Rotor Installation, Loading and
Balancing
Install, load, and balance the rotor according to the instructions given
in the rotor instruction manual.
Normal Operation
Read the Safety Information Page at the front of this manual.
1 Check all OPTION LED indicators – if selection changes are
required, press MENU, then press ENTER to access each option
screen in succession (see figure 4-1 on page 4-7). As you step
through each screen, you may select or deselect, and change or
accept the previous setting. To check an existing selection setting
(Slow Start/Stop rates, Brake Off speed, Overtemperature Limit
or Step Run sequence), press 1 to display the option's secondary
screen, then view the displayed value. When finished with all
changes, press MENU to return to the HOME screen.

If maximum compartment
mass is exceeded, the maximum
speed must be lowered (see Reduc-
ing Speed for Rotor Compartment
Loads in Excess of Design Mass,
page 4-14). Failure to do so can cause
rotor failure which could result in per-
sonal injury or centrifuge damage.

1 Values reflect the centrifuge's calculation rounding, are based on the rotor's maximum radius, and do not consider any tube, bottle or adapter geometry.
2 Maximum allowable at maximum speed (see Reducing Speed for Rotor Compartment Loads in Excess of Design Mass, page 4-13).
3 Value includes the mass of the bucket, adapter (if used), blood bags or bottle, and sample; value for contents only (not including the bucket) is
2160 grams.
