Handling and care of rotors and accessories made of aluminium
The aluminium parts are anodised and protected against corrosion to a
large extent. Avoid damaging the surface of aluminum parts in order to
lengthen their lifetime.
Clean aluminum parts as follows:
• Use warm water with a neutral solvent.
•
Never use caustic cleaning agents such as soap suds, phosphoric acid,
bleaching solutions or scrubbing powder.
•
Rinse the cavities out thoroughly.
•
Use a soft brush without metal bristles to remove stubborn residue.
• Afterwards rinse with distilled water and dry the parts off with a soft
cloth.
• Place the rotors on a plastic grate with their cavities pointing down.
•
If drying boxes are used, the temperature must never exceed 50 °C,
since higher temperatures could damage the material and shorten
the lifetime of the parts.
•
Use only disinfectants with a pH of 6-7.
• After cleaning, rub the aluminium parts entirely with anti-corrosion
oil (7000 9824) using a soft cloth.
•
Also treat the cavities with oil.
• Store the aluminum parts at room temperature or in a cold-storage
room with the cavities pointing down.
