Actions: Clean the condensation and residual liquid regularly with a clean dry cloth.
Tips: If the device is kept standing still for long period of time (e.g. over the weekend), or you have already vaped it for several days; residual liquid or condensation may accumulate under the tank.
When you tilt the device, this residual liquid or condensation may flow out from the air intake holes or connection part if the tank is not screwed well.
If the tank is not screwed tight on the battery unit, the residual/condensation may leak out from the tank/battery junction also.
