Operating Instructions
Opening and Closing the Cover
An electronic operated cover interlock mechanism prevents operation if the cover is not completely
closed and locked, and prevents the cover from opening when the rotor is turning. An operating
cycle can be initiated only if the cover latch is engaged.
Cover Interlock By-pass
In case of power failure or malfunction, the Stop/Open button may not release the cover. To recover
samples in the rotor, the cover interlock mechanism can be released manually by inserting the
manual latch release tool supplied with the instrument into the small hole located in the front of the
housing. Push the tool inward about one inch (25 mm) to release the latch.
CAUTION - The cover interlock by-pass is for emergency use only. Misuse may
expose the operator to unsafe conditions.
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 centrifuge’s motor mount, it is important to remove the rotor whenever the
centrifuge is moved or shipped to another location.
CAUTION - The rotor (RTX8) has a finite lifespan that is dependant on usage.
Cracks or swelling are signs of fatigue, replace immediately.
Before operating the centrifuge, ensure that retaining nut has been tightened completely.
To remove 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.
To re-install rotor:
Note that there are two drive pins adjacent to the drive shaft on the rotor mount. These pins mate
with the corresponding holes on the bottom of the rotor.
1. Rotate the rotor so that wells 5 and 6 are aligned with the drive pins.
