Outboard powered boats are one of the fastest growing segments of the
Marine industry today. Gasoline powered outboard motors present unique
safety challenges for electrically controlled marine equipment like
watermakers. With these challenges in mind, Spectra has designed the rst
watermaker specically congured for this excing class of boats, the Bimini
300.
The Bimini is the rst watermaker to be cered Ignion Protected for use on
gasoline powered boats. Non-sparking switches and a state-of-the-art
brushless DC motor are ulized to make sure all components comply with the
strictest federal guidelines. This safe, convenient system is versale, modular
and easily maintained.
The Bimini 300 is also fully automated with the Spectra Connect system making
it the simplest watermaker ever to operate and maintain, as well as allowing
mobile access and control from a phone, tablet or computer. Data logging, Fill
Tank, Auto Flush, and built-in Maintenance Interval schedules put the Bimini
300 into a class of its own.
The Spectra Bimini 300 greatly extends the range and versality of the modern
outboard powered vessel.

Thank you for your purchase of a Spectra Bimini 300 system. When properly installed and
maintained, it will provide years of trouble free service. Professional installaon is strongly rec-
ommended. Like any piece of mechanical equipment, the system will require inspecon and
service, so plan ahead for service access and install “service loops” in cabling. If a dealer is in-
stalling the system for you, review the locaon of the components to ensure the installaon
will meet your approval upon compleon.
Bimini Installation Quick Start
Important Details for Installer
1. The system must have a dedicated sea water inlet to guarantee a constant ow of water to
the system. The inlet should be as low in the boat as possible with a dedicated, forward-facing
scoop-type thru-hull ng.
2. Both the Bimini 300 feed pump module and the Clark Pump/Membrane module must be
installed in a well venlated compartment where temperatures will not exceed 113°F (45°C).
Many engine compartments exceed this temperature when underway. Warranty will be void if
the installaon does not meet this requirement.
3. Follow the wire gauge charts in the instrucons! Using larger wire than specied is accepta-
ble.
4. If you are separang the Clark Pump/membrane assembly, please review the high pressure
tube assembly instrucons. Improper assembly will cause failure!
5. Run, test, then sea trial the complete system before assuming it is operaonal. If the boat is
in fresh or dirty water, see Dry Tesng the System. Aer tesng, make sure the ush cycle op-
erates properly. The water going overboard at the end of the ush should measure <1000 PPM
Total Dissolved Solids.
6. The Spectra Connect control must have DC power connuously to achieve the full benets
of the fresh water ush system. The domesc fresh water pressure must be on and the fresh
water tank level maintained. Calculate about 7 gallons (27 liters) per ush.
7. The Spectra Connect control must be de-powered (DC power o) aer the system is pickled
or winterized.
8. Spectra dealers are responsible for educang the vessel owners on the operaon and
maintenance of the system. Please walk through the enre installaon with our customer.
9. The equipment owner should ll out the warranty card or register online.

Unpack the system and inspect it for damage during shipping. Freight damage must be report-
ed to the carrier within 24 hours.
Refer to the shipping list for your system to ensure you received all of the components listed.
Do not discard any packaging unl you have found and idened all of the parts. The small
installaon parts are listed on the kit list.
Warning! We will not be held responsible for shortages that are not reported within thirty
days of the ship date.
Study the system layout diagram, component photos, and descripons before beginning in-
stallaon.
Lay out the system. Before starng the installaon idenfy where each module and compo-
nent will be placed. Ensure that there is enough clearance around the components for remov-
al of lters and system service. Make sure you have adequate tubing and hose before starng.
Addional parts may be ordered.

Installation Basics
• Read the direcons!
• Avoid ght hose bends and excessive runs.
• Use heavy gauge wire.
• Install feed pump module as low as possible.
• Boost pump module must be installed below the waterline.
• Use a dedicated thru-hull with scoop-type strainer.
• Do not mount components over electrical devices.
• Avoid geng dirt or debris into the piping or hoses during
assembly. A small bit of debris can stop the system!
Thru-hull Locaon: The system must be connected to a dedicated 3/4” to 1” forward-facing
scoop-type intake thru-hull and seacock.
Install the thru-hull intake as far below the waterline and as close to centerline as possible to
avoid contaminaon and air entering the system. Do not install the intake close to, or down-
stream of, a head discharge, behind the keel, stabilizer ns, or other underwater xtures.
Thru-hulls in the bow area are suscepble to air intake in rough condions. Sharing a thru-hull
can introduce unforeseen problems such as intermient ow restricons, air bubbles, contami-
nants, and will void the warranty. For racing boats and high speed boats traveling above 15
knots, a retractable snorkel-type thru-hull ng is preferred because it picks up water away
from the hull.
The brine discharge thru-hull should be mounted above the waterline, along or just above the
boot stripe, to minimize water li and back pressure.
Double clamp all hose connecons below the waterline.
Avoid restricons or long runs on the enre inlet side of the plumbing from the thru-hull to the
feed pump module.
Secure the piping away from moving objects such as engine belts and hatches. Prevent chafe on
the tubing as required. Test and inspect all piping and hose clamps aer several hours of opera-
on.
Pipe Fing Instrucons: To seal plasc-to-plasc ngs, wrap 6 to 8 layers of Teon tape over
their threads. Hold the ng in your le hand and ghtly wrap the threads clockwise. For
smoother assembly, do not tape the rst (starng) threads.
Wiring
• Pay aenon to wire size or system performance will be impaired
• Perform wiring to UL, ABYC, CE or applicable standards

Feed Pump Module
Mount the feed pump module on a vercal surface, up
to 3-feet (1.0M) above the waterline. It is preferable to
mount as low as possible. Locate in an area that allows
easy access to both the lters, and the le and right
side of the enclosure (3 inches or more). Keep future
maintenance in mind when choosing a locaon, and do
not mount above water-sensive equipment. The feed
pump has overheat protecon and will not operate
properly at ambient temperatures over 113°F (48°C).
Sea Strainer and Boost Pump Module: Mount close to the
intake through-hull, below the waterline, in a locaon that
can handle water spillage during service. The boost pump
power cable will connect to the feed pump module.
Fresh Water Flush Module: The fresh water ush module may be
located in any convenient locaon near the feed pump module. It
should be mounted with the lter housing vercal and accessible,
with 2” below the housing for lter changes. Do not install over
electrical equipment. The unit contains the charcoal lter, a
solenoid shut o valve, and a ush water ow regulator.

Salinity Probe (under)
Diversion Valve
The 1/4”(6mm) product water tubing is pre-plumbed from the membrane into the electric diversion
valve. The diversion valve will reject product water into the overboard brine stream unl the
Connect controller determines the product water is below 750 PPM salinity. Once below 750 PPM,
the Connect controller opens the diversion valve and product water is diverted into the fresh water
tank. The salinity probe must be mounted in a vercal posion with the cable coming out the
boom. If the Clark Pump/Membrane Module is mounted vercally or upside down the diversion
valve/probe assembly MUST be remounted in the proper orientaon.
For plumbing to the fresh water tank, see the John Guest ng assembly diagram on the next
page.
Product to tank: Route the product water into the top
of a vented tank, or a tee in the water tank ll hose.
DO NOT feed into a vent line, manifold, or into the
boom of the tank. Bladder tanks will create too much
back pressure. There must be no restricon or back
pressure whatsoever in this piping.

Oponal Z-Ion Protecon System
The Z-Ion, developed by Spectra, protects the enre system from fouling for extended periods
without fresh water ushing or storage chemicals (pickling).
The Z-Ion achieves this end by introducing a stream of metallic ions into the fresh water ush
water, thus ooding the enre system with ions that prevent biological growth for up to thirty
days. If you are going to let your system sit idle for longer than thirty days, you will sll need to
treat it with SC-1 storage chemical or propylene glycol.
The Z-Ion will not prevent freezing, so in freezing climates pickling with propylene glycol is sll
required. Even with the Z-Ion there may sll be cases when you need to pickle your system
with SC-1 storage chemical or propylene glycol, so we recommend you carry one of these
products at all mes.
If your system was ordered with the Z-Ion, it will require only some basic wiring and
commissioning, laid out in the following pages.
If you didn't order you system with the Z-Ion, it can be retroed to any Spectra system.
NOTE: Contact Spectra for more informaon at: techsupport@spectrawatermakers.com

The Z-Ion should be energized at all mes, but will only consume power when operang. Upon
inial power-up the LED will ash red/green and then will turn solid green.
Follow the instrucons for Normal Operaon and Fresh Water Flush. For treatment with the
Z-Ion, the process is idencal, only the Z-Ion will release silver and copper ions into the ush
water when you turn on the generator with the on/o switch. Turn on the ion generator at the
same me that you open the ush valve.
The operaon cycle begins and the LED will ash green/amber. The cycle will connue unl you
turn o the ion generator or the adjustable mer mes out (factory set for 15 minutes).
Turn o the ion generator at same me that you close the ush valve. If you forget to turn o
the ion generator, the Z-Ion will me out aer 15 minutes, so no harm will be done to the unit.
If the voltage is out of range, below 10V or above 56V, the LED will ash red every two seconds
and the unit will shut down.
Each fresh water ush with the Z-Ion will protect your watermaker for up to 30 days, aer
which the process must be repeated.
Aer 720 cycles the service light on the front of the control box will light up, indicang that the

If a 2nd Tank Level Sensor is going to be installed, it should be installed at the
base of the second tank. If monitoring 2 water tanks, they must be isolated
from each other with a valve to read properly.
The wiring connecons for the second Tank Level Sensor are located inside the
Spectra Connect control box. See System Sengs secon of this manual for in-
strucons on enabling the second Tank Level Sensor.
See the Tank Level Calibraon (pg. 28) in the Commissioning secon of this

Optional Tank Level Sensor Installation
Route the 3 conductor cable back to the Spectra Connect control board at the feed pump
module. Extend the wires as necessary. If you must extend the wires beyond 50’ contact the
factory to ensure proper operaon.
Connect the Tank Level Sensor cables to the 3 conductors label Tank Level Sensors at the feed
pump module. Polarity must be maintained!

New System Start-Up and Testing
Use this procedure when starng a new watermaker for the rst me and whenever the
system contains preservave or cleaning chemicals.
Avoid running the system if the vessel is in contaminated water, such as a dirty harbor or
canal. The system should be fully run tested before leaving on an extended journey. It is
preferable to sacrice a prelter by tesng the system briey in turbid water rather than
waing to get oshore to discover a problem or deciency in the installaon. If the locaon or
weather prevents proper tesng refer to the secon Dry Tesng with an Arcial Ocean.
1. First Check That:
• Seacock is open
• Toggle switch on the Feed Pump
Module is in the Run Auto posion
• Domesc fresh water pressure system
is on.
2. Open pressure relief valve 1/2 turn and remove the
Green Tag and washer!
3. Turn on the power to the system and the Spectra Connect screen will display, “Has the
system been stored with chemicals?” Press ‘Yes’, to start the Purge sequence. Note: The
watermaker will shut down if the pressure relief valve is le closed during the Purge mode.
• Alarm will sound
• Display will read “Has the
system been stored with
chemicals?”
• Conrm the Pressure Relief
Valve is open
• Press ‘Yes’ to start the Purge
sequence
Warning! Damage may occur if the purge sequence is bypassed and
the membrane is pressurized with storage chemical in it.
33
Note: If you must stop the purge sequence for any reason, the control will default back to
the beginning of the purge mode to protect your system.
5. Aer the purge sequence the display will alarm with the message “Close pressure re-
lief valve.” Close the valve and proceed by pressing Ok to resume the Purge Cycle.
If the system is new from the factory, or stored with Propylene Glycol, addional purging me
may be required.
6. The system will now run under pressure and
desalinate water. This mode diverts the product water
overboard in case there is any residual chemicals in
the membrane. Carefully inspect for leaks over the
enre system! Shut down the system and repair any
leaks you nd.
Check the strainer and the brine discharge for water ow. The system should fully prime
within 60-90 seconds and all air should be out of the feed water hoses. The feed pump will
sound smooth.
There should be no bubbles anywhere in the intake hoses. If the feed pump connues to
sound rough, nd the reason before connuing! Inspect the system for leaks.
4. The system will start purging and the display will
show the progress and me remaining
New System Start-Up and Testing - Cont.
7. Aer the Product Purge cycle completes, the system will prompt to Restart, then advance
to the Main Menu. If this is a NEW INSTALLATION, connue to the Calibraon Instruc-
ons to nalize the installaon. If you are pung your watermaker back into service,
your system is now ready for use.

Dry Testing with an Artificial Ocean
If it is not possible to test run the system with the boat in the water, you may test the system
with an arcial ocean. You will need 1.3 lbs. of non-iodized salt (rock salt, sea salt, or aquarium
salt) to make a 5 gallons (33 grams of salt per liter) of water that is about 33,000 PPM salinity
(average seawater salinity). Make sure the domesc water system is powered up and the boat’s
tank has at least 60 gallons (230 Liters) of water to purge the storage chemicals from the system.
Conrm that the charcoal lter is installed in the feed pump module, and the domesc water
line is connected.
1. Open the pressure relief valve on the Clark Pump. Remove the green tag and spacer.
2. Power up the system. When the Spectra Connect displays “Has the system been stored with
chemicals?”, select “No” to bypass the purge mode.
3. Press the Fresh Water Flush buon to run a full ush cycle. Do this six mes to purge the
storage chemicals, a 36 minute process.
4. Replace the brine overboard hose with the brine service hose per gure 1.
5. Push the Fresh Water Flush buon again to ll the bucket with fresh water from the brine
discharge service hose (hose aached to Clark Pump). Press Stop when the bucket is full.
6. Mix the salt to the proper proporon or use an aquarium hydrometer to adjust the salinity
level to a specic gravity of 1.025.
7. Remove the fresh water ush hose from the fresh water ush module or Z-Ion at the Quick
Connect ng, and connect the intake service hose, per Figure 2. Disconnect the product
tube from the diversion valve, and using another small piece of tube, route it into the bucket.
8. Push the Start buon, then press Auto Run and program the Connect to make 10 gal (38 L)
of water, roughly 40 minutes of operaon.
9. Allow the system to prime and then close the pressure relief valve. The system should build
pressure shortly and start making water, with the brine and product water recombining in
the bucket to be cycled again. This will gradually heat the water. Do not let the water tem-
perature exceed 120 deg. F (49 deg. C).
10. Run the system under pressure, checking for proper operaon and leaks. Aer tesng the
system, re-install the brine discharge hose, product tube, and fresh water hose from the
strainer. You can now ush the system by pressing the Fresh Water Flush buon.

4. The Filter Condion has now been calibrated to match your installaon.
1. During the calibraon sequence the system will automacally start, begin to make water
for several minutes and then shut itself down. Make sure that the lters have been re-
placed for new, the strainer is clean, and all thru-hulls are open before proceeding.
2. Follow the steps in Figures 1—4 below to iniate the Calibraon Sequence.
Sensor Calibration
Many of the sengs on your system have been pre-calibrated during standard factory tesng,
however, there are a few sengs that will vary based on the installaon, vessel, and other
onboard condions. If the system has just been installed you must calibrate the Prelter
Condion before proceeding.
This procedure does not need to be done with each lter change under normal operaon, it
should ONLY BE DONE IF THE FILTER CONDITION WON’T RESET TO 100% WITH NEW FILTERS
AND A CLEAN/NEW STRAINER SCREEN.

Adjustments for your Bimini 300 are typically calibrated from the factory to ensure that sea
water is thoroughly ushed out of the watermaker using the least amount of fresh water.
However, due to dierent lengths of hose runs, dierent rates of ow, and dierent pressures
in shipboard fresh water systems, the ush duraon should be opmized for your boat. The
ush cycle is adjusted with 2 sengs: the pump speed and the ush duraon.
Check the pump speed
1. Close the thru-hull for the raw water inlet.
2. Push the Fresh Water Flush buon. The ush valve will open and the feed pump will start
at Flush Speed. If the ush completes normally, then the Flush Cycle is set properly.
3. If the display alarms ‘Service Prelters’ then the fresh water pump is not supplying enough
water, and the feed pump needs to be slowed down.
Slowing down the pump during a Fresh Water Flush
You can slow down the feed pump from the Spectra Connect Display’s Dealer Access Sengs.
Logging into the Dealer Access Sengs is outlined in the Spectra Connect Programming secon
of the manual,
Once in the Dealer Access sengs navigate the screens as follows:
Bring down the Fresh Water Flush down 0.5 (for example from 2.9 to 2.4) and preform another
test. If you sll get the alarm repeat this process unl the Bimini ush speed matches that of
your fresh water system and you no longer are received an alarm.
Once you’ve adjusted the speed correctly, the speed controller will stay programmed for this
speed during fresh water ushes.

WARNING: NEVER RUN YOUR WATERMAKER UNATTENDED. EQUIMENT CAN BE SERIOUSLY
DAMAGED, AND IT IS POSSIBLE TO SINK THE VESSEL! Use extreme cauon when operang in
Auto Fill mode!
In Auto Fill Mode the Spectra Connect will automacally ll your water tank, stop itself, fresh
water ush, return to Auto Store mode with the ush interval mer running, and then turn
itself on again to ll the tank as soon as the water level drops below the Tank Low Switch with
no addional user commands.
Addionally, if power is interrupted at any stage of operaon, the Spectra Connect will return
to Auto Fill mode, ensuring that your tanks will always have water.
47
Warning! Proper understanding of the Spectra ush system and the vessel’s fresh water system is
mandatory for extended use of Auto Store. The ush cycles must not be allowed to drain all the
fresh water from the tank or damage to the vessel’s systems and the watermaker may occur.
The Auto Store funcon ushes the watermaker at programmed intervals. As long as the
watermaker is ushed with fresh water every 5 days (30 days with the Z-Ion) you need not store
the system with chemicals.
• Make sure there is enough water in the fresh water tanks to supply the watermaker for more
than the expected me of operaon in the Auto Store mode. If there isn't enough fresh water
in your tank, seawater will be drawn in and the system will not be ushed with fresh water.
The Bimini 300 requires about 7 gallons (26 liters) for each ush. The boat’s pressure water
supply must be on and stay on while the system is in Auto Store mode. If these condions
cannot be met, then pickling with SC-1 storage chemical or propylene glycol is preferable.
• Make sure the pressure relief valve on the Clark Pump is closed.
• The system must be connually powered on during the Auto Store mode. Turning o the
power will disable the automac fresh water ush and damage may occur.

Maintenance
General
Periodically inspect the entire system for leakage and chafing. Repair any leaks as soon as you
find them. Some crystal formation around the Clark Pump blocks is normal. Wipe down any salt
encrusted areas with a damp cloth.
Watermakers are at their best when run regularly. Biological fouling in the membrane is more
likely when a watermaker sits idle. A warm environment will cause more growth than a cold en-
vironment. A fresh water flush every five days (30 days with the Z-Ion) will greatly reduce biolog-
ical growth, but may not stop it completely. The Z-Ion system protects the membrane from bio-
fouling without the use of storage chemicals.
The Seawater Strainer
The seawater strainer’s stainless steel element should be inspected, removed, and cleaned as
needed. Ensure that the thru-hull is closed before disassembly and the gasket is in place before
reassembly. When the system is put into storage, remove the strainer, rinse with fresh water,
and reassemble dry to impede corrosion. Check frequently during operation.
The Prefilters
Service the prelters as soon as possible aer the prelter condion graph begins to rise. If the
lter condion graph gets all the way to “Replace” the machine will slow down. When display
reaches “Replace” a second me, the alarm will sound and the system will shut down to prevent
damage.
To service the lters close the thru-hull, open the housings, remove the old lters, clean out the
housing bowls, and reassemble the housings with new 20 and 5 micron lter elements. The 5
micron lter goes downstream from the 20 micron. Leave dry unl next startup.
Use only Spectra-approved lters or you may void your warranty. Occasionally, lightly lubricate
the O-rings with silicone grease.
Oil/Water Separator (Optional)
To install oil water separator capability, add a second lter housing UPSTREAM of the 20 and 5
micron housings. Service as you would per the instrucons above.
The Charcoal Fresh Water Flush Filter
Replace the charcoal filter element at least every 6 months. This filter protects the membrane by
removing chlorine from the flush water. Use only a Spectra-approved replacement.
51
Leaking Fittings
The system has eight high pressure ngs, two on each cylinder on the Clark Pump, two on
the pressure vessel end caps, and two 90-degree elbows on the back of the Clark Pump. As the
compression ng is ghtened, it compresses a ferrule onto the stainless tubing, xing the
ferrule permanently to the tube and holding the compression nut capve.
The body of the ng seals to the underlying component with an O-ring. On the Clark Pump
cylinders and the end caps this O-ring is compressed by ghtening the enre ng. The O-
rings on the 90-degree ngs on the back of the Clark Pump have capve nuts and washers,
which compress the O-rings without turning the enre ng.
If a tube ng leaks it can somemes be resealed by just ghtening. You must use two
wrenches, a 13/16-inch wrench to hold the base, and a 7/8-inch wrench to turn the compres-
sion nut. The 13/16-inch wrench will need to be thin so as not to interfere with the compres-
sion nut. If this doesn’t work, disassemble the ng, grease liberally with silicone grease (the
ferrule and the threads) and re-ghten rmly.
The base O-rings should be gently compressed to achieve a good seal, and may be damaged
by overghtening.

The Feed Pump and Clark Pump
The feed pump and the Clark Pump require no routine maintenance except inspection for
leaks. Tighten any hose clamps or fittings that show signs of leakage. The high pressure fittings
threaded into the Clark Pump have O-ring seals with a straight thread. These should never leak
and should never be over-tightened. If one of the tube nuts starts to leak, it can be un-
threaded, sealed with a bit of silicone grease or oil, and tightened with two wrenches very
tightly.
The Membrane
Membranes are susceptible to mineral scaling, biofouling and oxidation damage. The leading
cause of fouling is biological growth that forms when the system is left unused without flush-
ing or pickling. Fouling from mineral scaling can happen under certain seawater conditions, or
from rust. Oxidation damage can occur if the membrane comes into contact with any strong
oxidant, such as Ozone, Chlorine, etc. Monitor the product salinity and feed pressure for high-
er than normal readings, take environmental conditions into consideration.
Note that:
• Cold feed water or a higher salinity seawater source can cause high pressure.
• Low product flow is usually due to low voltage, a worn feed pump, or worn Clark Pump.
Due to the unique design of your Spectra system, low product water volume is typically not a
membrane problem, but frequently related to low voltage, a worn feed pump head, or a worn
Clark Pump. Always perform a flow test before cleaning your membrane.
Test to see if biological growth has occurred: Before running the system, remove the prel-
ters and examine their condion. If the lter housings are full of smelly, discolored water, the
system was not properly stored. Install clean prelters.
Next check the membrane. Detach the brine discharge hose, aach the brine service hose, and
lead it to a bucket. Open the pressure relief valve 1/2 turn, and manually run the system for 30
seconds (metal toggle switch on feed pump module). Examine the brine water: If it is discol-
ored and smells bad, perform an SC-2 cleaning with unchlorinated water before running the
system pressurized. If the brine is fairly clean, follow the New System Startup procedure on
page 32 and run normally. Check for performance. Clean the membranes only if performance
is reduced.
See the Cleaning Procedure for complete instructions.

Introducon to Spectra Chemicals
We use four types of chemicals: SC-1, SC-2, SC-3, and propylene glycol anfreeze. SC-1 and
propylene glycol are for system storage, while SC-2 and SC-3 are for membrane cleaning. Do
not use sodium-bisulfate, citric acid, or any other storage chemical not supplied by Spectra.
These chemicals, used to store other watermaker brands, will damage the Clark Pump, mem-
brane end plugs, manifolds, and other components. Using non-Spectra chemicals will void
the warranty.
Note: Never use any chemicals with the system pressurized! Always open the pressure relief
valve 1/2 turn. Always follow the instrucons for purging the chemicals as shown in the New
System Startup secon of your owner’s manual.
Storage
SC-1 prevents biological growth when your system is idle. It should not be used as a cleaning
chemical, nor will it protect your system from freezing. A jar of SC-1 is mixed with 1 to 2 gal-
lons of product or dechlorinated fresh water in a bucket and circulated through the system for
10 minutes. This treatment will protect the system for six months, aer which the SC-1 treat-
ment must be repeated. To use SC-1, follow the instrucons for Storage Procedure.
Spectra systems should be stored with propylene glycol if freezing is likely to occur. Propylene
glycol can be used instead of Spectra SC-1 storage chemical for storage in any climate, and
treatment is eecve for one year. Propylene glycol is a food-grade anfreeze used to winter-
ize RV’s, boats, and cabins. Do not use ethylene glycol automove anfreeze, which is toxic
and will damage the system.
The propylene glycol formulaons sold in marine and RV stores are usually diluted with water.
The water remaining in the watermaker before the storage procedure will further dilute the
anfreeze, reducing the microbial protecon and increasing the temperature at which the mix-
ture will freeze.
Anfreeze labeled “Minus Fiy” is a 25% soluon and will begin to form an icy slush at about
+15Degrees F (-10C) and will only provide burst protecon to about Zero F (-18C). Aer a fur-
ther 50% percent diluon by water remaining in the watermaker, “Minus Fiy” anfreeze will
only protect from bursng down to about +25F (-4C). Therefore if low temperature freezing
protecon is required a 60% or stronger anfreeze should be used. 60% soluons are labeled
“Minus 100” and will provide burst protecon to -15F (-27C) even aer a y percent diluon
with residual water. “Minus 200” formulaons are pure propylene glycol.
Maintenance - Cont.
54
Introducon to Spectra Chemicals - Cont.
Complete microbial protecon requires a 25% soluon of propylene glycol, so care must be
taken that the soluon remaining in the watermaker during long term storage is at least 25%,
even if freeze protecon is not required. For these reasons Spectra recommends that all pick-
ling be carried out with a 60% or greater concentraon.
See Winterizing with Propylene Glycol.
Propylene glycol can be dicult to ush from a membrane, especially aer extended storage
periods. This results in high salinity water (high PPM) and residual avor in the product water.
We recommend ushing the system WITH THE PRESSURE RELIEF VALVE OPEN for 4-6 hours
aer storage with propylene glycol—the longer the beer. If, aer extended ushing, you sll
experience low product water quality, cleaning with SC-2 usually removes all traces of propyl-
ene glycol and returns the salinity to the level it was before storage with propylene glycol. See
the Membrane Cleaning Procedure.
Cleaners
Avoid unnecessary cleaning, and avoid cleaning as a diagnosc tool.
SC-2 is an alkaline cleaner used to remove light oil, grime and biological growth. It is most
eecve if heated to 120 deg. F (49 deg. C). In most cases the water quality will increase in
PPM (salinity) aer an SC-2 cleaning. Aer a few hours it should recover to near the level it
produced before the cleaning.
SC-3 is an acid cleaner used to remove mineral and scale deposits. In most cases this is used
rst and if there is no improvement, go on to the SC-2 cleaning. SC-3 will in most cases lower

Storage Procedure
1. Close the intake seacock.
2. Push the Fresh Water Flush buon to fresh water ush the system. Perform a second fresh
water ush in the same way.
3. Remove the quick disconnect ng from the brine discharge outlet of the Clark Pump, per
photo below, and replace it with the quick disconnect brine discharge service hose. Lead the
brine service hose into the bucket.
4. Push the Auto Store buon and run the feed pump unl you have one gallon of fresh water
in the bucket from the brine discharge service hose, then press Stop.
5. Mix 1 container of SC-1 storage compound with the water in the bucket.
6. Remove the hose from the “to strainer” pigtail on the feed pump module and install the inlet
service hose from the service kit, per photos below. Lead this hose into the 5 gallon (20 liter)
bucket as well.
7. Make sure the pressure relief valve on the Clark Pump is
OPEN (un-pressurized) by turning 1/2 turn
counterclockwise
8. Turn on the feed pump by moving the manual control
switch on the control box to ‘SERVICE’. The soluon will be
drawn from the bucket with the service hose, and
returned to the bucket from the brine discharge service
hose. Circulate the storage chemical in the system for
approximately 20 minutes. Stop the feed pump by moving
the switch back to the ‘RUN AUTO’ posion.
Clean Up
Remove the brine discharge service hose from the Clark Pump, and replace the brine discharge
hose that leads to the thru-hull. You may now pump the bucket dry by moving the manual
control switch on the Control Box back to ‘SERVICE’. Stop the feed pump by moving the switch
back to RUN AUTO.
Remove the inlet service hose and reaach the hose from the sea strainer to the “To Strainer”
pigtail on the manifold at the Feed Pump Module. Drain and clean the strainer and any lters in
the system. Reassemble dry. Leave the pressure relief valve open, since the next me you run
the system you will need to purge the storage chemicals with the system unpressurized. Turn o
the power to the system.

Winterizing with Propylene Glycol
See descripon of propylene glycol formulaons, and purging from system, on page 53.
1. Close the intake seacock.
2. Push the Fresh Water Flush buon to fresh water ush the system. Perform a second fresh
water ush in the same way.
3. Remove the hose from the “To Strainer” pigtail, install the inlet service hose from the service
kit, and lead the hose to the boom of a bucket. Connect the brine service hose, and run it
into a second container.
4. Pour 1 gallon (4 liters) of propylene glycol of appropriate
concentraon (see page 46) into the bucket with the intake
service hose.
5. Make sure the pressure relief valve on the Clark Pump is
OPEN 1/2 turn (un-pressurized).
6. Run the feed pump by switching the manual switch on the
control box to ‘SERVICE’ unl about a gallon of water has
owed from the brine discharge service hose, or anfreeze
appears. Propylene glycol will look slightly dierent, and
feel more slippery, than water. Stop the pump by moving
the switch back to ‘RUN AUTO’. Add more propylene glycol to the intake bucket if necessary.
7. Lead the brine discharge service hose into the intake bucket of propylene glycol. Move the
switch back to ‘SERVICE’. The service hose will now draw propylene glycol soluon from the
bucket, and the brine discharge service hose will return it. Run the feed pump and circulate
the propylene glycol for 20 minutes.
8. Stop the feed pump by switching the toggle switch back to ‘RUN AUTO’. Drain the seawater
strainer, the hose leading to the boost pump module, and the hose between the boost pump
module and the feed pump module. Disconnect the product tubing from the membrane hous-
ing and blow residual water out of the tubing. Empty the charcoal lter housing and ush wa-
ter lines. Leave the pressure relief valve open, since the next me you run the system you will
need to purge the system unpressurized.
Your watermaker is now protected from freezing and biological growth and freezing for one year.

Membrane Cleaning Procedure
Spectra cleaning compound (SC-2 or SC-3) must be mixed with fresh water at a rao of 1 container of
compound to 3 gallons (12L) of unchlorinated water. A Bimini 300 system requires one container of com-
pound per cleaning.
1. Close the intake seacock.
2. Push the Fresh Water Flush buon to fresh water ush the system. Perform a second fresh
water ush in the same way.
3. Remove the quick disconnect ng from the brine discharge outlet of the Clark Pump, and re-
place it with the quick disconnect brine discharge service hose. Lead it into a 5 gallon (20 liter)
bucket. Push the Fresh Water Flush buon and run the feed pump unl one gallon of fresh wa-
ter runs into the bucket from the brine discharge service hose. Press Stop.
4. Remove the hose from the “To Strainer” pigtail and install
the inlet service hose from the service kit. Lead both hoses
into the bucket.
5. Make sure that the pressure relief valve on the Clark Pump
is open (un-pressurized).
6. Mix the cleaning chemical in the bucket. If possible, heat the
soluon to 120 F (49 C).
7. Move manual switch on the Feed Pump Module to SERVICE
SYSTEM. The intake service hose will draw soluon from the
bucket and the brine discharge service hose will return it.
Circulate the soluon through the system in this manner for 45 minutes. Stop the pump by
moving the toggle switch back to ‘RUN AUTO’.
8. If the soluon cannot be heated, allow the soluon to sit overnight before proceeding to the
next step.
9. Replace the brine discharge overboard hose and run the pump unl the bucket is empty by
moving the manual switch to ‘SERVICE’. Return the switch to ‘RUN AUTO’.
10. Follow the New System Startup procedures to ush the chemicals out of the system (DO NOT
CLOSE the pressure relief valve!)
11. The system may now be restarted, ushed, or stored.

In the event of a sensor failure resulng in a shut down due to a false alarm, the failed sensor can
be overridden (page 71 Spectra Connect Sengs). High Pressure, Service Prelter, System Stalled
(airlock), and Salinity Probe Failed can all be overridden and the system will sll run automacally
with all other funcons intact. Be absolutely certain that the alarm is false before overriding the
automac controls.
In the event of complete Connect control failure, the system may be operated manually as
follows:
• Switch on the feed pump by turning the toggle switch to RUN MAN. The automac safety con-
trols are disabled in manual mode. Shut the unit down if the Clark pump does not cycle, if air is
connuously present in the intake line, or if the feed pump is excessively noisy.
• Always discard the product water for the rst few minutes of operaon as the inial product
water may not be potable. Take a water sample by loosening the 1/4-inch product tube ng
at either the feed pump module or the membrane outlet. Check it with a handheld salinity me-
ter or taste it.
• The diversion valve is an electrically operated three-way valve, which is normally energized by
the Connect controls in order to send water to the tank. It will not open automacally in man-
ual mode, and must be opened using the mechanical override buon. The buon is located
on the side closest to the Clark pump cylinder. Push the manual override buon in and rotate
1/4 turn clockwise to open the valve.

Bimini 300 Flow Test
The ow test is the most useful diagnosc test for system performance, and should be done before
replacing or cleaning your membrane. Changes in producon or water quality are normally caused
by something other than the membrane, unless the system has been le unused for a long me.
Before the ow test, change all lters and clean the sea strainer. Carefully check for water or air
leaks, as air in the system will cause low producon and errac salinity. Look for air bubbles in the
product ow meter, feed water hoses, and brine overboard hose.
Run the system and watch the feed pressure very closely. If the feed pressure to the Clark Pump is
asymmetrical from one stroke to another, this impedes performance. A dierence of a few PSI is
acceptable, but anything over that is an issue. If the pump is asymmetrical, Clark Pump repairs
should be done before connuing with these tests.
If no asymmetry is noted, connue with this test.
You will need a graduated bucket, either a graduated pitcher or large measuring cup, and a stop-
watch. Log the voltage at the feed pump at the same time. Confirm at least 12.5 Volts at the Termi-
nal Block on 12-Volt DC systems; 25 volts on 24-Volt DC systems.
Take two measurements and compare them with the table on the following page. The first meas-
urement is the product flow alone. The second is the product flow combined with the brine dis-
charge flow to get the total flow or feed flow. You may take these measurements by two methods:
1. Time the product flow into a graduated pitcher, then divert both the product flow and brine dis-
charge together into a bucket, timing them to measure total flow.
OR
2. Divert the product flow into the pitcher while diverting the brine discharge into the bucket. Time
the flow of both at the same time. After calculating the product flow, pour the pitcher of product
into the bucket of brine to measure total flow.
The ratio of product flow to total flow gives us our recovery rate, as a percentage. If the percentage
is below the minimum it indicates an internal leak in the Clark Pump.
63
1. Product Flow: Product flow is expressed in Gallons Per Hour (GPH) or Liters Per Hour (LPH), by
this equation:
3600 ÷ time in seconds x quantity of water in gallons or liters=GPH or LPH
There are 3600 seconds in an hour.
Example: It took 3 minutes and 35 seconds to collect 1 gallon of product water.
3600 ÷ 215 x 1 = 16.74 GPH (3 minutes, 35 seconds is 215 seconds)
Example: It took 2 minutes and 25 seconds to collect 2.5 liters of product water.
3600 ÷ 145 x 2.5 = 62.07 LPH (2 minutes, 25 seconds is 145 seconds)
2. Total Flow or Feed Flow: Feed flow or total flow (brine + product) is expressed in Gallons Per
Minute (GPM) or Liters Per Minute (LPM) , by this equation:
60 ÷ time in seconds x quantity of water in gallons or liters = GPM or LPM
Example: It took 1 minute and thirty-seven seconds to collect 5 gallons of total flow.
60 ÷ 97 x 5 = 3.09 GPM (1 minute, 37 seconds is 97 seconds)
Example: It took 53 seconds to collect 12 liters of total flow.
60 ÷ 53 x 12 = 13.58 LPM
3. Recovery Rate: Product Flow ÷ Total Flow = Recovery Rate %
Example: 6.5 GPH product flow = .063 or 6.3%
1.7 GPM total flow x 60
(you must first multiply total flow by 60 to convert from GPM to GPH)
*pressure relief valve open ½ turn
In order to make good quality product water, you need the proper amount of feed water ow, as
in the table below. Compare the product ow to the total feed ow. Product ow should be 9.0%
of total ow for a Bimini 300. If product percentage is low, you may have an internal leak in the
Clark Pump.
For every
1
/
10
th
of a GPM feed water ow loss, we will lose about
1
/
2
gallon per hour of product
ow and the salinity will go up 100 PPM.
Low feed ow combined with low system pressures is most frequently caused by a worn pump
head.

Poor Product Water Quality
With any product water quality issue, you must ensure accurate calibraon if you are using a
salinity meter. For general quality evaluaon, your taste is always good enough.
Membranes are not an exact science and two idencal systems can have dierent product
quality. World health standards deem water of up to 1000 PPM of total dissolved solids ac-
ceptable for drinking. We consider any thing below 750 PPM acceptable but not ideal, and
anything below 500 PPM excellent. Factors that could aect water quality are addressed be-
low.
LOW SYSTEM FLOW OR PRESSURE will equate to lower product quality (higher PPM). Bi-
mini systems, which have a higher feed to output pressure rao (See nominal pres-
sures under Flow Test, page 45), as well as a higher feed ow/membrane area rao,
will produce water in the 150-300 PPM range.
DAMAGE TO THE MEMBRANE by chlorine contaminaon. Flushing the system with chlo-
rinated water will irreparably damage the membrane. Charcoal lters are used to ab-
sorb any chlorine which might be present in ush water. They must be of proper
specicaon to be suitable. There is no test for chlorine damage except the process
of eliminaon of other causes.
DIRTY OR SCALED membranes. A dirty (foreign material), scaled (mineral deposits), or
contaminated (bacterial growth) membrane can result in poor water quality and ab-
normal operang pressures. If operang pressures are above normal, then cleaning is
indicated. If the system pressures are within operang normal range, cleaning may
have lile result. Avoid cleaning as a diagnosc tool. Low water quality aer storage
with propylene glycol can usually be remedied by extended ushing or an SC-2 clean-
ing.
MECHANICAL LEAKAGE within the membrane pressure vessel. This is an unlikely but pos-
sible cause of poor water quality. A pinched or damaged O-ring within the pressure
vessel, a scratch on the product tube on the membrane, a scratch within one of the
end caps, or a seal fouled by contaminaon could allow sea water into the product
water.
If system total ow (product plus brine) is 2.4 GPM (9 liters) or above, the membrane is
clean, the product ows are consistent with the system ow and the water quality is sll not
acceptable, then replacement of the membrane is indicated.

Technical Bulletins
The following pages include Spectra’s most commonly-used technical bullens, covering tests,
adjustments, troubleshoong, and common points of confusion. Many more technical bulle-
ns are available on the Spectra website, www.spectrawatermakers.com.
ACCUMULATOR PRESSURE
Your Bimini 300 is supplied with a pressure accumulator tank (PL-ACC-TK) installed in the feed
water line between the feed pump and the Clark Pump.
The purpose of the feed line accumulator is to reduce the spikes in the feed pressure caused
by the cycling of the Clark Pump. If the accumulator is not properly charged it can lead to pres-
sure spikes and system shut down. The accumulator has a Schrader air valve, like a car re,
which allows the internal air bladder of the accumulator to be pre-charged. The accumulator
should be pumped up to about 60 psi (4.1 bar) for best results. Add air using a re pump or air
compressor. You can experiment with the exact pressure that will give the best pulsaon
dampening on your installaon.
Schrader valve
66
Prefilters
During normal operaon, the feed water is ltered in two stages. First it passes through a ne
mesh metal sea strainer, which protects the boost pump from foreign materials and sea crea-
tures. Aer passing through the boost pump, the feed water passes the lter housings con-
taining the 5 micron element, removing very ne parcles that could damage the feed pump
or Clark Pump and shorten membrane life. An addional carbon lter prevents the entrance of
chlorine during fresh water ushing (see next page).
Prelter maintenance schedules will vary widely depending on how and where the system is
used. If large amounts of feed water are run through the system in biologically ferle near-
shore waters the prelter will plug up, water producon and quality will drop, and the system
pressure will change dramacally. In blue water condions the prelter may only need to be
changed every week or two.
When operated for only an hour or two a day in inland or near-shore waters, the trapped
plankton will begin to decay in the lters long before the elements plug up. The decaying
plankton and bacteria will cause a roen egg smell in the product water. This decay will set in
overnight in tropical waters, or aer a week or two in higher latudes. If handled gently and
changed regularly before they get too smelly, lters can be cleaned several mes. (See
Maintenance, page 59.)
Our lter element part numbers are FT-FTC-XX, where the last digits indicate the micron
rang. FT-FTC-5 is for a 5 micron element, FT-FTC-20 is a 20 micron element. The oponal oil/
water separator is FT-FTC-OW.

67
Charcoal Filters
The charcoal lter element (FT-FTC-CC) removes chlorine from the fresh water ush water
supply, as the RO membrane can only handle small amounts of chlorine without permanent
damage.
The charcoal lter used for the fresh water ush system will not plug up unless you have very
dirty domesc water in your boat’s supply tank.
The charcoal lter we supply removes 99.7% of the chlorine. Beware when buying other char-
coal lters. If they don’t specify the percentage of chlorine removed, don’t use them. Cheap
ones may remove only 60% or 70%. Also, there are aermarket lters which are very close to,
but not exactly the right dimensions, and they will not seal in the housing. If you skimp on the
charcoal lter you risk damaging a $600.00 membrane on the rst ush. The other factor is
the ow rate that the lter can handle. Because the chlorine is adsorbed by the charcoal, it
must remain in contact with the charcoal for a sucient period of me for the all of the chlo-
rine molecules to be captured. The lters we use can handle 1.5 gallons (6 liters) per minute
ow, and are good for 3000 gallons (12,000 liters) at 1.5 GPM, or six months, whichever
comes rst. Regardless of the amount of water treated, the charcoal loses its eecveness
aer six months.

Always use cauon when changing any factory default sengs, as serious damage can
occur.
The Spectra Connect automacally monitors the operaon of the system to ensure a long and
trouble-free service life. If an operang parameter changes, the Connect can switch operang
modes, shut itself down, or automacally store itself in order to protect your watermaker.
It includes advanced calibraon sequences to make proper setup and maintenance of your
watermaker easier than ever.
The onboard me clock feature allows for temporary power interrupons without detrimental
eects on the system. In some cases your watermaker will connue to funcon in its last
known operang state.
The Spectra Connect has built in data logging, allowing for easy access to historical operang
data—which can indicate a wearing component or spares to be carried along before a failure
occurs.
Built in warnings for preventave maintenance automacally alert a user of pending
maintenance items, helping to keep your watermaker’s up-me to 100%! Advance warnings
are pre-programmed for Prelter Life, Clark Pump rebuilds, feed pump heads, membranes, Z-

Dealer Access Sengs
It is highly recommended that users consult with a factory trained technician before altering any sengs behind
the ‘Dealer Access Point’. Changing this sengs without understanding the full eect of each change can void
the warranty of your system, and cause irreparable damage.
If any sengs are inadvertently changed, they can be reverted back to the defaults by using the ‘Factory Reset’
feature.
Automac PRV: Enables an oponal Automac Pressure Relief Valve, aer it is installed. This seng should re-
main o unless you are certain that you have this feature installed on your system.
Power Sensor: Enables or disables an oponal power sensor, aer it is installed.
PH/ORP: Enables an oponal pH or ORP meter, aer it is installed.
Z-Ion: Enables or Disables the oponal Z-Ion system, aer it is installed. If the Z-Ion is enabled, you should also
adjust the Flush Interval to 30 days.
Tank Level Monitors
Tank Setup - Enable/disable tank sensors.
Enable Tank Switch High - Enable/disable tank switch high. If this is disabled Auto Fill and Fill Tank
run modes will not be available.
Enable Tank Switch Low - Enable/disable tank switch low. If this is disabled Auto Fill mode will not
be available. Both High and Low tank switches must be enabled for Auto Fill mode.
Enable Tank Level 1 - Enable/disable tank level sensor 1. If this is disabled there will be no tank level
reading and tank level gauge will read “!”.
Enable Tank Level 2 - Enable/disable tank level sensor 2..

Fault Handling
Faults are hazardous condions that might occur during running of your watermaker. The control board has the
ability to monitor these faults in real me and take necessary acons to prevent damaging your equipment.
HIGH PRESSURE FAULT
High pressure fault is triggered if
Outlet pressure (Feed/Membrane pressure) > Pressure Limit
If a high pressure fault is triggered, the system goes to low producon mode if it is running in high producon
mode, or stops the operaon if it is already running in low producon mode. Then the system will begin
the Auto Store mode.
Resoluons
Check for kinked or blocked hoses.
Conrm “#3 Sensor PSI High limit” and “#3 Sensor PSI Oset” opons on Outlet Sengs.
Clean membrane.
SYSTEM STALL FAULT
System stall fault is triggered if
There is no product ow for 1 minute connuously.
If system stall fault is triggered, machine will stop the current run cycle and will prompt to restart. If restarted
it will retry the previous running mode. If the stall condion persists even aer restart, the system will
begin the Auto Store mode.
Resoluons
Conrm product water at membrane endcap.
Check intake line for restricons, blockages or air leaks.
Close Pressure Relief Valve on Pump.
Conrm controller sengs correct.
SERVICE PREFILTER FAULT
The Service Prelter fault is triggered if
Inlet Pressure (boost pressure) < Low Vacuum Limit
If the Service Prelter fault triggers, the system goes to low producon mode if it is running in high produc-
on mode or stops the operaon if it is already running in low producon mode. Then the system will
begin the Auto Store mode.
Resoluons
Change prelters and the sea strainer screen.
Conrm adequate boost pressure in inlet pressure sengs.
Check for obstrucons in intake line.
Check sensor for proper operaon
POOR QUALITY FAULT
The High Salinity fault triggers if
The Salinity of the product water is above the threshold (measured salinity > Salinity 1 threshold) for
more than 8 minutes.
If the High Salinity fault is triggered, the machine will stop the current run cycle and will prompt to restart. If
restarted it will retry the previous running mode. If the High Salinity fault condion persists even aer
restart, the system will begin the Auto Store mode.
Resoluons
Check pump operaon - Clark Pump (pressure relief valve closed), Feed Pump (moving water).
Conrm product water quality.
Membrane damage - clean or replace.
Salinity probe out of calibraon.
Clean or replace salinity probe.
