Service
Port
The Cape Horn Xtreme is designed to be ecient, simple, and durable. Properly installed and
maintained it will supply years of reliable service. Prudent operaon is required with any marine
equipment. Always maintain enough reserve water to get safely into your next port.
The Spectra Intensier, known as the Clark Pump, was introduced in 1997 and has connually
improved since. It is built of modern non-corrosive composites and comes with a 40” (101.6 CM)
high rejecon membrane. The Clark Pump and membrane module are pre-mounted and plumbed
together as a single unit to save me and add reliability.

Thru-hull Locaon: The system must be connected to a dedicated 3/4” (1.91 cm)
to 1” (2.5 cm) 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
prevent air or contaminaon from entering the system. Do not install the intake close to, or
downstream of a head discharge, keel, stabilizer ns, or other underwater xtures.
Thru-hulls near the bow are suscepble to air intake in rough condions. Sharing a thru-hull can
cause ow restricons, intake of air bubbles or contaminants, 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 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 hose runs along the intake 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. Aer several hours of operaon, inspect all piping and hose clamps for
leaks.
Pipe Fing Instrucons: To seal plasc-to-plasc ngs, wrap 6 to 8 layers of Teon tape
around the threads. Hold the ng in your le hand and ghtly wrap the threads clockwise. For
smoother assembly, do not tape the rst (starng) threads.

Spectra High Pressure Fitting Instructions
The Cape Horn Xtreme 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
compression nut. The 13/16-inch wrench will need to be thin so as not to interfere with the
compression 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.

Cape Horn Extreme Wiring
DANGER:
The Cape Horn Xtreme has two feed pumps, which may be operated independently. For
maximum producon, both pumps are run at the same me. To save power, or to reduce
operang pressures, the system is run on a single pump. There are two main ways to wire the
system: Method 1 is the standard installaon, and preferable in most cases.
Method 1: Two Pairs of Wires from Distribuon Panel to Feed Pumps
Route two pairs of wires, as in the diagram below, from two fuses or breakers on the main
distribuon panel. With switches or breakers on the distribuon panel, this method allows you to
control the pumps remotely, which is helpful if the system is dicult to reach. You may also
control the system from the switches on the individual feed pumps during maintenance.
Refer to wire guides below. Wire length is the sum of the length of the posive and negave
wires. Example: In a 12-Volt system, 15 feet of duplex wire (two wires in a protecve cover) is
needed to connect the DC electrical panel to each feed pump module: 15 + 15 = 30 (the round-
trip length), so you would use #8 Gauge (16mm²) wire for each feed pump.
Connect wires using supplied terminal blocks, then seal connectors. Voltage drop will impair
performance of the system.

#8 Gauge (10mm²) up to 35 feet (10.6M)
Method 2: One Pair of Wires from Distribuon Panel to Cape Horn Xtreme
To streamline the wiring, one of the terminal blocks for the feed pump modules may be
eliminated, with the power leads for both feed pump modules led to a single terminal block.
Route a single pair of heavy wires from a fuse or breaker on the main DC electrical panel to the
terminal block. By this method the whole system may be powered on and o from the main
distribuon panel, but the individual feed pump module switches must be used to control each
pump.
The main supply wires will be protected by a fuse or breaker on the main distribuon panel, sized
to protect the supply wires, at least 20 Amp. Each individual feed pump must sll have
overcurrent protecon. The simplest way to do this is to add in-line fuse holders (installer
provided) to the posive wires between the terminal block and feed pumps. On 12-Volt systems
each pump should be protected with a 15 Amp fuse; on 24-Volt systems each pump should be
protected with a 7.5 Amp fuse.
Refer to wire guides below. Wire length is the sum of the length of the posive and negave
wires. Example: In a 12-Volt system, 7 feet of duplex wire (two wires in a protecve cover) is
needed to connect the DC electrical panel to the terminal block for the feed pump modules: 7 + 7
= 14 (the round-trip length), so you would use #10 Gauge (6mm²) wire.
Connect wires using supplied terminal block, then seal connectors. Voltage drop will impair
performance of the system.

Optional Z-Ion Protection 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
probes on your Z-Ion may be wearing down, and should be tested. The service light is just a

Every new system is shipped from the factory with nontoxic, food-grade propylene glycol. Propylene
glycol, Spectra Chemicals, or anything other than seawater or freshwater must be purged from the
system with the pressure relief valve open at least 1/2 turn. You can purge your system with seawater or
freshwater via the Spectra’s freshwater ush funcon. The system must be purged for a minimum of 60
minutes, or unl at least 40 gallons (151.42 liters) of water have moved through the system.
CAUTION: Damage will occur if the purge process is not properly followed and the membrane is
pressurized with chemicals in it. Check that no hoses are kinked or restricng ow.
Follow this procedure for starng a new system the rst me, and aer a system has been stored or
cleaned with chemicals.
1. First check that:
• All of your hose connecons are ght.
• The green warning tag and washer have been removed from under the pressure relief valve.
• The pressure relief valve is open at least 1/2 turn.
• The sampling valve is set to the sample posion.
• The brine line is able to freely discharge
For a purge with seawater
• Move to an area free of contaminated water, such as in a polluted harbor or canal.
• The inlet thru hull/seacock is open
For a purge using the freshwater ush
• The vessel’s pressurized water system is on
• The grey ush valve is open (horizontal)
2. Turn on Feed Pump A and check to make sure water is coming out of the brine discharge (thru-hull
above water).
3. Run the system without pressure for 60 minutes to purge the storage chemicals. The pressure gauge
should read less than 35 PSI. If purging with freshwater the sampling tube may discharge water.
4. Close the pressure relief valve. Turn on Pump B. The pressure should rise to 80-100 PSI. If pressure
does not rise Feed Pump A may need to be turned on and o in order to prime both pumps. Water
should begin to ow out of the sampling tube. If the ship is located in brackish or fresh water the
pressure will be lower.
Depending on storage and environmental condions the system may need to have addional purging
me. If the product water does not taste pure or sample below 500 ppm, purge or run the system for up
to 6 addional hours.

5. The system may be run with only one feed pump at a me or with both pumps simultaneously.
Water quality may improve slightly when running with both pumps, as product salinity decreases with
higher feed pressure.
In cold temperatures it may be necessary to run just one pump to reduce system pressure, as colder
water will increase operang pressure. Do not operate the system with feed pressures above 125 PSI
(8.6 Bar).
Over the course of regular use you will balance the service life of the pumps, producon quanty, and
energy consumpon when deciding when to run the system, and whether to run one or both pumps.
When running just one pump, it doesn’t maer whether you run feed pump A or B.

Testing with an Artificial Ocean
If it is not possible to test run the system with the boat in the water, tesng may be accomplished with an arcial
ocean. You will need 1.3 lbs. of non-iodized salt (rock salt, sea salt, or aquarium salt) to make 5 gallons (605 grams of
salt per 20 liters) of seawater that is about 33,000 PPM salinity (average seawater salinity). A good rule of thumb is 1/2
cup (.12 liters) of salt per gallon (4 liters) of water. Make sure the domesc water system is powered up and the boat’s
tank has at least 30 gallons (120 Liters) of water to purge the storage chemicals from the system. Conrm that the
charcoal lter is installed, and the domesc water line is connected.
1. Open the pressure relief valve on the Clark Pump half a turn. Remove the green tag and spacer!
2. Turn the yellow service valve on feed pump module A to OFF.
3. Open the grey ush valve on the charcoal lter housing on feed pump module A.
4. Start a feed pump (Flip metal toggle switch to ON, located on the top right corner of feed pump module A). Let
feed pump run for 60 minutes to purge the storage chemicals.
5. Stop the feed pump (metal toggle switch to OFF).
6. Connect the inlet service hose to the service port on feed pump module A, then connect the brine discharge
service hose to the quick disconnect on Clark Pump. Refer to the photos below. Route both hoses into a 5 gallon
(20 Liter) bucket. Turn product sample valve to the sample posion and route the product water into the bucket.
7. Open the grey ush valve and turn on the feed pump unl the container is lled with fresh water. Stop the pump
and close the grey ush valve.
8. Turn the yellow valve on feed pump module A to SERVICE.
9. Mix the salt to the proper proporon or use an aquarium hydrometer to adjust the specic gravity to 1.025.
10. Start the feed pump, allow to prime, then close the pressure relief valve on the Clark Pump. The system should
build pressure and make water by drawing the salt water from the bucket and returning it as brine and product.
11. Run the system under pressure and check for proper operaon and leaks.
Aer tesng the system stop the feed pump. Remove the inlet service hose and replace the brine discharge hose. Turn
yellow service valve to RUN. Perform a fresh water ush (next page). A fresh water ush will hold the system for 5 days.
If you don’t use the system in 5 days we recommend the storage procedures.

2. Turn the product sample valve to the SAMPLE posion.
3. Turn yellow service valve on feed pump module A to RUN.
4. Start the feed pump (metal toggle switch on feed pump module to ON) and check for
ow by inspecng the brine discharge or checking for pressure on your analogue
gauge. If there is no ow open the pressure relief valve on the Clark Pump and bleed
the air out of the feed pumps by running them one at a me.
5. Close the pressure relief valve. Aer 5 minutes check the product water with your
hand held salinity tester. When it is below 750 PPM, divert the product into your
tank by rotang the product sample valve handle 90 degrees.
6. Run the system unl you have lled your tank or made enough to meet your require-

Fresh Water Flush
1. Turn the yellow service valve to OFF. Open the grey ush valve on lter housing at top
of feed pump module A. If have the oponal Z-ION, ip the switch from Idle/Ready to
Run for the duraon of your ush cycle.
2. Flush for your calibrated opmal ush duraon (default is three minutes, see calibra-
on instrucons), alternang between pumps to circulate fresh water through the enre system.
Pressure will drop on the gauge, which indicates that the membrane is ooded with fresh water.
Stop the feed pumps.
3. Return the yellow service valve to RUN. Close the grey ush valve. If you have the oponal Z-ION,
turn it back to Idle/Ready. If you forget, the Z-ION will meout aer 15 minutes of runme to pro-
tect the probes.
You may now leave the system unaended for up to ve days (30 days with the Z-Ion) without further
aenon
Remember that you need to run the system almost a half an hour to make enough water for a fresh
water ush. You may noce that the system output is higher while charging your baeries as the ma-
chine is voltage sensive.

Opmizing the Fresh Water Flush Duraon
Three minutes is usually the right ush duraon to ensure that sea water is thoroughly ushed
out of the water maker 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 can be opmized for your boat: Your system may require more
than three minutes to adequately ush the system, or you might need less me, allowing you
to save more fresh water.
Opmize the me
Ideally the salinity of the brine discharge will be completely fresh just as the ush cycle is com-
pleted. Using the brine discharge service hose, direct the brine discharge into a bucket. While
the system is fresh water ushing, take repeated samples from the brine discharge and test it
with a handheld salinity meter. When the PPM drops below 1000 you can consider the system
to have been fresh water ushed, and note the elapsed me. This will be your opmum ush
duraon going forward.

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
environment. A fresh water flush every five days will greatly reduce biological growth but may
not stop it completely. You can also protect your watermaker with the optional Z-Brane or Z-Ion
systems: Both protect the membrane from bio-fouling without the use of storage chemicals.
DANGER/ATTENTION: For maintenance, always disconnect from power source rst.
The Seawater Strainer
The seawater strainer’s stainless steel element should be inspected, removed, and cleaned as
needed.
ATTENTION: 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 Prefilter
Service the prefilter on a regular basis. If the system is installed as shown on the plumbing
schematic, the pressure will fall on the remote gauge as the prefilter becomes dirty. Extremely
dirty filters will harm system performance and may cause the feed pump to cut out from high
pressure. Leaving dirty filters in the machine during long idle periods will cause biological
contamination. Please review prefilter bulletin to page 46. prior to running your system.
NOTE: Prelter elements must be changed frequently. The rate is solely dependent on the input
water. A 5-micron lter might last you a 4-6 weeks in clear open ocean seawater, or be ruined in
minutes in a dirty harbor. Spectra does not advise to aempt to clean dirty prelters. Prelters
are a consumable item and should be changed for new when in queson.
To service the lter close the thru-hull, open the prelter housing, remove the old lter, clean
out the housing bowl, and reassemble the housing with a new 5 micron lter element. Leave dry
unl next startup.
NOTE: Use only Spectra-approved lters or you may void your warranty. Occasionally, lightly
lubricate the O-rings with silicone grease.
34
Maintenance - Cont.
Oil Water Separator (Optional)
For oil/water separation, install the additional filter housing with its oil removal filter
upstream of the 5 micron filter. Service at the same time as the 5 micron filter.
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.
The Feed Pumps and Clark Pump
The feed pumps 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
Always perform a flow test before cleaning your membrane. Cleaning with chemicals shortens
the lifespan of membranes, so only clean if you are certain it is warranted. The leading cause
of fouling is biological growth that forms when the system is left unused without flushing or
pickling. Fouling from mineral scaling can happen during operation under certain seawater
conditions, and from rust. Monitor the product salinity and feed pressure for higher than
normal readings, and take environmental conditions into consideration:
• Cold feed water or clogged filters can cause high pressure.
• Low product flow is usually due to low voltage, a worn feed pump, or a worn Clark Pump.
Test to see if biological growth has occurred: Before running the system, remove the prelter
and examine its condion. If the lter housing is full of smelly, discolored water, the system
was not properly stored. Install a clean prelter.
Next, check the membrane. Aach the brine discharge service hose and lead it into a bucket.
Open the pressure relief valve half a turn, and manually run the system for 30 seconds (metal
toggle switch on feed pump module). Examine the brine water: If it is discolored 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 and run
normally. Check for performance. Clean the membranes only if performance is reduced.
NOTE: See the Cleaning Procedure (pg. 39) for complete instructions.

Introduction 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.
CAUTION: Do not use metasodium-bisulfate, citric acid, or any other storage chemical not
supplied by Spectra. These chemicals, used to store other watermaker brands, are very acidic
and will damage the Clark Pump and void the warranty.
CAUTION: 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.
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 3
gallons 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
treatment 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
winterize 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
mixture will freeze.
Anfreeze labeled “Minus Fiy” is a 25% soluon and will begin to form an icy slush at about
15°F (-10°C) and will only provide burst protecon to about 0°F (-18°C). Aer a further 50%
percent diluon by water remaining in the watermaker, “Minus Fiy” anfreeze will only
protect from bursng down to about 25°F (-4°C). 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 -15°F (-27°C) even aer a y percent
diluon with residual water. “Minus 200” formulaons are pure propylene glycol.
36
Introduction to Spectra Chemicals - Cont.
Complete microbial preservave 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 pickling be carried out with a 60% or greater concentraon.
NOTE: See Winterizing with Propylene Glycol on page 38.
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
propylene glycol and returns the salinity to the level it was before storage with propylene
glycol. See the Cleaning Procedure on page 39.
Cleaners
Cleaning can be detrimental to the membrane and shorten its life. Avoid unnecessary
cleaning, and avoid cleaning as a diagnosc tool.
SC-2 s an alkaline cleaner used to remove light oil, grime, and biological growth. It is most
eecve if heated to 120°F (49°C), which is dicult on a boat. 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. SC-3 will in most cases lower the
product PPM and overall pressures. Scaling is a slow process that may take several months or
years. SC-3 is less harmful to the membrane and will almost always improve the performance
of an older membrane.
For cleaning with either SC-2 or SC-3, see the Membrane Cleaning Procedure on page 39.
37
Storage Procedure
NOTE: When storing with SC-1 you only need to use one feed pump to circulate the storage soluon
through the watermaker, but you should briey alternate pumps to ensure that the SC-1 soluon is
circulated throughout the system. The watermaker will contain about 2 gallons (8 liters) of water, so
starng with one gallon (4 liters) in the bucket there will be about 3 gallons (12 liters) of soluon.
CAUTION: Make sure the pressure relief valve on the Clark pump is Open (unpressurized), 1/2 turn
counterclockwise OR THE MEMBRANE WILL BE DAMAGED.
1. Perform a fresh water ush. Turn o the feed pump and close the grey fresh water ush valve.
Leave the yellow service valve OFF.
2. Disconnect the brine discharge hose from the Clark Pump, and replace with the brine service hose
from your service kit. Lead the brine service hose into a bucket.
3. Do another fresh water ush and run the feed pump unl you have one gallon (4 liters) of fresh
water in the bucket. Turn o the feed pump and close the grey fresh water ush valve.
4. Mix one container of SC-1 storage compound with the water in the bucket. It will not dissolve
completely, which is normal, and any parcles will be caught by the lter.
5. Connect the intake service hose to the service port on feed pump module A and lead the hose into
the soluon in the bucket. Turn the yellow service valve to SERVICE. The system will now draw the
soluon from the bucket and return it via the brine discharge service hose.
6. Turn on a feed pump and circulate the storage chemical through the system for approximately 10
minutes, alternang feed pumps. Turn o the feed pumps.
Clean Up:
1. Remove the brine discharge service hose, and replace the brine discharge hose leading to the thru-
hull.
2. Turn the yellow service valve back to RUN, and remove the intake service hose.
3. Close the seacock, drain and clean the sea strainer and prelter. Reassemble dry with a new lter.
Your system is now protected for the next six months.

Winterizing with Propylene Glycol
CAUTION: Use only potable water anfreeze (Propylene Glycol).
Do not use automove anfreeze (Ethylene Glycol).
Propylene Glycol is an eecve biocide and anfreeze. Purchase the strongest anfreeze available. See
Introducon to Spectra Chemicals on page 35 for addional details.
1. Fresh water ush the watermaker. Turn o the feed pumps. Close the grey ush valve (located on feed
pump module A).
2. Connect the inlet service hose to the service intake on feed pump module A, and lead it into a bucket.
Turn the yellow service valve to the SERVICE posion.
3. Connect the brine discharge service hose to the quick disconnect on the side of the Clark Pump and
lead it into a second container.
4. Pour 1 gallon (4L) of propylene glycol of appropriate concentraon into the bucket with the intake
service hose. (See Introducon to Spectra Chemicals for discussion of propylene glycol concentraon on
page 36)
5. CAUTION: Make sure that the pressure relief valve on the Clark Pump is OPEN a 1/2 turn, OR THE
MEMBRANE WILL BE DAMAGED.
6. Turn on one of the feed pumps unl about a gallon of water has owed from the brine discharge, or
propylene glycol appears. Propylene glycol will look slightly dierent, and feel more slippery, than
water. Stop the pump. Add more anfreeze to the intake bucket if necessary.
7. Lead the brine discharge service hose into the bucket of propylene glycol. The system will now draw
propylene glycol from the bucket and return it via the brine discharge hose.
8. Circulate the anfreeze in this manner for about 10 minutes, alternang feed pumps.
9. Stop the feed pumps. Reconnect the brine discharge hose that leads to thru-hull. Run the feed pump
unl the bucket is empty.
10. Close the seawater intake. Turn yellow service valve to OFF. Drain the seawater strainer and the hose
leading to the feed pump modules. Disconnect the product tubing from the membrane housing and
blow residual water out of the tubing. Empty the charcoal lter housing and ush water lines.
Your watermaker is now protected from biological growth and freezing for one year.

NOTE: Procedures are the same for the SC-2 and SC-3 cleaners
A Spectra cleaning compound (SC-2 or SC-3) must be mixed with fresh water at a ratio of 1 container of
compound to 3 gallons (12L) of unchlorinated fresh water. An average of two gallons (8 liters) of water is
already present inside a Cape Horn Xtreme system, and this water must figured into the mixture. Warm
water is ideal for cleaning membranes: Use a large stainless steel pot to heat the solution to 120°F(49°C).
You might have to periodically stop and reheat the solution.
1. Perform a fresh water flush. Stop the feed pumps and close the grey flush valve.
2. Connect the inlet service hose to the service intake on the feed pump module A. Connect the brine
discharge service hose to the quick disconnect on the Clark Pump. Lead the hoses into a bucket. Open
the grey flush valve and run feed pump A until you have 1 gallon (4 liters) of water in the bucket.
3. Turn off the feed pump and close the grey fresh water flush valve.
4. Turn the yellow service valve on feed pump module A to SERVICE.
5. CAUTION: Make sure the pressure relief valve on the Clark Pump is OPEN 1/2 a turn (system is un-
pressurized) OR THE MEMBRANE WILL BE DAMAGED.
6. Mix the cleaning chemical with the water in the bucket.
7. Start feed pump A and circulate the chemical through the system for 45 minutes, if the solution is
warm. Let the solution sit in the unit overnight if the cleaning solution is cold.
8. Stop the pump, replace the brine discharge hose, and run the pump until the bucket is empty. Stop the
feed pump and turn the yellow service valve to RUN. Follow the instructions for a New System Startup.
CAUTION: KEEP PRESSURE RELIEF VALVE OPEN to flush out the cleaning chemicals.

Flow Test for Dual ShurFlo Pumps (Cape Horn Extreme)
NOTE: 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 the prelter 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 pressures very closely. If the feed pressure to the Clark Pump is
asymmetrical from one stroke to another, this could be part of the problem. 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
stopwatch. Before the flow test, change all filters and clean the sea strainer. Carefully check for
water or air leaks, as air in the system will cause low production and erratic salinity. Observe the
feed pressure and ensure that the Clark Pump cycles symmetrically. Log the voltage at the feed
pumps at the same time. Confirm at least 12.5 Volts at the feed pump on 12-Volt DC systems;
25 volts on 24-Volt DC systems.
Take two measurements and compare them with the table in the New System Startup section.
The first measurement is the product flow alone. The second is the product flow combined with
the brine discharge 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
discharge together into a bucket 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. 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 the recovery rate, expressed as a percentage. If
the percentage is below the minimum it indicates an internal leak in the Clark Pump.
41
On the Cape Horn Xtreme, you should perform the tests using each pump alone, then using
both pumps. Compare the results to the table in the New System Startup section.
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)
In order to make good water, you need the proper amount of feed water ow. Each pump
alone should produce 1.5 gallons per minute (5.7 LPM) of brine discharge PLUS product water.
Running on both pumps the ow should be 2.7 GPM (10 LPM).
Compare the product ow to the total feed ow. Product ow should be between 8% and 9%
of total ow for a Cape Horn Xtreme. If product percentage is low, you may have an internal
leak in the Clark Pump and it probably needs to be rebuilt.
For every

th
of a GPM feed water ow loss, we will lose about

DWYER FLOW METER SERVICE
The mechanical ow meter, PL-FMT-10 (10 GPH range) or PL-FMT-20 (20 GPH range) can be
opened for cleaning if it becomes dicult to read or if the lile ball gets stuck.
The ow meter will come completely apart for cleaning. First remove the meter from the pan-
el. Remove the four small screws that hold the stainless steel bracket in place. Carefully wedge
out the steel bracket. Above where the bracket was removed, there is a clear plasc slide-out.
Use a at bladed screwdriver to pull it out carefully. Once it is out, insert your athead into the
space it was removed from and gently nudge upwards to remove the top piece. Invert the ow
meter and catch the ball as it falls out. You can use tooth paste or plasc window polish to
polish the inside using a small bole brush, or simply a q-p. Clean the ball and give it a few
coats of wax. If the O-rings are damaged or the unit has been leaking, install new O-rings using
a lile silicone grease to ease assembly. These are standard O-rings and should be available at

ACCUMULATOR PRESSURE
Your Spectra watermaker is supplied with a pressure accumulator tank (PL-ACC-TK), which
should be installed in the feed water line between the prelters 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
problems with the Shuro pump pressure cutout switches.
NOTE: 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 65 psi (4.5 bar) for best results. Add air using a re pump or air compressor. You can ex-
periment with the exact pressure that will give the best pulsaon dampening on your installa-
on.

ATTENTION:
A Cape Horn Xtreme system uses two dierent lters to prevent damaging foreign materials from en-
tering the system. A single 5 micron lter cleans the feed water of abrasive materials while the system
is in operaon; an addional carbon lter prevents the entrance of chlorine during fresh water ush-
ing.
During normal operaon, the feed water is ltered in two stages. First it passes through a ne mesh
metal sea strainer, which protects the feed pump from foreign materials and sea creatures. Aer pass-
ing through the feed pump, the feed water passes the lter housing containing 5 micron element, re-
moving very ne parcles that could damage the Clark Pump and shorten membrane life.
Replacement schedules will vary widely depending on how and where the system is used. If large
amounts of feed water are run through the system over a relavely short period of me in biologically
ferle near-shore waters, the prelter will plug up, water producon and quality will drop, and the sys-
tem pressure will change dramacally. If the pressure gauge was installed aer the prelters, as pic-
tured on the plumbing schemac, the pressure will decrease as the lter becomes more clogged.
It is important to remember that your Spectra Watermaker is designed to process clean, open-
ocean seawater. Any departure from that standard for your seawater intake runs the risk of caus-
ing excessive wear or damage to internal pump parts and/or the vulnerable reverse osmosis
membrane. Addional preltraon consideraons and/or extremely frequent prelter replace-
ments may be required in any deviaon from open-ocean seawater. Your local service provider or
installer may have specic recommendaons based on their experience with water condions
unique to your region.
Observe the seawater around your vessel. Is it clean enough to use for your seawater intake? There
are several things to avoid feeding to your watermaker:
• petroleum products, such as oil, fuel, thinners, paints, paint removers, etc.
• chlorine-treated water; e.g., most “dock” water
• silty water — water contaminated by ne, hard, suspended parculates
• putrid water, “red des”, or any seawater that smells or looks contaminated
• harbor/marina water that you cannot see through or that shows visible signs of
contaminate (neighboring boats docked nearby may be discharging contaminaon!
Sewage, chemicals, etc.)
Judging the quality of seawater input always involves a certain calculated risk. We know of water-
maker systems that have been destroyed far oshore by intaking fresh whale excrement or oil con-
taminants from natural seepages. The chance of such things happening is normally small but should
be considered. On the other hand, regularly running a watermaker in an enclosed marina or har-
bor runs a much higher risk of harmful contaminaon. If you need to test a new installaon while
in a marina or harbor, monitor the water quality around your vessel carefully while tesng. Oen
mes you should be able to run the watermaker safely for enough me to briey check out the sys-
tem if you are mindful of external feed condions. If this is not possible, an arcial ocean is a use-
ful alternave (see Page 26 for arcial ocean tesng/instrucons). Don’t sail away without tesng
a new installaon or repair!

CHARCOAL FILTERS
ATTENTION:
The charcoal lter element (FT-FTC-CC) removes chlorine from the fresh water ush water
supply. The RO membrane can only handle small amounts of chlorine without permanent
damage. If the fresh water ush water contains chlorine, the membrane will be exposed to it
for days and will produce high salinity water.
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. About six months aer installaon the char-
coal lter element will lose its eecveness and must be replaced. This is purely a funcon of
me.
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 same dimensions, and will not seal properly in the housing. If you skimp
on the charcoal lter you risk damaging a $600.00 membrane on the rst ush. The other fac-
tor is the ow rate that the lter can handle. Because the chlorine is adsorbed by the char-
coal, it must remain in contact with the charcoal for a sucient period of me for the all of
the chlorine 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, whichev-
er comes rst. Regardless of the ow, the charcoal loses its eecveness aer six months.
Charcoal lter, Spectra part number FT-FTC-CC
PREFILTERS CONT.
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 lter long before it plugs 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. In crystal clear blue water condi-
ons, the lters may need to be cleaned much less frequently.
If handled gently and changed regularly before they get too smelly, lters can be cleaned and
reused several mes.
Our lter element part number is FT-FTC-XX. The last digits indicate the micron rang, e.g. FT
-FTC-5 is for a 5 micron element:

SHURFLO PUMP WON’T RUN
If the pump has power to it but the pump won’t run, rst check the pressure switch. The
pressure switch (EL-FP-PS) is located on the wet end of the pump and has two red wires
plugged into it.
DANGER: Jump the two red wires together and see if the pump runs. You can safely run the
system with the pressure switch jumped, just keep an eye on the pressure gauge and don’t let
system pressure exceed 110 PSI. Replace the switch when a spare is available. The pressure
switch should never open unless there is a problem with the system or it is incorrectly
adjusted. Check the accumulator pressure, the operang feed pressure, and the switch cut-out
seng.
If the pump will not run with the pressure switch jumped then it is most likely a problem with
the brushes or overheat protecon switch inside the motor. The motor will come completely
apart by removing the two screws on the end of the motor. Remove the rear cover and paper
insulator. Pull out the plasc brush holder. The thermal switch is located on one of the brush
leads. With an ohmmeter, check for connuity through the switch. If it is open, you can make
temporary repairs by wiring around it, being careful that your new wiring doesn’t chafe on the
moving parts, nor resist the springs that push the brushes on to the commutator. The overheat
switch is unlikely to fail unless the motor has overheated and shut down. Consider relocang
the pump or improving venlaon if the overheat protecon has failed.
If any corrosion is apparent the brushes may be scking. Once apart clean all the carbon dust
from all the parts. Clean the commutator with light sandpaper. Make sure to clean the small
grooves on the commutator with a small sharp tool to remove the carbon in between the
segments. Adjust the springs on the brush holders so the brushes slide smoothly in and out. If
the bearings are rough and binding, remove the rubber dust cover and clean the best you can,
grease them, and work them free by hand. Don't service the bearing unless absolutely
necessary. Reassemble in reverse order. You can hold the carbon brushes back with papers
clips inserted through the slots in the brush holder so they don't hang up on the bearing during
assembly. Make sure the corrugated bearing shim doesn't push out, if it does, push it back into
place.

ADJUST SHURFLO PRESSURE SWITCH
Shuro feed pumps are equipped with a high pressure cutout switch (EL-FP-PS). This is the
small black unit on the end of the wet end of the pump head (PL-PMP-SFPH) where the two
red wires connect. If the pressure switch is not properly adjusted the pump may cut out each
me the Clark pump cycles and the feed pressure spikes. When this happens the producon
will drop and salinity will increase. The points in the switch will fail quickly if set too low
because of the constant arcing each me the Clark Pump shis.
On the very center of the switch is a small 5/64” Allen screw. While running the system close
the brine discharge seacock or kink the discharge hose, to block the ow. Watch the pressure
gauge and adjust the pressure switch to shut o at 125 psi. Turn the Allen screw clockwise to
increase the cut o set point.

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
acceptable for drinking consumpon. 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 below.
LOW SYSTEM FLOW OR PRESSURE will equate to lower product quality (higher PPM).
Cape Horn Xtreme systems will produce slightly beer quality water running two
pumps, as this will create higher pressure and lower salinity. Worn feed pump heads
or ow restricons will cause lower feed pressure and higher salinity.
DAMAGE TO THE MEMBRANE by chlorine contaminaon. Flushing the system with
chlorinated water will irreparably damage the membrane. Charcoal lters are used to
absorb 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.
DANGER:
DIRTY OR SCALED membranes. A dirty (foreign material), scaled (mineral deposits), or
contaminated (bacterial growth) membrane can result in poor water quality and
abnormal 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
cleaning.
MECHANICAL LEAKAGE within the membrane pressure vessel. This is an unlikely but
possible 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.
NOTE: If system ow (product plus brine) is 2.7 GPM or above (1.6 GPM running one feed
pump), 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.
