7.6 Selection of Operating Time, Momentary Operation, Start/Stop
Operating time can be selected from 0.5 min to 99 min by pressing the TIME button and adjusting with
the control knob. The time can be set in 0.5 minute increments from 0 to 10 minutes and in 1 minute
increments from 10 to 99 minutes. After 99 minutes, the display shows “--” which indicates continuous
run. In this mode, the centrifuge will run until manually stopped. To start a run, press the control knob.
When the preselected time expires, the centrifuge will stop automatically. To stop the centrifuge prior
to the expiration of set time, press the control knob. The centrifuge may be operated for a short run by
pressing and holding the control knob. The centrifuge will continue to run as long as the control knob is
depressed and the time, in seconds will count up on the time display.
8.0 Service and Maintenance
8.1 Centrifuge Service
The brushless motor in the Prism™ 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 in the Troubleshooting Guide located in this manual. The fuse
holder is located in the power inlet on the rear of the unit. Disconnect the power cord from the power
inlet. 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. Fuse type may be found in the Technical data section of this manual.
