In order to obtain properly centrifuged specimens and to prevent damage to the
machine, carefully observe the following basic operating precautions.
a. Electrical. Operate the Dynac II Centrifuge only from an ac power source
approved for each model.
b. Rotor Installation. Never attempt to operate the centrifuge without first
installing a complete rotor and shield assembly.
c. Zero Speed Setting. Before turning the centrifuge on, always turn the speed
control knob to "0."
d. Load Balancing. For smooth operation and long service life, tubes must be
placed in a balanced array.
e. Timing and Speed. For accurate results, follow the timing and speed specified
for the particular centrifugation procedure.
f. Cleanliness. Keep the centrifuge clean and dust-free in accordance with
maintenance and service instructions. Avoid spilling liquids into the centrifuge bowl. If the
interior of the centrifuge contains dust, glass particles, or other foreign matter, it is possible
for these contaminants to be stirred into the air and deposited into specimen tubes. Keep
the centrifuge interior clean to prevent contamination of samples.
Basic safety precautions must be observed when operating the centrifuge in order
to avoid the hazards of electrical shock or other physical injury.
a. The Dynac II Centrifuge is not to be used in a Class I, Division 1, Group C
hazardous location defined by the National Fire Protection Association, Bulletin No. 56A
(Inhalation Anesthetics), as extending upward to a level of five feet above the floor where
flammable anesthetics are used.
b. To avoid electrical shock, follow these procedures:
Plug the power cord only into a grounded 3-wire receptacle.
Never remove the grounding prong from the power plug.
Always unplug the power cord before attempting to service the centrifuge.
(4) Immediately have a worn or damaged power cord or plug replaced by an
