Safety Instructions
1.5.1 CAUTION! Disconnect Mains Plug!
As current-carrying parts are accessible inside the unit the mains plug must be
disconnected before the side panels are opened. For maintenance the unit must be
switched off with the mains switch.
1.5.2 CAUTION! Solvents!
Acidic products or products with a high solvent concentration cannot be dried without
special protective measures and devices such as e.g. a cooling trap for protection of
the vacuum pump (if necessary check with our service department).
Special caution is necessary when using azides because a dangerous explosive
develops in combination with copper or non-ferrous metals! It is absolutely
essential to consult our company!
1.5.3 ADVICE! Cleaning and Maintenance of the Unit!
For infectious, toxic, pathogenic and radioactive substances the corresponding safety
regulations must be observed.
1.5.4 WARNING! Freezing of Limbs to surfaces!
During operation of the freeze dryer dangerous situations in the ice condenser
chamber may arise. When putting in the shelves take care that limbs do not come into
contact with the condenser in the ice condenser chamber as the limbs may become
frozen to the surface. The limb can only be detached from the surface by applying
heat. Liquid should not be used.
