Single-surgery ISO Hydrocyclone

The single-surgery ISO Hydrocyclone is an amalgam separator for air systems with
air-water separator in the dental unit. The single-surgery ISO Hydrocyclone unit shall be
placed at the bottom and on the left of the chair.
The spittoon rinsing shall be timed for a maximum of 20 seconds. The liquid arriving from
the spittoon and from the air-water separator enters the fi lter (A), through the pipe (B)
gets pump (D) which pushes the liquid into the ISO Hydrocyclone (I) that separates the
amalgam and drains the liquid into waste through the pipe (E). To replace the amalgam
container (F), (see "General recommendations and biologic hazard") open the tap (G),
remove the cover (H) to drain the liquid contained in the ISO Hydrocyclone (I) and in the
amalgam container (F), then follow the instructions given on page 16. Any air bubble, which
can impair the pump operation (D), will be expelled by electrovalve (C).

The advantages of centrifugal separation within the dental unit

(fi g. 19-20 pag. 63-64)
The advantages of centrifugal separation in the dental unit, compared to traditional systems
with Mini-Separators, are numerous and doubtless much-appreciated by members of the
dental profession:
1 - it avoids level-checks and stoppages in the aspiration due to foam,
2 - it permits the application of the Hydrocyclone and simplifies maintenance
procedures;
3 - furthermore, the separation of liquids directly on the dentist's equipment permits the
installation of a system with countersloping piping, (or with siphons, which are insuperable
with wet equipment).
For more information, see our manual "The centrifugal separator in the dental
unit".

Maintenance and periodical checks reserved to authorised engineers

(fi g. 2-6 pag. 52-55)
• Electrical shock risk: even 230 V power can be lethal.
• Biological danger, danger of infections from epidemic diseases.
• Compulsory direction of fl ow and rotation sense.
Test photodiodes operation (detail 22 page 52) by inserting a metal object between the
two photodiodes. Ensure lights are working.
Short-circuit sensors and check:
- aspiration system stop in the single-surgery units;
- closure of electro-pneumatic valve in multi-surgery units;
- starting of draining pump for both units.
Remove the lid (detail D page 55) pull out the draining pump, or the centrifugal separator,
ensure it is working and clean the area before replacing it. Carry out operation tests of
the printed board, tracks, relays and any part that is subject to wear and tear.
For every replacement use original spare parts. Check the condition of pipes carrying
aspirated liquids, in particular the part between the draining pump (or the centrifugal
separator) and the Hydrocyclone (detail 3 page 55). In case of cracks, however small,
pipes should be replaced.
Make sure that staff in charge of cleaning and sanitising the aspirator remember their tasks
and that they use the recommended products and procedures. It is the responsibility
of the technician in charge of general maintenance to instruct surgery staff as to the
daily maintenance routines required.
