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.
