Introduction to the Ventura 150 MPC
The Ventura represents the finest watermaker for small and midsized yachts available today. The Spectra
Clark Pump is matched to a 21” high rejection membrane. Properly installed and maintained it will supply
years of reliable service. The MPC-5000 control provides the ultimate in operational convenience and reli-
ability. Note that prudent operation is required with any marine equipment. Always maintain enough reserve
water to get safely into your next port.
The Spectra High Pressure Intensifier, known as the Clark
Pump, was introduced in 1997 and has continually im-
proved since. It holds a lifetime warranty for the original
purchaser! It is built of modern non-corroding composites. Front View

Unpack the system and inspect it to make sure that it has not been damaged in shipment.
Refer to the shipping list for your system to make sure you have received all of the compo-
nents listed. Do not discard any packaging until you have found and identified all of the
parts. The small installation parts are listed on the kit list.
Warning! We will not be held responsible for shortages and/or freight damage that are
not reported within thirty days of the ship date.
Study the system plumbing and wiring diagrams before beginning your installation. This
will assist you in understanding the function of each component.
Layout the system. Before starting the installation, identify the location where each module
and component will be placed. Insure that there is proper clearance around the components
for removal of filters and system service. Also check to make sure you have adequate tub-
ing and hose before starting so additional parts may be ordered.

Installation Basics
•Read the directions!
•Avoid tight hose bends and excessive runs
•Use heavy gauge wire
•Install feed pump as low as possible
•Use a dedicated thruhull with scoop type strainer
Thru-hulls
It is mandatory that a dedicated 1/2” to 3/4” forward facing scoop type intake thru-hull and
seacock be installed. Install the intake for the system close to the middle and as far below the
water line as possible. Thru-hulls in the bow area are susceptible to air intake in rough condi-
tions. Sharing a thru-hull with another system is not acceptable and will void the warranty.
Sharing a thru-hull can introduce unforeseen problems such as intermittent flow restriction,
air bubbles, and contaminates. For racing boats and high speed power boats above 15 knots a
retractable snorkel-type thru-hull fitting is preferred to be able to pick up water away from
the hull.
Do not install the intake close to or downstream of a head discharge. Install as far below the
waterline and as close to center line as possible to avoid contamination and air induction.
The brine discharge thru-hull should be mounted above the waterline, in or just above the
boot stripe to minimize water lift.
Double clamp all hose connections below the waterline.
Pipe Fitting Instruction
Plastic to plastic fittings should have 3 to 4 wraps of Teflon tape and will thread almost all
the way in.
Avoid getting dirt or debris into the piping or hoses during assembly. A small bit of de-
bris can stop the system! Avoid getting tape over the end of fittings that might get into the
system. To insure this does not happen, leave the very first thread uncoated.
Avoid restrictions or long runs on the entire inlet side of the plumbing from the thru hull to
the main feed pump module.
Prevent tight bends and excessive elbows. Any restrictions will hamper system performance.
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 after several hours of
operation.

If you do not have adequate space to install the feed pump inlet module it is possible to re-
move and relocate the feed pump. Before you install the module, disconnect the hose that
connects the feed pump to the module plumbing. Remove the cooling fan and the heat sink
from the pump. Both are friction fits with no fasteners. Remove the 4 machine screws hold-
ing the pump to the module.

Product water tubing is 1/4”(6mm) on the Ventura 150 models. See the Parker tube fitting as-
sembly diagram next page. Product water is pre-plumbed from the membrane into the electric
diversion valve. The diversion valve will reject product water into the overboard brine stream
until good quality is measured by the MPC-5000 control. Product water is then diverted into the
fresh water tank.

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 pre-
installed 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 with an O-ring and should be seated all the way in, but need
only to be snug, not tight as with tapered threads. Hold the fitting with a wrench while in-
stalling the tube.
The fittings on the Clark pump have an O-ring seal and can be re-oriented 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!
The correct torque is specification is 85 foot pounds
Tighten 1-2/3 turns (10 flats of the

Tank Switch Installation and Operation:
There are two sets of terminals on the MPC-5000 PCB that can be used in four different con-
figurations to automatically start and stop the watermaker, or to automatically stop the water-
maker when the tank(s) are full without the auto start feature. These terminals are on the
green ten pin connector and are labeled “Float Switch 1” and “Float Switch 2.” Float Switch
1 is the tank full switch and Float Switch 2 is the tank empty switch.
If the unit is wired for both Autostart and Autostop, it can be put into AutoFill Mode by push-
ing and holding the Auto Run switch on the MPC-5000 display. In this mode the watermaker
will start whenever the water level drops below the tank empty switch, so that it is open (not
conducting electricity). When the tank fills up and both the tank full switch and the tank
empty switch have remained closed for two minutes, the watermaker will shut down and flush
itself. The watermaker will start back up when the water level drops below the tank empty
switch and it remains open for 2 minutes. This configuration allows for completely automatic
operation. If the watermaker does not need to start up within five days it will automatically do
a fresh water flush. AutoFill mode can be ended by pushing the stop button or the Autoflush
button. If the watermaker is in Autorun mode it can be put into Autofill mode without stop-
ping it by holding down the Autorun button.
If the owner prefers to install the automatic shutoff feature without the automatic start up op-
tion, only the tank full switch is used. A jumper must be placed between the tank empty ter-
minals (Float Switch 2) in place of the tank empty switch, because the watermaker will only
shut down if both sets of terminals are closed. To use this mode the watermaker must be
started up with the Stop/Start button or the Autorun button. After the unit starts up, then press
and hold the Autorun button until the display reads “Auto Fill Mode”. The watermaker will
fill the tank and automatically enter Autoflush mode.
It is possible to use the autofill feature with 2 tanks. A double throw electrical switch must be
installed in a convenient location. If only the single tank full switch is installed in each tank,
connect the wire from Float Switch 1 terminal “1” to the common on the switch and run sepa-
rate wires from the switch to each tank switch. The second wires can both be run to the Float
Switch 1 terminal 2. If you are using two switches in each tank, you will need a double pole
double throw switch.
Note: If the Automatic startup is enabled the watermaker may start at any time. Because no
one may be available to check for oil in the water around the boat, it is recommended that an
oil-water separator, part number FT-FTC-OW be installed in place of the 20 micron filter.

Avoid running the Ventura system if the vessel is in contaminated water, such as in a harbor
or canal. The system should be fully tested before leaving port. 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.
•Thru-hull inlet valve is open and the brine discharge valve is open.
•All of your hose connections are tight.
•The green tag with the spacer under the pressre relief valve has been removed.
•The pressure relief valve is open 1/2 turn.
•The switch on the MPC control box is set to the“Auto” position.
First check that:
Ventura MPC New System Start-Up and Testing
Open 1/2 Turn when Purging Chemicals!Remove Tag and Washer!
Power up the system by turning on the cir-
cuit breaker. A message on the display will
read Open Pressure Relief Valve Now
Push the “Auto Run” Button. The feed
pump will start and the message
“Purging Storage Solution” will appear.
Note: See Part 2 for instructions on dimming the display and programming from the display

19
3. The system is now in the operational mode. You may start and run your system as you
desire. You will not have to go through the purging mode unless you “de-power” the sys-
tem. If you do, you can bypass the purging mode by pushing “Stop” and “Auto Run”
buttons at the same time. It is best to use the “Auto Run” button which defaults to the
automatic fresh water rinse. If you shut down the system from the “Stop” button then use
the “Auto Store” button to effect a fresh water flush cycle.
Note: You can bypass the purge sequence and initiate a normal start at any time by
Pressing both “Auto Run” and “Stop” simultaneously. This will bypass the
purge sequence and enable a normal start.
If you must stop the purge sequence for any reason, the control will default
back to the beginning of the purging mode to protect your system.
Do not bypass the purge mode unless you are sure that the chemicals are
purged from the system or you will permanently damage the membrane.
1. After the purge sequence, the control will alarm with the message “Close pressure relief
valve”. Close the valve and proceed by pressing “Auto Run.”
2. The system is now running under pressure and making water. The display will read
“purging product water.” This mode dumps the product water overboard for ten min-
utes in case there is any residual chemicals in the membrane. Carefully inspect for leaks
over the entire system! Shut down the system and repair any leaks you find.
4. Check that the system is operating within its normal parameters. Compare with the chart
on the next page.
The system will go into a start mode and the feed pump will start shortly after. The system
should prime within 60-90 seconds. Check the strainer and the brine discharge for water
flow. There should be few bubbles anywhere in the intake hoses and the feed pump should
sound smooth after priming. After confirming that the system is primed, inspect for leaks.
Note: The reject light will be on whenever the
product water is being rejected or not being made.
When the product water is below 750 PPM the
green (Good) light will show that water is going
to the tank.
