Does anyone do a Meg trimix manual?

Out of interest, Joe, why did you choose to leave out descriptions of how to calibrate and do positive and negative tests?

I guess the pos and neg could be added, there really wasnt a reason other than its easier to be shown than to have BS description added in the text..

as to the calibration.. I do not see eye to eye with leon so it was better not to put something in print that either he would not like or that I do not believe in..

If every 50 hours I have to pull apart the solenoid then I, as an owner, need to know how to do it.

Call ISC. Ask if where the nearest Meg Tech is. Send it to them. Otherwise, go to ISC and take the Tech course. They will teach you how to do it and certificate you to do so. This is no different than tearing apart your Apeks regs from that standpoint. They want you to be a certified tech for legality reasons. While you can find black market Apeks service manuals on the web, I haven't seen any black market Meg service manuals yet. For those that are gifted in the ways of all mechanical, they are probably able to do so without the manual.

If every 30 hours I am going to have to change batteries then I need to be able to do it myself, but no manual advises you on that. Those batteries are a pain to get hold of and expensive to freight, so I need to know how to change the wiring or make my own batteries.

If I can figure out how to remove two screws and plug in a new battery, anyone can. No need for a manual on that. As for rewiring the battery box to accept DIY battery kits, that's not something the factory is going to probably condone. They would have no control over your level of knowledge or skill, and the possibility of frying the electronics is real. I doubt a training agency is going to start teaching DIY tricks either. Your best bet is to read the posts on the Meg Users Forum to get the insight as to how to do this.

It seems very wrong that every owner should be faced with a choice of taking a technician's course in the US or being unable to dive his unit for a significant part of the year while it's back at the factory getting basic work done on it. These days, you get a War & Peace-sized manual with a toaster oven, and you don't trust your life to a toaster oven. ISC need to get to work on a manual.

My toaster didn't come with a manual. If I needed one to use it, I probably shouldn't be allowed out in public without a helmet and knee pads. There are people that are certified techs that are probably closer to you and can service your unit quicker than ISC. Call ISC and find out. If you send your head unit to ISC, it won't be out of service for a 'significant' part of the year. When my regulators need overhauled, I send them to an Apeks shop and wait 1 to 2 weeks. What's the difference with your solenoid?

thanks kieran, moray & joe.. i used lindas e-mail everytime, but i will give ian a buzz in the morning

it will be good to have it and to read it over & over on the plane back to OZ in a few weeks

thanks again

Battery info is attached, your instructor should have given you a copy of this or sent you the link, but we all do forget things at times.

DO NOT rewire the battery compartment leads, obtain the correct molex plug and do all your wiring on the battery pack side.

I did a photo essay of the DSV rebuild Megalodon DSV Rebuild

Your instructor should have covered calibration at least 5 times during your course, contact your instructor for a refresher. If you have not been trained, I am available to give you a proper course.

As for the mixed gas manual, there is none specific to the meg as the information for moving to mixed gasses is common to all CCR's. IANTD has a CCR tech manual that is pretty good, but you will still need an instructor to bring it all together for you and drill you on the skills. I dont provide manuals unless you are my student, same as Steve. There is a LOT about meg training that is not in the manual, attitude, skill practice, bailout procedures, how to preform the pre dive checklist properly. The manual is a reference and companion to the course only, it does not provide all a diver needs to dive the Meg safely.

It all depends what you call significant: if you are diving every weekend then missing a few weekends in a row is a long time; if you're not , it's not. FedEx is very inefficient in Japan and takes a very long time; it might be faster if I lived in Florida like you. My Meg now takes off-the-shelf lithium batteries: thank God a friend was on hand to re-wire it, because I wouldn't have known and there was no manual I had on hand to help. I'm sorted: other people might not be.

Thanks for the DSV link: very nicely explained.
My point about the calibration was not that I can't do it but that it was an example of an important skill not covered in the manual. Joe's comment that he didn't include it because he couldn't agree with the Leon on how it should be done seems especially interesting. I've been taught 3 ways: I use the method that uses least O2.
The ANDI manual is nicely written, and I read it cover to cover on the evening it arrived. Most manuals aren't like that: the manual I got with my mobile 'phone was huge. I wouldn't dream of reading it, but I know that because it is comprehensive I can find the answer to pretty much any question in there (the number of features on Japanese cellphones is incredible).

I do not believe I can praise the ANDI manual enough.

Even after 25 hours I am still referring to it again and again.

But like all good documentation, it needs to be reviewed and updated.

It maybe a good idea to show the various methods of calibration and explain the Pros and Cons.

My Trainer (Steve), I cannot praise him enough as well, showed me 2 methods of calibration and I use both depending where I am and what I am doing.

As more Megs are coming on line, the questions on Self-Servicing will come more frequently.

I have turned the stone on the Batteries and my Trainer did supply with batteries and I see from that initial interaction how they are made up and now I am getting some made up myself through our Battery World franchise. I will be looking at both the Alkaline and Lithium options, I am supplying the manufacturer with the documentation from the ANDI manual and the ISC pdf.

I am now turning the stone on the Solenoid issue, one response was to change the solenoid over with a new one, an option I am willing to explore if the price is right, but if I am in the middle of nowhere it would be good to know how to repair things and what items to have in your toolkit and spares, if it possible through a manual.

I am quite isolated in Sydney in the moment being in amongst all the Inspos, as I am the only Meg in Diver in Sydney and it will be good to know how do things on my own for my own piece mind.

Other options are when a year or 18 months is up is to get the Head Serviced by ISC by upgrading the head to the latest version.

And praises to Rebreather World as well for minimising my isolation

Thats what I reckon - upgrade and service the head with ISC at the appropriate juncture. With me it'll be after maybe 9 months of diving, but it'll be after over 50 hours personally on the unit and I feel the head needs to be serviced and updated. Will service the regs locally at the same time since I won't be able to dive the darned thing anyway.

Could you give a real quick description of the 3rd method ?

I am aware of:

Using ISC calibration adapter at the center tube (or better yet, using skipbreather's adapter)
Manually flush the loop 3-5 times with O2.

Just trying to learn... Thank!
