediately after the "BACKWASH" put the
valve in the "RINSE" position and switch on the pump for 1 minute, after
which the pump is switched off and the valve placed in the "FILTER" posi-
tion. 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:

the inside of the cartridge and the seat of the seal in the cover assembly.

mishes.
