9.2 Cleaning the Built-in Filter

For correct working of the system and achieving the declared performance, clogging of the filter must be prevented.
Check the filter cartridge periodically through the transparent cover and, if necessary, clean it as described below.
1.
disconnect the electric supply and wait for 10 minutes;
2.
if the system is installed with positive suction head, close the On/Off valve at the suction end;
3.
remove the filler cap by unscrewing it manually or use the tool included in the supply;
4.
remove the cartridge without rotating it. the relative filter cup-support is also released;
5.
empty the cup and wash the cartridge under running water;
6.
refit the cartridge back in place taking care to make sure it fits in the cup by means of a bayonet coupling;
7.
close the filler cap so that it comes to a mechanical stop.
If the system is to be reused, and not stored away, restore the pump suction and repeat the filling (Sect.2.2) and priming
(Sect.3.3) operations, preferably before point 7. in case of suction lift installation.

9.2 Emptying the system

If you want to drain the water out of the system, proceed as follows:
1.
disconnect the electric supply and wait for 10 minutes;
2.
if the system is installed on a plant, cut off the suction duct at the point nearest to the system (it is advisable to
have an On/Off valve immediately upline of the system) so that the entire suction system is also not discharged;
3.
if the system is installed on a plant, open the nearest delivery tap to discharge pressure to the plant and drain it
as much as possible;
4.
If the system is installed on a plant, if an On/Off valve is present immediately downline (it is always advisable to
have one), close this to prevent the quantity of water from flowing back to the plant between the system and the
first tap open;
5.
disconnect the pump from the plant;
6.
remove the drainage cap (4-Fig.1) and drain out the water inside;
7.
refit the drainage cap back in place, taking care to make sure the O-Ring is positioned properly inside it;
8.
the water trapped in the delivery system downline of the non-return plant integrated in the system can flow back
only the moment the system is disconnected.
