1.1 Attention for installation and maintenance
·The rotor accessory and package may be placed in the centrifugal chamber. You
should open the door lid for checking when installing.
·In the machine maintenance process, the parts that need remove cover may cause
electrical shock or personal injury. Ensure that the power has been cut off and the
power line has been removed from the socket, and qualified staff manipulates it.
·The replaced part must be consistent with the requirements of this centrifuge.
1.2 Attention for electric system
·To reduce the risk of electric shock, the centrifuge adopts the plug with three points
which must connect with the socket with ground lead.
·Make sure if the wall socket is connect with the ground wire. The voltage of power
supply must accord with the voltage of centrifuge.
·Don’t use the power adapter from three holes to two holes.
·It is forbidden to use the expanding socket with two lines or all-purpose power
adaptor without ground wire.
·Don’t put container with liquid on the centrifuge or around the centrifuge. If the
container is knocked over, the liquid will infiltrate into centrifuge and damage the
electrical or mechanical parts.
1.3 Attention for fireproofing
·Please use the overload fuse with same model and specification.
·The centrifuge is not designed for the flammable and explosive matters. You cannot
make centrifugation for the matters (chloroform, acetaldehyde), and cannot put the
matters in the centrifuge or store them around centrifuge within 30cm.

1.4 Attention for safe operation
·Please use the rotor and accessories which are designed for this centrifuge.
·Make sure if the centrifugal chamber is cleaned before operation.
·Make sure if the screw (nut) of the rotor in the centrifugal chamber has been screwed
down.
·Not exceed its max speed of rotor during operation.
·Don’t decelerate rotor speed or stop by hand.
·Don’t hold or move centrifuge when rotor is rotating.
·If the glass test tube is cracked in centrifuge chamber, please carefully check and
clean the gasket and centrifugal chamber because the glass fragment may have
inserted into their surface.
·Don’t open the door lid of centrifuge in the running status.
·The distance between centrifuge and other objects must be kept 30cm during
operation. You should not stand around centrifuge within 30cm unless adjusting it.
Anything is not allowed to enter into centrifuge during operation.
1.5 Attention for safety in chemistry and biology
· The routine manipulation may include all kinds of liquid and test sample which may
be the disease-causing and poisonous matters. The centrifuge can not be manipulated
with the matters unless you have toke the protection measures.
·Please pay attention to the liquid explanation in container before operation.
·Be careful of the infectious liquid. If not understanding the provided sample, please
at least make sure that they aren’t microbe. You must make further aerosol protection
（the suspended speck in the air, such as smoke and fog. ）for the easier
disease-causing hepatitis virus(B or C), HIV, atypical mycobacteria and the fungus of
physical structure.
·The infectious samples must be manipulated according to the manipulating program
and method in lab for avoiding expanding disease.
·The spilt matters may produce aerosol（the suspended speck in the air, such as smoke
and fog.）, so please pay attention to the warning about aerosol (the suspended speck

4
in the air, such as smoke and fog.)
·Only use the suitable rotor and adaptor. The centrifuge can not be manipulated with
disease-causing, poisonous or radioactive matters unless you have toke the protection
measures. When the second type of hazardous substances (according to “Laboratory
Biosafety Manual” of the World Health Organization.) is manipulated, the air safety
level must be monitored. The superior substances require a higher level of safe
protection measurements.
·You should follow the environment security and protection requirements when
destroying the discarded liquid.
