REPLACING THE NOZZLE
- To change the nozzle, unplug the diffuser, remove the bottle of oil, and carefully pull out the clear tube. Gently pull out the black nozzle by wiggling it gently using a pair of tweezers.
- Replace it with a new nozzle and ensure the nozzle is pressed very firmly into the top of the diffuser. The tube can be reinserted into the nozzle. It is very important to insert the tube into the correct opening of the nozzle. There is a small round tube holder into which the tube must be firmly secured.
