2-5. Installation
To install the centrifuge:
1. Place the centrifuge on a sturdy bench or work table that will
support its weight, leaving space for sample preparation. Be
sure to leave a minimum clearance of 10 cm (4 inches) on all
sides for proper air circulation.
2. Make sure the centrifuge is level.
3. Make sure the centifuge is set for the proper voltage (see page
2-3, Voltage Selection).
4. Make sure the power switch is set to "O" (OFF position).
5. Insert the universal keyed end of the power cord into the power
connector at the back of the centrifuge and the other end into a
wall receptacle. The centrifuge is now ready for use.
2-6. Rotor Considerations
a. Rotor Temperature
Centrifugation creates an increase in rotor temperature. The increase
in temperature is caused by variables including rotor speed, length
of the run, and the type of rotor.
Air flow through the TC6 ® Centrifuge is designed to minimize the
increase in rotor temperature. Air enters through the air vent in the
front panel and exits through the fan vent located at the back of the
centrifuge.
When running temperature-sensitive material, a trial run is
recommended.
b. Rotor Installation, Loading and Balancing
Before placing the rotor on the drive spindle, make sure that there
are no loose objects inside the rotor chamber; for example, clips,
tubing, tape, or labels, and that the rotor centerhole and drive
spindle are clean and free of nicks and scratches. Wipe these surfaces
before each use.
Gently place the rotor body on the tapered spindle of the centrifuge,
aligning the shaft pin with the slots in the rotor. Secure the rotor to
the drive spindle by turning the rotor locking knob clockwise.
C A U T I O N
Do not lift the centrifuge by
the front panel or the chamber door.
To do so can result in damage to
these parts.
If the power cord is connected to the
wrong voltage, it can cause damage
to the centrifuge. Check the voltage
listed on the nameplate before
plugging the power cord into the
power source. Sorvall is not
responsible for incorrect installation.
Do not operate the centrifuge without
making sure the rotor is properly
balanced. Also, when installing a
rotor, carefully place it on the
centrifuge drive spindle. The
centrifuge spindle bearings can be
damaged if rotor is dropped on the
drive spindle.

W A R N I N G
Blocking the air flow enter-
ing and/or exiting the TC6 ® centri-
fuge will cause an increase in tem-
perature within the rotor chamber. The
temperature increase can temporarily
distort non-metal surfaces allowing
particles to exit the rotor chamber
resulting in personal injury and/or cen-
trifuge damage should tube break-
age or rotor failure occur.
When loading the rotor, be sure not
to exceed the maximum compartment
mass of the rotor (see the individual
rotor instruction manual). If maximum
compartment mass is exceeded,
maximum rotor speed must be
lowered as described in the rotor
instruction manual, Compartment
Loads in Excess of Design Mass.
Failure to do so can cause rotor failure
which could result in personal injury
and/or centrifuge damage.
