WHAT’S INCLUDED IN YOUR KIT Standard Kit (Model G-20): Both Standard & Premium Kits: • (1) 40” reverse osmosis membrane with • (1) Control panel housing • (1) Seawater lift pump (1) 1HP 115V/230V AC pump • (1) Starter switch • (1) Pre-filter housing with wrench Premium Kit (Model G-40): • (1) Pre-filter • (2) 40” reverse osmosis membranes with • 25’ of high pressure tubing housings • 10’ of 1/4” low pressure hose (1) 2HP 115V/230V AC pump • 50’ of 1/2” low pressure hose • 10’ of
CONTROL PANEL INSTALLATION ►►►Prior to mounting the Control Panel, connect 1/4” hose to the Pre-filter Gauge on the back of the Control Panel. Leave the hose loose for connection to the Pre-filter Housing later. ❶ Mount the Control Panel in a convenient location; the panel should be easily accessible and you should have a clear view of the gauges when you’re running the watermaker. It should be as close as possible to the Membrane and to the High Pressure Pump.
PRE-FILTER INSTALLATION The Pre-filter Housing should be located for easy access, away from any electronics or other surfaces that cannot get wet. ❶ Mount the Pre-filter Housing to a bulkhead using the supplied bracket. ►►►Be sure to leave enough room below the housing to allow for Pre-filter changes. ❷ Glue PVC fittings with PVC glue as required per your installation. ❸ Run a 1/2” hose from the intake side of the Pre-filter Housing to the hose barb on the Control Panel labeled “To H.P. pump.
HIGH PRESSURE PUMP INSTALLATION Bracket Requirements Before installing the high pressure pump, you’ll need a bracket to mount it to the generator. • The pump must be mounted as level as possible with the oil dipstick on top of the unit. • The pump can be turned in either direction. • The bracket should be made of mild steel and painted prior to installation. • The bracket should include a method for tensioning the belt.
Once the pump has been mounted and the belt has been installed, you’re ready to make the electrical and plumbing connections for the High Pressure Pump. ❶ Fill the pump with 9.81 oz. ISO 100 - NA 30 weight hydraulic oil. ❷ Connect the [+] wire from the magnetic clutch to the wiring harness on the Control Panel using 12-gauge tinned wire. ❸ If the generator is not grounded to the [-] terminal of the battery, you will need to run an additional wire from the pump to your [-] battery buss.
MEMBRANE INSTALLATION The Membrane should be installed horizontally within a reasonable distance of the Control Panel and the High Pressure Pump. When selecting a location for the Membrane, be sure to account for the additional space required for hose fittings. Brine ►►►The Membrane should not be near sources of heat, Product Input such as the generator or refrigeration. The Membrane requires 2 mounting brackets.
RUNNING TUBING AND HOSES High Pressure Tubing Your watermaker comes with 25’ of high pressure tubing and 4 Swagelok field-attachable fittings. If your installation will require more than 25’ of tubing, please contact us. When planning your installation and high pressure tubing runs, be aware that the maximum bend radius for the tubing is 12”. ►►►When running high pressure tubing in bilges or near heat sources, it is recommended that you install 3/4” reinforced hose over the high pressure tubing.
❷ Blow the tubing clear to eliminate any chips or dust created by cutting. ❸ Once you’ve installed ends fittings on the high pressure tubing, connect tubing to the High Pressure Pump and Membrane using Teflon tape to seal the threads. ❹ Install the high pressure tubing from the Membrane to the port on the Control Panel labeled “H.P. In.” Install end fittings per the “Swagelok High Pressure Fitting Installation” instructions. Connect and tighten fittings.
Low Pressure Hose ❶ Install a 1/2” hose run from the output of the Pre-filter Housing to the inlet of the High Pressure Pump, securing with hose clamps. ❷ Install a 1/2” hose run from the Brine Dump port on the Control Panel to the through-hull. ❸ Install a second hose run from the second Brine Dump port on the Control Panel to the pressure relief valve located on the High Pressure Pump.
INITIAL SYSTEM START-UP Now that you have completed installation, you are almost ready to start the watermaker for the first time. Pre Start-up Checklist □ All hose fittings are secured with hose clamps. □ Through-hulls are open. □ All wiring connections are secure. □ Breaker is on. □ Belt tension on High Pressure Pump is adjusted. □ Verify Pressure Adjustment Needle Valve is turned counterclockwise to reduce pressure.
Setting The Pressure Relief Valve WARNING: Be sure that the High Pressure Pump needle valve is turned fully counterclockwise to the minimum PSI. ❶ Slowly increase pressure to 950 psi by turning the Pressure Adjustment Needle Valve on the Control Panel clockwise. ❷ Using an Allen wrench, adjust the pressure relief valve until it opens. You should see water flow into the clear bypass hose and a slight drop in pressure on the Membrane Pressure Gauge.
