Model Description:
The Horizon Models 642VES, 642VFD, and 642VFD-Plus are continuous-duty, electronically
controlled, variable-speed, laboratory centrifuges equipped with a lid safety interlock system.
They offer the user control over many parameters, including variable runtime, speed control, and
deceleration. The exclusive horizontal rotor allows for quick and easy sample loading and complete
horizontal separation. Samples can be viewed safely through the transparent lid. Entry into the
centrifuge is restricted during operation by the safety interlock system.
The centrifuge is controlled in the following manner depending on the model:
642VES: Controlled by five electronic push buttons and a backlit display, for easily controlling
centrifugation parameters. Up to nine commonly used settings can be saved and recalled at
the touch of a button.
642VFD-Plus:Controlled by two electronic push-button timers that have been preset for ten (10)
minutes at 3,800 RPM and five (5) minutes at 1,800 RPM, for precise spin times and
ease of use.
642VFD: Controlled by one electronic push-button timer that has been preset for ten (10)
minutes at 3,800 RPM, for precise spin times and ease of use.
WARNING: Use universal precautions when
handling laboratory specimens. All human
specimens of blood, blood compounds, or
bodily uids are potentially biohazardous and
may contain Hepatitis B virus, Hepatitis C
virus, Human immunodeciency virus or other
disease causing agents. For the safety of both
the operator and service personnel, care should
be taken when handling substances that are
known to be toxic, radioactive, or contaminated
with pathogenic microorganisms when using
this centrifuge. When Risk Group II materials
are used (as identied in the World Health
Organization “Laboratory Bio-Safety Manual”)
the use of a Bio-Seal should be employed. More
than one level of protection must be provided in
the case of materials of a higher group. The use
of ammable or explosive materials as well as
those materials which chemically react vigorously
is prohibited. Any use of the equipment in a
manner not specied in these instructions may
impair the level of protection provided by the
equipent.

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). Do not position the centrifuge in such a way
that it would be difcult to disconnect the power in the case of emergency. 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!
Initial Setup Procedure:
If any problems are found during the initial setup procedure, refer to the troubleshooting
section on page 9.
1. Plug the female end of the supplied line cord into the power input module located on the
rear of the centrifuge. Plug the male end into an approved
electrical outlet. For electrical safety, the unit must always be
properly grounded.
2. Flip the switch on the power input module located on the rear ofthe
centrifuge to the ON ( | ) position.
3. For safety purposes, the locking system is always activated. To
deactivate the system, (in order to insert or retrieve samples),
press the OPEN/STOP button on the
control panel. The UNLOCKED indicator light should illuminate. If it does not,
refer to page 9 on troubleshooting. The lid will be unlocked for 15 seconds after pushing
the OPEN/STOP button.
4. Turn the latch counterclockwise and open the lid.
5. Spin the rotor by hand; check for free and level rotation. If the rotor does not spin freely,
refer to page 9 on troubleshooting.
6. Place the six test tube holders inside the rotor (as shown to the right), and verify that
they are seated properly.
7. Close the lid. Rotate the lid knob clockwise to its complete stop position. The ’LATCHED’
indicator light should be illuminated. If it is not, make sure that the lid is latched properly.
The centrifuge will not run unless the lid is latched and the ‘LATCHED’ light is
illuminated.
8. Start a centrifugation cycle by pushing the START (BLOOD) button.
9. The ‘RUNNING’ indicator light will illuminate.
10.The test tube holders will slide up into the horizontal position and the unit will accelerate
to full speed.
11.Listen to the sound of the centrifuge. A smooth whirring sound should be heard. If
there are any loud or unusual sounds, stop the centrifuge by pushing the OPEN/STOP
button immediately and refer to page 9 on troubleshooting.
12.Push the OPEN/STOP button. The ‘RUNNING’ indicator light should go out and the
motor should slow to a stop.
12.The lid should remain locked until the rotor has nearly stopped. If the machine unlocks
prematurely, contact Drucker Diagnostics for assistance. Once the rotor has stopped, the
interlock system will become disengaged for sixty (60) seconds. The ‘UNLOCKED’
indicator light will illuminate during this time.
13.To gain entry into the centrifuge after this period has ended, simply press the OPEN/
STOP button. The lid will unlock for fteen (15) additional seconds.
After the centrifuge has passed this procedure it is ready for operation.
