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
can be lethal.
• 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 nec-
essary that the user reads the warnings and keeps them in due consideration. Failure
to observe a danger sign or warning may harm operators or damage the machine.
Safety devices must not be removed. The structure of the appliance/equipment or their
functioning must never be modifi ed.
Field of use
(for the German market only)
According to the annex no.50 of the General Framework of the Administrative Standard
regarding the minimum requirements for conveying waste water coming from dental
surgeries to the drainage system, it is necessary to install amalgam separators to treat
such water containing amalgam.
Working
(draw. 1 page 41)
Inside the centrifugal separator air is separated from aspirated liquid, then after pass-
ing 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.
