Frontier Centrifuge FC5714/FC5718/FC5718R/FC5816/FC5816R
be thoroughly rinsed with distilled water after the cleaning but before the autoclaving. Residues of any cleaning
liquids may cause fissures, whitening and stains.
Gas sterilization
Adapters, bottles and rotors may be gas sterilized with Ethylenoxyd. Make sure to air out the items after the
sterilization and before using them again.
ATTENTION:
Because the temperature may rise during the sterilization, rotors, adapters and bottles must not
be closed and must be totally unscrewed
Chemical sterilization
Bottles, adapters and rotors may be treated with the usual liquid disinfectants.
ATTENTION:
Before applying any other cleaning or decontamination method than recommended by the
manufacturer, contact the manufacturer to ensure that it will not damage the unit or the rotor.

5.1.6 Glass breakage

With high g-values, the rate of glass tube breakage increases. Glass splinters have to be removed immediately
from rotor, buckets, adapters and the rotor chamber itself. Fine glass splinters will scratch and therefore damage
the protective surface coating of a rotor. If glass splinters remain in the rotor chamber, fine metal dust will build up
due to air circulation. This very fine, black metal dust will significantly pollute the rotor chamber, the rotor, the
buckets and the samples.
If necessary, replace the adapters, tubes and accessories to avoid further damage. Check the rotor bores regularly
for residues and damage.
ATTENTION:
Please check the relevant specifications of the tubes centrifuges with the manufacturer.

5.2 Life time of rotors, buckets, accessories

Rotors and rotor lid made of aluminum or stainless steel, have an operating time of max. 7 years from first use.
Transparent rotor lids and caps made of PC or PP as well as rotors, tube racks and adapters of PP have a
maximum operating time up to 3 years from first use.
Condition for the operating time: Proper use damage-free condition, recommended care.

6.2 Survey of possible error messages and their solutions

6.2.1 Lid release during power failure (Emergency Lid Release)

In case of power failure or malfunction, the lid of the centrifuge can be opened manually in order to retrieve your
samples.
For FC5718/FC5718R/FC5816/FC5816R (motor driven lock)
Please proceed as follows:
1. Switch off the centrifuge and unplug the power cord, wait until the rotor has come to a standstill (this may take
several minutes)
2. On the left side of the centrifuge housing there is a plastic stopper. Remove this stopper and behind it there is a
hexagon nut.
3. Take the included box spanner, put it in the hole and lock the box spanner with the hexagon nut (See figure 37).
4. Now turn the box spanner to the right side (clockwise) up to the limit.
