Simply unscrew the mouthpiece and pull out. Hand-tighten the coil (piece with the rubber cover that sticks out the top of the clearomizer) as the coil sometimes gets unscrewed a bit when unscrewing the mouthpiece. Pour e-juice directly into the clearomizer along the inside wall slowly and the tank will fill up. Do not go above the wicks to leave a bit of space for air. Tip the clearomizer so that the wicks get saturated and the e-juice gets into the coil (about 20 seconds should be fine). Attach the clearomizer to the battery by turning slowly from the base end of the clearomizer so as not to break any seals and only tighten enough to make the connection. If you press the battery button and it doesn’t work, then tighten a bit more. The reason for this is that you do not want to force the clearomizer too tightly as this may cause the post in the battery to get pushed down whereby no connection may result. If this happens, usually a 510-Ego adapter can be used to fix this issue. Before vaping, give the clearomizer a quick tip so the fluid goes to the top of the clearomizer as it needs to run through the side holes located under the white rubber piece near the top in order to keep the wick wet. If you don’t do this then you will get a burnt taste. The CC clearomizers come with 1.8 ohm coils. When a coil burns out we offer replacement coils for sale on our website. Replacement coils are available in ranges of 1.5 – 2.5 ohms. (1.5 - 2.2 ohm are mainly for regular Ego style batteries, while 2.2 – 2.5 ohms are for higher voltage units, example Ego-C twist, Ego-T2 Upgrade, Ego-T Mod, I-Taste, Lavatube, Lambo, Provari) To refill a clearomizer, tighten the coil before filling. Sometimes the coil will unscrew somewhat when the mouthpiece cap is removed. To clean a clearomizer, simply unscrew the mouthpiece and coil, then wash all 3 parts under warm tap water. Be sure to dry the wicks with a tissue or cloth and be sure to blow out any water from the coil tube and clearomizer tube. It’s best if you can clean them at night and dry overnight.
