  • Page 3: Safety Information

    1. 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. 1.1 WARNING SYMBOLS The following are the warning symbols that are used in this manual.

  • Page 4: Intended Use

    2. INTRODUCTION 2.1 INTENDED USE The CF-220 Centrifuge is a universal laboratory centrifuge. It is designed for use in medical, scientific and industrial laboratories, for separating the substances with dif- ferent specific densities by centrifugal force. In particular, it is intended for preparation of human samples (body fluids), in approved test tubes, before further analysis.

    After installation, it is recommended that you wait for some time, before connecting the centrifuge to the mains power supply. This pre- vents damage to electronic components due to condensation, which can occur, when you bring the device from a cold environment to a warm environment.

    3.2 TURNING ON THE CENTRIFUGE Use the enclosed power cord to connect the centrifuge to the mains power supply. Turn on the main switch, which is located on the front of the left side of the centrifuge. All segments are displayed on the display at first, then program version (VX.X), then centrifuge type and then centrifuge model CF-220, and finally the value of last dis- played operation parameter is displayed.

  • Page 10: Rotor Loading

    3.5 ROTOR LOADING You must always load the rotor with test tubes symmetrically. You may only use approved test tubes. Weight difference of the samples in test tubes should be as low as possible in order to avoid potential damages to the motor and to minimize running noise and vibration.Following are examples of correctly and wrongly loaded rotors: CORRECT CORRECT...

    3.6 SETTING THE ROTATIONAL SPEED AND CENTRIFUGAL FORCE By pressing LEFT and RIGHT keys, select the operation parameter you wish to set (rota- tional speed, centrifugal force, run time, acceleration level and braking level). Then use UP and DOWN keys to set the value of selected operation parameter. •...

  • Page 12: Program Setting

    Changing of run time during the 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. The centrifuge started with time set to 10 minutes.

  • Page 14: Starting And Stopping The Centrifuge

    3.8 STARTING AND STOPPING THE CENTRIFUGE Before starting the centrifuge, turn on the main switch, open the centrifuge lid, insert the rotor and load it with test tubes, close the centrifuge lid and set the operation parameters or select a suitable program. By pressing the START key, you start the run of the centrifuge.

  • Page 15: Rotor Recognition

    3.9 ROTOR RECOGNITION Several rotors can be used (RA 24/2, RA 12/5, RA 12/12, RA 8/15, RA 6/50, RA 4/PCR, RH 24), so rotor recognition is executed automatically every time the centrifuge starts, and maximum rotational speed is set (6,000 RPM or 15,500 RPM), to correspond with the inserted rotor.

  • Page 16: Auxiliary Lid Release

    3.13 AUXILIARY LID RELEASE In case of power failure, the lid can be opened manually. If power failure occurs during the operation of the centrifuge, the rotor may continue rotating for several minutes, before it stops. Before auxiliary lid release, turn off the main switch of the centrifuge and wait until rotor fully stops.
  • Page 17 4. MAINTENANCE AND CLEANING OF THE CENTRIFUGE 4.1 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. 4.2 CLEANING THE CENTRIFUGE After every centrifugation, please remove any condensed water from the rotor chamber using a soft, absorbent cloth.

    5.2 EXIT FROM ERROR DISPLAY By pressing the STOP key, you exit from error display and go back to stand-by mode. If error is still displayed, turn off the main switch of the centrifuge and turn it on again. If the centrifuge still doesn’t return to stand-by mode, call service! 5.3 USER’S PARAMETERS With user’s parameters, you can check and set some of the operational properties of the centrifuge.
