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 6 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 642E 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 642E
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 10 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.
4. Motor and Electrical Maintenance: The Model 642E 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.
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.

Drucker Diagnostics – Customer Service: [phone] – [e-mail] | Page 9
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 8
to remove and reinstall the rotor.
TROUBLESHOOTING
Note: The latch must be turned completely clockwise to its stop position in order for the centrifuge to operate.
Problem: The rotor does not spin freely.
Solution:
o Make sure nothing has fallen into the rotor chamber
o If there is nothing obstructing the rotor, the rotor may be damaged. Contact Drucker Diagnostics for
further assistance.
Problem: Excessive noise when the machine is running.
Solution:
o Check to see that the load is balanced.
o Make sure that nothing has fallen into the rotor chamber.
o Make sure that the nut in the center of the rotor is tight.
o Have a technician test the motor and replace it if necessary.
Problem: The Centrifuge does not spin.
Solution:
o Check the electrical outlet
o Make sure the lid latch is turned completely clockwise to its stop position. When the lid is closed properly,
the latch light on the control panel will illuminate.
o Check the circuit breaker switch at the bottom left of the machine. If the switch is white, the breaker has
tripped. Contact Drucker Diagnostics for further assistance.
o The printed circuit board may be damage. Have a technician test and replace the circuit board if
necessary.
Problem: The latch light does not come on when the lid is closed.
Solution:
o Make sure that the unit has power.
o Make sure the lid latch is turned completely clockwise to its stop position. The latch makes contact with a
switch underneath the front top of the cabinet. If this switch is not activated. The light will not tur on the
machine will not run

Drucker Diagnostics – Customer Service: [phone] – [e-mail] | Page 10
Problem: The machine does not unlock after a run has completed.
Solution: The lid should remain locked until the rotor has nearly come to a complete stop and then unlock for 60
seconds. If additional unlock time is needed, press the ‘OPEN / STOP’ button with the machine plugged in and the
rotor stopped. If the lid remains locked after this and will not unlock, the electronics may have been damaged.
Contact Drucker Diagnostics for further assistance. To access the rotor chamber, follow the procedure on Page 14,
“Emergency Rotor Chamber Entry”.
Problem: The run time is not set to the desired length.
Solution: Check the run preset by following the instructions on page 8. If the preset is not the desired length,
follow the procedure on the same page to change the run preset time.
EMERGENCY ROTOR CHAMBER ENTRY
In the event of power failure, it may be impossible to unlock the lid by conventional means. In this case, entry into
the rotor chamber may be made by removing the latch label and using a pen to manually disengage the locking
mechanism (see photo). Pull the mechanism towards the control panel and then
unlatch and open the lid. If the unit is damaged, contact your authorized dealer or
Drucker Diagnostics.
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 642E complies with US, Canadian, and European Safety standards.
Lid Safety Switch: The Model 642E 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. An indicator light on the front of the machine will
light up when the lid has been latched properly.
Lid Safety Interlock System: In addition to the Lid Safety Switch, the Model 642E has a true “0 RPM” lid locking
system. The lid safety locking system keeps the lid locked at all times when the rotor is in motion (even during
power failure). The centrifuge will not allow entry into the rotor chamber unless the centrifuge has power and the
rotor is stopped. To open the lid, make sure that the centrifuge is plugged in and, with the rotor stopped, press the
‘OPEN / STOP’ button.
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,
but the lid will still remain locked. 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 642E 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.

DESCRIPTION DU MODÈLE
Le modèle 642E est une centrifugeuse horizontale à commande électronique à fonctionnement continu avec un
système de verrouillage de sécurité du couvercle. L'appareil est contrôlée par une minuterie électronique à
bouton-poussoir qui a été préréglée pendant dix (10) minutes, pour des durées de rotation précises et une facilité
d'utilisation. Vous pouvez visualiser les échantillons en toute sécurité à travers le couvercle transparent. Pendant
le fonctionnement, le système de verrouillage de sécurité limite l'entrée dans la machine. Le modèle 642E dispose
d'un panneau de commande éclairé qui affiche l'état de la machine, facilement visible à distance.
Cette centrifugeuse de laboratoire à usage général est conçue pour faire fonctionner également d’autres récipients
approuvés remplis de produits chimiques (ininflammables, non explosifs, non volatils et non hautement réactifs
uniquement) et des échantillons environnementaux

EMPLACEMENT INSTALLATION
1. Déballez la centrifugeuse et vérifiez que tout l'équipement fourni est présent.
2. Sélectionnez un emplacement de configuration qui répond aux critères suivants :
a. Une hauteur intérieure de 20 po (50,8 cm) est nécessaire pour ouvrir le couvercle.
b. L'enveloppe de dégagement est l'espace autour de la centrifugeuse qui est requis pour la
sécurité. Sélectionnez un emplacement de configuration qui permettra une enveloppe de
dégagement d'au moins 24po x 24 po (avec la centrifugeuse au centre). Aucune personne ou
matière dangereuse ne doit être autorisée dans l'enveloppe de dégagement pendant le
fonctionnement. La durée passé par l’utilisateur à l’intérieur de l’enveloppe doit être limité au
durée nécessaire au chargement, au déchargement et au fonctionnement de la centrifugeuse
uniquement.
c. Une ventilation adéquate est nécessaire pour éviter la surchauffe des échantillons ainsi que la
défaillance prématurée de la centrifugeuse. Choisissez un endroit qui permet une circulation
libre de l’air et où la température demeure entre et °C.
d. La centrifugeuse est conçue pour être fixée à la surface de fonctionnement par quatre pieds-
ventouse. Aucun réglage n'est nécessaire pour niveler la centrifugeuse ; cependant, la surface
doit être plane et horizontale.
e. Assurez-vous que la prise est toujours à portée de main car le cordon d'alimentation est le
moyen de déconnexion d'urgence !
