Your centrifuge must contain a balanced load in order to work properly.
Spinning balanced loads will extend the life of the machine and
1.
Opposing tube holders must be identical and must contain the same
cushion, or none at all.
2.
Opposing tube holders must be empty or loaded with equally
weighted samples.
3.
If an odd number of samples is to be spun, fill a tube with water to
match the weight of the unpaired sample and place it across from this sample.
Rotor Removal, Installation, and Selection:
To remove the rotor:
1. Unlock the centrifuge by pushing the OPEN/STOP button and unlatch and open the lid.
CAUTION: Unplug the centrifuge from the electrical outlet at this time to eliminate the possibility
of electrical shock or other injury.
2. Remove the test tube holders.
3. Remove the nut in the center of the rotor by turning it counterclockwise, (a 1/2" nut driver may be
required).
4. The rotor is sitting on a cone-shaped adapter. Pull the rotor up and off of this adapter.
To install the rotor:
1.
Place the rotor back onto the cone-shaped adapter. You may need to turn the rotor slightly to
line it up properly.
2.
The rotor should slide onto the rotor cone freely.
3.
Once a proper fit has been achieved, replace the rotor knob or nut and turn it until it is hand-
tight.
4.
Replace the tube holders and verify that they are seated properly.
5.
It is recommended that the initial setup procedures be performed to ensure that the rotor has
been installed correctly and that no damage has been done to the centrifuge during either the
rotor installation or possible rotor chamber cleaning. See page 4 for this procedure.
To select a rotor:
Follow these steps when installing a different rotor type than what was previously installed:
Programming the Rotor Selection
1.
Power off the centrifuge.
2.
Press and hold the START (START 1 for VFD-Plus) and OPEN/STOP buttons while powering
the centrifuge on.
3.
Once the centrifuge has powered on, release the two buttons.
4.
All LEDs should light up signaling that the rotor selection mode has been entered.
5.
To select the fixed angle rotor press the START (START 1 for VFD-Plus) once.
6.
To select the horizontal rotor press the START (START 1 for VFD-Plus) twice.
7.
Press the OPEN/STOP button once to save the setting.
8.
The centrifuge will then beep once or twice indicating the rotor selection that was just entered.
a. VES only: will display either 'Fixed' or 'Horiz' to indicate the selected rotor.
Verifying the Rotor Selection
1.
Power off the centrifuge.
2.
Press and hold OPEN/STOP.
3.
While continuing to hold this buttons power the centrifuge on.
4.
Release the OPEN/STOP button.
5.
The centrifuge will then beep once or twice indicating the rotor selection.
a. VES only: will display either 'Fixed' or 'Horiz' to indicate the selected rotor.
BALANCED LOADS
Use the following rules when loading the rotor.
