If any problems are found during the initial setup procedure, refer to the troubleshooting section.
1. Plug the female end of the line cord into the back 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 power switch located on the back of the centrifuge to the ON position.
3. For operator safety, the locking system is always active; requiring power and direction from the
user to disengage it (the lid also automatically unlocks at the end of a run when it is safe to do
so). To unlock the lid (in order to access the rotor chamber) press the ‘OPEN / STOP’ button
on the control panel. The ‘UNLOCKED’ indicator light should illuminate. If it does not, refer to
the section on troubleshooting. The lid will remain unlocked for 15 seconds after pressing 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 the section on troubleshooting.
6. Place the buckets inside the rotor 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 properly and the ‘LATCHED’ indicator light is illuminated.
8. Use the up arrow button next to the RPM display to set the speed to full. The top speed for the
horizontal rotor is 3500 RPM (3200 RPM for fixed angle rotors).
9. Initiate a test run by pressing the ‘START’ button.
(Continued on next page)
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 21” 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 30” x 30”, (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 rest on its four rubber 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.

Guide to Balanced Centrifuge Loads
One to four devices can be processed in the same cycle. To ensure that the load is balanced, op-
posing buckets must be loaded with equally filled devices or a device and a counterbalance. Please
refer to device I.F.U. for proper use of the counterbalance.
1 device: Load the opposing bucket with a counter balance
2 devices: Place the two devices in opposite buckets
3 devices: Place a counter balance in the empty bucket
4 devices: Insure that devices in opposing bucket are filled identically

Care and Preventative Maintenance
With proper care and maintenance your HORIZON centrifuge will provide years of laboratory service.
For proper care, the following steps should be taken:
1. Provide Adequate Ventilation: For cooling purposes, the HORIZON draws in ambient air through
the air intake cover on the top of the lid and exhausts this air in the back of the base. The centrifuge
should be placed on a hard smooth surface for good air circulation.
2. Always Spin Balanced Loads: This centrifuge is equipped with imbalance detection. However, it is
still possible to run loads that are minimally imbalanced. Refer to page 8 for additional information on
balancing the load.
3. Keep the Buckets 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 bucket after a tube breakage may adhere to the next tube inserted in that
bucket. 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 bucket. Properly dispose
of the sample and tube fragments and thoroughly clean both the inside and outside of the bucket.
Insert a new tube cushion (if necessary) and replace the bucket in the rotor.
4. Motor and Electrical Maintenance: This centrifuge uses a brushless-DC motor. There are no
brushes to replace and it should not need routine servicing for the life of the centrifuge. The electrical
components are selected for high reliability and should not need service.
5. Keep the Centrifuge Clean: The cabinet, rotor top and accessories shall be thoroughly cleaned
using either soap and water, or a mild bleach solution. It is critical that the buckets are dried completely
inside before any product tubes are loaded. Left over chemical residue can damage or weaken the
tubes. 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 buckets and shall not be used.
If it is necessary to remove the rotor for additional cleaning it is required that a qualified technician remove
the outside housing and rotor assembly. Contact your authorized dealer for additional information.
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!
6. Bucket Replacement: It is recommended that the buckets be replaced after 24 months of use.
Inspect buckets regularly for cracks. If cracks are discovered, replace immediately.

(continued on next page)

Safety:
HORIZON Lid Safety Switch: The HORIZON 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. The yellow ‘LATCHED’ indicator light on the front of the machine
will illuminate when the lid has been latched properly.
HORIZON Lid Safety Interlock System: In addition to the Lid Safety Switch, the HORIZON has a
true “0 RPM” lid locking system. The lid safety interlock system keeps the lid locked at all times,
(even during power failure), and requires that the rotor be at rest in order to unlock the lid. 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.
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.
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 your authorized dealer for further information
or testing availability.
The HORIZON 24 Flex complies with all requirements of UL’s Electrical Equipment for Measurement,
Control, and Laboratory Use; Part 1: General Requirements, UL 61010-1, Issued: 7/12/2004, Ed: 2nd,
