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" 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 filter 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 "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" 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.
START-UP
When the filter has been loaded, the sand must be washed. Proceed as follows:
1.-Open the air bleed cap to blow out the air.
2.- Place the selector valve in the "LAVADO" (BACKWASH) position.
3.- Open the valves controlling the swimming pool suction pipes and run the pump for 4 minutes.
4.- Stop the pump, place the handle of the selector valve into the "RINSE" position and rinse for 1 min. Then, stop the
pump and place the handle of the selector valve into "FILTRATION" (FILTERING) position.
5.- Close the air bleed cap when water starts to come out.
When this has been done, the filter will be ready to start the filtering cycles for the water in the swimming pool.
IMPORTANT: The pump should be switched off when the position of the selector valve handle is being changed.
