Product sampling valve. Mount using the sup­plied plastic straps as shown.
Note: the handle is pointing in the direction of the flow.
Use accumulator port to connect the pressure gauge. Use the supplied 1/4” black nylon tub­ing. If other tubing is used it must be pressure rated to 150 PSI (10 BAR)
Route the product water from the valve into the top of the tank. Install a tee in the water fill or tap a pipe thread into an inspection port.
Product to tank. DO NOT! feed the product into a vent
line, manifold or the bottom of the tank. Make sure that there is no restriction in this piping. Pressure in the product tubing must never exceed 5psi (.3bar) at any time, (running or stopped) or the membrane will be permanently dam­aged.
Pressure Gauge
Plastic fittings should have 3-4 wraps of Teflon tape and will thread almost all the way in. Leave the first pipe thread uncoated. Avoid getting dirt or debris in the system during assembly. Secure piping away from moving objects and protect from chafe. Exercise care not to cross thread the fittings. See the tube assembly instructions next page.

Membrane Pressure Vessel Relocation
Use ONLY Dayco Imperial Nylo-Seal 88-NSR-1/2 tubing for high pressure connections. Pay attention to the direction and flow path of the tubing before disassembly. Make sure that you reinstall the tubing in the same manner. Rotate the 90 degree high pressure tube fittings on the Clark Pump for ideal tube runs. The high pressure fittings are typically pre­installed at the factory. These fittings seal with an O-ring and require no Teflon tape or pipe dope. Loosen the backing nut, rotate the fitting, and reseat the backing nut.
Follow the high pressure tube connection instructions on the next page. Connect the tubes to one of the components, secure the tube runs, and then trim and connect to the other component. A 90 degree bend in a tube is better than a 90 degree fitting. A tube, when mounted, should have at least one gentle bend to allow for expansion. Do not connect a
tube straight between hard mounted fittings.
When connecting the tubes to their components, be sure to hold the fitting body with a wrench during the final tightening. Of special note are the stainless steel tube fittings on the membrane housing which seal on an O-ring and should be seated all the way in. Hold the fitting with a wrench while installing the tube.
The fittings on the Clark Pump have an O-ring seal and can be reoriented by backing out the O-ring stop nut. Rotate the fitting to align with the tube and tighten the nut just past hand tight. DO NOT over tighten!

Spectra High Pressure Tube Fitting Assembly
Use ONLY Dayco Imperial Nylo-Seal 88-NSR-1/2 tubing for high pressure connections.
Carefully fit and measure the tubing before cutting with a sharp razor knife or hose cutter and remove any burrs. Minimum tubing bend radius is 6”. Route tubing away from excessive heat sources and secure from vibration and chafe. Have at least one shallow bend in the tube assembly after it is installed.
Refer to figure 1. If a fitting has been dissembled, reassemble as illustrated. The notch on the ferrule must engage the inside of the nut properly for the nut to seat down fully. Once the tube is inserted the ferrule and nut will naturally align.
Refer to figure 2. Insert tube fully into the fitting; it should go in 0.9”. Tighten the nut finger tight while moving the tube around to prevent binding. One thread should be showing under the nut. Secure the tube so it won’t back out when tightening.
Refer to figure 3. Use 13/16” wrench to hold a straight body fitting or a 3/4” wrench for a 90º body, and a 7/8” wrench for the nut. Hold the body, recheck the tube insertion, then tighten the nut 1-1/4 turns. Use the index mark on the nut as a guide. The threads should be completely covered by the nut.
Make sure these fittings are tight on initial assembly or they will fail!

Ventura Deluxe New System Start-Up and Testing
Avoid running the Ventura system if the vessel is in contaminated water, such as in a pol­luted harbor or canal. The system should be fully run tested before leaving on your cruise. If the location or weather prevents proper testing refer to the section “Dry Testing.”
Warning! Damage may occur if the purge sequence is bypassed and the membrane is pressurized with storage chemical in it.
1. First check that:
Thru-hull inlet valve is open and the brine discharge valve is open.
All of your hose connections are tight.
The “WARNING” tag and spacer from under the pressure relief valve has been
removed.
The pressure relief valve is open 1/2 turn.
The sampling valve is set to the sample position.
Open 1/2 Turn to Purge Chemicals! Remove Tag and Washer!
2. Turn on the feed water pump. Check that it is primed by inspecting the brine discharge. About 1.5 gpm (6 lpm) of water should be going overboard with a pulsation every few sec­onds.
3. Run the system without pressure for 20 minutes to purge the storage chemicals. The system should have an open flow pressure on the gauge of about 20 PSI (1.2 bar).
4. Close the pressure relief valve. The pressure should rise to 60-80 PSI (4.2-5.7 bar). After several minutes, water should begin to flow out of the sampling tube. If the vessel is located in brackish or fresh water the pressure will be lower.
5. Allow the system to run for 5-10 minutes and then test the product with your hand held sa­linity tester. When the product is below 750 PPM it is considered potable and may be diverted to the tank.

Ventura Deluxe Dry Testing With Artificial Ocean
If it is not possible to test run the system with the boat in the water, testing may be accomplished with
an artificial ocean. Purchase enough aquarium salt to make 5 gallons (20 liters) of salt water.
Make sure that the domestic water system is powered up and that there is at least 30 gallons (120 Li­ters) of water in the tank. Confirm that the charcoal filter is installed in the fresh water flush module and that the domestic water line had been installed and all valves are open.
1. Open Pressure Relief Valve on the Clark Pump. Remove the green tag and spacer!
2. Close the yellow service valve on the inlet module. This will be the center location.
3. Open the grey fresh water flush valve.
4. Start the feed pump and let it run 20 minutes to purge the storage chemical overboard.
5. Stop the feed pump
6. Hook up your inlet and brine discharge service hoses per the photo and route them into the 5 gal­lon (20 Liter) container. Turn your product sample valve to the sample position. Route the prod­uct output into the bucket.
7. Restart the feed pump and fill the bucket with fresh water from the brine discharge. Stop the pump and close the fresh water flush valve.
8. Rotate the yellow service valve to the service position.
9. Mix the salt to the proper proportion or use an aquarium hydrometer to adjust the salinity level.
10. Start the feed pump, allow to prime and then close the pressure relief valve. The system should
build pressure and after several minutes start making water.
11. Run the system under pressure and check for proper operation and leaks.
After testing the system stop the feed pump and replace the brine discharge hose. Restart and drain the bucket. You can now store the system by using the above procedure for adding fresh water to the bucket and using the storage procedure. If the system is to continue to be commissioned performing, a fresh water flush will hold the system for 4-5 days.

Ventura Deluxe Operation
Normal operation
If the system has been pickled or stored or contains cleaning compounds, use the “New System Startup” procedure.
1. Check to see that the inlet seacock is open.
2. Turn the product valve to the “Sample” position.
3. Start the feed pump and check for flow by inspecting the brine discharge or checking for pressure on your analog gauge. If there is no flow open the pressure relief valve on the Clark Pump and bleed the air out of the feed pump.
4. Check the product water with your hand held salinity tester. When it is below 750 ppm, you may divert it into your tank.
5. Run the system until you have filled your tank or have made enough to meet your re­quirements for several days.
6. Turn on the fresh water flush valve and close the service valve.
7. Flush for 2 1/2 minutes or until the pressure drops on the gauge indicating that the mem­brane is flooded with fresh water. Stop the feed pump.
8. Return the service valve and the flush valve to their run positions.
You may now leave the system unattended for up to five days without further attention We recommend operating the system for longer periods and effecting a fresh water flush rather than running the machine every day and not flushing the system. Remember that you need to run the system almost a half an hour to make the flushing water. You may notice that the system output is higher while charging your batteries as the machine is voltage sensitive.

Long Term Storage Procedures
Watermakers are best run continuously. When not in use, biological growth in the mem­brane is the leading cause of membrane fouling. A warm environment will cause more growth than a cold environment. The fresh water flush system will greatly reduce biologi­cal growth but may not stop it completely in certain conditions. If an optional “Zeta Guard” or Z-Brane water treatment system is installed in the system, then three to five day flushing intervals will maintain the system as long as fresh water is provided and the charcoal filter maintained.
System Storage or “Pickling”
If the system is to be left unused for more than five days, perform the following storage pro­cedure. The procedure introduces a chemical compound into the system that prevents bio­logical growth. This procedure requires de-chlorinated water which can be made with the charcoal filter. Charcoal filters last a maximum of 6 months once wetted.
Spectra SC-1 a special storage compound used by the US Navy. It is formulated to be compatible with the modern engineering plastics and composites in the Spectra pumps. Do not use any substitute except propylene glycol. If you wish to use glycol for storage, follow the winterizing instructions. SC-1 Storage Compound has to be mixed at a ratio of 1 container to 3 gallons (12L) of fresh water to have the proper solution for short term storage (under two months use 1/2 of a container)
Caution! Avoid contact with skin, eyes, or lungs with the storage chemical.
17
Page 18
Ventura Deluxe Storage Procedure
1. Perform a fresh water flush as described in the normal operation section. Shut down the feed pump but leave the valves in the flush position.
2. Remove the quick disconnect fitting from the brine discharge outlet of the Clark Pump and replace with a quick disconnect service hose from your service kit. Lead the hose to a 5 gal­lon bucket or container.
3. Start and run the feed pump until you have one gallon of fresh water in the bucket.
4. Mix 1 container of SC-1 storage compound with the water in the bucket.
5. Connect the service hose, using the garden hose barb fitting from your service kit, to the service port of the fresh water flush module. Lead the hose into the bucket. Turn the service valve on the fresh water flush module 180°, so the intake is now coming from the bucket.
6. Make sure the pressure relief valve on the
Clark Pump is OPEN (unpressurized)
by turning 1/2 turn counterclockwise
7. Turn on the feed pump. Circulate the storage chemical in the system for approximately 10 minutes. Turn off the feed pump when fin­ished.
Clean Up
Remove the quick disconnect from the Clark Pump brine discharge, and replace the original hose that leads to the thru-hull. You may at this point, if you choose to, pump the bucket dry by using the feed pump switch. Stop when the bucket is empty.
Turn the service valve 180° back to its original position, and remove the service hose. Close the seacock and drain and clean the strainer and any filters in the system. Reassemble dry.
18
Page 19
Pickling and Winterizing with Antifreeze
The watermaker can be stored for periods up to one year in any climate using this procedure.
1. Close the yellow service valve, open the Grey flush valve, and run the feed pump 4 minutes
to effect a complete fresh water flush. Shut the pump and flush valve off.
2. Connect the inlet service hose and put it in the service container or bucket.
3. Turn the service valve to the service position.
4. Pour 2 gallon (8L) of propylene glycol in the bucket.
5. Make sure that the pressure relief valve is OPEN (un-pressurized).
6. Turn on the feed pump until antifreeze begins to show at the brine overboard fitting, then
stop the pump. Add more antifreeze if necessary.
7. Connect the brine discharge service hose and place it in the bucket.
8. Circulate the antifreeze for about five minutes.
9. Stop the pump. Reconnect the brine discharge hose. Restart the pump until the bucket is
empty.
10. Close the seawater intake and the service valve. Drain the strainer and the hose leading to
the inlet module. Disconnect the product tubing and blow any residual water out of the tub­ing with compressed air. Empty the charcoal filter housing and flush water lines.

Maintenance
General
Periodically inspect the entire system for leakage and chafe on the tubing and hoses. Repair any leaks you find as soon as practical. Some crystal formation around the Clark Pump blocks is normal. Wipe down any salt encrusted areas with a damp cloth.
The Seawater Strainer
The sea water strainer’s stainless steel element should be inspected, removed, and cleaned as needed. Be careful to 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, rinse, and reassemble dry to impede corrosion. Check frequently during operation.
The Prefilter
Service the prefilter on a regular basis. The pressure will rise on the remote gauge when the
filter becomes dirty. Extremely dirty filters will harm system performance and may cause the feed pump to cycle on the high pressure switch. Do not leave dirty filters in the machine during long idle periods, as biological contamination could result.
To service the filters, shut off the service valve, open the housing, and discard the old filter.
Clean out the housing bowl, reassemble the housing with a new 5 micron filter element. Leave dry until next startup.
Use only Spectra approved filters or you may void your warranty. The filters may be
cleaned several times with a soft brush and water in a bucket. Occasionally, lightly lube the filter housing O-ring with silicone grease.
Oil Water Separator (Optional)
To install oil water separator capability 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 mem-
brane by removing chlorine from the fresh flush water. Use only a Spectra replacement!
The Feed Pump and Clark Pump
The feed water pump and the Clark Pump require no routine maintenance except inspection for leaks. Tighten any hose clamps or fittings the 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 silicone sea, and tightened with two wrenches very tightly.
20
Page 21
The Membranes
The membranes need to be cleaned only when feed pressure begins to rise due to fouling or
the product quality degrades. The leading cause of fouling is from biological growth that occurs when the system is left unused without flushing or pickling. Fouling from mineral scaling can happen during operation under certain sea water conditions, and from rust. Monitor the product salinity and feed pressure for higher than normal readings for the exist­ing conditions. Other conditions can cause high pressure such as cold feed water or clogged filters. Low product flow is usually due to low voltage, damaged feed pump or Clark Pump. Look for all other causes before cleaning the membrane. Membrane life can be shortened by excessive cleaning.
There are two types of cleaners: acid and alkaline. The acid cleaner (SC-3) will remove min-
eral scaling. The alkaline cleaner (SC-2) is used to remove biological by-products, oil, and dirt particles that get past the prefilters. If membrane performance is reduced and they have not been “pickled” recently, cleaning with both chemicals is recommended. The acid cleaner should be used first. If the membrane fails to respond to both cleanings, this is an indication of another problem with the system, or that it is time to replace the membrane. Contact Spectra Watermakers before removing a membrane.
Membrane Cleaning
For normal cleaning, the SC-3 Acid Cleaning Compound is used first, then the SC-2 Alkaline Cleaning Compound. If known bio-fouling is present, the SC-2 may be used first. Using hot wa­ter if possible, up to 120° (45C) is recommended as it greatly enhances the ability of the cleaners to do their jobs.
If the history of the system is unknown or has been left “unpickled” for an extended length of time and biological growth is present, it is recommended that the system is cleaned with SC-2, using an alternate source of unchlorinated fresh water before the system is run under pressure. A simple test can be performed to see if biological growth has occurred. Before running the sys­tem, remove the prefilters and examine their condition If the housings are full of smelly discol­ored water, the system was not properly stored. Install clean prefilters if they were bad. Next check the membrane. Detach the brine discharge hose and lead to a bucket. Open the pressure relief valve one turn, and manually run the system for 30 seconds. Examine the brine water: if it’s discolored and smells bad, perform an SC-2 cleaning with an alternate source of unchlori­nated water before running the system pressurized. If the brine is fairly clean, the system can be purged, run normally, and checked for performance. Clean the membranes only if performance is reduced.
Heating the water is preferable. One way to do this is to find a camp stove and use a large stainless steel pot to heat the solution in. The cleaning solution throughout the system will heat as it circulates in and out of the pot. An alternative is to heat the one or two gallons of initial water to 120° on the main stove before mixing in the cleaner and circulating it into the system. Periodi­cally stop and reheat the solution.
Perform the cleaning procedures while the ship is in acceptable sea water for purging and testing.
21
Page 22
Note: Procedures are the same for the SC-2 and SC-3 cleaners
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 water to have the proper solution. An av­erage of two gallons (8L) of water is already present inside a 150 system. This water has to be fig­ured into the mixture. A Ventura 150 system will use one container of compound,
Cleaning Procedure:
1. Close the service valve, open the flush valve and run the feed pump for 4 minutes to
flush the system. Stop the pump and close the flush valve.
2. Connect your inlet service hose and the brine discharge service hose. Open the flush valve
and start the pump until you get a gallon (4L) of water in the bucket.
3. Turn the service valve to the service position.
4. Make sure that the pressure relief valve is OPEN (un-pressurized).
5. Mix the cleaning chemical in the bucket.
6. Start the system and circulate the chemical through the system for the required time.
7. Stop the pump, replace the brine discharge hose and start the pump until the bucket is
empty. Stop the pump and rotate the service valve back to the run position. Restart the pump and run for 20 minutes to flush the chemicals out of the system. (DO NOT CLOSE the pressure relief valve!)
8. The system should now be restarted to make water, fresh water flushed, or stored.

MISC-1 DWYER FLOW METER SERVICE
The mechanical flow meter (part no. PL-FMT-XX) used on our manual watermakers can be opened for cleaning if it gets hard to read, or if the little ball in the flow meter is stuck at the bottom. If the ball is stuck, first try giving it a tap to break it loose.
The flow meter will come completely apart for cleaning. First, remove the meter from the panel.
ext, remove the four small screws th at hold the stainless steel bracket in place. Carefully pry
off the bracket. On the very top of the meter is a clear plastic slide-off cover that covers a clear
lastic allen screw. Use a flat-bl aded screwdriver to push the cover off. Holding the meter upright, remove the allen screw with a ¼” allen wrench. Invert the flow meter and catch the ball as it falls out. Now you can get inside and clean things up. You can use tooth paste or plastic window polish to polish the inside using a small bottle brush. 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 little Vaseline or water maker grease to ease assembly. These are standard O-rings and should be available at most larger auto parts or bearing stores. Reassemble in reverse.

The reverse osmosis membrane is permeable by many gases including hydrogen sulfide, the gas that causes rotten eggs to smell the way they do. If there are bad odors in the feed water they will go through the membrane and the product water will be affected. Usually the source of the
.
odor is from the decay of planktonic creatures trapped in the sea strainer and prefilters tiny oxygen loving creatures soon suffocate and die inside the prefilter housings when the unit is shut down. Once all the available oxygen is consumed, anaerobic bacteria begin to grow, causing the odor. If a unit being used frequently begins to make smelly water, usually the
refilters are the source of the problem. This occurs in a week or two in cold climates, but in less than one night in very warm waters like the Sea of Cortes or the Red Sea. These bacteria can spread throughout the watermaker, and begin to grow on the membrane, causing poor water quality and high feed pressures.
Filling the system with fresh water after every use greatly slows this process, allowing the automated Spectra units to operate with less frequent prefilter changes, but units operated for only an hour or so each day will probably need to have the filters changed due to odor before they are dirty enough to restrict water flow. Prefilters can be cleaned. We recommend that you have three sets in service: one in the unit, one set soaking overnight in a bucket of clean fresh or salt water, and one set drying for the next use. After shutting down the unit, remove the used
refilters and install the dry set. Leave the housings full of air until the next use. On non­automated systems, open the pressure relief when starting if there is a lot of air in the system until the air is cleared out through the brine overboard. The filters will get just as clean when soaked in sea water, but dry much faster if soaked in fresh. Given gentle handling, prefilters can be reused many times.
Bad smelling product water is usually caused by bad smelling feed water, but can also be caused
y a fouled membrane if the membrane has been left unpickled. If the unit makes smelly but not salty water after a long idle period and the prefilters are new, the smell can be eliminated by running the unit unpressurized for an hour or so to flush the membrane.
Odors in the product water can also be eliminated by adding a charcoal filter in the product water line. Spectra offers a product water filter kit (part no. KIT-FLT-CC).

OP-3 CHEMICALS 101
p
Spectra Systems use four types of chemicals: S C-1, SC-2, SC-3, and propylene glycol antifreeze.
NOTE: Never use any chemicals with the system pressurized! Always open the pressure relief
1
valve before pressurizing and making water.
The SC-1 is for storage only. It is no longer used as a cleaning chemical. To prepare the system for storage, first do a fresh water flush until the brine discharge is below 1000 ppm or does not taste salty. Mix one jar of SC-1 with 1 to 2 gallons of product or dechlorinated fresh water in a bucket and circulate UNPRESSURIZED with the fresh water in the system for 10 minutes, then discard. The system should be repickled every six months in warm conditions, and every eight months in cooler conditions.
The Spectra systems should be stored with propylene glycol if freezing could occur. This is the food grade antifreeze used to winterize RVs, boats and cabins. This works very well for storing in warm climates and is good for one year. See “OP-1 Winterizing or Pickling With Antifreeze” for instructions on this procedure.
/2 turn. Always purge a system containing chemicals for at least 20 minutes unpressurized
NOTE: Do not use metasodium-bisulfate
, the standard chemical used to store most watermakers.
This chemical will damage the Clark Pump and void the warranty.
CLEANERS: Cleaning can be detrimental to the membrane and shorten its life. Avoid unnecessary cleaning. Avoid cleaning as a diagnostic tool.
SC-2 is an alkaline cleaner used to remove light oil, grime and biological growth. It is most
effective if heated to 120
o
F. On a boat, this is not easy to do. If not heated, circulate for 2 hours and let set for several hours and recirculate for on e hour and discard. In most cases the water quality will increase in PPM after an SC-2 cleaning. After a few hours it should recover to near the PPM it produced before the cleaning
.
SC-3 is an acid cleaner used to remove mineral and scale deposits. This is used in the same way as the SC-2. In most cases this is used first, and if no results are achieved, proceed with the SC-
2. SC-3 will in most cases lower the product PPM and over all pressures. Scaling is a slow
rocess 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.

PF-2 CHARCOAL FILTERS
p
p
The function of the charcoal filter element (part no. FT-FTC-CC) is to remove any chlorine in the fresh water flush water supply. The reverse osmosis membrane can only handle small amounts of chlorine for short periods without damage. If the fresh water flush water contains chlorine, the membrane will be exposed to it for days at a time and the membrane will begin to
roduce high salinity product. We do not specify a micron rating for the charcoal filter because
the other filters are downstream of the charcoal filter and still provide all the necessary
articulate filtering.
The charcoal filter we supply removes 99.7% of the chlorine. Beware when buying other charcoal filters. If they don’t specify the percentage of chlorine removed, don’t use them. The cheap ones may remove only 60% or 70%. Also, there are aftermarket filters which are very close to, but not exactly, the same dimensions that will not seal properly in the housing. So if you skimp on the charcoal filter you will toast a $500.00 membrane on the first flush. The other factor is the flow rate that the filter can handle. Because the chlorine is deactivated by a chemical reaction with the charcoal, it must remain in contact with the charcoal for sufficient period of time for the reaction to be complete. The filters we use can handle 1.5 gallons (6 liters) per minute flow, and are good for 3000 gallons (12,000 liters) at 1.5 GPM, or six months, whichever comes first. Regardless of the flow, the charcoal loses its effectiveness after six months.

PF-3 PREFILTERS– ShurFlo
Up to four different filters are used on all Spectra Systems using ShurFlo feed pumps to ensure that no damaging foreign materials enter the system. There are 2 or 3 filters in the system to clean the feed water of abrasive materials while the system is in operation, and an additional filter to prevent the entrance of chlorine during fresh water flushing.
During normal operation, the feed water is filtered in two stages. First it enters a fine mesh metal sea strainer, which protects the feed pump from damage due to foreign materials and lar­ger sea creatures. After passing through the pump, the feed water enters the filter housings con­taining 20 and 5 micron elements. These filters remove very fine particles which could damage the Clark Pump and shorten membrane life. Some units have only the 5 micron filter.
Cleaning 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 relatively short period of time in bio­logically fertile near-shore waters, the prefilters will plug up, the pressure drop across the filters will increase, production and quality will drop, and the system will sense plugged filters and give a “Service Prefilters” or “Check Strainer” alarm, if so equipped. Plugged filters can be cleaned several times by soaking in a bucket, towing behind the boat at moderate speeds, or hosing them off. 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 filters long before the elements plug up, and the bacteria involved in the decay will cause a “rotten egg” smell in the product water. This decay will set in over­night in tropical waters, or after a week or two in high latitudes. If handled gently and changed regularly before they get too smelly, filters in this service can last through dozens of cleanings. In crystal clear blue water conditions, the filters may need to be cleaned much less frequently. The charcoal filter used in the fresh water flush system will not plug up unless you have some incredibly dirty domestic water in your boat. About six months after installation, the charcoal filter element will lose its effectiveness at removing any membrane-damaging chlorine which may be present in domestic water. Charcoal filter elements must be replaced every six months if there is ANY chance that chorine could be introduced into the flush water. To ensure that filter elements fit properly and remove chlorine effectively, they should be pur­chased at factory authorized dealers. Our element part number is FT-FTC-XX. The last two digits indicate the micron rating, e.g. FT-FTC-05 is for a 5 micron element. Charcoal elements are FT-FTC-CC.

MISC-3 ACCUMULATOR PRESSURE
All Spectra Watermakers except the Newport 700 and 1000 series are supplied with a pressure accumulator tank, (part no. PL-ACC-TK) to be installed in the feed water line between the pre­filters and the Clark Pump. In addition, the Catalina 300 and Newport 400 series also have an accumulator mounted inside the fresh water flush module.
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 ShurFlo pump pressure cutout switches. The accumulators have an air valve on top similar to those found on car tires. This 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 tire pump or air compressor. You can experiment with the exact pressure that will give the best pulsation dampening on your installation.
The purpose of the fresh water flush accumulator is to allow a steady flow of 1.5 gallons per minute of flush water through the charcoal filter. Because the feed pump on the 300 and 400 hundred series exceeds this maximum allowed flow rate, the controller turns it on and off, to reduce the overall flow rate. The accumulator gives the water flowing through the charcoal fil­ter somewhere to go while the feed pump is cycled off. The flush water accumulator should be preloaded to 5 psi (.35 bar).

SF-1 SHURFLO PUMP WON’T RUN
If the pump has power to it (the fan runs), but the pump itself won’t run, the first thing to check is the pressure switch. The pressure switch (part no. EL-FP-PS) is located on the wet end of the pump and has two red wires plugged into it. 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.
If the pump will not run with the pressure switch jumped, then it is most likely a problem with the brushes or the overheat protection 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 plastic brush holder. The thermal switch is located on one of the brush leads. With an ohmmeter, check for continuity 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.
If any corrosion is apparent, the brushes may be sticking. Once apart, clean all the carbon dust from all the parts. Clean the commutator with light sand paper. 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 it 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. This will at least keep you going until the motor can be replaced if necessary. 6/03/04

SF-2 ADJUST SHURFLO PRESSURE SWITCH
The ShurFlo feed pumps are equipped with a high pressure cut out switch (part no. EL-FP-PS). This is the small black unit on the end of the wetted end of the pump head (part no. PL-PMP­SFPH) where the two red wires connect. If the pressure switch is not properly adjusted, the pump may cut out each time the Clark Pump cycles and the feed pressure spikes. When this happens, the production will drop and an unusual noise will be heard when operating on two pumps, but the system will function normally during single pump operation on either pump. The points in the switch will fail fairly quickly if set too low because of the constant arcing from cutting out each time the Clark Pump shifts.
For all systems except the Gulfstream, the feed pump pressure switches should be set to shut off at 125 psi (8.5 bar) as follows: On the very center of the switch is a small 5/64” allen screw. Run the system on pump one and close the brine discharge valve (1/2 way 90 deg) to block the flow. Watch the pressure gauge and adjust the pressure switch to shut off at 125 psi. Repeat for pump two. Turn the allen screw clockwise to increase the cut off set point.
Gulfstream models could experience seal failures in the manifold if pressurized too high. For this reason the pump should be removed from the system and the switch adjusted using a sepa­rate pressure gauge. If replacing a feed pump or pump head for a Gulfstream model, arrange to preset the switch before installation.

Z-BRANE
OPERATION
MANUAL

Page 34
The Z-Brane is a revolutionary product which incorporates Z-Guard High Voltage Ca­pacitive technology into the membrane pressure vessel. Always active, the Z-Brane cre­ates an environment that is unfriendly to bio-film and bacteria. The Z technology also as­sists in the prevention of scale formation on the membrane surfaces. The Z-Brane allows the system to be shut down or decommissioned for extended periods of time without chemicals or preservatives. The Z-Brane will not prevent freezing so that in cold climates propylene glycol is still required.
The Z-Brane system is integrated with the watermaker unit and only requires continuous 12Vor 24V DC power to be operative. The installation of the Z-Brane only consists of wiring the power supply to a continuous source The Z-brane power supply can tolerate voltages between 10V and 28V DC.
NOTE: There is no reason to open the transformer enclosure. DO NOT service this unit without disconnecting the power source! There may be high voltage present.
It is recommended that the Z-Brane be connected to a discreet continuous power source. The power must be on during the time that the system is operation and during the time the Z-Brane is used for membrane storage. If the power is obtained from the MPC then the MPC must be powered up at all times during storage. This may not be desirable.
Fuse the power at the source with a 5 amp fuse or circuit breaker.

Operation
During normal operation the red LED should be on. Power needs to be supplied to the Z­Brane unit for as long as you wish to have the bio-fouling and scale protection. We recom­mend that your watermaker be flushed after each use not only to protect the membrane but to prevent corrosion in the feed water system. To achieve full effectiveness thoroughly fresh water flush the watermaker several times before leaving the vessel.
The Z-Brane may be de-powered if the system is stored with chemicals or winterized with glycol.
