Paragon Service manual or likewise

Håkan K

When I some time ago did a dive with my Classic Kiss the Paragon second stage regulator started freeflowing. Nothing I did could stop this. It seems as if the seat has become to deformed to seal. I had the Paragon disassembled, but would like to have either a service manual for the Paragon or some pictures of how it is assembled. Anyone out there that has the information?

Thanks in advance.

The seat gets "cookie" cut by the valve, you can sometimes delay the inevertible by flipping the seat but your best off canning the whole crap-fest and fitting the Mares kit, another BOV or a straight through DSV (In my very humble opinion)

I believe the Paragon is a Mica reg (shared internals) no LDS I've ever spoken to was able to do anything for it and its a PITA to strip and reassemble.

From the KISS list from some time ago:

1 Remove outer screw.
2 Lift off knob.
3 Unscrew the retaining collar with a spanner - note the thin O-ring underneath and the groove for it.
4. Unscrew the bladed "follower" in the threaded tube with needle-nose pliers - noting approximately its depth before you do (not critical, but it is a bit easier later if you do). This part is the main cause of the problems, in all probability.
5 Clean, grease and return the follower to roughly its former position - do not tighten it into place.
6. While we are at it - there is an O-ring at the other end of the metal valve body tube (connection end). A little finger-pressure will ease this out so that the O-ring can be cleaned if nec. and greased. Return to seat, noting the orientation of the valve lever inside the body (if you have the diaphragm off - which is not necessary. IF you do, do NOT get silicone grease on the diaphragm, which is also silicone.). This is easy - big rotation steps only.
7 Back to the retaining collar from 3: push out the driver.
8 Remove, clean and grease the O-ring and seat on the driver; return O-ring.
9 Insert driver into cleaned and greased retaining ring (correct orientation)
10 Grease and return the thin O-ring to the seat around the threaded collar.
11 Return retaining ring (greased) to threaded collar, noting engagement of driver with follower. Do not overtighten, but ensure just more than finger tight (with the spanner) so it does not come undone accidentally.
12 Replace knob, noting the keyway engagement
13 Grease the thread and replace the screw.
14 Exercise the adjustment fully in and out a few times: it should now run free and the resistance at the ends of travel obvious.
15 Check that it breathes properly when on minimum (in) and throws air at you when fully open (even with the valve seat proper detuned as discussed elsewhere).

And an exploded diagram of the parts for you (I don't have the names to put to the numbers).

Process for dealing with the "Paragon of Unreliability":

I had mine 'cookie cutter' the seats (have two of the BOV's), got new seats from Kim, and still could never get them to stop freefowing. Finally, I developed a plan that worked for me and suggest you follow it:

(1) Remove from BOV in the usual way.

(2) Using tie-wraps or other suitable device (wire, string, etc), attach a heavy but cheap steel or concrete weight to it.

(3) Take a ferry ride and someplace about mid-voyage, toss it off and feel lots better. As it sinks, look for the last bubbles to escape it, and smile knowing that they are the LAST ****ing bubbles ever to escape the damned thing.

(4) Buy the Mares adapter kit, install the Proton second stage, and enjoy life.


Utter junk worthless cheap unreliable crap Chinese POS.

(I feel better now...)

I found good instructions for servicing my Paragon here on Rebreatherworld.

Here is the thread.

Works a treat.

Thanks all for the help.

However, could someone that has done the conversion publish some photos? Would be very interesting to see how the DSV looks with a Mares second stage.

I did a step by step here: Converting to Mares BOV

To be honest, after using the Mares for a few months I haven't found it massively improved. The exhaust valve is shite, you need to be really careful to check that it is sealed at the start of the dive otherwise it can sit away from the body and wet breathe if you haven't done a few test breaths to suck it into place. It's also absolutely massive as well, it sticks out a mile. I think Jetsam really needs to give some attention to the design of the DSV, it breathes fine, I've bailed to it at 60m but it is just all feels a bit jury-rigged as a solution. It doesn't feel "designed", it feels like someone has stuck a 2nd stage on the front of the DSV, I'd have thought the size of Jetsam now they'd have built something a bit more integrated.

Cheers,

Stuart

Stuart I think I know what you mean. I have a jax moutpiece that gives a lot more stability to the heavy protruding stuff hanging from it. It is expensive for a mouthpiece (some 25 euro) but mine is in use for two years now and there's no visible deterioration.

Hi Stuart,

"Really" on all of the above? I agree that it's a little "long", but in a year I've not had the other issues you describe. I'll go re-investigate, but there';s no wiggle or leak potential that I've experienced. Hmmm..... time to go poke at it again.

Agreed on the fact that it's time for them to re-engineer a modern BOV though. A smaller version of the Golem layout (copied from the CIS, actually) would make a lot of sense.


Dutchy: I also use a Jax, and it does make a huge difference.
