7. Maintenance
7.1.
If the unit requires maintenance, disconnect the unit from the electric circuit and
contact Biosan or your local Biosan representative.
7.2.
All maintenance and repair operations (such as fuse replacement) must be performed
only by qualified and specially trained personnel.
7.3.
Standard ethanol (75%) or other cleaning agents recommended for cleaning of
laboratory equipment can be used for cleaning and decontamination of the unit.
7.4.
Improper magnetic stirring elements storage (storing several elements together,
which causes unpredictable magnetic domain disorientation) is one of the reasons
for deterioration of magnetic properties of the stirring element. The other reason is
working at temperatures close to Curie point temperature of the elements, which is
200°C. Place the element on the working surface exactly in the centre in conformity
with the poles. Leave the element for 8-12 hours for it to regain its initial
characteristics.
