Step 1
Remove service cap only from refill vial. Make sure collar is NOT removed and screwed on tight.

Step 2
Screw service cap onto empty vial in PerfumeAlum™ base and pull out empty vial.

Step 3
Insert refill vial (again make sure collar is tight) and when it hits the PerfumeAlum™ base turn clockwise until it snaps into place. You will hear a "click" sound.

Step 4
Should the refill vial not click in correctly, remove vial using service cap and try again.
