Translation of the original operating manual
3.6.3 Fire prevention
Fuses protect certain electrical circuits within the freeze-dryer against over-
current conditions.
• Always use fuses of the same type and rating.
• Do not dry explosive or inflammable substances.
• Do not use the freeze-dryer within hazardous locations where there is a
risk of explosion.
3.6.4 Thermal safety
During the operation of the freeze-dryer, the ice condenser can reach
surface temperatures of –85°C depending on the power.
• Wear suitable protective gloves when installing or removing
accessories. Do not reach into the ice condenser chamber without this
protection – your limbs may freeze onto the chamber walls!
3.6.5 Chemical and biological safety
If infectious, toxic, pathogenic, or radioactive substances are intended to be
dried, it is in the responsibility of the user to ensure that all necessary
safety regulations, guidelines, precautions, and practices are adhered to
accordingly.
• Infectious, toxic, pathogenic, and radioactive substances must be dried
in suitable accessories. Take suitable precautions for your own safety!
• Do not dry products with a high solvent concentration or acidic
products without special protective measures or device-based
precautions (e.g. an additional cooling trap to protect the vacuum
pump). It is absolutely necessary to consult the manufacturer in these
cases (see chapter 7.3 - "Service contact").
• Special caution is necessary when handling azides, as a dangerous
explosive develops in combination with copper or nonferrous metals! It
is absolutely necessary to contact the manufacturer (see chapter 7.3 -
"Service contact").
• Keep informed about local measures to avoid harmful emissions
(depending on the substances to be dried).
• As personal protective equipment, safety gloves are required for the
use of the freeze-dryer.
The materials to be dried may, however, require additional special
safety measures (e.g. drying of infectious, toxic, radioactive, or
pathogenic substances).
