FILTRATION PROCESS

The selector valve has a handle of 6 positions that selects any of the necessary operations to obtain the maximum
efficiency from the filter.
IMPORTANT: Always switch off the pump, when changing the position of the selector valve.
FILTRATION
With the pump switched off, place the handle of the selector valve in the
FILTERING position.
Switch on the pump.
When starting up for the first time, read the pressure of the pressure gauge. It is
recommended to take note of this pressure, as later it will be used to know
whether the filter is dirty and if "WASHING" is required. "WASHING" should be

done when the pressure gauge indicates an increase of 0.5 kg/cm with respect
to the initial pressure of the filter. it is advisable to observe the pressure gauge
from time to time as this indicates the degree of saturation of the filter
Bear in mind that the valves at the bottom of the pool and the skimmers will be
adjusted according to the amount of floating particles on the surface of the
water. The main drain and skimmer valves will be regulated according to the
quantity of floating material found on the surface of the water. Bear in mind that
with the main drain valve fully open there will be little suction from the skimmers.
If the surface sweep of the skimmers is to be stronger, reduce the flow from the
main drain.
initial pressure, indicating that WASHING is required.
BACKWASH
Each load of sand forms thousands of channels which pick up all the material
contained and caught up in the filtering process, the number of free channels
allowing the water to pass is continually decreasing. This is why the pressure rises

progressively until it an increase of 0.5 kg/cm . At this pressure the filtering sand is
unable to collect any more impurities and must be cleaned as follows:
Turn the selector valve to the "BACKWASH" position and with the main drain and
return valves open, switch on the pump and run it for 2 minutes. When this operation
is completed, the dirt blocking the filter will have been removed.
Attention: Too much time in this operation could cause damage to the filter
collector unit.
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.
