units and on the electrical diagrams jointed to control panels; furthermore the feeding line
must be fitted with an high-sensitivity differential switch. Starting from the control

panel a low tension three-cores cable of 1.5 mm (section increases with distance) gets all
the surgeries connected to the same plant, D.
This line controls the switching on and off of the aspiration from each surgery in the system.
It is also advisable to install protections on the electric power distribution lines in order to
prevent demage due to overvoltage conditions. Such protections reduce the effects
caused by atmospheric fields (thunderstorms) and electrostatic charges, with a view to
safeguard electronic cards, capacitors and other overvoltage-sensitive components.

INSTALLATION

The dental unit is almost always fitted with the components needed for high volume
aspiration such as tip support, Mini-Separator and shutting valves. In case these devices
are not already fitted, the supplier of the aspiration system shall install these components
inside the unit (with manufacturer's authorisation) or in other suitable positions.

Tip support
(draw. 30a pag. 85)
The tip support is generally fixed on the water unit L. Dental ergonomics suggest also
different positions; they must be found together with the professional in order to meet his
own practice requirements in any working position.

Canisters and separators

(draw. 6-15-29-30a-33a-33b-34a-34b pag. 13-85-87-88-89-90)
Only the more conventional installations, dry systems, pose the
problem of canisters and Mini-Separators inside the surgery. Semi-
dry systems need no separator inside the dental unit. In semi-dry
systems aspirated liquids flow along the whole aspiration circuit and
are drained in the engine-room: in large installations a Separator-
Tank, G draw. 29, collects all the aspirated debris from all the
surgeries, separates air from liquids and drains the latter in the

waste. In small installations the same operation is carried out by a
centrifugal system, separating air from water and draining the latter
in the waste, draw. 33a-33b-34a-34b.
In air ring systems, due to lack of room, the Canister (separator of
blessed memory) has almost disappeared, to be replaced by the
automatic Mini-Separator, draw. 6. When the dental unit design
does not offer any room, or anyway the assembling of the Mini-
Separator is too difficult to assure a proper running, a good solution
is Maxi-Canister plus box, draw. 15, placed at the bottom of the chair
on the left (out of the dentist's and the assistent's operation range).
Tip support and Separator must be installed so that liquids are
drained by gravity,
in order to avoid stagnations of liquids inside the pipings connecting
the components when the aspiration is switched off; such liquids
could be difficult to be aspirated rapidly on the restarting of the
aspiration and could cause some annoying standstills. The draining
of the separator is worth particular attention: the draining pipe must

be able to drain 1.5 - 2 l/min.
