1.5. Safety instructions
1.5.1. CAUTION! Disconnect the mains plug!
As current-carrying parts are accessible inside the unit
the mains plug must be disconnected before the side panels or the
rear panel are opened or before the control panel is removed.
For maintenance work 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, for example, cooling trap for protection of the
vacuum pump (if necessary check with our factory). The unit can
also be damaged by corrosion.
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 factory!
1.5.3. ADVICE! Cleaning and Maintenance of the Unit!
For infectious, toxic, pathogenic and radioactive
substances, the danger information of the associated 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, make sure that no limbs come into contact with the
condenser in the ice condenser chamber as the limbs may freeze
to the surface. The limb can only be detached from the surface by
applying heat. Liquid should
not be used.
