Maintenance
7.1
Decontaminating the instrument
If the instrument has been used to process biohazardous samples, the fluidics system is to be decontaminated
by running the standard shutdown sequence. Refer to Excessive debris is present during acquisition on
page 79 if you would like to perform the clean program with 1% sodium hypochlorite. Use tissues or swabs to
decontaminate surfaces. The uptake needle of the robotic arm and the surface of the instrument shall be
decontaminated upon contact with biohazardous samples. It is recommended to use the appropriate
disinfectant for the potential pathogen.
7.2
Exchanging fluid bottles
1 Install one bottle at a time. Remove the bottle to be exchanged from the bottle basket.
2 Place a new, sealed bottle into the orange bottle holder. Note the corresponding color coding.
3 Remove the cap of the new fluid bottle.
4 Remove the bottle closure from the old bottle and install it on the new bottle. Do not disconnect the color-
coded tube and sensor cable from the bottle closure. Take care not to invert the bottle closures, as this
could cause liquid to enter the hydrophobic air filter.
7.3
Exchanging hydrophobic air filters
Hydrophobic air filters are attached to the bottle closures to vent the liquid bottles and the fluidic system. To
avoid clogging of the filters and to prevent contamination of the liquids, exchange the hydrophobic air filters if
they come into contact with liquid. To avoid clogging due to deposition of dust, exchange filters once a year.
Use only the hydrophobic air filters from Miltenyi Biotec (# 130-090-385).
1 To exchange the air filter of the fluidics system, remove the Single tube rack if installed.
2 Open the right front cover.
3 Exchange the hydrophobic air filter.
4 Close the front cover.
5 Attach the Single tube rack if desired.
7.4
Cleaning the dropping station
1 Remove the Single tube rack.
2 Open the cover of the dropping station to the left side. Warning! Potentially contaminated liquid may spill
out of the orifice of the dropping station and the tubing.
3 Clean the dropping station by wiping it with tissue and an appropriate disinfectant, e.g. 70% ethanol,
isopropyl alcohol, or 10% bleach. Finally, rinse with distilled water.
