Keeping your equipment working like new, these heater covers will help aid in an unmatched vaping experience. To replace your heater cover, remove the four rubber feet from the base of the Extreme Q Vaporizer. This will allow you to see four metal screws, then unfasten the screws and remove the bottom care entirely. Next locate the two screws on both sides of the circuit board, unfasten the screws to remove the vaporizer’s cylinder and when the its removed you will see the ceramic heater. Then take off the long cotter pin attached to the glass heater cover. Once the unit is clean, insert the Extreme Q Vaporizer Heater Cover Old Version and secure it with the long cotter pin. Once the Extreme Q Vaporizer Heater Cover Old Version is attached the unit will perform just as new. If you need a quality, durable heater cover look no further than the Extreme Q Vaporizer Heater Cover Old Version by Arizer.
