76 Instructions for Use, V1.9, RevD - 12/2012
Wash and reagent vessels
Clean the wash and reagent vessels in the laboratory dishwasher at maxi-
mum +65 °C. Use a standard laboratory dishwasher detergent.
The vessels may not be exposed to temperatures any higher
than 65 °C (e.g. do not clean in industrial dishwashers, which
run at a temperature of 85 °C), as the stations might become de-
formed!
Drain outlet / hose
From time to time check the waste water drain hose for accumulated dirt,
particularly for algae. Clean whenever necessary.
To prevent the growth of bacteria, the drain system may be flushed with
5% sodium hypochlorite. Metal parts may, however, not be exposed to this
solution for a lengthy period of time (e.g. overnight). Therefore, rinse with
abundant water after cleaning with sodium hypochlorite.
Slide racks
Clean with household or laboratory cleaners, as needed.
Oven
Regularly check the paraffin collecting tray(s) at the bottom of the oven(s)
for paraffin residues and clean, if necessary.
6.2 General maintenance
The instrument is virtually maintenance-free in operation.
To ensure smooth operation of the instrument over many years we do,
however, recommend the following:
• Have the instrument inspected once per year by a qualified service en-
gineer authorized by Leica.
• At the end of the warranty period, enter into a service contract. For
more information, please contact your local Leica technical service
center.
