• Introduction
The following presentation is intended to illustrate the equipment and the appliance in order to
clarify their working and maintenance. It also informs users and technicians of possible dangers
and about the precautions to be taken for accident prevention.
• Signals and warnings
• Electrical shock risk : also 230 V
• Biological danger, risk of infections from epidemic diseases.
• General danger sign.
• High temperature.
• Compulsory direction of fl ow or of rotation.
Signs cannot fully express danger warnings and compulsory notices, therefore it is necessary
that the user reads the warnings and keeps them in due consideration. Failure to observe a dan-
ger sign or warning may harm operators or damage the machine.
Safety devices must not be removed. The structure of the appliance/equipment or their function-
ing must never be modifi ed.
• Field of use (only for the German market)
According to the annex no.50 of the General Framework of the Administrative Standard regar-
ding the minimum requirements for conveying waste water coming from dental surgeries to the
drain age system, it is necessary to install amalgam separators to treat such water containing
amalgam.
• Working (draw. 1 page 40)
Inside the centrifugal separator air is separated from aspirated liquid, then after passing through
the inlet passage (1) the aspirated liquid reaches the evenly spaced holes (2) which spread the
fl uid uniformly inside the cone and give it a rotary descending motion.
When the fl uid reaches the bottom of the cone (4), inversion of the fl ow rotation and direction
takes place; at that moment of zero speed amalgam particles fall into the bottom of the container
(5), whereas the liquid rises out of the middle of the cone.
The re-circulation valves 6 and 7 open and close the passage for the drainage of the amalgam
depurated liquids.
During the phase A the system has not reached the fi xed fl ow, therefore the liquid is conveyed
back to the Hydrocyclone; in the phase B, with the suitable fl ow, separation is obtained and the
processed liquid can be conveyed to the waste (8).
