WARNING
Spin balanced loads only!
Do not place the tubes asymmetrically nor load unequal volume tubes. Improper place-
ment of tubes will lead to insufficient centrifugation and may cause serious injury or an
accident.
Balancing the Rotor
Tubes of equal weight and size should be placed opposite each other. Use additional sample
or water in other tubes to provide a balanced rotor. Examples of proper sample balancing are
illustrated next.
Resolution
• Verify that the AC adapter is fully plugged into the wall and
rear of unit.
• Verify that the power switch is turned on.
• Turn off the unit, wait 2 minutes, and turn power on.
• Inspect the tubes for equal fill or improper placement.
• Inspect the rotor for improper installation.
• Remove the tubes and determine if the noise persists with an
empty rotor.
• Verify that nothing is blocking the lid from fully closing.
• Verify that nothing has fallen into the lock mechanism open-
ing.
If for any reason you need to manually open the lid to access tubes
due to an error or power loss, please perform the below:
• Turn off the unit, remove power cord.
• Make sure the rotor has stopped completely.
• Use a thin rod and insert it into the opening on the bottom.
• Press gently but firmly. You will feel a mechanical movement
within the unit and the lid will release.
• Remove the rod, set the unit on the feet.
• Remove your tubes and reclose the lid.
