A Glade Plug-In is a scented oil warmer that plugs into a standard electrical outlet. When the oil runs out in the container, it can be replaced with a new scented oil container. An empty oil container will not be effective at providing fragrance to the room it which it is installed. Setting the fragrance level dial to a lower setting will allow the oil container to last longer.
Unplug the unit from the wall outlet.
Grasp the scented oil bottle with one hand. Grasp the top of the unit with the other hand. Firmly pull the oil bottle away from the unit.
Unscrew and remove the cap from the new oil refill container.
Insert the refill container into the warmer unit. Make sure the shell-shaped logo faces forward. Press the bottle from the bottom until it is fully inserted; you should hear a click when it is inserted correctly.
Adjust the fragrance level tab on the front or back (depending on model) of the warmer if desired. Plug the unit into an electrical outlet.
