2.5 Hydraulic diagram
For all the hydraulic connections (except the fresh water production pipe) use a spring type 16
mm. internal diameter hose (not furnished) and a ½”fittings. The hose must be min. PN 5 (it
must work safely with a pressure up to 5 bars).
IMPORTANT:
Sea water inlet connection.
Install the non return valve as low as possible and close to the net filter.
The hose laying must be as short and linear as possible.
Discharge connection.
Create a Swan neck upward (20 cm. above the watermaker) when the drain outlet on the vessel
is positioned below the watermaker unit, in order to guarantee a water head.
Connection to the fresh water tank (use the furnished blue 6X8 hose).
The connection has to be made using the small hose supplied with the equipment. The
connection has to be made to the upper side of the tank, on a ¼” outlet if available.
It is possible, in case of metal tanks, to make a ¼” threaded hole to connect the supplied male
connector. Another option is to Tee into the tank air vent hose.This is only possible if the
breather pipe section is more than 16 mm. dia. There are no particular limits on the connection
length.
