❶ Start your engine and let it warm up, adjusting it until it’s running at a steady speed.
►►►Never run your engine above your
maximum allowable engine speed.
It’s critical that the pressure of the
membrane remain constant; because
this is directly aected by your engine
speed, do not vary the engine RPM
while running your watermaker.
❷ When the engine has reached operating
temperature, turn the SeaWater valve to the
“Seawater Intake” position and turn the Fresh
Water valve to the “FlushTank” position. (See
Figure 1.)
❸ Place the hose labeled “To ush tank” into a clean
5 gallon bucket.
Before starting your watermaker:
• Oil, chlorine and other chemicals will do permanent damage to your watermaker
membrane. Always conrm that your feed water source is free of chemicals before
starting the system.
• If the watermaker has been in storage and this is the rst start-up since pickling the unit,
follow the normal start-up procedure, but discard all product water for the rst 15 - 20
minutes of operation to ensure that the biocide solution has been completely ushed
from the system. Ingestion of the solution will cause gastrointestinal issues.
My maximum allowable engine speed:
RPM
(Determined during installation; refer to chart on page 25 .)

❹ Turn the Pressure Adjustment Needle Valve counterclockwise 2 times to decrease pressure.
❺ Turn on the Seawater Lift Pump using the switch on the panel labeled “Seawater Lift Pump.”
❻ Verify the following:
• Water is running through the system and is being discharged overboard;
• The Membrane Pressure Gauge on the right side of the panel indicates zero pressure;
• The engine is still running smoothly at a steady speed
❼ Start the High Pressure Pump by using the switch on the panel labeled “H.P. Clutch.” You should see
the ow of water through the system increase.
❽ Let the watermaker run for a few minutes to clear any air from the system and to be sure that a
steady ow of water is being discharged overboard.
❾ Very slowly, turn the Pressure Adjustment Needle Valve on the panel in a clockwise direction until
the pressure increases to 700 psi. Let the system stabilize. Product water should now be owing into
your bucket.
❿ Verify that everything is running properly and that the pressure is being maintained at 700 psi. Now
turn the Pressure Adjustment Needle Valve in a clockwise direction again to increase the pressure to
its nal rate (the actual pressure will depend upon water temperature, salinity, etc.).
►►►Never go above 850 psi.
Sea Clear Watermakers™ Manual -Version 3-B Page 11
Your watermaker output will vary based on the temperature and salinity of the sea water. The
properties of the water will change based on temperature; the rule of thumb is the colder the
water, the lower the output at a given pressure.The same is true for a higher salt content; in
warmer climates, a higher output can be expected.
It is critical that the pressure remain constant at 800 PSI at all times. Do NOT increase the
pressure to attempt to achieve a higher product output.

⓫ Let the bucket ll with water; while you’re waiting, take a moment to do a routine check for any leaks
in the system. When you are satised with the product water, turn the Fresh Water valve to the “To
storage tank” position (valve should be vertical). Remove and coil the hose and put the full bucket
aside for use during shut down.
⓬ Check the Membrane Pressure Gauge on the right side of the panel occasionally to verify that the
pressure is constant.
⓭ Monitor the level of water in your tank. When the tank is full or when you are nished making water,
proceed to the shut down process on the following page.
Sea Clear Watermakers™ Manual -Version 3-B Page 12

❶ When your tanks are full or you are nished making water, slowly turn the Pressure Adjustment
NeedleValve counterclockwise. The pressure on the gauge above should decrease to zero PSI and
the product water should stop owing.
❷ Turn the Fresh Water valve to the “Flush tank” position (valve should be horizontal), so that it’s ready
for the next time you make water.
❸ Put the hose labeled “Flush water intake” into the bucket of product water (set aside during start-up)
and turn the SeaWater valve to the “Flush water intake” position (valve should be horizontal).
❹ Turn o the Seawater Lift Pump using the switch on the panel labeled “Seawater Lift Pump.”
❺ The water will ow from the bucket back through the system; let it run until the bucket is almost
empty.
❻ Turn o the High Pressure Pump using the switch on the panel labeled “H.P. Clutch.”
 ►►►Do not let the pump run dry for more than a few seconds as this will damage your system.
Upon shut down, organic matter will remain in the system, which will cause microorganisms
to grow that can clog/damage your membrane. Flushing the system with product water after
shut down eliminates most organic matter and keeps your membrane clean.
►►►If your watermaker will be inactive for more than 7 days, the membrane must be
pickled (see “LongTerm Storage”).
Sea Clear Watermakers™ Manual -Version 3-B Page 13
Never let the pump run dry and never turn o the Seawater Lift Pump while the High Pressure
Pump is running and the Seawater valve is in the “Seawater Intake” position. When shutting
down the system, always switch the Seawater valve to the “Flush water intake” position
before turning o the Seawater Lift Pump.

If you do not intend to use your watermaker again within the next 7 days (5 days in hotter climates), the
watermaker should be pickled. Pickling introduces chemicals into the system to prevent the growth of
microorganisms that will damage the membrane.
The pickling process will preserve the membrane for up to 6 months. If the watermaker will be inactive
for longer durations, the pickling process must be repeated every 6 months.
❶ Using the 5 gallons of product water made during start-up*, add 5 tablespoons of sodium
metabisulte to the bucket and mix until dissolved. (Sodium metabisulte is readily available
wherever you nd beer brewing supplies.)
❷ Put the hose labeled “Flush water intake” into the bucket and turn the Sea Water valve to the “Flush
water intake” position (valve should be horizontal).
❸ Turn o the Seawater Lift Pump using the switch on the panel labeled “Seawater Lift Pump.”
❹ The pickling solution will ow from the bucket back through the system. When the bucket is empty,
let the watermaker run for an additional 5 seconds before shutting down.
❺ Turn o the High Pressure Pump using the switch on the panel labeled “H.P. Clutch.”
►►►Do not let the pump run dry for more than a few seconds; this will damage your system.
If the watermaker may be exposed to freezing temperatures, antifreeze must be introduced
into the system. Please follow “ColdWeather Storage” procedure on the next page.
Sea Clear Watermakers™ Manual -Version 3-B Page 14
* If for any reason you are unable to operate the watermaker (e.g., during haul out) and you
do not have 5 gallons of product water available, you may use clean tap water instead.
However, the tap water must be run through a charcoal lter rst to eliminate all chlorine,
as this will damage your membrane.


If the watermaker will be exposed to freezing temperatures, it is necessary to introduce antifreeze.
Propylene glycol antifreeze (also known as RV antifreeze or potable water antifreeze) can be used for
cold storage or storage up to 1 year.
❶ Starting with the watermaker o, ll your 5 gallon bucket with propylene glycol antifreeze.
❷ Put the hose labeled “Flush water intake” into the bucket and turn the Sea Water valve to the “Flush
water intake” position (valve should be horizontal).
❸ With the engine at operating RPM, turn on the High Pressure Pump by using the switch on the panel
labeled “H.P. Clutch.”
❹ Watch the brine dump and turn o the High Pressure Pump as soon as you see antifreeze.
►►►Keep a close watch on the 5 gallon bucket to be sure it does not run dry.
►►►Depending upon Seawater Lift Pump installation, it may be necessary to drain water from hoses
and lift pump before exposing to freezing temperatures.

►►►Use only 5-micron 10” polyester lter elements, such as Katadyne 8012861. These can be found
at most marine and water supply stores.
Pre-lters should be replaced regularly. To determine the status of your Pre-lter element, use the Pre-
lter Pressure Gauge on the Control Panel. This gauge should stay at or above zero PSI when the system
is in operation. If the gauge shows a negative pressure or a vacuum, it’s time to replace the element.
Replacement Procedure
❶ Shut down the system and ensure that the Sea Water Lift Pump is OFF and through-hull is closed.
❷ Unscrew the Pre-lter Housing and remove the Pre-lter element.
❸ Discard the used element and install a new 5-micron polyester element.
❹ Reassemble by securely screwing the Pre-lter Housing back together.
❺ When restarting the system, be sure to check the Pre-lter Housing for leaks.

Your watermaker system includes an AR North America High Pressure Pump (see data sheets on the
following pages). Designed for long life, the pump should provide years of trouble-free operation if
maintained and inspected regularly.
During installation, the gear case was lled with 9.81 oz. ISO 100 - NA 30 weight hydraulic oil and the
bolts and belts were adjusted. It is good practice to inspect the belt and check the gear case oil every 20
hours of operation.
