against sprinkles and accidental contacts with infected parts; ensure that no repair or
inspection is carried out on machines in operation or on ones connected to the mains.
Machine casing is not only a means to reduce noise level but also a protection against
accidental contacts and (infected) spray of machines under pressure. Any machine
installation must be carried out by a specialist, duly trained and equipped with the necessary
tools. The installer must refer to the appliance manual to carry out the machine fi nal test and
to instruct users on use and routine maintenance. Engineers duly trained and equipped with
the necessary tools must carry out technical maintenance.
Make sure that periodical checks are carried out on systems and equipment.
Such an inspection is not only a means to prevent the surgery from forced stops
and to check its operating conditions, but it is a proper way to prevent accidents and
fi res (according to Italian law 626).
Air exhausted from the aspiration units pollutes and heats up the room, so it is
recommended to sterilise it, by means of an absolute fi lter (det. A fi g.10) and to
convey it outside.
Controls and light signals (remove to the secretary room or to another room under control
a general danger warning or a failing-machine-one; if the signal is on, check and then call
for an authorised engineer): working hour-meter, machine-on signal, tension and amperage
checking, temperature checking, light signal test.
Light and sound signal for serious breakdown: stop of an aspiration unit, room
temperature exceeding 35 °C, stop of a draining pump or full tank.
Wherever a separate technical room cannot be installed, a reliable solution can be Blok-Jet
(fi g. 10) is also manufactured in a soundproof and refrigerated version. Blok-Jet is, as a
rule, a combination of aspiration unit, compressor and control panels; it is assembled,
cabled and tested by the manufacturer, therefore the installer is only liable for correctly
locating and plugging the system.

Piping layout

(fi g. 1 page 50)
The diameter of the main duct (or collecting pipe A) must be proportionate to the fl ow of
the aspiration unit. Branches (B) from the surgeries will be connected to the main duct
by means of 45° connections (C) bent towards the surgeries.
Where necessary, inspection holes (D) should be included in the plan to allow for
inspection inside aspiration piping. As a rule, the location of the piping must comply
with the laws of physics on the dynamics of fl uids into a pipe.
A slope of the piping towards the pump will facilitate its functioning, pipe on the
same level will give no problems, but counter-slopes compromise functioning
proportionately to the gradient of the slopes. In liquid and semi-wet installations,
siphons and counterslopes in the tubes cause stoppages in suction. Once the
piping is installed, it is advisable to carry out a tightness test: all outlets should be
closed up, the piping should be put under slight pressure and checked with a suitable
instrument; pressure must remain steady. An electrical cable for low-tension controls
will run along the piping.

Functioning

(fi g. 8-9-11 page 57-58-59)
Knowing how the appliance operates will make the surgery staff self-sufficient and
self-confi dent.
Users and staff charged of maintenance must read the manual and refer to it so to
get a perfect knowledge of the machine and/or the system.
Along with liquids, some solid particles are also aspirated so it is necessary to fit a
fi lter next to the dental unit to retain particles greater than 0.8 mm. The fi lter on our tip
