General Tips Section
To disassemble the chamber, remove the bottom plate over a sink to catch any water still in the chamber. Wash with a mild soap and warm water, rinse completely, and allow to dry out of direct sunlight. When reassembling, push the bottom plate back onto the chamber and ensure it is completely sealed all the way around the chamber to avoid any leaking.
