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 reliability. 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 improved since. It holds a lifetime warranty for the original
purchaser! It is built of modern non-corroding composites.

Getting Started
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 components 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 tubing and hose before starting so additional parts may be ordered.

Installation Basics
Thruhull
Not Supplied.
• 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
Flow
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 conditions. 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 debris 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.
Wiring
• Pay attention to wire size or system performance will be impaired
• Perform wiring to UL, ABYC, CE or applicable standards

Feed Pump Relocation
If you do not have adequate space to install the feed pump inlet module it is possible to remove 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 holding the pump to the module.

screws that hold the pump head on. See Fig1
Re-orient the pump head 120 degrees. See Fig2
Reinstall the screws and tighten firmly. See Fig3
Now the feed pump may be installed where you wish.
Do not install with the pump head over the motor incase of leaks. Wire size may have to be increased if
wire runs are longer.

Product Water Plumbing
Product water tubing is 1/4”(6mm) on the Ventura 150 models. See the Parker tube fitting assembly 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.
Product to tank.
Route the product water into the top of the tank, or a tee in the
water tank fill hose.
DO NOT! feed into a vent line, a manifold or the bottom of the
tank. Make sure that there is no restriction in this piping.

Step 1: Dissemble fitting components
Step 2:
Install the Nut first then use the bevelled side of the Spacer to push the
Grab Ring onto the tube no more than 1/2". Slip the O-ring over the tube
to hold the Spacer in place. If the Grab Ring is pushed too far, trim back
the tube so about 1/4" of tube extends past the O-ring.

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 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 installing 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!

Tank Switch Installation and Operation:
There are two sets of terminals on the MPC-5000 PCB that can be used in four different configurations to automatically start and stop the watermaker, or to automatically stop the watermaker 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 pushing 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 stopping it by holding down the Autorun button.
If the owner prefers to install the automatic shutoff feature without the automatic start up option, only the tank full switch is used. A jumper must be placed between the tank empty terminals (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 separate 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.
