7.6.2 Shutdown for a longer period
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 and mainte-
nance').
• Turn the instrument off with the automatic mains fuse.
• 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 holder. Put the knife back into the
knife box or push the blade into the receptacle for used blades provided
at the bottom of the dispenser.
• Remove all section waste with a cold brush.
• Empty the section waste tray and remove it for cleaning and disinfec-
tion.
• Remove the storage shelves and the brush shelf for cleaning and disin-
fection.
Turning off the instrument with the automatic mains fuse will not affect the
programmed parameters.
Before turning the instrument on again, the cryochamber microtome and all
accessory components must be absolutely dry.
