If you do not intend to use the instrument for several weeks you may turn it off.
Please note, however, that it may take up to several hours to cool the cryochamber down
to very low temperatures after turning the instrument on again.
After turning off, the instrument should be cleaned and disinfected thoroughly (see
chapter "9. Cleaning, Disinfection, Maintenance").
Switch the instrument off at the circuit breaker and unplug the power plug.
• Open the sliding window to allow the cryochamber to dry.
• Remove all the specimens from the cryostat.
• Lock the handwheel.
• Take the knife/blade out of the knife/blade holder. Put the knife back in the knife case; push
the blade into the receptacle for used blades provided at the bottom of the dispenser ( Fig. 33 ).
• Remove all section waste with a cold brush.
• Empty the section waste tray.
• Remove the storage shelves and the brush shelf for cleaning and disinfection.
Switching off the instrument via the circuit breaker will not affect the programmed values.
Before turning the instrument on again, the cryochamber microtome and all accessory compo-
nents must be absolutely dry.
