All the hydraulic connections (to exception of the fresh water production) have to be realized
with a 16 mm. int. diam. hose and a ½” holder. The hydraulic section that is continuously
under consistent pressure is the pump outlet – 5 m. filter – watermaker inlet connections . For
this section is necessary to use a good quality PN 15 min. reinforced hose. An inadequate hose
could burst, jeopardizing seriously the safety of the boat. The hydraulic connections are:
Low pressure
max 3 bar
-connections sea water inlet- net filter -
backflow valve inlet.
-connection watermaker’s exhaust
discharge - drain outlet.
