Removing Spring & Filter...
1. Remove the mouthpiece from the chamber connector.
2. Unscrew the chamber connector from the ceramic heating chamber.
3. Turn the chamber connector upside down and the mesh filter should fall out easily.
4. To remove the spring from the chamber connector hold the spring at the highest part possible. Twist counterclockwise and quickly pull it
through the smaller opening of the chamber connector.
5. The spring is very delicate. If it is stretched from original size, it should be replaced.
6. The 420 Pen® is designed to work without the spring as well.
Replacing the Spring &
Filter…
1. Place the spring, smaller end first, into the chamber connector. Gently pull through the other side until it is secure in its place.
2. Place the mesh filter inside the chamber.
3. Press the filter in firmly and evenly.
4. Screw the chamber connector to the ceramic heating chamber.
5. Insert the ceramic filter to the mouthpiece.
6. Connect the mouthpiece to the chamber connector. Make sure the mouthpiece is pushed all the way into the chamber connector. If the
mouthpiece does not go all the way down, then the mesh filter is not laying flat and needs to be readjusted.
