Uwell - Crown IV (4) Coil | Major Vapour
Uwell Crown 4 Coils are vertically orientated parallel coils with organic cotton made for the Crown 4 Sub-Ohm Tank system. The Crown 4 Replacement Coils come in a pack of four.
**NOTE** Always “prime” coil before use. We recommend filling the tank and letting it sit for 5-10 minutes before use. Failing to do so, will result in a burnt coil. Burnt coil should then be replaced. Thoroughly dismantle, clean, and inspect all tank components for wear, faults or replacement of rubber O-rings and or seals. Failure to do so may cause the newly installed coil head to not work correctly and may even damage prevent further use. Do not attempt to clean used coil heads with water, this will lead to the coil wire rusting and should be strongly avoided.
