Operation And Use - cattani Mono-Jet Alpha Gebrauchsanweisung

• Operation and use

The supply cable of the aspirator is provided of protec-
tion cable for earthing; this protection must not be remo-
ved for any reason and must fi t perfectly in the supply plug.
When the installation has been completed, the unit can be
switched on by the main switch.
When the switch 1 is in ON position (ill. B), it lights up; lifting
one of the terminals from its seat will start the aspiration.
We recommend to use the brand-new, non contaminated
appliance to train the surgery staff about the use and stan-
dard maintenance operations.
Opening of the door of the cabinet interrupts the circuit and
the aspirator stops. On normal assembly the aspirated air
is exhausted through the silencer 2 (ill. C). Simply connect a
pipe from the motor outlet to an outside tube 3C preferably
passing through the bacterial fi lter with active carbons 4 (ill.
C), to convey the air outside: bacteria and most of the noise
will be carried outside together with air.
• Operation and use
Through the tip and the lifted hose, liquids and aspirated air
get to the manifold 4 (ill. L) and from there to the canister
through pipe 3A (ill. B). In the canister liquids are separated
from air: the air goes to the motor through pipe 3B (ill. B)
and is then exhausted; on request a certifi ed bacterio-
logical fi lter is available to fi lter the exhausted air (ill.
C pag. 4). Liquids, heavier than air, are collected on the
bottom of the canister. Draining is automatic: the valve 6
(ill. D), placed on the bottom of the canister, is kept closed
by depression when the aspirator is working; when all ter-
minals are replaced on the tip support, the aspiration stops
and liquids are drained from the canister (ill. D).
If the canister fi lls up during an operation, probes 5 (ill. D)
will sense the maximum level at about 3/4 of the canister
with the shortest probe; the electrical circuit will open and
stop the aspiration automatically; the draining valve 6 will
open automatically and the draining pump 8 (ill. C) will start:
within few seconds the canister will be emptied and the
aspiration can re-start automatically.
Blood, mucus and disinfectants can easily form foams that
interfere with probes and interrupt suction.
Therefore we recommend using antifoaming tablets. If any
running anomaly (block of the cooling system, breakdowns
ecc.) causes an overheating of the motors (i.e. temperature
rises above 120 °C in the Uni Jet 75 - aspiration unit - and
above 90 °C in the draining pump 8), thermal protectors
with prefi xed temperature value will open the circuits and
reset them automatically as soon as the windings get back
to normal temperature.
Obviously the causes of the interruption should be ascer-
tained and rectifi ed.
