• Clean the ventilation slits (5) of the liquefier on the right side of the instru-
ment with a brush, broom or vacuum cleaner from dust and dirt in the
direction of the fins.

The microtome can be removed for thorough cleaning and disin-
fecting, or for extensive drying after a long power failure!
The germicidal UV lamp is a simple and safe disinfection device
which considerably reduces the risk of infection. Nevertheless, UV
light disinfection cannot replace chemical disinfection of the
cryochamber at regular intervals. UV light disinfection is effective
only on those surfaces that are directly illuminated.
9.3.2 Removal of the microtome
Turn the instrument off and disconnect the mains plug before re-
moving the microtome.
Prior to removing the microtome, place the specimen head to the
lowest position by placing the handle of the handwheel in the low-
est position.
When removing the microtome, the specimen head will rapidly fall
down and might injure the operator‘s hands.
Wear appropriate protective gloves to take the cold microtome out
of the cryochamber!
Extended skin contact with cold parts of the instrument may cause
frost bite!
• Slightly lift the sliding window when closed holding it at the grip provided

age shelf, right storage shelf.
