After a drying process, some or all of the surfaces inside the chamber

DANGER
Risk of poisoning/infection caused by the products
When performing maintenance work on parts coming into contact with the
product (e.g. all parts inside the chamber, vacuum pump), the personnel
may be exposed to product residues.
Skin contact or the inhalation of particles may cause severe damage to
health depending on the product in question.
• Take suitable decontamination measures prior to commencing the
maintenance!
• Wear suitable protective clothes and gloves!
• Switch the freeze-dryer off by actuating the mains power switch and
disconnect the power cord from the wall outlet before cleaning.
• If the freeze-dryer has been contaminated with toxic, radioactive, or
pathogenic substances, clean the inside immediately with a suitable
decontamination agent (depending on the type of contamination,
see chapter 8.2 - "Disinfection of the drying chamber and accessories").
• Remove product residues thoroughly with a cloth.
• Open loading door when the freeze-dryer is not in use so moisture can
evaporate.
