3. CLEANING

3.1. Standard Cleaning
The instrument must be cleaned immediately in the
following cases:
· the piston is difficult to move
· change of reagents
· after lengthy periods of non-use
· before any maintenance and repair work
· before sterilisation
3.1.1. Preparations for Cleaning
Wear eye protection, protective clothing and protective
gloves. Avoid splashing of reagent.
1. Place the screwed-on instrument together with the bottle
in a washbasin.
2. Move the lever (12) to the Return setting ( ).
3. Empty the piston by pressing it down.
4. Unscrew the instrument from the bottle. Then pull out
the instrument until the intake tube (11) is no longer
immersed in the liquid.
5. Carefully tap the intake tube against the inside of the
bottle until the reagent has drained out of the intake
tube.
6. Lift the instrument off the bottle.
7. Set the lever (12) to Dispense (q).
8. Hold the discharge tube above the bottle opening and
return any remaining reagent to the bottle.
IMPORTANT! During cleaning or bottle change, reagent is
still present in the discharge tube even in the Return setting;
after emptying the piston, set the lever (12) to Dispensing
(q) so that the discharge tube can be emptied.
WARNING: Avoid injuries due to chemicals! The instrument,
intake tube and discharge tube may still contain reagents,
so never point the opening towards the body! Wear eye
protection, protective clothing and protective gloves.
3.1.2. Cleaning Process
1. I mmerse the intake tube in a suitable cleaning solution.
Clean it by repeated dispensing of the maximum
volume.
2. Move the lever (12) to the Return setting ( ) and also
rinse out the return duct.
3. Use a pure solvent (e.g. distilled water or acetone)
for repeated further dispensing.
