Cleaning/Disinfecting
Damage to the product due to inappropriate cleaning/disinfecting agents and/or
excessive temperatures!
Use cleaning and disinfecting agents approved for e.g. aluminum, plastics and
high-grade steel, according to the manufacturer's instructions.
Observe specifications regarding concentration, temperature and exposure time.
CAUTION
Do not exceed the maximum allowable cleaning temperature of 93 °C.
Carry out ultrasound cleaning:
– as an effective mechanical supplement to manual cleaning/disinfecting,
– as a pre-cleaning procedure for products with encrusted residues, in preparation for mechanical cleaning/
disinfecting,
– as an integrated mechanical support measure for mechanical cleaning/disinfecting,
– for additional cleaning of products with residues left after mechanical cleaning/disinfecting.
Manual cleaning/disinfecting
Keep working ends open during cleaning.
Clean products with movable links with the links opened or mobilized.
Inspect visible surfaces for residual contamination after manual cleaning/disinfecting.
Repeat the cleaning process if necessary.

Stage I
Fully immerse the product in the cleaning/disinfecting solution. Make certain that all accessible surfaces are
moistened.
Clean the product under running tap water, using a suitable cleaning brush if necessary, until all visible residues
have been removed from the surfaces.
Brush through surfaces not accessible to visual inspection, e.g. in products with hidden crevices, lumens or
complex geometries, for at least 1 min or until no more residues can be removed, using an appropriate cleaning
brush (brush head length: 50 mm/∅: 3.7 mm, e.g. GK469200).
Mobilize non-rigid components, e.g. set screws, links, etc. during cleaning.
After cleaning, thoroughly (at least five times) rinse through these components with the cleaning/disinfecting
solution, using a disposable syringe (20 ml).
Do not use metal cleaning brushes or other abrasives that would damage the product surfaces and could cause
corrosion.
Stage II
Rinse the product completely (all accessible surfaces) under running water.
Allow water to drip off for a sufficient length of time.
Stage III
Fully immerse the product in the disinfecting solution.
Rinse lumens at least 5 times at the beginning of the exposure time, using a disposable syringe (20 ml) and an
appropriate rinsing adapter. Make certain that all accessible surfaces are moistened.
Stage IV
Carry out a full rinse of the product (all accessible surfaces) under running water.
Rinse lumens at least 5 times at the beginning of the exposure time, using a disposable syringe (20 ml) and an
appropriate rinsing adapter. Make certain that all accessible surfaces are moistened.
Allow water to drip off for a sufficient length of time.
Stage V
Dry the product with lint-free tissue or medical-quality filtered compressed air.
Mechanical cleaning/disinfecting
Note
The disinfector must be of proven effectiveness (e.g. DGHM or FDA approval or CE mark).
Note
Use appropriate (neutral, enzymatic and mild-alkaline) detergents for this product with aluminum components.
Note
For thermal disinfection, always use fully desalinated (demineralized) water. Ensure that Ao is >3 000 for the process.
Note
The disinfector used for processing must be serviced and checked at regular intervals.
Place the product on a tray that is suitable for cleaning (avoid rinsing blind spots).
Connect components with lumens and channels directly to the rinsing port of the injector carriage.
Keep working ends open during cleaning.
Ensure that product links and joints are opened when placing the product on the tray.

Stage I
Clean the product in an ultrasound cleaning bath (frequency 35 kHz). Make sure that all accessible surfaces are
moistened and acoustic shadows are avoided.
Clean the product with a suitable cleaning brush until all visible residues have been removed from the surface.
Brush through surfaces not accessible to visual inspection, e.g. in products with hidden crevices, lumens or
complex geometries, for at least 1 min or until no more residues can be removed, using an appropriate cleaning
brush (brush head length: 50 mm/∅: 3.7 mm, e.g. GK469200).
Mobilize non-rigid components, e.g. set screws, links, etc. during cleaning.
After cleaning, use a 20-ml single-use syringe to rinse thoroughly, for at least 5 times, these difficult to access
parts of the product.
Do not use metal cleaning brushes or other abrasives that would damage the product surfaces and could cause
corrosion.
Stage II
Rinse the product completely (all accessible surfaces) under running water.
Allow water to drip off for a sufficient length of time.
Stage III
Fully immerse the product in the disinfecting solution.
Rinse lumens at least 5 times at the beginning of the exposure time, using a disposable syringe (20 ml) and an
appropriate rinsing adapter. Make certain that all accessible surfaces are moistened.
Stage IV
Rinse the product completely (all accessible surfaces) under running water.
Rinse lumens at least 5 times, using a disposable syringe (20 ml) and an appropriate rinsing adapter.
Allow water to drip off for a sufficient length of time.
Stage V
Thoroughly dry the product with lint-free tissue or medical-quality filtered compressed air.
Mechanical cleaning/disinfecting with manual pre-cleaning
Note
The disinfector must be of tested and approved effectiveness (e.g. DGHM or FDA approval or CE mark according to DIN
EN ISO 15883).
Note
For thermal disinfection, always use fully desalinated (demineralized) water. Ensure that Ao is >3 000 for the process.
Note
The disinfector used for processing must be serviced and checked at regular intervals.
