    Dolphin Injector cleaning

    Hi, does any one know how to clean the injector of the dolphin? In Portugal there is no one to do this maintenance, and I've got the 50% with problems.
    Regards

    You don't clean them you replace them... Unless you are positive its just a salt deposit from some water entry than can be dissolved, assume its other problems..

    You also have to look at WHY you have a problem so it doen't happen in the future..

    I know they use a laser drilled ruby for the orifice, would a few minutes in an ultrasonic cleaner do them any harm, ... If there's reason to suspect it's just some salt deposits?

    It is salt deposit. he worked fine for near 25 dives and then decresed the flow.
    I've contact Drager because the 50% and the 60% injector always had a flow smaler than the standard. They say its normal.

    Remove the ruby using a flat head screw driver and soak it in a little vinegar, or just toss the entire injector into the ultrasonic cleaner. I have used both methods and have not had any issues.

    They are in the manual, which is available online. Google it, if you can't find it send me a PM with your e-mail and I'll send you a copy.

    Becareful with the ultrasonic cleaner for prolonged periods. I had a jet that was well out of spec and we tried cleaning it with fresh water soaking and then Vinegar and then short bouts of the unltrasonic bath with simple green and it got better but still too far out of spec. (low flow)
    We said well what the heck, "it is now good as is, and we will probably have to buy another any way, so lets give it over night".
    Well it was still out of spec in the morning, just the other way. (too much flow)

    It wasn't a total loss because that was the jet, once I removed the ruby, that I use to add diluent through manually. Silver lining I guess.

    Hope that helps.
