0.8 kg/cm² - 11.4 PSI:

Normal pressure at the

beginning of a filtering

cycle.

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 reaches 1.3 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.
