Important safety reminder
Thermo Scientific WX Ultra Series v
WARNING
• 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 contamination 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.
• Never use any materials capable of producing flammable or explosive vapors, or
extreme exothermic reactions.
• The centrifuge is equipped with a three-wire power cord that has one wire for
connection to ground. The centrifuge must be correctly grounded to guard against
shock hazards.
CAUTION
• Do not operate the control keys using a ball-point pen or a sharp object.
• Do not run or precool the rotor at the critical speed as this will have a detrimental
effect on centrifuge component life (see rotor manual).
• Do not operate the centrifuge with a rotor that is not balanced within specification.
To do so can cause damage to the centrifuge drive assembly.
• Always make sure the rotor is correctly assembled and properly seated on the
centrifuge drive spindle before operation. If using a swinging-bucket rotor, always
make sure that a bucket is installed at each position and that each is properly seated
and can swing freely after installing the rotor on the centrifuge drive spindle (see rotor
manual).
• Do not exceed the maximum speed of the tubes, bottles, or adapters being used.
Check manufacturer's published specifications or see Sorvall Product Guide; if unsure,
to avoid loss of valuable sample, we recommend performing a test run.
• Do not continue to operate the centrifuge if abnormal sounds occur during operation.
Immediately discontinue use of the centrifuge and contact Thermo Service.
• Supply power must be checked before the centrifuge is connected to power because
the centrifuge can be damaged if connected to the wrong voltage. Thermo is not
responsible for incorrect installation and warranty is void if an initial installation or
electrical modification of the centrifuge is not performed by Thermo or a Thermo
representative.
• Before moving the centrifuge, always remove the rotor from the rotor chamber to
avoid damage to the drive assembly.
• Do not place fluids inside, on top of, or close to the centrifuge --- spillage can result in
electrical or mechanical failure.
• Always operate and maintain the centrifuge and all rotors as instructed in this manual
and in the rotor manual(s).
