Just some notes on what works best for me with these two devices in combination.
Although the Vivi Nova can be laid down horizontally without leaking due to the good seal, it will flood the atty. It works much better when you keep it vertical and keep the juice below the top of the wicks.
If there are issues with vapor production, remove the tank from the battery, remove the top, and remove the silicon seal and look down into the atty. Use a q-tip or other pointy stick type device to make sure the cylindrical wrapper that goes around the coil to protect it from shorts is centered well. There is a rim that the silicon seal sits on. Make sure that rim and the rest of the area that will contact the silicon is dry. Wipe out the inside of the seal as well before replacing it. Make sure the metal bushing inside the seal is sitting so that the flat side is down onto the metal rim on the atty. Also, make sure the atty head is actually screwed in tightly. Before replacing the top, make sure that bushing is fully seated against the rim. Use a q-tip or similar to push it down if it isn't. When screwing the top back on, don't tighten completely, just sort of tighten it but not too tight. The same goes for screwing the tank back on to the battery. Tight, but not really tight. This seems to help airflow some, and probably will extend the life of the 510 connection. After you get it back together, if the situation hasn't improved, remove the drip tip and make sure the silicon seal is seated centered. You should be able to tell by looking into the hole. If not, fiddle it around until it is.
If you're getting some juice in the works, remove the whole tank and blow down into the drop tip with a paper towel wrapped round the bottom to blow out any juice that might be caught inside. I've never had any come out though when doing this, so I'm not sure if this is a common issue or not.
1.8 ohm heads on a fresh battery works most of the time, at around 4.18 volts, but it can be a bit hot for some juices I think.
When refilling the tank, pour the juice in over the wicks so they are primed well.
The whole setup seems to wick pretty well, but I would recommend at least 30 second to 60 second breaks between hits. Slow drags, 4-5 seconds at most usually. I wouldn't burnt it more than that with a 1.8 ohm or it won't keep up.
There is a lot of info about cleaning and rebuilding the Vivi Nova 2.5 in the forums. My process is to take the tank assembly apart completely. Be careful with the head and wick if you intend to reuse it, as the wick will break and fall apart if you handle it roughly. I soak everything in everclear, swish it around, then soak the head and wick assembly separately and swich it around gently. Let everything dry, and blow out any residual liquid. Once it is all dry, put the head back on the bottom of the tank, but don't bother with the plastic part or the top and tip yet. Check the resistance with a multimeter with negative on the outside of the bottom connection, and positive no the center of the bottom connection. It should be very close to 1.8 ohms, or whatever resistance head you are using. Put the head and bottom back on the battery, and dry burn until it glows red. Take it back apart, and put the head only back in the everclear, swishing around again to knock loose any remaining residue. Dry it off again, and put the whole thing back together. Recheck the resistance, fill it with juice but no further than just below the top of the wicks, and let it sit for about 5 minutes (standing vertically). Give it a little dry pull with no power, then hit the power and do a 3 second vape. One or two more of these 30 seconds apart and you should be good to go.
If you need a lanyard for the bolt, you can do what I do, and use some paracord. Take maybe 5 feet or so, can't remember the length. Fold the cord in half, and use a prusik knot to hold on to the bolt. At the loose ends, tie a good old square knot and melt the ends. The prusik knot will hold tight to the bolt as long as you pick it up by the cord always. The downside is the knot will slip right off the bolt if you don't pick it up by the cord, or grab on to the knot when picking up the bolt top vape. If it does, it usually retains its shape, and you can slip it back on. you can also just rewrap it easily, since it's an easy knot to make. Great for just dropping around your neck. It should never slip off when used properly. I like to also tie a square knot in the two cords just above where the prusik loop sits, to keep it from slipping too loose. Basically once you have the prusik pulled tight around the bolt, hold the prusik loop tight, and make a square knot with the rest of the loose cord, pulling the square knot tight just shy of where the loop of the prusik lays naturally when it is tight. Not too close, but not too far away either. I use a two wrap prusik. Anything more would be ludicrous.
Here's a prusik in its normal use around another rope.
