Water quality
Lime deposits and corrosion residues in tap water can lead
to the following malfunctions:
•
Premature clogging of the filters in the unit
•
Rapid clogging of the fine water paths and jets in the
treatment instruments
For these reasons, the following points must be observed:
•
If the water hardness exceeds 12° dH (=2.15mmol), in-
stall a water softener.
•
Set dilution hardness to 8° dH (1.43mmol).
•
Install a conventional fine filter.
Fineness: >80µm (0.08mm).
•
Installation must be performed in compliance with the
recommendations of the national installation require-
ments (e.g. EN1717/DIN 1988).
•
The water quality must comply with the national re-
quirements for drinking water.
•
The connection must be made to cold water.
Air quality
Oil-free, dry and hygienically perfect air is required for driv-
ing the highspeed handpiece, for cooling the burr drives
and for the cooling spray.
