8.0 Service and Maintenance

8.1 Centrifuge Service

The brushless motor in this microcentrifuge requires no routine maintenance. Any required service should be performed by
authorized, qualified personnel only. Repairs performed by unauthorized personnel may void the warranty.

8.2 Cleaning

Always keep the centrifuge housing, rotor chamber, rotor and rotor accessories clean. All parts should be wiped down periodically
with a soft cloth. For more thorough cleaning, use a neutral cleaning agent (pH between 6 and 8) applied with a soft cloth. Excessive
amounts of liquid should be avoided. Liquid should not come into contact with the motor. After cleaning, ensure that all parts are
dried thoroughly by hand or in a warm air cabinet (maximum temperature 50°C).
The rotor should be cleaned after each use. When spinning samples containing phenol or phenol chloroform, the rotor should be
cleaned immediately after use.
Should a spill of infectious materials occur within the rotor or chamber, the unit should be disinfected. This should be performed by
qualified personnel with proper protective equipment.

8.3 Replacing Fuses

Check the fuse when it is recommended (see Troubleshooting Guide section). Disconnect the power cord from the wall socket before
checking the fuses. The fuse holder is located in the power inlet on the rear of the unit. Open the fuse holder drawer by inserting a
small screwdriver under the tab and prying it open. Remove the innermost (operative) fuse from its retaining tabs, and replace the
fuse if necessary. A spare fuse is located in the outermost chamber of the fuse drawer. Replace only with a fuse of exactly the same
value as the original. See Section 3.0 for information on fuse type.
