CLEANING
DAILY
We recommend cleaning the vaporizer daily by wiping all surfaces dry using a
paper towel or soft sponge. It is normal for mineral deposits to collect at the
bottom of the Base. Deposits may appear as black flecks and should be rinsed
out after every use.
WEEKLY
The vaporizer should also be cleaned once a week, according to the instruc-
tions listed below.
Cleaning involves two steps SCALE REMOVAL and DISINFECTING. Be sure to
perform these in the proper order to avoid harmful chemical interactions.
Unplug the vaporizer. Wait at least 10 minutes for the unit to cool.
Remove the Steam Assembly and set aside.
Discard any remaining water from the Base.
Clean all outside surfaces with a dry, soft cloth. DO NOT USE WATER. THIS
MAY DAMAGE THE VAPORIZER OR CAUSE ELECTRIC SHOCK.
