SETUP LOCATION
1. Unpack the centrifuge and verify that all of the supplied
equipment is present.
2. Choose a setup location which meets the following criteria:
a. A clearance height of 20” (50.8cm) is required to open the
lid.
b. The clearance envelope is the space around the centrifuge
which is required for safety. Choose a setup location which
will allow for a clearance envelope of at least 24” x 24”
(60.96cm x 60.96cm), (with the centrifuge at the center). No
person or hazardous material shall be permitted in the
clearance envelope during operation. The operator time
within the envelope shall be limited to the time necessary
for loading, unloading and centrifuge operation only.
c. Proper ventilation is necessary to prevent the overheating of
samples as well as premature failure of the centrifuge.
Choose an area which will allow unencumbered air flow.
d. The centrifuge is designed to secure to the operating surface
by four suction feet. No adjustment is necessary for leveling
the centrifuge, however, the surface should be flat and level.
e. Be sure the outlet is always within reach as the line cord is
the means of emergency disconnection!

OPERATION
NOTE: Follow the initial setup procedure on page 4 before initial operation.
1. Plug the centrifuge into an approved 115 Volt A.C., 60 Hz. outlet.
2. Turn the latch counterclockwise and open the lid.
3. Insert cushions (if needed) into the tube holders for the tube size
you are using.
4. Place the test tube samples into the tube holders. Be sure to
follow the rules for balanced loads (page 5).
5. Close the lid and turn the lid knob clockwise to its complete stop
position.
6. Turn on the machine by turning the timer to the desired run
time. The centrifuge should begin to spin.
7. Once the timer reaches zero (0), power will be cut to the motor
and the rotor will coast to a stop. Do not open the lid until the
rotor has come to a complete stop.
8. Turn the lid knob counterclockwise and open the lid.
9. Remove the samples.
10. The centrifuge is immediately ready for operation..
SPINNING BALANCED LOADS
Your centrifuge must contain a balanced load in order to work properly.
Use the following rules when loading the rotor.
Spinning balanced loads will extend the life of the machine and produce
better results.
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 AND INSTALLATION
TO REMOVE THE ROTOR:
1. Open the lid.
CAUTION: Unplug the centrifuge from the electrical outlet 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 tool 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 nut and turn it
until it is hand-tight, (a tool may be required).
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.

CARE AND PREVENTATIVE MAINTENANCE
With proper care and maintenance your centrifuge will provide years of
laboratory service. For proper care, the following steps should be taken:
1. Provide Adequate Ventilation: For cooling purposes, the Model
614B draws in ambient air through the air intake cover on the
top of the lid and exhausts this air in the rear of the base. The
centrifuge should be placed on a hard smooth surface for good
air circulation.
2. Always Spin Balanced Loads: Make certain that you are always
spinning a balanced load. The Model 614B has a unique counter
balanced motor mounting design which, along with its rubber
suction feet, produces excellent vibration dampening. However,
out–of–balance loads may break glass test tubes and may
produce unsatisfactory separation results. Proper load balancing
will improve sample separation and extend the life of the
centrifuge. Refer to page 5 on balanced loads for additional
information on balancing the load.
3. Keep the Tube Holders Clean: NOTE: Always follow the safety
guidelines of your laboratory to properly clean up and/or dispose
of materials in the event that a substance known to be
potentially toxic, radioactive or contaminated with a pathogenic
microorganism is spilt in or on the centrifuge. Small glass
fragments left in the tube holder after a tube breakage may
adhere to the next test tube inserted in that holder. When this
tube is handled, these fragments may puncture protective gloves
and lacerate the operator’s fingers or hand. Remaining fragments
may provide stress points on subsequent tubes and result in
additional breakage. If a tube breakage occurs, carefully remove
the tube holder. Properly dispose of the sample and tube
fragments and thoroughly clean both the inside and outside of
the tube holder. Insert a new tube cushion (if necessary) and
replace the tube holder in the rotor.
4. Motor and Electrical Maintenance: The Model 614B uses a
brushless permanent split capacitor AC motor. It should not need
routine servicing for the life of the centrifuge. The electrical
components are selected for high reliability and should not need
routine service.
5. Tube Holder Replacement: It is recommended that the tube
holders be replaced after 24 months of use. Inspect tube holders
regularly for cracks. If cracks are discovered, replace
immediately.

Drucker Diagnostics [phone] - [e-mail] Page | 8
6. Remove Accessories Before Moving: All tube holders, samples,
and caps must be removed from the rotor chamber before
transporting or storing the centrifuge to prevent damage and
injury.
CLEANING AND DISINFECTION
To prolong the life of the centrifuge cleaning and disinfection is
recommended every six months, or whenever there is a spillage or tube
breakage. Contaminants must be removed immediately, or corrosion and
premature degradation of components can occur.
1. Unplug the centrifuge before cleaning.
2. Apply cleaning solutions with a towel or cloth. Do not submerge
the centrifuge in water or other cleaning solutions as this will
cause damage and void the warranty.
3. ONLY isopropyl alcohol, soap and water, or a 10% (5500 PPM)
bleach solution should be used for cleaning and disinfection of
the centrifuge and accessories.
4. All surfaces must be dried immediately after cleaning and
disinfecting.
5. TBQ Germicidal products shall not be used, as they will cause
damage to the centrifuge and void the warranty.
6. The use of fully/partially halogenated hydrocarbons, ketones,
esters, ethers, benzyls, ethyl benzenes, and all other chemicals
not prescribed by the manufacturer shall not be used as they
may cause damage to the rotor chamber, rotor, tube holders,
accessories and centrifuge exterior and void the warranty.
7. It may be necessary to remove the rotor and clean the rotor
chamber. Follow the instructions on page 6 to remove and
reinstall the rotor.

CALIBRATION TESTING
It is recommended that the top speed be tested every two years for
continued safe operation. Contact Drucker Diagnostics for further
information or testing availability.
SAFETY
The Model 614B complies with US, Canadian, and European Safety standards.
Lid Safety Switch: The Model 614B lid is secured to the top of the cabinet
by a latching knob and pawl system. When the knob is rotated clockwise,
the pawl grips the underside of the cabinet opening and prevents the lid
from opening. A mechanical stop positions the pawl and prevents it from
rotating completely. When rotated to the stop position, the pawl makes
contact with a micro–switch mounted underneath the cabinet top. The lid
safety switch prevents the centrifuge from operating while the lid is open.
Note: After the centrifuge has started spinning, it may be possible
to rotate the lid knob enough to cause the pawl to lose contact
with the lid safety switch. If this happens, the centrifuge motor
may lose power. If the knob is accidentally moved and this
situation should occur, rotate the knob fully clockwise to its stop
position and the centrifuge will resume operation.
Circuit Breaker: The Model 614B is protected with a 4 Amp circuit breaker
located at the rear of the machine mounted to the base. Any electrical
short circuit will cause the breaker to cut power to the machine.
