EXCEEDED 4AQUA4AEROGEN WIRING INSTALLATION 5VOLTAGE REGULATIONThe output wires of the Aqua4gen water mode and the Aqua4aerogen in wind mode can be connected directly to theterminals of the battery that requires charging as shown on page 5 however if the terminal voltage of the battery is notcontinually monitored for over voltage 142v for 12v batteries and 284v for 24v batteries the battery can be Fitting an LVM voltage regulator will protect the battery from becoming over charged You may well have chosena voltage regulator when purchasing the Aqua4aerogen but we would recommend you look at page 9 SELECTING THECORRECT LVM VOLTAGE REGULATOR to make sure you have purchased the correct unit You may also consider installing an ammeter voltmeter or an amphour meter all are available from LVM part number asfollows LVM67 0 20A Ammeter LVM69 015v dc Voltmeter LVM200 Digital Amp Hour MeterVERY IMPORTANTIf you do not intend to use a LVM voltage regulator with the Aqua4aerogen it is extremely important that a similar type ofregulator is used ie It must be a shunt diverting type regulator that always keeps the Aqua4aerogen on loadYOU MUST NEVER USE A REGULATOR THAT SIMPLY TURNS OFF AND ON THE OUTPUT OF THE AQUAGENWHEN THE BATTERY IS FULLY CHARGED THIS CAN LEAVE THE AQUAGEN IN AN OPEN CIRCUIT CONDITIONWHICH WILL ALLOW THE TURBINE TO ROTATE AT VERY HIGH SPEED AND DAMAGE THE UNITOPERATING towrope with the turbine attached should be stored in a neat coil close to the Aqua4genOnce under way in deep water the turbinetow rope can be payed out It is safer to do this at around 12 Knots as therope will start to turn as soon as it enters the water The turbine is designed to surface at the following speedsStandard 115mm turbine blade 9 Knots Small 90mm turbine blade 11 the turbinetow rope can be achieved in two ways1 Slow yachtboat to 12 Knots then pull in towrope2 Make a tack to turn the yachtboat at 90 Deg to slow it down and bring along side the turbinetow ropeWhen pulling in the towrope it is very important that it is untwisted and coiled neatly ready to use againNote If for any reason the turbine surfaces before 9 knots when using the 115mm blades or 11 knots using the 90mmthis may be caused by your particular hull shape of the yacht creating an underwater wash effect add one or two25mm propeller shaft anodes to the turbine shaft close to the turbine hub or increase the length of the Aqua4gen water mode1 Check drive shackle bronze bushes for wear Apply a little marine greaseto the bronze bushes from time to time Typical life of the bronze bushes3000 7000 nautical miles2 Check the tow rope for wear at intervals particularly the area around the Dee Shackle and Eye bolt on the turbine shaft By cutting 1 to 2 inches off the rope a new section can be created3 Check tightness of the Dee Shackle pin4 Check all external electrical connections for tightness and corrosion5 Wash down the generator with fresh clean water to remove debris and salt deposits that can build upIf you experience a problem with your Aqua4gen contact LVM Products to determine the nature of the problem LVMProducts will send you replacement parts and instructions needed to repair the generator In the event that the generator isreturned for repairservice you will be notified of the cost for carrying out the work and will incur the transport costs 67AQUA4AEROGEN WIND MOUNTING

Clamp Plate on a flat surface blade sockets upwards and then insert the 6 blades concave side hollow sideupwards See Fig 1 Then place the Bossed Hub on top locating the blades in the sockets Insert the 6 off M6 screwswashers and nuts and at this stage only tighten the nuts sufficiently to lightly grip the blades See Fig 2 Turn each bladeuntil the indicator marks on the blade and hub align this sets the blade angle See Fig 3 Then finally fully tighten the nutsand push on plastic nut coversNOTE The fan assembly can now be stored ready for use when converting the Aqua4gen to be wind powered Fig 1 Fig 2 ALIGN MARKSTAIL UNIT Attach the tailfin onto the tail tube using theM4 X 25 long screws washers and M4 Nyloc nuts Fig 3INSTALLATION OF AQUA4AEROGEN WIND MOUNTINGPLEASE FOLLOW THESE PRECAUTIONS DURING INSTALLATION Choose a calm day Have someone available to help during installation1 Attach the push on connectors and covers supplied to one end of your output cable Observing polarity plug them into the Aqua4gen air mount output connectors Positive Red Negative Black2 Thread the output cable carefully through the centre of your mounting tube If the bottom of the tube is not accessible a hole must be drilled to enable the cable to be brought out Be sure to leave enough slack in the cable so that if necessary the generator can be removed 103 Locate the Aqu4aerogen wind mounting on top of your mounting tube and then fully tighten the M8 clamp bolt nut on the adaptor4 The tail assembly can now be inserted into the hole at the bottom of the Aqua4aerogen Wind Mounting ensuring that the tailfin is positioned vertically and tighten the M8 grub screws The tailfin assembly is generally left permanently in FROM WATER DRIVEN TO WIND DRIVENPLEASE FOLLOW THESE PRECAUTIONS DURING INSTALLATION Choose a calm day If possible have someone available to help during converting Do not install the blade assembly until the Aqua4gen is located and firmly tightened in the wind

the fan hub boss and fully tighten it into the main shaft using the Allen key supplied The black hub cover is then pushed onto the hub boss 11MAINTENANCE Aqu4aerogen wind mode The Aqua4aerogen in wind mode is designed to operate for long periods without needing any maintenance The life of thegenerator and its performance will be enhanced if periodic inspection is carried out For personal safety reasons beforecarrying out any inspection make sure you stop the generator from rotatingThe following should be checked every 6 months Check blades for damage and replace if necessary Do not use the generator with damaged or unbalanced blades This will cause unnecessary wear and possibly damage to the main bearings Check the fan hub assembly for tightness Check the mounting adaptor and your mounting system for tightness Check all external electrical connections for tightness and corrosion Wash down the generator with fresh clean water to remove debris and salt deposits that can build upIf you experience a problem with your Aqua4aerogen contact LVM Products to determine the nature of the problem LVMProducts will send you replacement parts and instructions needed to repair the generator In the event that the generator isreturned for repairservice you will be notified of the cost for carrying out the work and will incur the transport costs 121314TROUBLE SHOOTINGThe AQUA4GEN generator unit is designed to give many years of reliable service as it contains really only one moving partand one electronic component they are the permanent magnet rotor and a 3 phase rectifierThe only parts that can wear are the main bearing ball racesThe Aqua4aerogen wind mounting contains slip rings carbon brushes plus a panel mounted plugSIMPLE TESTA simple test to prove there is an output voltage from the Aqua4gen can be carried out whilst the Aqua4gen is in itsworking position Disconnect the Aqua4gen output cable from the battery or the TB regulator if fitted With the turn the main shaft it should turn freely Note There will always be a slight resistance felt this is the coggingeffect of the generator then touch the two output leads together shorting them the main shaft should now be noticeablymore difficult to turn If this does not happen check that your extension wire connection from the actual Aqua4gen outputcables are not corroded or have become disconnected Check inline waterproof plug for good tight electrical connectionsand possible corrosion If there is a fuse fitted in the output cable check it has not blownThe following tools and equipment will be needed to carry out tests and repairs to the Aqua4genA multimeter which can read 0 100 volts DC measure resistance have a diode test and a continuity buzzer testPozi drive iron and of hardwood and a brass rod 12mm diameter X 250mm long or similarFor pivot bearing replacement a bench vice will be OUTPUT VOLTAGEIf you have a lathe or some other means of turning the main shaft at a known RPM a 12v model produces 006v per revand a 24v model 012v per revIf no voltage is present check that your extension wire connection from the actual generators output cables are notcorroded or have become disconnected If there is a fuse fitted in the output cable check it has not blown Check outputvoltage again at the generators actual output cable If there is still no voltage output go to the instructions and tests listedunder heading NO OUTPUT VOLTAGE Wind modeWith the Aqua4aerogen in its operating position disconnect the generators output cable from the battery or the TB regulatorif fitted and attach a multimeter set on 0 100 volts dc range to the two output leadsThe following open circuit voltages should be obtained at the wind speeds shown below It is most important that the windspeed is measured

and lever out3 Remove the front 15mm circlip on the main shaft4 Remove 6 off selftapping screws retaining the rear cover5 Place a piece of hard wood on a concrete floor Holding the Aqua4gen with the rear cover held back and main shaft downwards lift and force downwards the generators main shaft onto the piece of hard wood This should displace the main shaft inwards Alternatively the main shaft can be pressed out or hammered out but take care not to bruise the end of main shaft6 The main shaft rotor assembly should now have moved inwards into the main housing7 Using a piece of brass rod or similar so as not to damage the end of the main shaft tap the shaft through both the bearings and remove rotor assembly from the rear of the main housing8 Having removed the rotor from casting Check the main shaft for wear particularly the areas the main bearings are positioned If the shaft wear is found to be excessive a new shaft will have to be fitted Contact LVM Products 9 Remove the large internal circlip which is located in front of the main outer bearing then using a brass rod and a hammer knock out the main bearings from the casting 10 Refit new main bearings using a little Loctite Bearing Fit smeared on the OD of the bearings 11 Refit large internal circlip in front of main outer bearing this circlip acts as a spacer for the water seal 12 Clean the main shaft then clean the rotor magnet with sellotape sticky side to remove small pieces of steel pickup13 Smear a little Loctite Bearing Fit onto the main shaft close to the rotor and in the bore of the outer main bearing14 Insert the main shaftrotor assembly into the generator main bearings WARNING The rotor magnets are very powerful and will quickly draw the assembly into the stator When the main shaftrotor assembly is fully inserted check it rotates without rubbing15 Smear a little Loctite Bearing Fit on the outer main bearing inner race to shaft ie between the OD of the shaft and the ID of the inner race Push the main shaft in and out a little to spread the Loctite between the outer main bearings bore and the main shaft16 Fit new 15mm circlip on main shaft17 Fit new main shaft water seal grease well on assembly18 Refit rear cover using a new gasket make sure all internal wiring is clear of the rotor 18 SELECTING THE CORRECT LVM VOLTAGE REGULATORThe output of the Aqua4aerogen in water or wind mode can be simply connected directly to the terminals of the battery thatrequires charging however if the terminal voltage of the battery is not continually monitored for over voltage 142v for 12vbatteries and 284v for 24v batteries the battery can be seriously damaged Fitting an LVM voltage regulator will protectthe battery from becoming over COMPENSATION This additional feature is available on all LVM regulators If the battery is located in abuilding where the ambient temperature is always around 20 degC then standard regulators can be used However if youintend to locate a battery where temperatures may go down to freezing and perhaps rise to tropical temperatures then youshould install a regulator that is fitted with a temperature compensation circuit This automatically allows the battery to becharged at a higher voltage as the temperature drops and a lower voltage if the temperature increases Simply add Tafter the LVM Product No ie 4TB12 TThe regulator suitable for the Aqua4aerogen Twin battery regulator LVM product No 4TB12 4TB24 These units are connected between the output of theAqua4erogen or Solargen module and the battery terminals They control the actual output voltage of Aqua4aerogen orSolargen by diverting power to a high wattage wire wound dump resistor when their output voltage reaches 142v 12vsystems or 284 24v systems They have two schottky blocking diodes built into the regulator which enables them tomonitor and control the charge to two batteries totally independent of each other therefore making it ideal for of engine starting and domestic batteries The battery with the lowest terminal voltage will be charged first thengradually when both batteries become fully charged the Aqua4aerogen or Solargen modules output is automatically divertedto the dump resistor this does two things it stops the batteries over charging and keeps the Aqua4aerogen water and windmode always on load Note This regulator draws NO standby current from the batteryAlso available from LVM Products are Diode Units LVM product No 4DU 6DUThe 4DU when combined with a 2TB or 4TB regulator enables one additional battery to be chargedThe 6DU when combined with a 4TB regulator enables two additional batteries to be chargedThe Aqua4aerogen and a Solargen modules output may often be combined the table below shows the for various systems Note Two batteries wired in parallel are classed as one independent battery Having selectedthe recommended regulator model from the table simply add the voltage required ie 4TB12 for a 12v system or 4TB24 for a24v system Basic wiring diagram are shown on page 10 If you cannot find your particular system or application within thetable or require full wiring diagrams please check our web site
