HIGH SPEED ASPIRATION
The best performance is obtained from your high speed aspiration system if the simple operating and
maintenance instructions below are strictly adhered to. Failure to comply with these instructions would
jeopardise the performance of the aspirator performance, sometimes with serious consequences.
After each intervention, we recommend aspirating clean water for a few seconds in order to rinse the
tubing. Dental tips must be thoroughly cleaned and sterilised: We recommend brushing the cannulas both
inside and outside using the supplied pigs (to be found in the “aspiration system accessory kit”) and a
suitable detergent.
Aspiration end pieces supplied by O.M.S. can be autoclaved at a temperature of 130°C.
In order for the aspirated deposits not to clog the filter and corresponding aspiration tubing the following
washing cycle must be carried out at the end of each working day.
For this operation use the products recommended by the aspiration system manufacturers.
1.
Use one of the two aspiration cannulas to aspirate the amount of solution indicated in the bottle
making sure that only the cannula end is introduced into the bottle.
2.
Let the aspirator run for 3 to 4 minutes, then stop it. Drain the liquid and repeat the previous
operation with the other cannula. Aspirate using one cannula at a time so that the other cannula can
be used for air suction, thus preventing the aspiration system from getting blocked due to an
excessive aspiration of liquid.
3.
Unscrew the drain plug and clean the filter inside the drain (in the column). Replace it, if necessary.
Periodically grease the drain and plug mouthpiece with vaseline, because disinfectants may stiffen
these parts, thus making plug extraction difficult.
Do not mix detergents having different features.
Never immerse aspiration tubes if they do not fit the required cannula.
