Leica CM1520 – Cryostat

2.7 Removing the microtome

• The microtome is encapsulated and therefore does not require removal

by the user.

2.8 Maintenance

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 and its

surroundings!

Replacing the fluorescent lamp

• Turn the instrument off and disconnect the power plug before replacing

the lamps. (More details are in Chapter 9, "Cleaning, Disinfection, Main-

tenance.)

2. Safety

• Do not use organic solvents or other aggressive substances for cleaning.

Use only disinfectants listed in these Instructions for Use, such as Leica

Cryofect (alcohol or other common alcohol-based disinfectants).

For additional detailed information about disinfection, contact

Leica Biosystems.
