General information

NOTE
Damage to the pump and drives!
Too high a proportion of ceramic in the cooling water will damage the
pump and the drives.
Change the water regularly!
When the water is due to be changed, a message window appears on
your monitor to remind you that it is time to change the water.
Preventing odors
All coolant additives contain a biodegradable preservative. Despite this,
however, odors may still develop under unfavorable conditions.
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 the coolant additive DENTATEC 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.
NOTE
Damage to surfaces!
In the undiluted state, the coolant additive DENTATEC disintegrates
plastic surfaces and can cause discoloration.
➢ Do not place DENTATEC on the unit.
➢ Do not spill DENTATEC.
NOTE
Approved coolant additive
Use only DENTATEC as a coolant additive.
