Page 2: The Physics Of Wind Generation
The DuoGen is different. By deploying the water mode when you go cruising: The DuoGen taps into the wind power that the yacht’s whole sail area intercepts This is many times greater than that of a yacht-sized turbine At typical cruising speeds, the DuoGen in water mode produces enough power to run most if not all of the yacht’s electrics... -

Page 4: Mounting Options
The DuoGen should be placed either on or as close to the yacht’s centre line as possible. This minimises the effects of heeling on the running depth of the water mode. However, in practice, if the mounting is within 800 - 900 mm of the yacht’s centre line, the DuoGen will perform well. -

DuoGen in Water Mode Adjusting the diving plane The angle of attack of the DuoGen’s diving plane is adjustable by a few degrees either side of 0º or hydrodynamic neutral. The neutral point is found by aligning the mark on the diving plane and water impeller bracket. - Page 7 The shunt is most usually connected in the negative line.

- Page 11 The turbine will begin to run. NOTE: DuoGen should always be stopped using the moulded yaw arm handle, even where an electrical brake switch is fitted.
- Page 12 This can be viewed as analogous to a yacht heeling to gusts of wind. In light breezes, the DuoGen’s air rotor will point almost directly at the wind. As the wind speed increases, it will begin to furl about the main tower pointing progressively off the wind.

- Page 16 Ensure that the cable runs freely and without obstructions. Should the DuoGen be vibrating or unduly noisy in operation, it should be stopped immediately whilst the cause is identified. DuoGen should never be allowed to run with damaged, cracked or misaligned turbine or impeller blades.

Page 18: Regulation
For this reason, where possible, a single regulator should be used. The regulator usually supplied with the DuoGen is rated at 40 amps (12 V) or 20 amps (24 V). As well as the DuoGen, the regulator will also accept the input of up to 150 watts of solar panel. -

- check that the electrical connections are secure and well made, and that the cable exiting the alternator does not snag or pull as the DuoGen moves from one mode to another - check that the line fuse has been replaced in the fuse holder With the yaw arm in its raised position and the airblades fitted (tied off with a piece of line to prevent rotation), turn the arm through 360º... -

40 – 50 hours of operation before mechanical friction falls to its design level. As a result, your DuoGen may seem a little slow to respond in light winds until this ‘running in’ period has passed. -

Read all the instructions carefully before commencing installation and familiarise yourself with the components. 2. Allow yourself plenty of time, at least four hours. Fitting DuoGen is not difficult, but it is unfamiliar, and rushing doesn't help! If you can enlist an assistant the job will be much easier.
- Page 23 M6 stainless steel nuts and bolts. As drilled holes are permanent, it is a good idea to secure the bracket using the rail clamp and temporarily mount DuoGen. Once you are confident that all is correct, the holes can be marked and drilled.
- Page 24 Take care to re-fit the rubber anti-rattle ring. 19. Enlist an assistant to help in mounting DuoGen using the short 10 mm pins, passing them through the bushes in the yoke. The machine is quite heavy and the holes need to be accurately aligned for the pins to slide home.
- Page 25 27. Decide where to bring the cable into the yacht and fit a deck gland. (Do not use deck plugs and socket.) Allow a reasonable loop of cable so that the cable is not strained as DuoGen pivots between modes. Raise and lower the machine to make sure the cable runs free.
