I don't recall ever seeing any specific instructions but it's pretty straight forward, basically it's the same as the DA or RAM nozzle with 1 exception, clocking. I THINK that Bryan now sends the pins trimmed to length, if not you also have to cut the pin to the correct length. Originally he did not.
Here are the basic steps, the way I do it at least.
1. Assemble the Phoenix internals just as you would a Royal AM, you can use the Conshelf or RAM manual as a guide. A HP assembly tool is very helpful, it can be done without one but it's a huge PITA.
2. Install the diaphragm, thrust washer, spring pad, spring and spring adjuster in the main body and tighten the spring retainer. Install the spring adjuster in the spring retainer and install them as a unit. Leave the spring adjuster out as for as possible for now, installing it after the retainer is installed is a lot more difficult to do. Leave the adjuster where it is for now.
3. With the Phoenix upside down, install the pin and pin support. Make sure the pin goes in all the way and is into the HP seat. The pin should be almost flush with the Phoenix nozzle and centered in the hole, if not something is wrong. Install the pin support.
4. While holding the Phoenix upside down (pin support up), install the nozzle gasket and screw on the main body until it's hand tight. Then tighten more, I don't know of a spec on it. I do it by feel- pretty snug but don't go gorilla on it. If you have a wrench that is large enough you can use that but be careful not to over tighten it. I use 2 vise tools, one in opposite ports as handles/wrenches, they give me plenty of leverage without being too much.
5. Assemble the rest of the reg EXCEPT the cans, SLOWLY pressurize it, set the IP and inspect it for leaks and a stable IP. At this point IF
the clocking is about where I want it, I hook the reg to a pony tank and submerse it in a bucket of water to check for leaks, correct these as needed. If the clocking is not very close to where I want it, I move to step 6 and do the dunk test later.
6. Next comes clocking the Phoenix. This step is optional, if you are happy with where the ports end up and the hoses routing makes you happy, move on to step 7, otherwise read on. If the ports need to be advanced a little, simply tighten the Phoenix a little more, just do not go gorilla on it. If that does not work then you must remove the Phoenix, add an additional gasket and return to step 3. This step is a little experience and a good bit of dumb luck....and often a compromise. If you are using nylon gaskets be aware they are fairly easy to extrude out so be careful how much you tighten them past sealing.....word of experience, have a few extra gaskets on hand...not that I have ever messed up any of them.
7. Recheck the IP, repeat the dunk test, correct any problems and if all is good, finish assembling the reg.
That is how I do it.
