Electrical Safety
Electrical Safety
To reduce the risk of electrical shock, this equipment uses a three-wire electrical cord and plug to
connect this equipment to earth-ground. To preserve this safety feature:
• Make sure that the matching wall outlet receptacle is properly wired and earth-grounded.
Check that the line voltage agrees with the voltage listed on the name-rating plate affixed to
the instrument.
•
Never use a three-to-two wire plug adapter.
• Never use a two-wire extension cord or a two-wire non-grounding type of multiple-outlet
receptacle strip.
• Do not place containers holding liquid on or near the chamber door. If they spill, liquid may get
into the instrument and damage electrical or mechanical components.
• Work on the power supply system must be performed by certified electricians.
•
Inspect the electrical equipment of the unit regularly. Defects such as loose or burnt cables
must be eliminated immediately.
Safety Against Risk of Fire
This centrifuge is not designed for use with materials capable of developing flammable or explosive
vapors. Do not centrifuge such materials (such as chloroform or ethyl alcohol) in this centrifuge nor
handle or store them within the 30 cm (12 inches) clearance envelope surrounding the centrifuge.
Do not use the centrifuge within hazardous locations.
Mechanical Safety
For safe operation of the equipment, observe the following:
•
Use only the rotors and accessories designed for use in this centrifuge.
•
Before starting the centrifuge, make sure that the rotor tie-down screw is securely fastened.
•
Do not exceed the maximum rated speed of the rotor in use.
•
NEVER attempt to slow or stop the rotor by hand.
•
NEVER attempt to override the door interlock system while the rotor is spinning.
•
Maintain a 30 cm (12 inches) clearance envelope around the centrifuge while it is running.
During operation you should come within the envelope only to adjust instrument controls,
if necessary.
•
Never bring any flammable substances within the 30 cm (12 inches) area surrounding the
centrifuge.
•
Never operate the instrument without a rotor installed.
