Warnings
Before using, read this operation manual to ensure correct usage and thorough understanding of the
instrument. Incorrect handling could possibly result in personal injury or physical damage of the unit or its
accessories. The manufacturer accepts no responsibility for any damage caused by mishandling that is
beyond normal usage as defined in this manual. The manufacturer is only responsible for the security,
reliability and performance of the instrument, if the unit is operated in accordance with the operating
instructions. Any adjustments, changes or repairs must be performed by authorized personnel.
NOTES AND WARNINGS
Notes and warnings appear throughout this manual to provide additional information and directions so that
specific actions can be taken to protect both personnel and the instrument.
Safety Information
For your own safety, please review the following precautions:
NEVER use a power source other than that designated for the instrument.
NEVER operate the instrument, if it has not been installed or repaired properly. Repairs must be
performed only by qualified personnel authorized by VWR
NEVER use unapproved rotors and associated components. Contact the manufacturer prior to
such use to prevent possible damage to the instrument.
NEVER attempt to open the lid or move the instrument unless the rotor is completely stopped.
NEVER operate the instrument without a rotor and lid installed correctly and secured to the
motor shaft.
NEVER centrifuge flammable, toxic, radioactive, explosive, or corrosive materials.
This symbol indicates additional warnings to prevent actions that may result in equipment
damage, property damage, or personal injury.
NOTE
Notes are intended to provide additional information to clarify specific instructions or
highlight information requiring special attention.

7
NEVER exceed the rated speed or specific gravity. Samples whose density is greater than
1.2 g/ml must have reduced maximum rotational speed to avoid rotor failure.
ALWAYS load the rotor symmetrically with evenly weighted samples to avoid rotor imbalance. If
necessary, use the water blank to counterbalance the unpaired sample.
NEVER use Biosafety rotor without lid
ALWAYS locate the instrument on a flat, level, rigid, and vibration free surface.
ALWAYS mark a safety zone of 30 cm around the centrifuge to indicate that neither hazardous
materials nor persons should be permitted within the area during operation, as safety regulations
required.
ALWAYS position the instrument with additional free space on each side of instrument to ensure
proper ventilation.
ALWAYS install the instrument within a temperature and humidity controlled environment.
(Permissible ambient temperature: +5 °C –+35 °C, Relative humidity: ≤ 80 %)
ALWAYS disconnect the power supply prior to maintenance and servicing to avoid electrical
shock. Do not immerse.
ALWAYS use proven disinfection procedures when centrifuging bio-hazardous materials.
Please follow the guidelines above, and read this manual in its entirety to ensure safe operation of the unit.
NOTE
When it is required to handle the Risk Group II materials that are known to be toxic,
radioactive materials or pathogenic micro-organisms, as identified in the World Health
Organization (WHO): “Laboratory Biosafety Manual,” the guidelines recommended by
WHO should be followed to ensure the safety.

Installation
1. Inspect the instrument and the parts for any visible signs of shipping damage.
2. Unpack the unit and verify the contents of the package.
3. Place the instrument on a clean, flat, level, and vibration free surface.
4. Plug the power cord into the appropriate power outlet.
WARNING!
Safety regulations require a safety zone of 30 cm around the centrifuge that
needs to be marked to indicate that neither hazardous materials nor persons
should be permitted within the area during operation.
Proper ventilation is necessary to prevent the overheating of samples.
NOTE
Check that the power supply corresponds with the manufacturer’s specified electrical
requirements.

Turn the power on. The switch is located on the rear side of the unit.
5. Once the power is applied, the door will be opened automatically.
6. Carefully place the rotor onto the motor shaft. Hold the rotor with one hand and securely tighten
with the supplied rotor wrench the rotor nut to the shaft by turning clockwise.
