2. Safety and Design
2.6Handling Specimens – Defrosting
•When working with contaminated or infected material, the general safety guidelines for laboratories must be applied.
•Before defrosting the cryochamber remove all samples!
•Before defrosting the specimen head, remove all samples!
Never leave samples in the cryochamber! - The instrument is not suitable for storing frozen specimens, as the refrigeration dehy- drates the specimens!
The quick freeze shelf can become very hot during the defrosting process. Do not touch it during defrosting.
2.7Removal of the Microtome
•The microtome is encapsulated and therefore does not require removal by the user.
2.8Maintenance
Replacing the fuses
•Turn the instrument off and disconnect the power plug before replacing the fuses.
•Use only the fuse types specified in chapter 3, "Technical Data." Failure to comply with this can cause severe damage to the instrument!
Replacing the fluorescent lamp/UVC lamp
•Turn the instrument off and disconnect the power plug before replacing the lamps.
It is possible to break the UVC lamp during replacement. If this happens, the lamp change must be completed by Technical Ser- vice. If any metallic mercury is released, handle it carefully and dispose of it properly.
If both disinfection indicator lights are blinking alternately, the
UV tube must be replaced!
