Note 3
: for water drawn from a well it is advisable to carry out routine maintenance once a month, repeating the
operation 2 or 3 times in a row if required, after letting suspended matter settle for a few seconds.
WARNING:
During the washing stage, filtered water is still supplied to the utility.
It is advisable to stop the supply of water to the utilities by closing the valves or the bypass cock (if installed)
downstream of the filter, to reach maximum pressure and obtain the best level of cleaning for the cartridge.
EXTRAORDINARY MAINTENANCE
With time, the cartridge cleaning operations performed through routine maintenance can become an issue due to
possible deposits on the cartridge net.
In this case, perform an extraordinary cleaning procedure on the cartridge as follows:
- stop the flow of water upstream of the filter;
- discharge the filter pressure by opening a valve of the hydraulic system downstream of the filter or the drain
cock;
- open the filter by unscrewing the bowl from the head by using the special opening key (supplied as standard);
- take out the cartridge (use protective gloves to avoid any scratches due to the worn out mesh);
- wash the cartridge under a jet of cold water and, if necessary, use a soft brush to remove most of the impurities.
If the cartridge is damaged, replace it with a new one;
- check that the sealing O-rings are adequately lubricated (replace the O-rings if necessary);
- insert the clean cartridge into its housing in the head;
- tighten the bowl to the head;
- start up the filter again by following the “START-UP PROCEDURE”
WARNING:
the cartridge and the bowl have an average service life: we recommend replacing the cartridge at least
every 3 years. The filter bowl must be replaced with a new one at least every 5 years. Cartridges and bowls that
cannot be used any more must be disposed of in compliance with applicable provisions.
Accurate routing/extraordinary maintenance, and regular programmed controls, guarantee preservation over time
and equipment efficiency.
WARNING:
all routine and extraordinary maintenance operations must be carried out with by hydraulically
disconnecting the appliance. Any operation on the equipment must only be carried out after reading the safety
requirements listed in this manual.
ATTENTION:
the purchaser is authorised to intervene on the equipment only to clean the filtering element. With
regard to operations not described or extraordinary ones, they can only be performed by a specialised technical
assistance centre.
NOTE:
particular conditions of use (type of water, operating pressure, etc.) can result in maintenance being required
more frequently and at closer intervals.
