Observe the following:
● Change the water at least once a week.
● With ambient temperatures above 25°C, change the water every 2 to 3
days to prevent foul odors.
● Drain the tank if you do not intend to operate the unit for more than one
week.
● Clean the tank if the odors recur.
● Add DENTATEC milling additive and fill the tank up to the brim with water.
Let it stand for at least 24 hours and then rinse it out thoroughly with water
once again.
CAUTION
Damage to surfaces!
DENTATEC milling additive etches plastic surfaces in undiluted form and
can cause discoloration.
