Safety Information Before using the machine, make sure to read and understand this manual thoroughly. Keep the manual close to the machine, easily accessible to all the users. Improper operation can cause injury to persons or damage to the equipment. In the interest of your own personal safety, always observe the following safety instruc- tions: Do not use rotors and buckets, which show clear signs of corrosion or mechanical defects.
Intended Use The CF-350 is a laboratory centrifuge intended to be used in laboratories for separating the substances with different specific densities by centrifugal for In particular, it is intended for preparation of human samples (body fluids), in approved test tubes, before further analysis.
Retain the packaging material for any subsequent transport or storage, which are allowed only in the original packaging. The CF-350 Centrifuge consists of the following: Description Quantity...
Control Panel Description Before using the centrifuge for the first time, familiarize yourself with the control panel and the functions of the knob and keys. Run Indicator (four lamps) Display for rotational speed (RPM) and centrifugal force (RCF) Indicator for selection indication between rotational speed (RPM) and centrifugal force (RCF) Knob for setting and selecting between rotational speed (RPM) and centrifugal force (RCF) Display for time, acceleration level (AcX) and braking level (brX) Knob for setting and selecting between time, acceleration level (AcX) and braking level (brX)
Knob and Button Functions SHORT PRESS: By pressing this key, you start and end the run of the centrifuge. When you press the key for the first time, the centrifuge starts to run. When you press it again, the centrifuge stops. The next run is possible, when the rotor stops completely.
Rotor Loading Test tubes in the rotor must always be loaded symmetrically. You may use only approved test tubes. Weight difference of the samples in test tubes should be as low as possible in order to avoid potential damages of the motor and to minimize running noise and vibration.
Setting the Rotational Speed and Centrifugal Force By rotating this knob, you change the values of the parameters. By rotating the knob to clockwise direction, the values are increasing, and by rotating it to counter-clockwise direction, they are decreasing. By pressing on the knob you choose between: •...
NOTE: All the operation parameters can be changed during the operation of the centrifuge, and it starts to work with the new settings after that. • Changing the run time during operation You should be aware, that when you extend run time, the difference between newly set and originally set time is added to current time, and when you shorten run time, the difference is subtracted.
Display the Set Values During the Run During the run, the centrifuge shows the current values of the operation parameters on displays. If you wish to check the set values of the parameters, select the desired parameter by pressing the corresponding key. The key lights up.
Maintenance and Cleaning of the Centrifuge Regular Service We recommend having the centrifuge and associated rotors checked by authorized service at least once a year. You must thoroughly clean and disinfect the centrifuge prior to service. Cleaning the Centrifuge After every centrifugation, please remove any condensed water from the rotor chamber using a soft, ab- sorbent cloth.
Troubleshooting If an error occurs during the operation of the centrifuge, an error message appears on the display, and the centrifuge stops automatically. The display shows message ERROR and number of the error EXX (XX is the error number). Display Responsi- Problem Solution...

Users Parameters Accessing Parameters With user’s parameters, you can check and set some of the operational properties of the centrifuge. For entering to user’s parameters, the centrifuge must be in stand-by mode. Simultaneously press the LEFT and RIGHT keys. The first parameter shows on display (ror). Then you can select the parameters by pressing the LEFT and RIGHT keys.
Replacing the Centrifuge Fuses The following fuses are required for CF-350 Centrifuge: 2 x 16AT 250V (120V) 2 x 10AT 250V (230V) • Unplug mains plug from the mains socket. • By pressing the locking device on the left side of the fuse compartment, the fuse holder is released and you can pull it out.
Appendix Calculation of Centrifugal Force For the calculation of the centrifugal force (RCF), stated as a multiple of the gravitational force “g”, use the following formula: RCF ..Relative centrifugal force ( x g) RCF = 11.18 x r x ( n / 1000 )2 r ....
