2. How to install the watermaker:
2.1 Sea water inlet
Sea water inlet valve
:
The strainer should be positioned as low as possible below the waterline
and as far as possible from the deck waste oulet. Drill the hull

21mm.
The grooves on the strainer should be facing forward (towards the bow)
for maximum water intake when the boat is moving forward. Please seal
watertight with Rubson mastic or Sicaflex and ensure that the immersed
part is painted with underwater grade paint.
The hull valve should be accessible for maintenance. Make the valve /
strainer and valve / hose connector watertight using 577 Loctite or Teflon
tape.
Cartridge pre-filter
:
The pre-filter should also be positioned as low as possible below
the waterline and it should remain accessible. The mounting
bracket is reversible, which facilitates the height positioning. The
hose connection must be done with 12mm inner diameter
Tricoflex for all the sea water circuit and the pressurized rinsing.
Don’t forget to place two stainless steel collars on each
connection. 5cm space should be left below the filter body to
allow the filter basin to be removed. A wrench is supplied to
dismantle the filter. The fresh water pressurized rinsing must be
connected to the output of your board pump. An electro-valve is
mounted on the output (diam. 12) for automatic rinsing. It can be
connected under a sink, a wash basin or on the way of
pressurized cold water hoses. The valve handle must be
positioned to the front when the water maker is working. For a
manual rinsing, please move the valve handle to the back.
When replacing the filter cartridge, please check that the O-ring
seal for the basin is secure and that the bleeder screw is
tightened and fill the circuit without pressure with fresh water
again for 3 to 4 minutes, put then the handle to the front.
Connections:
Hull valve / three-way valve, Pre-filter / pump, Fresh water / three-way valve
The sea water inlet valve should be connected to the pre-filter using a tricoflex hose of inner

12mm, for sea water circuit and rinsing under pressure. Mount two jubilee clips at each joint, with
their tightening heads positioned diametrically opposite on the hose. Connect the pressurized fresh
water from the water oulet to the three-way valve. This connection can be made under a sink,
wash basin or anywhere on the length of the pressurized fresh water pipe. When operating in sea
water mode, the valve handle should be positioned in line with the filter (see photo above).
Recommendation:
If the pipe must pass through dividing walls or touch sharp edges, use an insulating pipe or tube
superior to the pipe diameter to protect it against wear and friction.
