2. 3. Open/Close the Centrifuge Lid
To open the centrifuge lid:
Press the Lid Open button on the home screen or
Open
on the LCD control panel.
A WARNING Do not use the mechanical emergency door release as regular procedure to open the
centrifuge. Use the mechanical emergency door release only if a malfunction or power failure occurs and only
when you have made sure that the rotor has stopped spinning (see
“Mechanical Emergency Door Release”
on page 6-1 ).
To close the centrifuge lid:
Close the centrifuge lid by pressing down on it lightly in the middle or on both sides. The locking mechanism
engages to close the lid safely. The lid should audibly click into place.
Double-check whether the locking mechanism has engaged properly.
A WARNING Do not reach into the gap between the lid and the casing. The lid is drawn shut automatically
and may pinch your fingers.
2. 4. How to Install and Remove a Rotor
To install a rotor:
1. Press the Open button on the home screen or
Open
on the control panel to open the lid of the centrifuge.
2. Place the rotor over the drive shaft and let it slide down slowly.
The rotor clicks into place automatically.
A CAUTION Do not force the rotor onto the drive shaft. If the rotor is very light, it may be necessary to
carefully press it onto the drive shaft with little force.
3. Make sure that the rotor is properly installed by lifting it slightly on the handle. If the rotor can be pulled up,
then it must be reclamped to the drive shaft.
A WARNING If the rotor cannot be properly locked in place after several attempts, then the Auto-Lock
is defective and you are not permitted to operate the rotor. Check for any damage to the rotor: Damaged
rotors must not be used. Keep the drive shaft area of the rotor clear of objects.
A CAUTION Make sure that the rotor is properly locked on the drive shaft before each use by pulling
at its handle.
4. Make sure the rotor spins freely by turning it manually.
5. Swing out rotors only: make sure that a full complement of buckets is installed before operating the rotor.
