Leica Biosystems EG1160 - Manual (Page 26)

26 Instruction manual V 4.1 – 05/2001
Regular cleaning and maintenance will keep your Leica EG 1160 in good
operating condition for many years.
1. General instructions: Paraffin
- Paraffin is flammable and therefore must be handled with care. Avoid
spillage of liquid paraffin.
- All Leica EG 1160 components that come into contact with paraffin and
the interior of the instrument are carefully sealed to prevent wax from
entering. Nevertheless, if paraffin is spilled, it should always be removed
carefully.
- The paraffin reservoir and cassette bath, if required, should be filled with
care. Avoid overfilling!
- The wax in the cassette bath and heated recessed area must be ex-
changed every day to avoid contamination.
- Solid wax particles on the surface of the work area must not be removed
with sharp tools, as this could damage the finish. A soft plastic spatula is
ideal for wax removal. Alternatively, solid paraffin can be lifted off easily
by lightly warming it.
- The surfaces of the work area of the Leica EG 1160 are made of alu-
minium with polyester epoxy finish. The control board is covered with a
PE film. The base of the housing is a polyester epoxy coated steel plate.
All seams are sealed with a specific fungicidal silicone.
All materials are easy to clean with common laboratory detergents, which
are appropriate for paraffin removal. Do not allow organic solvents to
react for a longer period. Apply varnish protection occasionally.
Caution:
Xylene must not be used for cleaning. Although xylene is an ideal wax sol-
vent, its flash point ranges between 27 and 32°C. Xylene vapours are heavier
than air and can catch fire even if the source of heat is at a larger distance.
Therefore, it is not appropriate for cleaning hot or potentially hot surfaces.
Risk of fire!
