To Replace Coil Unit:

1) Remove EVOD from battery by turning base counter clockwise. Always remove the EVOD from battery by grasping & turning the base ONLY. If you turn the tank it will separate from the base & liquid will leak out.

2) Hold EVOD with base facing up & mouthpiece facing down. Turn base counter clockwise to remove from tank.

3) Hold assembled base & coil unit with base facing down. Remove coil unit from base by turning coil unit counter clockwise.

4) Thread replacement coil unit on to base by turning clockwise, secure snugly but do not overtighten.

5) Fill tank & replace the assembled base/coil unit to the tank and allow the liquid to soak in for about 10-20 minutes on first fill & about 2-3 minutes on subsequent refills.

6) Connect the EVOD to your battery & you're ready to go!
