other with higher flow, we recommend their installation at a longer distance from the surgery,
draw. 29. Every engine room will be fitted with: an electrical feeding line proportionate
to the power installed, with a switch and an high sensitivity differential; an outlet to
exhaust outside the aspirated air and to ventilate properly the room (min. temp. +5 ° C
- max. temp. +30 ° C). Air exhausted from the aspiration units is always very damp and its
temperature is higher than the room one; due to rarefaction, some condensation, which
must be discharged, can form in the draining pipe.
The manufacturer offers a certain number of accessories like: brackets, deadening boxes,
low frequency silencers, draw. 27-C, high frequency silencers E, vibration-proof devices A,
hoses B and heat-resistant pipes H.
These accessories are not always indispensable, but they are often useful to prevent
inconveniences and troubles. Tables "A", "B" and "C", pag. 81-82-80, give some information
useful for the choice of the aspiration units and of the control panels according to the number
of surgeries supposed to be working simultaneously.
Assembling of two or more aspiration units in parallel lowers absorbtion costs when
the plant is not in full use and reduces the risk of total failure. In systems made up of two
or more machines in parallel, operation controls and luminous/acoustic signals are useful
both in the technological room and in the secretary's office; otherwise a progressive stop of
the system might occur. It is thus advisable to request the controls and signals listed below.
Useful controls and signals: operation hour-counter, luminous switches with machine
operation modes (manual and automatic), luminous signal test push-button, phase-on
tester.
Luminous and acoustic signals for failures: suction assembly, drainage pump, full tank,
mix separator maximum level.
The reader is kindly requested to note that even if the sound pressure levels data (reported
at the units illustrations) have been gathered systematically and precisely, they can be
anyhow influenced by environment, by machines position and by others factors; conse-
quently eventual discrepancies should be considered as resulting from these situations or
from data gathering methods.
Control panels and aspiration
units
(draw. "A"-"B"-"C"-27-28-29-30a pag. 81-
82-80-83-84-85)
Control panels, canisters, aspiration units and,
as a rule, all appliances connected to the power
mains, especially when switching on and off are
automatic and take place without previous no-
tice, must be installed in an engine room, where
the entry is forbidden to patients and unauthor-
ized persons. For small plants fitted with aspi-
ration units: Uni-Jet 75, Mini-Jet 2V, Uni-Jet 75
2V, Tecno-Jet, Tecno-Jet 2V and Flux-Jet, the
engine room can be obtained in one of the
surgery rooms, draw. 30a; a minimum deaden-
ing will be enough to reduce the noise to accept-
able levels.
In the power 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. As for aspiration units Flux-Jet 2V,
Medio-Jet, Medio-Jet 2V, Maxi-Jet 2S and
