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 bench top clearance height of 20” is required in order 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”, (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 ow.
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 at and level.
e) Be sure the outlet is always within reach as the line cord is the
means of emergency disconnection!

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, ll a tube with water to
match the weight of the unpaired sample and place it across from
this sample.

6. Tube Holder Replacement: It is recommended that the tube holders be
replaced after 24 months of use.
Operation:
7. 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.
Safety:
Lid Safety Switch: The 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.
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.
The Model 614B complies with all requirements of UL standard
61010A-1, 61010A-2-20; Can/CSA C22.2 No’s 1010.1; 1010.2.20.
Calibration and Earth Ground Testing:
It is recommended that the top speed, ground continuity and line leakage be tested
every two years for continued safe operation. Contact The Drucker Company for
further information or testing availability.
NOTE:
The latch must be turned completely
Troubleshooting:
1. Problem:
Solutions: – Make sure nothing has fallen into the rotor chamber.
2. Problem: Excessive noise when the machine is running.
Solutions: – Check to see that the load is balanced.
3. Problem: The centrifuge does not run.
Solutions: – Check the electrical outlet.
The rotor does not spin freely.
– If there is nothing obstructing the rotor, contact The Drucker
Company for further assistance.
– Make sure that nothing has fallen into the rotor chamber.
– Make sure that the nut in the center of the rotor is tight.
– Have a technician test the motor and replace it if necessary.
– Make sure the lid latch is turned completely clockwise to its stop
position.
– Check the circuit breaker switch at the bottom left of the machine.
If the switch is white, the breaker has tripped. Contact The
Drucker Company for further assistance.

rules for balanced loads.
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.
7. The centrifuge should begin to spin.
8. 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.
9. Turn the lid knob counter–clockwise and open the lid.
10. Remove the samples.
11. The centrifuge is immediately ready for operation.
Rotor Removal and Installation:
To remove the rotor:
CAUTION: Unplug the centrifuge from the electrical outlet at this time to
eliminate the possibility of electrical shock or other injury.
1. Open the lid.
2. Remove the test tube holders.
3. Remove the knob or nut in the center of the rotor by turning it
counter-clockwise. A nut driver 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 t has been achieved, replace the rotor knob or nut and
turn it until it is hand-tight.
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.

Tube Holder Congurations:
The xed-angle rotor that came with your Model 614B is capable of spinning test tubes
up to 17 mm x 125 mm. Use the following chart and drawing to determine which tube
holder and cushion combination should be used with your application.
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:
DIRECTIONS:
1. Compare the tube to be spun with the four boxes shown below.
2. Find the box that most closely matches the tube’s length. NOTE: The
tube length with its stopper or cap must be shorter then the chosen
box or the tube will not t properly in the tube holder.
3. Match the letter from the chosen box with one of the congurations shown.
For Example: A tube is found to be as long as box B. Accordingly, we can

1. Provide Adequate Ventilation: For cooling purposes, the centrifuge 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 4 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
ngers 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
A/C motor. It should not need servicig for the life of the centrifuge. The electrical
components are selected for high reliability and should not need service.
5. Keep the Rotor Chamber Clean: Every six months, or whenever there is a
tube breakage, (refer to the note in #3), it may be necessary to remove the
rotor and clean the rotor chamber. Follow the instructions on page 5 to
remove and re–install the rotor.
CAUTION: Before cleaning, always unplug the line cord from the electrical
outlet to eliminate the risk of electric shock.
The rotor chamber, rotor and accessories should be thoroughly cleaned
using either isopropyl alcohol, soap and water, or bleach. The use of Fully/
Partially Halogenated Hydrocarbons, Ketones, Esters and all other
chemicals not prescribed by the manufacturer may cause damage to the
rotor and tube holders and should not be used. 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 your warranty!
