12. Maintenance and Cleaning

Basically, we recommend UV disinfection (see page 35 for detailed instructions).

For easy-to-use spray disinfection we recommend Leica Cryofect. (Cryofect is not available in all countries!)

The cryostat has to be disinfected after each daily use.

Comply with the instructions for use!

The glass anti-roll plate can remain in place during disinfection.

It is not necessary to oil the parts, such as the T-piece on the microtome base plate, clamping lever etc.

•In case of visible pollution (such as dust), clean the air inlet opening (Fig. 10, p. 18) of the condenser on the bottom right-hand side of the instrument using a brush, broom or extraction cleaner in the direction of the louvers.

Do not turn the instrument on before the cryochamber is completely dry!

Frost formation!

The front panel and the slit cover of the microtome must be com- pletely dry before turning on the instrument!

Dry all parts completely before reinserting them in the cryochamber!

12.2 Changing Fuses

•In case of power supply faults, please contact an authorized Leica service technician immediately.

Do not carry out any repairs on your own as this will invalidate the warranty.

Repairs may only be carried out by qualified service engineers authorized by Leica.
