Safety Reminder Common safety precautions Carefully read the following safety precautions for a thorough understanding. z Follow the instructions and procedures described in this manual to operate this centrifuge safely. z Carefully read all safety messages in this manual and the safety instructions on the centrifuge. z Safety messages are labeled as indicated below.
with pathogenic micro-organisms. Use of these is at your own responsibility. z If the centrifuge, rotor and accessories that have been contaminated by solutions with toxic, radioactive or pathogenic materials, clean it according to the decontamination procedure as specified. z If you require service at site, please sterilize and decontaminate the centrifuge in advance, and then notify the service center the details of the materials and procedure.
z Vibrations are likely to damage the centrifuge, contact our service center if abnormality observed. 1. Specifications Maximum speed 14000rpm(200-14000rpm), increment: 10rpm Maximum RCF 18620×g, increment: 10×g Maximum capacity 2ml×24, 0.
equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. 3.

14000 rpm 25 ℃ 12 min Figure 6-2 The main interface Main interface is as figure 6-2. The speed is set to be 14000rpm, temperature of centrifugal chamber is 25℃, and the running time is 12 minutes. When speed symbol is rotating, this indicates the centrifuge is running. If the rotation is faster, the speed is higher. Temperature of chamber is displayed and cannot be controlled. Time symbol into 10 sections. displays the ratio of working to time setting. The total time setting is divided 7.
7.5 Symmetrically load centrifuge tubes into rotor CAUTION z Make sure the rotor lid is securely fixed on the rotor, as well as the rotor and shaft are tightened. Otherwise, the rotor may be moved off while rotating and cause damage to the centrifuge and rotor. z Firmly tighten the rotor lid to the rotor. 8. Operation CAUTION z Do not push or lean against the centrifuge while it is running. z Do not run the centrifuge when fragments or sample solutions are left in the centrifuge chamber.
Figure 8-2 indicates the centrifuge has accumulated running time 312 hours 56 minutes and 45 seconds, and then the centrifuge displays the last running parameters, see figure 8-3 below: 14000 rpm 25 ℃ 12 min Figure 8-3 Last running interface z Speed: 14000rpm; running time: 12minutes; centrifugal chamber temperature: 25℃ z Release the door. 8.1.
8.1.2 Set the operation programs Press the button to select required program. The parameter can be modified when the program is flashing. Rotate the program button clockwise button clockwise to increase parameter value. Rotate the program to decrease parameter value. Rotate the program button faster, and the parameter value will increase faster. The minimum speed increment is 10 rpm, the minimum time increment is 1 second.
（3）Warning display z If an error occurs during the operation, the centrifuge will brake to stop automatically, and display the error code on the time/display area. The error code can be checked in the table 10-1, and corrective actions can be applied accordingly. 8.1.4 End the operation （1）The centrifuge will brake when it reaches the set time or z button is pressed. When the rotor stops rotating, the centrifuge will start beeping to alert the operation has finished.
8.3 Pulse operation This function is used to remove the residual samples adhered to the interior of the tubes or for quick spins. Note：The button works only while the rotor stopped and the door is locked. （1）Turn on the power switch and load the rotor to the shaft, tighten the rotor lid and make sure it is in secured position, and then close the door. （2）The centrifuge goes into preparation mode and displays last running values. （3）Press knob and hold, the centrifuge will speed up to the setting speed.
（3）Drive shaft z We recommend regular maintenance for drive shaft. You can wipe the drive shaft with soft cloth, and then apply a thin coat of silicon grease. （4）Door z Clean and sterilize the door using the same method as the section（1）above. （5）Rotor z To prevent corrosion, remove the rotor from rotor chamber. If not in use for a long term, then detach the rotor lid and turn upside down to dry the tube holes and keep clean. z For sample leaks in the rotor, rinse the rotor with water.
10. Troubleshooting 10.1 Possible problems and solutions This centrifuge has a self-diagnostic function. If a problem occurs, an error/warning code will be displayed on the time display screen, and the operator can determine the malfunction with the alarm code below. Symptom Causes Solutions Nothing appears on the screen when the ·Facility power is turned on. breaker tripped. power circuit ·Correct and turn on the power. ·The fuse has blown. ·Replace the fuse.
10.2 How to open the door 10.2.1 In the case of power on CAUTION z The door just can be opened while the power is on and rotor stops rotating. （1） Turn on the power switch, release the door automatically. （2） The door will be released automatically once the operation is finished. （3） It is available to release the door by press button once the rotor stops. 10.2.2 In the case of power outage The door cannot be opened automatically if there is a power outage.

11.2.4 Conditions and life expectancy of tubes The life expectancy of plastic tubes depends on the characteristics of samples, speed of the rotor used, temperature applied and so on. When the plastic tubes are used for ordinary aqueous samples (pH between 5.0 and 9.0), their life expectancies are defined as follows. Be operated at the maximum speed: High quality tubes (PA、PC、PP): 30-50 operations Ordinary tubes(PA、PC、PP): around 10 operations（Using in low speed can extend the tube life）.
