INSTALLATION – OPERATION – MAINTENANCE
Following works must be carried out from the hygiene and the correct aspirator function points of
view.
9.1. Inlet Sieve Cleaning
Solid particles (sucked together with a liquid component and the air) are entrapped in the inlet sieve
(7) during the equipment operation (Enclosure No. 1, Fig. 1) which therefore must be regularly
cleaned, by section 8 (though, always at the end of each shift).
The inlet sieve cleaning is possible only after the moisture inside suction tubings (6) and a sieve is
reduced by means of the several seconds lasting air suction through tubings taken off the holder (2).
Then turn the power-supply switch (5) off in the position „O" and slightly lift the cover of the inlet
sieve. Afterwards pull the sieve out of its place gripping the holder, remove solid particles and clean
the sieve. Then put the sieve on the previous place into the holder and carry out the assembly in the
contrary manner to the dismantling.
If the suction of amalgam particles is expected, it is necessary to empty the inlet sieve content into
a closing vessel and forward it to the collecting centres.
9.2. Lubricating seals and sliding closures
O-rings (sealing rings) and sliding terminal clamps (Enclosure No. 1- pos.1) must be lubricated using
a suitable silicone oil for dental applications (e.g. Lubri-Jet spray) every 15 working days.
9.3. Disinfection of Tubings and Separation Vessel
For the separation vessel (11) disinfection it is necessary to empty the same, rinse with warm water
and clean mechanically with warm water and a disinfectant.
The disinfection of internal suction tubings and of the separation vessel should be performed by
section 8, though always at the end of a shift by suction of warm water containing a disinfectant
having a limited foaming power through both suction tubings (6) separately. The used disinfectant
must be approved in compliance with a valid national legislation on usage for disinfected surface
and a type of material. For the disinfectant use, follow the maufacturer's instructions.
9.4. Cleaning and disinfection of the exterior surfaces of the product
Use neutral agents for cleaning and disinfection of the external surfaces of the product.
The use of aggressive cleaning agents and disinfectants comprising alcohol and
chlorides may lead to the damage of the surface and the discoloration of the
product.
To find out whether the aspirator works correctly, the following works should be carried out in the
defined maintenance intervals:
9.5. Replacement of the Output Pre-filter
It is necessary to replace the output pre-filter (15) by section 8. Before making any replacements
turn the aspirator power-supply switch (5) off. The pre-filter together with the filter (14) are situated
on the left lower part of the aspirator's bogie having the symbol
For its dismantling, catch the filter holder (13) with one hand and with the other hand slew the fixing
lugs (16) by 90° by simultaneous pulling down. Remove the filter holder together with the output
filter. Then release the output pre-filter from the cavity wherein also the output filter was situated
(check also the state of pollution of the output filter).
For the reassembly, set the output filter into the filter holder, put the output pre-filter onto the filter
(direct the output pre-filter with the gummed cloth towards the filter) and insert all the assembly into
the cavity space from below. Slew the fixing lugs back by 90° so that they engage into the recessed
parts of the filter holder.
