6.2.2 Internal Surface
If accidental spilling of biological material occurs in the carousel area of the instrument or if more thorough
cleaning is needed:
1. Remove all reagents and materials (including magnets) from the carousel.
2. Rotate the carousel so that quadrant #1 faces the front side of the instrument.
3. Unscrew the black central knob (Figure 24) counterclockwise until the threads have disengaged.
4. Lift out the carousel.
5. Clean any spilled biological material according to the good laboratory practices described by your
institution. Clean the carousel and magnets by lightly spraying with 70% ethanol or 70% isopropanol and
wiping clean with a soft, clean towel. Exercise caution when cleaning the gaskets located within the
reagent vial and 14 mL sample tube locations. Ensure you do not overly bend or permanently crease the
plastic fingers of the gaskets during the cleaning process.
6. Place the carousel back into the instrument so that quadrant #1 faces the front side of the instrument, and
screw the central knob clockwise until locked back into place.

6.3 Replacing the Fuses
If RoboSep™-S does not turn on after plugging it in and following the startup procedure (section 3.3), the
fuses may need to be replaced.
Two fuses are located on the back of the instrument next to the power supply outlet and the main power
switch (Figure 11). To replace the fuses:
1. Ensure that RoboSep™-S is shut down (section 3.4) and that the main power switch located on the back
of the instrument (Figure 11) is turned OFF.
2. Unplug the instrument and open the fuse box.
3. Examine the fuses and replace any faulty fuse with a FB 4 A 250 V~.
4. Reinsert the fuse box containing the new fuse(s) in its slot. Press gently until it snaps back into place.
5. Plug in the instrument and start up RoboSep™-S (section 3.3) to check if it turns back on.
