2. Safety
2.1.2 Operating the instrument
• The instrument may only be operated by
skilled personnel. It may only be operated
according to its designated use and in ac-
cordance with the instructions given in this
manual!
• While working with reagents (filling / emp-ty-
ing the reagent stations, working on the in-
strument while the lid/s is/are open) appro-
priate protective gear (lab coat, gloves, safe-
ty goggles) must be worn!
• Make sure to operate the instrument ei-ther
with the activated carbon filter or with the
exhaust air hose (--> Chapter 3.6, ‘Installing
the accessories’). Even when the instrument
is operated according to its designated use,
hazardous solvent fumes develop, which are
damaging to the operator’s health and do
also pose a risk of fire!
• Risk of fire, when working with an open
flame (Bunsen burner) immediately next to
the instrument (solvent fumes)! - Therefore,
keep a safety distance of 1 meter!
• If ‘Alarm off’ is selected (not recommend-
ed!), the instrument must be observed con-
stantly, to make sure all slide racks are re-
moved immediately when reaching the last
station!
• If not only the water tap but also the ball
valve has been closed (--> e.g. when setting
up the instrument), the tap water flow rate
has to be adjusted when starting a program
(see also chapters 3.6 and 6.8.3).
• The flow rate must not be too fast, to en-sure
that the specimens remain firmly at-tached
to the slide surface!
• If a staining program is to be interrupted for
an extended period of time, do not leave any
slide racks in the tap water sta-tions, in order
to prevent them from drying out!
• As soon as the alarm is triggered, immediate-
ly remove the completed slide rack from the
last station or from the unload container of
the optional unload station! Otherwise, im-
mersion times for the remaining slide racks
will be prolonged!
• In case of emergency switch off mains and
unplug the power chord!
