Start-Up

1. Precautions before start-up
   WARNING! Before starting-up, check that the valves are open.
   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).
   Ø 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). Ø It is important to take into account the ampere capacity of the battery as well as the
   operating time. When using the system in 12 or 24V, you should not run it for more than 5 minutes without starting the boat engine.
   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).

Page 14

2. Starting-up the watermaker
   Automatic mode:
   The NAVIGATOR product range is equipped with a motorized knob regulator to adjust the pressure. Simply set the switch to 12/24V or 230V (or 120V), the pressure regulator dial will automatically go in 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 3 minutes.
   Once this procedure is done, your watermaker will start producing fresh water, whose quality will be checked.
   Manual mode:
   If you prefer, you can build the pressure manually. Manual mode can only be activated within the 10 seconds following the starting-up of the device. This will temporarily deactivate Automatic mode.
   Set the switch to 12 / 24V or 230V (or 120V). 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 pressure build-up procedure should last approximately 1 minute.
   Once this procedure is done, your watermaker will start producing fresh water, whose quality will be checked.
   The device will then reset back to Automatic mode for the next time you use it.

Note: The fresh water yield depends on the temperature and salinity of the sea water.

3. Stopping the watermaker: without rinsing of the membranes
   It is not necessary to rinse your membranes if you use your watermaker regularly. Set the switch to OFF, the watermaker will stop.

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).
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. After using the watermaker, do not turn it off. Start turning the knob of the pressure regulator (counterclockwise) to engage the rinsing mechanism, the pressure of the manometer will drop . The watermaker will then start the rinsing procedure. The green and yellow LEDs on the control panel will illuminate, indicating that the flushing procedure is started. The procedure lasts 30 seconds. Once it is complete, the green and yellow LEDs will turn off and the only remaining light will be the flashing blue LED on the switch . If you do not have a Mini Remote Control, you can turn off the system by position the switch to OFF.

5. Using the Micro Remote Control (optional)

STARTING YOUR WATERMAKER :

2 sec.

To start the watermaker from STANDBY and run it on DC power, press and hold for about 2 seconds.
To start the watermaker from STANDBY and run it on AC power, press and hold for about 2 seconds.
The BLUE LED of the button pressed will start to blink and the buzzer will acknowledge the operation with 2 `beeps’.
Upon release of the button, the watermaker will start.
The RED, YELLOW and GREEN LEDs will show the same indication as on the control panel of the watermaker.
The blinking speed of the YELLOW LED provides feedback of the water pressure in the system : faster blinking means higher pressure.
The BLUE LED that is lit shows if the machine is running on DC or AC power.
Once the production water is of good quality, the GREEN LED will light up.

Note : It is best practice to slowly build up water pressure inside the system in order to prolong the lifetime of your membranes. For that reason, should you plan to start your watermaker frequently using the Micro-Command we highly recommend to consider a machine with Automatic Pressure Regulation, like the DESSALATOR Navigator, Automatic or Pro-Auto series.

Operation
Membranes are delicate components
Reverse osmosis membranes must be carefully maintained as they are the most sensitive parts of your system. Follow the instructions given to avoid damaging them and voiding the warranty. The nominal production capacity of the watermaker is given for a temperature of 25°C for seawater and depend on the salinity of the seawater in your navigation area. Each degree below this given temperature decreases the flow rate by 2.5 to 5%.
Extremes temperatures
The membranes should not be exposed to temperatures below 0°C. Overpressure, caused by expansion resulting from freezing, can rupture the membranes and prevent the salt from being filtered out. The membranes must not be exposed to temperatures above 60°C, as high temperatures may also prevent salt from being removed.
Drying out of the membranes
After the first use, the membranes should be kept immersed in liquid, either in treated seawater, in a mix of fresh water and sterilizing solution or, temporarily, in fresh water (see Sterilization methods, Appendix A4).
Recommendations for use
The different quality and salinity level of seawater influence the yield of the membranes.
WARNING! Do not use this system in areas where the water is muddy or polluted and at the mouth of rivers or brackish water. This will prevent clogging the prefilter and damaging the membranes.

DUO NAVIGATOR-60 v2.6 (10/2023)

Page 19

Maintenance
WARNING! In case of risk of frost, we recommend emptying the flowmeter located on the control panel, disconnect the output pipe (blue) and blow or inject air into this pipe while alternating pressing on the small button of the solenoid valve located at the back of the control panel. You should also protect your membranes against the cold using blankets or insulation.

1. Membranes maintenance
   Over time, it is normal for the flow to drop by 10 to 15%. If yield/output is no longer satisfactory, you should consider replacing the membranes. The output volume of your watermaker is established within the first 24 to 48 hours of operation. The fresh water output depends on the salinity and temperature of the seawater, as well as on the working pressure of the membranes. Rinsing the membranes can improve the yield/output.
2. Rinsing frequency of the membranes
   It is therefore not necessary to rinse the membranes after each use. Rinsing them too often can lead to premature deterioration of the membranes. There are two methods to flush the system: one manual and the other automatic. Both methods use the water in the boat’s tanks. It is necessary to rinse the watermaker if it is not going to be used for several days.
   Reminder: All flushing procedures should be done with the motor/pump block off. The biggest enemy of membranes is pressurized fresh water.

DUO NAVIGATOR-60 v2.6 (10/2023)

Page 20

Manual Rinsing
There is a valve next to the prefilter. This valve is connected to the freshwater tank of the boat. When turned, it will automatically start the boat’s freshwater system and send fresh water from the tank to the watermaker.
1. Do not put the watermaker on “ON”; leave it in its “OFF” position. 2. Turn the pressure regulator all the way in the counterclockwise direction. 3. Turn the fresh water inlet valve, located next to the prefilter, for 2 minutes. The boat
pump will start and fresh water will flow into the watermaker.
Automatic Rinsing
See page 16 “Stopping the watermaker: with automatic rinsing of the membranes”
3) Sterilizing the membranes
When should the membranes be sterilized?
Under normal circumstances, a monthly and regular rinsing of the membranes is enough for their maintenance. If you do no use the watermaker for a while and cannot perform a monthly rinsing, membrane sterilization is necessary. The protective effect of sterilizing does not exceed 6 months. The sterilization should never be renewed more than twice a year but should include, between these two operations, a mandatory rinse with fresh water. An excessive concentration of sterilizing solution can corrode the membrane heads. We recommend the sterilizing cartridge ST2 and our specified dose of sterilizing solution, adapted to your system. Failure to comply with these recommendations or use of another sterilizing solution void the warranty.

DUO NAVIGATOR-60 v2.6 (10/2023)

Page 21

Membranes sterilizing procedure
1. Easy method using the ST2 sterilization cartridge (reusable): We have developed a sterilization cartridge that greatly facilitates handling. The instructions for this cartridge are given in Appendix 4.
2. Manual method without the ST2 sterilization cartridge: With the watermaker turned off, thoroughly rinse it for 10 minutes with fresh water using the 3-way valve on the prefilter. Pour the sterilizing product (whole bag) into a bucket containing 8 litres of water. Uncouple the seawater inlet pipe and immerse it in the bucket. Start the watermaker without increasing the pressure until the bucket is empty. Once the bucket is empty and the operation completed, reconnect the pipe.
3. Method using a garden sprayer: Pour the sterilizing product (whole bag) into a bucket containing 8 litres of fresh water and mix everything together. Fill the garden sprayer with this mixture and increase the pressure to 3 or 4 bar. Then inject the sterilizing solution at the inlet of the membranes (red mark side).
Note: Before using the watermaker again simply rinse it with fresh water for a few seconds, using the 3-way valve located on the pre-filter, in order to eliminate the sterilant.
4) High-pressure pump
The high-pressure pump is half filled with oil to the level indicated on the gauge. The oil used in the pump is a 15W40 or 20W40 multigrade oil. You not exceed the level (as shown on the gauge). The oil does not need to be change over time.

Appendix A1: How do watermakers work?
How does reverse osmosis work?
Pressurized seawater enters the membranes which, similarly to “molecular sieves”, only let the fresh water molecules pass. Most of the dissolved solid particles do not cross the membranes. These residues are evacuated with the discharge water. Reverse osmosis extracts 99% of impurities. The drinking water produced by your reverse osmosis system can be consumed. If stored in your tanks you can, if needed, treat this water with commercially available products. Make sure to follow the manufacturer’s dosage instructions. We sell a mineralizing cartridge if you plan to drink the produced fresh water long- term.
How does your watermaker work?
Seawater is draw in through the inlet valve of the thru-hull. It then passes through the 5micron prefilter. The filtered water is then pressurized in the membrane tube by the highpressure pump (operating pressure is in the green zone of the pressure gauge). The pressurized water passes through the orifices of the membrane surface, freed from the salt and bacteria, which are poured back into the sea along with the remainder of the solution used to self-clean the membranes. The now fresh water goes through a probe measuring the salt content: if the water is sufficiently desalinated, the 3-way valve is automatically switched to direct the fresh water to the tanks. On the other hand, if the salinity sensor registers a salt content that is too high (conductivity greater than 1,000 Siemens), the valve will reject the output water at sea. The amount of drinking water being produced is controlled by a flowmeter located on the control panel. The fresh water production capacity is given for a seawater temperature of 25°C. Yield is reduced by 2.5 to 5% per degree Celsius of temperature drop.

Appendix A4: Instructions for the Sterilizing Cartridge
With the watermaker OFF:
Ø Close the seawater inlet valve. Ø Open the sterilizing cartridge: be careful not to lose the O-ring. Ø Remove the top screen. Ø Place the foam at the bottom of the filter. Ø Pour the sterilizing powder into the cartridge. Ø Replace the top screen and close the cartridge. Ø Check that the seal is correctly in place. Ø Remove the 5-micron cartridge from the prefilter.
Remove the 5-micron cartridge from the prefilter

Ø Replace it with the sterilizing cartridge
Replace the 5-micron cartridge with the ST2
sterilizing cartridge

Ø Turn the rinsing valve to the fresh water position (see Appendix A3) so that the sterilizing powder mixes with the water, the valve must be closed before all of the powder disappears (there must be a little left inside the bowl).
Ø Please note that this procedure is very quick. The watermaker should not be turned on Ø Duration of sterilization: 6 months maximum (to be repeated beyond that)
Important: Before the next start-up, rinse the system out using fresh water for 10 minutes. Remove the ST2 sterilizing cartridge and replace it with a 5-micron cartridge.
WARNING! The ST2 cartridge can be reused.
