To avoid leakages of e-liquid into your mouth piece or into the middle tube of the tank, make sure you refill the Uwell Crown 3 subohm tank using a needle point bottle or refill kit or a glass dripper.
Please be aware if you overfill or don’t refill your Uwell Crown 3 subohm tank properly (Top fill), you might draw some eliquids to your mouth every time you vape, or your vaping experience might be disturbed by a gurgling sound caused by the excess of eliquid inside the middle tube of the tank.
Uwell Crown 3 subohm tank and coils have a resistance which is under 1.0ohm. Sub ohm atomisers/coils tend to be bigger, as a result, it can utilise more power, eliquid and cover a greater area of wick. This combination results in massive vapour production.
High-powered device paired is required for sub-ohm vaping (a separate high-drain battery may be required - e.g. the Efest 18650 battery or rillipower 26650).
"Direct-to-lung" is the suggested vaping style for sub ohm devices (as opposed to "mouth-to-lung" - i.e. how a traditional cigarette would be smoked).
When using sub-ohms tank like the Uwell Crown 3 subohm tank, its highly recommended to use Subohm eliquids with PG/VG: 20/80 or higher VG% and if using nicotine eliquids, it must be under 6mg, otherwise you will feel it peppery/harsh on your throat when vaping.
Priming tips: Whenever you install a new coil you will want to make sure you prime it before using it. Priming a coil will ensure that the wick is fully saturated with e-juice prior to its first use. This would substantially lower down the risk of burning the wick or damaging the coil. Check instruction before use.
Steps to prime your coils: Add 4-5 drops of e-liquid directly into the coil head, close the airflow switch, then refill the tank as per instructions. Prior to attaching the tank to the battery/MOD lightly suck air through the mouthpiece about 5 times. Make sure the airflow switch located at the bottom of the tank is closed before refilling it with e-liquid. If the airflow switch is left open, the tank will leak eliquid while priming the coils.
Open the airflow soon after priming, wait 3 – 5 minutes then vape.
