Important Safety Information
Certain potentially dangerous conditions are inherent to the use of all
centrifuges. To ensure safe operation of this centrifuge, anyone using it should
be aware of all safe practices and take all precautions described below and
throughout these operating instructions.
Mechanical Safety
W A R N I N G
For operator safety, maintain a 30-cm "clearance envelope" around the
instrument while the rotor is spinning. Do not store dangerous substances
capable of developing flammable or explosive vapors in the clearance
envelope.
Do not attempt to unlock the door forcefully while the rotor is spinning.
Do not attempt to slow or stop the spinning rotor by hand.
Do not incline or move the instrument while the rotor is spinning. Do not lean
on the instrument.
If abnormal sound or vibration occurs, stop the operation immediately and
contact Thermo or your local representative of Thermo Fisher Scientific
products.
C A U T I O N
Before using a rotor, be sure to read through the rotor instruction manual.
Maximum rotor speed depends on the rotor, buckets, assemblies, tubes or
adapters to be used. Follow the instructions in the rotor instruction manual.
Do not use corroded, scratched or cracked rotors, buckets and assemblies.
Check that the rotor, buckets and assemblies are free of such abnormalities
before operation.
When using a swinging bucket, check that the buckets are properly engaged
with the rotor pins before operation. An incorrect setting can cause severe
damage to the instrument.
Be sure to mount the rotor cover if provided. Check that the rotor cover is
completely secured with a screw if provided.
Mount the rotor onto the drive shaft (drive spindle) gently and properly. Do not
drop the rotor or apply excessive force to the drive shaft (drive spindle).
Clean the inside of the drive hole (drive spindle hole) of the rotor and the
surface of the drive (drive spindle) of the centrifuge once a week.
If condensation is in the rotor chamber, wipe the chamber dry with a dry
sponge or cloth.

Safety During Installation and/or Maintenance.
Electrical Safety
CAUTION
Do not pour any solution such as water, detergent or disinfectant directly into
the rotor chamber. Otherwise, the bearings of the drive unit may corrode or
deteriorate.
Before relocating the centrifuge, remove the rotor from the rotor chamber to
avoid damage to the drive shaft.
Always keep the liquid crystal panel in a visible position while the POWER
switch is turned on, so that you can check the current operating state (running
or stopping).
DANGER
When servicing the centrifuge, be sure to turn off the POWER switch, turn off
the distribution board of your centrifuge room, and then wait for at least three
minutes before removing covers or tables from the centrifuge to avoid electrical
shock hazards.
WARNING
Level the centrifuge by using the four level adjusters and secure them
completely. Improper securing can cause significant movement of the
centrifuge in the event of a rotor disengagement.
Installation or relocation of your centrifuge must be done by Thermo Fisher
Scientific or a Thermo Fisher Scientific representative. Contact Thermo Fisher
Scientific or your local representative of Thermo Fisher Scientific products
CAUTION
Avoid places that are exposed to ultraviolet rays for operation or storage of the
centrifuge. Otherwise, the covers can be discolored and the coating can be
peeled off easily. If installation in such a place is unavoidable, cover the
centrifuge with a cloth after operation to protect from ultraviolet rays.
WARNING
Your centrifuge must be grounded properly to avoid electrical shock hazards.

Preface

Safety Against Risk of Fire
Chemical and Biological Safety
Notice for an Earthquake
An abnormality may be found on the centrifuge depending on the magnitude of
an earthquake.
If any abnormality is found, stop using the centrifuge immediately and ask for
inspection by Thermo or your local representative of Thermo Fisher Scientific
products.
CAUTION
Do not place containers holding liquid on or near the instrument or in the rotor
chamber. If they spill, liquid may get into the instrument and damage electrical
components.
WARNING
This instrument is not designed for use with materials capable of developing
flammable or explosive vapors or extreme exothermic reactions. Do not
centrifuge such materials in this instrument nor handle or store them near the
instrument.
WARNING
When using radioactive, toxic, or pathogenic materials, be aware of all
characteristics of the materials and the hazards associated with them in the
event leakage occurs during centrifugation. If leakage does occur, neither the
centrifuge nor the rotor can protect you from particles dispersed in the air. To
protect yourself, we recommend additional precautions be taken to prevent
exposure to these materials, for example, use of controlled ventilation or
isolation areas.
Always be aware of the possibility of contamination when using radioactive,
toxic, or pathogenic materials. Take all necessary precautions and use
appropriate decontamination procedures if exposure occurs.
The use of sealed rotors, buckets and/or sample containers will provide
increased protection from contamination during routine operation. However,
these items will not guarantee contaminatio protection from accidents resulting
in damage to the rotor or buckets. Do not run hazardous materials in the
centrifuge unless placed in a biohazard enclosure and operated using all
appropriate safety precautions.
