JOMO Tech Royal 30 Replacement Coils
DewEach of the Royal models have their own specific coil : their coils won't work in any other e-cig and there are no other coils that will work in the Royal models.
Both models have the same style of All-In-One Tank, with the coil screwing directly into the base of the Tank. This design makes the Royal models probably the easiest e-cigs going when it comes to filling and replacing coils : it's even the same process, whether you're changing the coil or filling the Tank . . . well, not entirely the same process as such, because in one case you're removing the coil and in the other you're not, but it's the same start and end processes if you want to get technical about it.
To replace the coil in either Royal model, take a firm grip of the Glass Tank, unscrew and remove the Top Cap and Mouthpiece Assembly.
Unscrew and remove the spent coil.
Prime a new coil and screw it in to place. Take care not to cross thread the coil as you screw it in and make sure it's secure and tightly screwed in. There's no need to go all Incredible Hulk on it, just make sure it's tight.
It's good to get into the habit of checking the coil every time you remove the Top Cap and Mouthpiece Assembly. If you're ever going to have any problems with your e-cig, I can almost guarantee that it will be something to do with the coil.
Priming coils is necessary in the new generation of e-cigs simply because most contain a fairly large piece of Organic Cotton which must be totally soaked before you can use your e-cig. If you don't allow the Organic Cotton to get fully wet before use, you'll most likely burn the coil out in a matter of seconds . . . Organic Cotton isn't meant to have heat applied to it while it's dry . . . this is also the reason why you never ever dry fire an Organic Cotton Coil.
So take a look at the coil : you'll see 4 holes toward the bottom end of the coil, spaced evenly around the body, and you can also see the white Organic Cotton through the holes. Put 2 - 3 drops of liquid into the holes [you'll see it disappear pretty much instantly as the Organic Cotton sucks it up].
Once the coil is primed, you can then screw it into place and fill the Tank.
You need to let the e-cig stand for a few minutes to allow the Organic Cotton to become totally soaked with liquid.
When the coil is ready for use, you'll see that the liquid level in the Tank has gone down. Make sure that the liquid level completely covers the holes in the side of the coil at the very least, however, it's probably best practice to top the Tank up at this point.
Available for purchase as a single coil or in a pack of 5.
Important Bits You Need To Remember About The Coils
[Pay attention now, this stuff is really important, seriously]
* NEVER dry fire these coils. If you hit the fire button when the coil isn't immersed in liquid, you'll just burn it out, pretty much instantly : it only takes a couple of seconds to burn when it's completely dry and just as a side note, it absolutely reeks when it burns and the smell hangs around for a while too . . . nasty . . .
* NEVER let the liquid level in the Tank fall below the round holes in the sides of the coil [the priming holes if you like]. If the liquid level does fall below the holes, the Organic Cotton inside the coil will begin to dry out. Do not use the unit until you've refilled the Tank and the coil is totally immersed in liquid again. Best practice is to never let the Tank liquid level fall below 1/4 of a Tank.
* Prime each new coil and let the unit stand for a few minutes after filling to ensure that all of the Organic Cotton inside the coil body becomes completely wet. You may notice that the liquid level will go down fairly dramatically when you put in a new coil : remember to make sure that once the coil is fully wet, there is still enough liquid in the Tank to completely cover the coil or more specifically, the priming holes at the very least.
* Best practice is to use a cloth or tissue to remove the spent coil, they're best not grabbed bare handed cause it'll be covered in liquid and you don't want to get liquid on your hands if you can help it. You can also go for tweezers or pliers to remove the coils and when you put the new coil in, you can tighten it with the tweezers or pliers but take care not to damage the coil or over tighten it.
If you are going to remove and replace the coil by hand only, be aware that the top of the coil can be sharp [because of the thread cut into it, there can be a sharp point where the thread starts], so take care not to cut yourself. Remember girls and boys, "Saftey First" . . .
* It is recommended that the coils be replaced every 2 - 3 weeks, however, JOMO Tech goes further to suggest that the coils be cleaned in warm water, not boiling, weekly if the user is a very heavy vaper.
If you go with the bathing the coil ritual, it is suggested that you can extend the coil life in excess of a month or so.
PLEASE NOTE : If you do go with the bathing ritual, the coils must be completely dry before you return them to use and washed coils will need to be primed again before being used.
Just as a side note and a bit of a Captain Obvious moment, but make sure you dispose of spent coils by wrapping them up or sealing them in a plastic bag so that any excess liquid will not contaminate your bin.
And here's the second Captain Obvious point : don't leave spent coils anywhere children or pets can access them.
