CHAPTER 3
Operating Instructions
Opening and Closing the Cover
The electrically operated cover interlock mechanism prevents operation until the cover is
completely closed and locked, and prevents the cover from being opened while the
centrifuge is in operation. When the cover is completely closed and locked, an operating
cycle can be initiated.
Cover Interlock By-pass
To release the electronically operated cover interlock mechanism, insert the manual latch
release tool into the small hole in the center of the front membrane panel. If you press the
Stop or Open button and the cover does not release, push the lock lever inward about one
inch (25 mm) to release the interlock mechanism. The cover interlock by-pass is for
emergency use only. Misuse may expose the operator to unsafe conditions.
Caution
The cover interlock bypass is for emergency use only. Disconnect the power cord
from the wall outlet and ensure the rotor has come to a complete stop before using
the interlock bypass. If the equipment is not used correctly, safety can be impaired.
Removing and Installing the Rotor
The Express 3 is shipped with the rotor installed and supported by a shipping retainer. To
prevent possible damage to the motor mount of the centrifuge, remove the rotor whenever
the centrifuge is shipped to another location.
Caution
Inspect rotor on a routine basis. Rotor lifespan depends on usage. Inspect rotor for
cracks and replace the rotor immediately when any crack or visible wear occurs.
Important
Before operating the centrifuge, ensure that retaining nut has been tightened
completely.
Removing the Rotor
1
Remove the tube inserts from the rotor.
2
Loosen and unscrew the retaining nut using the 5/16 inch hex key tool.
3
Remove the retaining nut and lift the rotor off the drive shaft.
