✓Ready.
4.4 Execution
Prerequisite:
▪Conveyor system is switched off and secured against being switched on again
▪Conveyor system is prepared for cleaning
Info
The most efficient way to clean a conveyor is from top to bottom and from the centre
to the outside.
Perform the following steps:
1. Remove residue of conveyance goods.
2. Dry cleaning:
Remove coarse dirt without damaging the surface of the conveyor belt as well as gear wheels,
shafts and other parts (e.g. guide rails, slide rails etc.).
3. Rinse off:
Rinse conveyor belt with warm water (52 °C to 54 °C) and a pressure of 10 to 20 bar.
4. Application of the cleaning agent:
Apply suitable cleaning agent to the conveyor at a pressure of 10 bar.
Allow cleaning agent to act for 10 to 15 minutes.
ǃDo not allow cleaning agent to dry in (danger of chemical compounds).
5. Rinse and inspect:
Thoroughly rinse the conveyor belt with water at a pressure of 2.8 to 4.1 bar and a temperature
of 52 °C to 54 °C.
ǃInspect conveyor (sensory analysis: See, smell and feel) and ensure that dirt, cleaning
agent, water and other residues have been rinsed away.
ǃTake care when using strong cleaning agents.

Cleaning
17
Quick installation guide_Conveyor system MB-flex S N_20221114_EN.docx
6. pH value test:
Inspect the conveyor again. Ensure that all residues of the chemical cleaning agent have been
removed from the conveyor belt.
To do this, check with a pH strip (litmus paper) whether all residues of the alkaline solution
have been removed.
Run the conveyor belt slowly to dry the conveyor belt. Meanwhile, remove accumulated water
from the floor.
7. Check and release for disinfection:
Check conveyor belt again by sensory analysis and disinfect.
ǃUse an adenosine triphosphate (ATP) test to confirm/exclude the presence of bacteria.
ǃIf the ATP test is positive, clean the checked area again.
8. Disinfection:
Run the conveyor belt again at a slow speed. Use disinfectant as specified by the
manufacturer.
ǃTake care not to apply too much disinfectant so that the conveyor does not need to be
rinsed.
ǃRemove excess disinfectant via the drain.
✓Ready.
