Ø The strainer should be placed as low as possible beneath the waterline so that it does not
draw in any air. It should be placed far from the discards.
Ø Pierce the hull with a Ø 21mm hole saw.
Ø The streaks of the strainer must be placed towards the front of the boat to allow the water
to naturally enter by scooping during navigation.
Ø Seal the junction with the hull properly using polyurethane sealant or Sicaflex. Do not
forget to paint the submerged part with special underwater paint.
Ø The hull valve must remain accessible for maintenance operations.
Ø Seal the valve/strainer and valve/hose connections with Loctite 577.
Ø The pre-pump must also be installed below the waterline for better production and
must be easy to access.
Ø The pre-pump is equipped (at its suction) with a 3-way valve.
Ø On the 3-way valve : for seawater suction from the pre-pump (seawater inlet
valve side) the connection must be made with Tricoclair-type piping with an
internal Ø19mm and the other side of the 3-way valve (rinsing side) of internal
Ø15mm .
Ø The connection for rinsing with fresh water must be made with water from the
circuit of the pressurized fresh water unit.
Ø The discharge from the pre-pump to the block of pre-filters must be done with
Tricoclair type piping with an internal Ø15 mm.
Ø The valve handle must be swung to the seawater position (see Appendix 3 for
the 3 positions of the 3-way valve
Ø As an option, a fixing bracket is available to fix the pre-pump to a vertical wall..

Connections
Ø The prefilter must also be installed beneath the waterline to ensure a better
yield/output. It must be easy to access
Ø The fixing bracket is reversible to allow you to adjust the installation height.
Ø Piping connections must be made with Tricoflex Ø15 mm (inside diameter), for the
entire seawater system as well as the pressurized rinsing system
à Do not forget to fasten 2 stainless steel collars on each fitting.
Ø Allow a minimum of 3 cm below the filter body for the clearance of the tank when
opening it. A screw is provided for screwing / unscrewing it.
Ø A solenoid valve is mounted behind the pre-filter for automatic rinsing.
Ø Fasten two stainless steel collars on each connection, with the clamping heads
positioned opposite one another.
Ø This connection can be made by tapping under a sink, a washbasin as well as on the
path of pressurized cold water pipes.
Ø If the pipes are to pass through walls or be in contact with sharp corners, provide
protection against wear and friction by inserting them into a sheath or pipe of greater
diameter.

AC PRO AUTO COMPACT D90 à D200 v3.2 EN Page 10
3) Motor/Pump Block
Ø To ensure optimal production, the assembly of the high-pressure motor block must be
completed as low as possible in the boat, in a horizontal position and in an area protected
from water sprays.
Ø Use the 2 stainless steel legs under the 2 motors to fix the motor block. Leave a
few centimetres of wiggle room around it.
Ø Provide sufficient airflow for the ventilation of the motors.
Ø The connection of the prefilter outlet to the inlet of the pump on the suction-side
pump should be done using Tricoflex piping Ø 12mm (inside diameter) and 2
stainless steel collars at each connection.
Ø The connection of the pump's high-pressure head to the membrane inlet (red mark)
should be done using a high-pressure hose that is cut to size (follow closely the
assembly instructions in Appendix A2).

entire system.

AC PRO AUTO COMPACT D90 à D200 v3.2 EN Page 12
5) Membrane Block
Ø The membrane block should preferably be mounted horizontally (on the base or side).
A vertical position might lead to a yield/output loss over time.
Ø Fastening is done using self-tapping screws in the stainless steel brackets .
Ø It is necessary to sheath the pipe connecting the output of the high pressure pump
to the inlet of the membranes because of the vibrations, which might lead to leaks
if the pipe is attached or in direct contact with something.
Ø The installation of the high-pressure nozzles must be carried out according to their
assembly instructions (see Appendix A2).
Ø Put some Loctite or threadlock on the 2 male and female cones before tightening.
Ø Available as an option: 90° elbow high-pressure nozzle for the inlet and outlet of the
membranes .

Start-Up
1) Precautions before start-up
Mandatory:
Ø When using the device for the first time, after changing the filter, after the boat has
been grounded or stopped for a long time, you should flush the system using fresh
water by operating the three-way valve on the prefilter (see Appendix A3).
Purge the system for 1 minute: watermaker must be stopped and the pressure
regulator open (counterclockwise).
Ø Once the system is filled, put the valve back in seawater position (see Appendix A3).
➥
Note: If you are not going to use the watermaker at all for a month or more, we
recommend to either sterilize the membranes for storage (for a maximum duration of 6
months) or to rinse it out at least once a month.
Before starting the system back up, we recommend rinsing it out for two minutes (see
Appendix A3).
WARNING!
Before starting-up, check that the valves are open
.

AC PRO AUTO COMPACT D90 à D200 v3.2 EN Page 16
2) Starting-up the watermaker
➥Note : The fresh water yield depends on the temperature and salinity of the sea water
and the cleanliness of the 5 & 25 micron filters (in the pre-filter).
Automatic mode:
The AUTOMATIC product range is equipped with a motorized knob regulator to adjust the
pressure.
Ø Simply set the switch AUTO and press the START button or on the Mini-Command
remote press button (follow the procedure in paragraph 5).
Ø The pre-pump starts, the needle on the low pressure manometer rises in the green zone.
Ø The engine has started, the pressure regulator knob will automatically run to increase the
pressure to the orange zone of the pressure gauge, then gradually adjust it until it reaches
the green zone on the pressure gauge. This procedure takes about 2 minutes.

AC PRO AUTO COMPACT D90 à D200 v3.2 EN Page 17
➥Note : Too high a pressure setting stops the watermaker and turns on the red light. In
this case, decrease the pressure with the pressure regulation knob and repeat the
startup procedure.
The fresh water yield depends on the temperature and salinity of the sea water and
the cleanliness of the 5 & 25 micron filters (in the pre-filter).
Manual mode:
Follow the procedure below :
Ø Set the switch to MANUAL and press the START button
Ø The pre-pump starts, the needle on the low pressure manometer rises in the green
zone.
Ø Once the engine has started, gradually turn the pressure regulator knob to the right
to increase the pressure towards the middle of the orange zone then continue
gradually increasing the pressure until it reaches the green zone on the pressure
gauge. This procedure takes about 1 minute.
This pressure build-up procedure should last approximately 1 minute.

AC PRO AUTO COMPACT D90 à D200 v3.2 EN Page 18
3) Stopping the watermaker: without rinsing of the membranes
It is not necessary to rinse your membranes if you use your watermaker regularly.
Mode Automatique :
Follow the procedure below :
Ø Set the switch to OFF or on the Mini-Command remote press on , follow
the procedure on the paragraph 6).
Mode Manual :
Follow the procedure below :
Ø Set the switch to « OFF» or on the Mini-Command press on (optional,
follow the procedure on the paragraph 6).
Ø You can now lower the pressure regulator knob to the left (counterclockwise)
until the needle of the high pressure gauge is at the minimum.
Ø Once the knob has come to a stop, reopen the pressure regulator knob by
only ¼ of a turn (to the right).
Beyond 10 days without use, it is best to rinse the membranes before the
watermaker is started-up again (see manual rinse procedure in Appendix A3).
If watermaker is not used, the rinsing is to be renewed every month.
If the watermaker is not used completely, the membranes must be sterilized for storage
(for a maximum of 6 months).

AC PRO AUTO COMPACT D90 à D200 v3.2 EN Page 19
4) Stopping the watermaker : with automatic rinsing of the membranes
A rinsing must be carried out if the watermaker is not going to be used for more than
10 days.
Automatic mode:
After using the watermaker, do not turn it off.
Ø While the watermaker is still running, Start turning the knob of the pressure
regulator (counterclockwise) to engage the rinsing mechanism, the pressure of
the manometer will drop.
Ø The watermaker will then start the rinsing procedure. The green and yellow LEDs
on the control panel will light up, indicating that the rinsing procedure has started.
It lasts 30 seconds. When the procedure is complete, the green and yellow LEDs
will lights off and the only remaining indicator will be the flashing blue LED on
the switch . If you don't have a mini-control you can turn the switch OFF .
Automatic rinsing is the best way to rinse your system because it not only replaces
seawater with fresh water, but it also washes your pre-filter and allows discharge to the
sea through the suction through-hull all dirt and debris accumulated in the filters.
Is watermaker is not used, the rinsing is to be renewed every month.
If the watermaker is not used completely, the membranes must be sterilized for
storage (for a maximum of 6 months).
