  • Page 10: Introduction

    INTRODUCTION INTRODUCTION SYSTEM DESCRIPTION Village Marine Tec’s (VMT ) Pure Water watermakers are well-engineered reverse osmosis (RO) systems, designed  and built for simple operations and maintenance for the cruising sailor, sport fisherman, or working vessels where space is at a premium. These self-contained AC desalination systems will produce sixteen to eighty-three gallons per hour (GPH) of freshwater from the sea (gallon production will vary based upon water temperature, salinity, and model of the RO system).

  • Page 11: Unpacking And Handling

    INTRODUCTION UNPACKING AND HANDLING The Pure Water reverse osmosis units are shipped pre-assembled. There are no special instructions towards unpacking and handling of the watermaker system. Inspect the RO unit to verify it was not damaged in transit. Also, please refer to the plumbing diagram in Section 9.0: DRAWINGS AND DIAGRAMS to verify all components for the watermaker are shipped prior to installation.

  • Page 14: To Connect Plumbing

    INSTALLATION The Pure Water FRAME SHOULD NOT SHARE a through-hull feedwater intake. Avoid connecting the inlet piping to any water line which services an engine or other equipment. Air could be drawn through the unit causing damage to the RO unit’s pumps, as well as VOIDING the RO unit’s warranty with VMT.

  • Page 21: General Theory Of Operation

    GENERAL THEORY GENERAL THEORY OF OPERATION REVERSE OSMOSIS THEORY Reverse osmosis, like many other practical scientific methods, was developed from processes first observed in nature. Osmosis is a naturally occurring phenomenon in which a semi-permeable membrane separates a pure and a concentrated solution (a semi-permeable membrane is defined as one that preferentially passes a particular substance).

  • Page 22: Product Water Quality Standards

    GENERAL THEORY In a Reverse Osmosis desalination system, most of the dissolved solids do not pass through the membrane but are instead carried along the membrane surface. This rejected water, referred to as brine, becomes increasingly more concentrated as it flows across the surface of the membranes and is eventually piped to drain.

  • Page 24: Temperature Correction Factor

    GENERAL THEORY 3.4a TEMPERATURE CORRECTION FACTOR As previously described, the output capacity of any RO unit is highly dependent on feedwater temperature. In order to quantify this relationship, operational data has been utilized to develop Temperature Correction Factors (TCF). The TCF (which is compensated to 25°C/77°F) is used to determine what part of any change in system output flow is due to variations in feedwater temperature alone.

    GENERAL THEORY Installed as an option, the Remote Control Center (RCC) provides remote control and monitoring of all important unit functions and operating parameters (Figure 3.4) from a remote location. The RCC has a similar configuration as the MCC with the exception of the Message Center and Reset Pushbutton. PUSHBUTTON AND DISPLAY DESCRIPTIONS Refer to the numerical callouts of Figures 3.2-3.5 for reference of the following pushbutton and displays explanation of the Water Quality Monitor, Master Control Center, and Remote Control Center panels.

    MAINTENANCE Step 8: Gradually turn the High Pressure Bypass Valve (Black Valve) to NORMAL/RO position. The pressure gauge should steadily rise to a reading of 800 psi. NOTE: When the High Pressure Bypass valve is closed, the salinity of the initial permeate produced will be relatively high and will probably be enough to activate the salinity alarm.

  • Page 48 MAINTENANCE Step 6: Start the High Pressure Pump by pressing the H PMP button located on the Master Control Center (or on the Remote Control Center). Step 7: Upon start-up inspect all plumbing connections in the unit for leakage. Varying temperatures during shipment may cause plumbing connections to seep when starting the RO unit for the first time.

  • Page 49: Maintenance

    MAINTENANCE MAINTENANCE The service life of most system equipment is directly related to proper maintenance and to the raw water inlet conditions. Improper maintenance will reduce the life expectancy of the major unit components (such as the membranes, filters and pumps) as well as the reliability of the unit as a whole. Under normal conditions a reverse osmosis membrane (which is the major consumable item) should have an effective service life somewhere between 3 and 5 years.

  • Page 50: To Flush The Pure Water Unit

    MAINTENANCE TO FLUSH THE PURE WATER UNIT Step 1: For Units with Manual Freshwater Flush Valve Assembly: Turn ON your water pressure and watermaker breakers on main electrical panel. Turn the High Pressure Bypass Valve to CLEANING (ensuring zero pressure in system). Verify the gray Cleaning Valve is positioned to NORMAL/REVERSE OSMOSIS position.

  • Page 51: Membrane Cleaning

    MAINTENANCE MEMBRANE CLEANING This section is to guide the operator in the periodic chemical cleaning of the RO membrane elements used in the PW400-PW2000 unit. The basic procedure for all cleaning and preservative treatments is the same – a specific chemical solution is circulated through the system for a pre-determined length of time.

  • Page 52: Steps For Chemical Cleaning #1: High Ph Cleaner

    MAINTENANCE STEPS FOR CHEMICAL CLEANING #1: HIGH pH CLEANER Step 1: Freshwater Flush the watermaker so it is filled with fresh water, NOT seawater. To flush the Pure Water, refer to instructions in Section 5.1: TO FLUSH THE PURE WATER UNIT. Step 2: Dissolve the appropriate amount of Cleaning Chemical #1 (see Table 5.2) in one gallon of freshwater.

  • Page 53: Long Term Storage / Preservation Procedure

    MAINTENANCE LONG TERM STORAGE / PRESERVATION PROCEDURE During periods when the RO unit is to be shut down for an extended period of time, it is necessary to re- flush the unit every three weeks OR to circulate a preservative solution through the membrane to prevent the growth of biological organisms.

  • Page 54: Oil Change Procedure

    MAINTENANCE OIL CHANGE PROCEDURE An oil change is recommended after the first 50 hours of RO use. Subsequent oil changes are to be performed every 500-hour intervals OR changed annually. Change oil any time moisture is detected or if oil is cloudy. For additional pump information, refer to Section 11: MANUFACTURER’S LITERATURE at the back of this manual.

  • Page 55: Motor Lubrication

    MAINTENANCE RO MOTOR LUBRICATION NOTE: Motors should be re-lubricated at least once a year. Step 1: Locate the grease fittings on the motor (Refer to Figure 5.2). Use a clean cloth to wipe fittings clean. Figure 5.2: Electric Motor - Grease Fitting Locations. Step 2: Add 2-3 strokes of grease using a low pressure grease gun (see Table 5.3 for grease type).

Remove the vessel from the PW unit and continue on a workbench. Step 2: Remove the eight fasteners and cap ring holding each end plug with an allen wrench (refer to Figure 6.1).

  • Page 58: Pressure Vessel Assembly

    MEMBRANE REPLACEMENT NEVER FORCE A MEMBRANE OUT OF A PRESSURE VESSEL BY APPLYING PRESSURE ON THE PRODUCT WATER TUBE (CENTER TUBE), AS THIS WILL DAMAGE THE MEMBRANE. IF MEMBRANE IS DIFFICULT TO REMOVE, USE A 2” DIAMETER PLASTIC PIPE (PVC) TO APPLY PRESSURE ON THE PROTECTED END OF THE MEMBRANE.

  • Page 59: Freeze Protection

    FREEZE PROTECTION FREEZE PROTECTION There is a high probability of damaging your RO by exposing it to severe cold or icy conditions. The following procedure will protect your RO against freeze damage. DO NOT USE ETHYLENE GLYCOL (FOUND IN AUTOMOTIVE ANTIFREEZE PRODUCTS) TOWARDS FREEZE PROTECTING YOUR RO.
  • Page 60 FREEZE PROTECTION ALTERNATIVE FREEZE PROTECTION METHOD Instead of applying propylene glycol to the RO system, an alternative method to freeze protect the RO is available. Step 1: Perform a Chemical #3 preservation to the unit. To preserve the PURE WATER, refer to instructions in SECTION 5.4: STEPS FOR PRESERVATION CHEMICAL #3 Step 2: Remove membrane vessels from the boat, placing caps over the fittings.
