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 po

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 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.

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

Feed Pump Relocation 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. Cooling fan Machine Screws Heat sink With the pump on a flat surface. Remove the

Product Water Plumbing 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. Product to tank. Route the product water into the top of the tank, or a tee

Product Tube Fitting Assembly Spacer O-ring Grab Ring Body Nut Tubing Step 1: Dissemble fitting components 1/2" max 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. Step 3: Gently fit the tube into the body and loosely thread on the nut. Step 4: Push

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. L

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, rea

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 t

Ventura MPC New System Start-Up and Testing 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. First check that: • Thru-hull inlet valve is open and the brine discharge va

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 P
