3. OPERATION
3.1 Mounting and loading rotor
3.1.1 Installation of rotors
Clean the drive shaft as well as the collet with a clean, grease-free piece of cloth. Place the rotor onto the drive
shaft. (See figure below) Take care that the rotor is fully installed onto the motor shaft.
Figure.10 Figure.11 Figure.12

FrontierTM Centrifuge FC5706 EN-5
Hold the rotor with one hand and secure the rotor to the shaft by turning the fixing screw clockwise. (See figure 12)
ATTENTION:
Check that the fixing screw is properly installed before each run.
Do not operate the centrifuge with rotors or buckets which show any signs of corrosion or mechanical
damage.
Do not operate with extremely corrosive substances, which could damage the rotor, buckets and
materials.
In case of any questions, please contact the manufacturer!
3.1.2 Loading angle rotors
Rotors must be loaded symmetrically and with equal weight (See figure below). The adapter may only be loaded
with the appropriate vessels. The weight differences between the filled vessels should be kept as low as possible.
Therefore we recommend weighing them with a balance. This reduces the wear of the drive and the acoustic
operating noise.
On each rotor, the maximum load per hole is stated. (It is only allowed to operate e.g. a 12-place-rotor with 2 ,4 or
8 loaded tubes. But the loaded borings must be opposite each other).
Figure.13-1 WRONG Figure.13-2 CORRECT (6 tubes)
3.1.3 Loading swing out rotors
Loading of the buckets / vessels must be made in accordance with figure 16. It is only allowed to operate e.g. a 4-
place-rotor with 2 loaded buckets, with the loaded buckets located opposite to each other and the unloaded
buckets put inside the rotor (See figure below).
In principle, swing out rotors may not be taken into operation until all buckets or racks are put into the rotor.
The sample tubes have to be filled evenly by eye and put into the drillings or tube racks. The weight difference of
the loaded buckets should not exceed 1 g.
ATTENTION!
Swing out rotors may be taken into operation only if all locations are filled in with either four buckets or
four carriers –do not mix buckets and carriers up!!
Figure. 16-1: WRONG Figure. 16-1: CORRECT

EN-6 FrontierTM Centrifuge FC5706
ATTENTION!
Do not operate the centrifuge with rotors or buckets which show any signs of corrosion or mechanical
damage.
Do not operate with extremely corrosive substances, which could damage the rotor and buckets.
In case of any questions, please contact the manufacturer!
3.1.4 Loading and overloading of rotors
All approved rotors are listed with their maximum speed and maximum filling weight in "table 2 permissible net
weight" (See APPENDIX).
The maximum load permitted for a rotor, which is determined by the manufacturer, as well as the maximum speed
allowed for this rotor (See label on rotor), must not be exceeded. The liquids the rotors are loaded with should have
a maximum homogeneous density of 1.2 g/ml or less when the rotor is running at maximum speed.
In order to spin liquids with a higher density, the speed has to be reduced according to the following formula:
Reduced speed nred = √1,2
ℎ𝑖𝑔ℎ𝑒𝑟 𝑑𝑒𝑛𝑠𝑖𝑡𝑦 x max. speed (nmax) of the rotor
Example:
nred = √ 1,2
1,7 x 4,000 = 3,360 rpm
In case of any questions, please contact the manufacturer!
3.1.5 Removing the rotor
Untighten the rotor fixing nut completely (screw over the stiff point) and lift the rotor vertically out of the centrifuge.
(See figure 12)
3.2 Power switch
The power switch is located on the bottom left side of the unit (see figure 17).
Figure. 17: Power switch
3.3 Lid control
3.3.1 Lid open
After the run, when closing the lid of the centrifuge, in the display "RPM | RCF" (A-1) the word "close" (M1)
appears (refer to figure 18 below).
If there is a rotor in the centrifuge, additional the word "rotor"(M3) appears, as well as the code number of the
respective rotor which is in the centrifuge system "77" (M4). If there is no rotor in the centrifuge, the word "rotor"

The speed is adjustable between 200 rpm and maximum revolution of the centrifuge resp. the maximum
permissible revolution of the pre-selected rotor.
It is the same as the pre-selection of the RCF-value. The setting range is between 20 x g and the maximum
permissible centrifugal force of the rotor.
The maximum speed of the FC5706 is 6000 rpm resp. 4427 x g.
See "Table 3: max. speed and RCF-values for permissible rotor" (See APPENDIX). All important values are
listed there.
ATTENTION:
Please also check the maximum permissible revolutions of your test tubes with the manufacturer.
3.4.2 Preselection of running time
The running time can be pre-selected in three different ranges from 10 seconds up to 99 hours 59 minutes.
1. Range from 10 seconds up to 59 minutes 50 seconds in steps of 10 seconds
2. Range from 1 hour up to 99 hours 59 minutes in steps of 1 minute
3. The continuous run "cont", can be interrupted by the key "Stop"(10).
The running time can be pre-selected with the lid open or closed.
To activate the setting of the running time press the key "Time" (6).
In the display "Time" (A-3) the indication "m : s" or "h : m" flashes, depending on the previous setting.

Please pay special attention to anodized aluminum parts. Breakage of rotors can be caused even by slight damage.
In case of rotors, buckets or tube racks getting in touch with corrosive substances the concerned spots have to be
cleaned carefully.
Corrosive substances are for instance: alkalis, alkaline soap solutions, alkaline amines, concentrated acids,
solutions containing heavy metals, water-free chlorinated solvents, saline solutions, e.g. salt water, phenol,
halogenated hydrocarbons.
Cleaning –units, rotors and accessories:
- Turn the device off and disconnect it from the power supply before you begin any cleaning or disinfecting. Do not
pour liquids into the housing interior.
- Do not spray disinfectant on the device.
- Thorough cleaning not only has its purpose in hygiene but also in avoiding corrosion due to pollution.
- In order to avoid damaging anodized parts such as rotors, reduction plates etc., only pH-neutral Detergents with a
pH-value of 6-8 may be used for cleaning. Alkaline cleaning agents (pH-value > 8) must not be used.
- After cleaning, please ensure all parts are dried thoroughly, either by hand or in a hot-air cabinet (max.
Temperature + 50°C).
- It is necessary to coat anodized aluminum parts with anti-corrosion oil regularly in order to increase their life-
spans and reduce corrosion predisposition.
- Due to humidity or not hermetically sealed samples, condensate may be formed. The condensate has to be
removed from the rotor chamber with a soft cloth regularly.
The maintenance procedure has to be repeated every 10 to 15 runs, or at least once a week.
- Connect the unit to the power supply, after the equipment is completely dry.
- Do not carry out disinfection with UV-, beta- and gamma-rays or other high energy radiation.
- Metal rotors can be autoclaved.
- Rotor lid and adapters can also be autoclaved (max. 121°C, 20 min).
- The tube racks are made of PP and cannot be autoclaved at 134°C.

5.1.2 Cleaning and disinfection of the unit
1. Open the lid before you turn off the unit. Disconnect it from the power supply.
2. Open the rotor nut by turning the rotor key counter clockwise.
3. Remove the rotor.
4. Cleaning and disinfect the unit and the rotor chamber using the above mentioned cleaner.
5. Clean all accessible areas of the device and its accessories, including the power cord with a damp cloth.
6. Wash the rubber seals and rotor chamber thoroughly with water.
7. Rub the dry rubber seals with glycerol or talc to prevent these from becoming brittle. Other components of the
unit, e.g. the lid lock, motor shaft and rotor must not be greased.
8. Dry the motor shaft with a soft, dry and lint-free cloth.
9. Check the equipment and accessories for damage.
Make sure that the centrifuge is turned off the unit and disconnect the unit from the power supply. Then remove
adherent dust from the ventilation slots in the centrifuge by using a soft brush. Do this at least every six months.
5.1.3 Cleaning and disinfection of the rotor
1. Clean and disinfect the rotors, rotor lids and adapters with the above mentioned cleaner.
2. Use a bottle brush to clean and disinfect the rotor bores.
3. Rinse the rotors, rotor lid and adapter with clear water. Particular the drillings of angle rotors.
4. For drying of the rotors and accessories set them on a towel. Place the angle rotors with bores down, to dry
them to.
5. Dry the rotor cone with a soft, dry and lint-free cloth and look for damage. Do not grease the rotor cone.
5.1.4 Disinfection of aluminum rotors
In case of infectious material spilling into the centrifuge, the rotor and rotor chamber have to be disinfected right
after the run. Rotors may be autoclaved at a maximum temperature of 121°C.
5.1.5 Disinfection of PP-rotors
Autoclaving
The recommended time for autoclaving: 15 –20 min at 121°C (1 bar)
ATTENTION:
The sterilization time of 20 min. must not be exceeded. Repeated sterilization will cause reduction of
the mechanical resistance of the plastic material
Before autoclaving the PP-rotor and adapter must be thoroughly cleaned to avoid the burning in of dirty
residues.
You can disregard the consequences of some chemical residues to plastic materials at ambient temperatures. But
at the high temperatures during autoclaving those residues may corrode and destroy the plastic. The objects must
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 seriously pollute the rotor chamber, the rotor, the buckets
and the samples.

If necessary, replace the adapters, tubes and accessories to avoid further damages. Check the rotor bores
regularly for residues and damage.
ATTENTION:
Please check the relevant specifications of the tubes with the manufacturer.
5.2 Lifetime 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 and recommended care.

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 protect your
samples.
Please proceed as follows:
1. Switch the centrifuge off and unplug the power cord, wait until the rotor stands still (this may take several
minutes)
2. At the left side of the centrifuge housing there is a plastic stopper (see figure 28). Remove this stopper,
fastened to it there is a string which is connected to the electronic lid lock.
3. If you pull the string slightly the lid will open.
ATTENTION:
Don’t put your hands in the rotor chamber as long as the rotor is still spinning!
Push the plastic stopper back in the unit again, to continue working
