Accessories for aspiration units

(draw. 27 pag. 83)
For every aspiration unit is available a line of accessories including: vibration-proof devices A,
tube-holder sleeves, special tube B, low frequency silencer C fitted with non-return valve D, high
frequency cylindrical silencer E and compensating valve F. If the unit is fitted with deadening box,
the accessories are included there. On request it is available a certified bacteriological filter to
filter the exhausted air.

Electrical control panels

(draw. "A"-"B"-"C" pag. 81-82-80)
Every aspiration unit must be coupled to an electrical control panel with technical features
suitable for the motor input assorbine and fitted with all the safeties required by safety regulations.
Control panels, aspiration units and feeding lines must be protected against electrical
direct and idirect contact, from overload and overcurrent, in compliance with C.E.I. 64-8
regulations (E.C. corresponding regulations available on request) for first class appli-
ances. Tables "A", "B" and "C" show the indications for the choice of the control panels in relation
to the aspiration units. On request, control panell can be equipped with: hour-counter, warning
lights check, motor-off signal, tension control, manual/automatic running mode-switch.

PLANNING

Aspiration pipings
(draw. "A"-"B"-"C"- fig. 28 pag. 81-82-80-84)
The diameter of the aspiration pipings is related to several factors as the number of the
surgeries that will work at the same time, the aspiration unit which has been chosen and
the route of the pipings. Tables "A", "B" and "C" show the different diameters in relation to
various cases. Pipes must be of the best quality, of heavy type offering long lasting
guarantee. Also the layout of the whole piping must facilitate the flowing of the fluids,
avoiding as much as possible any loss of pressure due to friction. It is necessary that every
branching off and extension is made by 45 ° connections bent towards the surgeries, A;
also 90 ° bends should be avoided as far as possible, they can be substituted by two
45 ° bends, B. In dry systems the aspiration pipings do not create any problem of levels or
counterslopes, on the contrary in semi-dry systems, where aspirated liquids flows along
the whole aspiration circuit, it is necessary to avoid upward slopes and syphons. When
the pipes are run in chases they must be inspectable; at the end of every branch it is always
possible to insert a proper tool but when the pipings route does not allow a complete
inspection from these openings, then some inspection holes should be placed at the most
suitable points, C. It is advisable to check the tightness of the pipeline once it has been
positioned: the test is useful in an dry system, essential in a semi-dry system. Once all
outlets have been stopped up, pipings must be put under light pressure and checked with
a suitable instrument (manometer, mercury or water column): pressure should be steady.
Electrical wiring
(draw. 28 pag. 84)
Aspiration units and control panels must be installed in a special technical room, purposely
prepared and fitted with all safety devices required by safety regulations and, if necessary, under
authorization and surveillance of responsible authorities. In the technology room, even when not
expressly required by regulations, we suggest using self-extinguishing material, a fire
extinguisher outside as well as suitable guards for the equipment. Electrical feeding line will
be prepared according to tension and input shown on the control panels, on the aspiration
