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.
Suction pipe
Install steam trap K.
With a vacuum of pu >0.18 bar back pressure, the treat-
ment center must be retrofitted with the “Vacuum limiter”
retrofit kit (Order No.: 59 68 826).
