HOW TO AVOID MALFUNCTIONS


Before turning on the instrument, check that
all stations are covered. Please note that the
covers put on properly.

Check for correct liquid level.
Note:
The containers are marked showing
the max.
solutions should be filled to approx. 1 –
2 mm below this mark and wash solutions (H
alcohol, Xylene etc.) approx. 1 – 2 mm above this
mark. This way, it is guaranteed that the staining
solutions are rinsed off properly.

Insert the basket with specimens into the
basket carrier in a correct way.

To avoid glass damage, insert the slides into
the intended guidance of the basket.

The drawer for the entry and exit stations
must be closed. By no means, open it while
the basket carrier is just inserted or removed
from a station.

Check, if the charcoal filter has been inserted.
Danger:
The instrument must not be operated
without charcoal filter, as the vapors
are then released unfiltered into the
ambient air.

Moreover, sufficient space (approx. 15 cm) for
ventilation must be guaranteed on either side
of the instrument.

Correct water
guaranteed.

Water flow must be free from impurity (e.g.
rust precipitation). If necessary, add a filter.

The water drain must have a constant
declination.

Do not mark the covers of the stations, as
they are replaced during a protocol run.

Do not place heavy objects onto the hood.

Before turning off the instrument, please note
that all protocols have been processed.
Warning:
Turn off the water flow after having
finished the daily routine.

After having finished the daily work, shut
down the instrument in a controlled way.
