ROTOR CONFIGURATIONS:
1. Opposing tube carriers must be identical.
2. Opposing tube carriers must be empty or loaded with an equal number of
equally weighted samples.
3. If an odd number of samples is to be spun, use a water-lled tube to mate
with the unpaired one.
Your centrifuge must contain a balanced load in order
to work properly. To ensure that the load is balanced,
keep these rules in mind when inserting test tube
samples into the four (6) position horizontal rotor:
This rotor is designed to hold up to 6 tube carriers.
Follow the procedure below for proper tube loading.
page 8
1. Opposing tube carriers must be identical.
2. Opposing tube carriers must be empty or loaded with an equal number of
equally weighted samples.
3. If an odd number of samples is to be spun,
use a water-lled tube to mate with
the unpaired one.
NOTE: Do not load more than two (2) tubes per carrier if the tubes are greater than
100mm long (15mL). When loading these tubes into the carriers, place them all
on either side. For example, to load twelve (12) 15mL tubes, place two tubes on
the right-hand side of each carrier.
WARNING: When using glass test tubes, place a 7mm cushion at the bottom of each
location in the carriers. Failure to do so may result in damage to the test tube.
Six (6) Place 50mL Fixed-angle Rotor (optional):
Your centrifuge must contain a balanced load in order to
work properly. To ensure that the load is balanced, keep
these rules in mind when inserting test tube samples into
the 6 place, 50mL xed-angle rotor:
1. Opposing tube holders must be identical.
2. Opposing tube holders must be empty or loaded equally weighted samples.
3. If an odd number of samples is to be spun, use a water-lled tube to mate
with the unpaired one.
4. (Four Position Carriers Only):
When loading tubes into opposing
carriers, the carriers will be
balanced when the tubes are loaded
diagonally from one another
(not across from one another).
For example: six tubes are to be loaded
into two carriers. In each carrier, two tubes
are placed in the bottom and one tube is
placed in the upper left-hand position.

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 rear 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 on
balanced loads for additional information on balancing the load.
3. Keep the Tube Carriers / 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 pathogenetic
microorganism is spilt in or on the centrifuge. Small glass fragments left in the tube carrier
/ holder after a tube breakage may adhere to the next test tube inserted in that carrier /
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 carrier / holder. Insert a new tube
  cushion(ifnecessary)andreplacethetubecarrier/holder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 isopropyl alcohol, soap and water, or a mild bleach solution. 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 carriers / holders
and should not be used.
  Ifitisnecessarytoremovetherotorforadditionalcleaningitisrequiredthataqualied 
technician remove the outside housing and rotor assembly. Contact Woodley Equipment
Company 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. Tube Carrier / Holder Replacement: Tube carriers are stamped with an expiration date and
should be replaced according to this stamp.

TROUBLESHOOTING:
1. Problem: The rotor does not spin freely.
Solutions: • Make sure that nothing has fallen into the rotor chamber.
• If there is nothing obstructing the rotor, the motor may be damaged.
Contact your authorized dealer or Woodley Equipment Company for further
assistance.
2. Problem: There is excessive noise when the machine is running.
Solutions: • Check to see that the load is balanced.
• Make sure that nothing has fallen into the rotor chamber.
• Make sure that the screw in the center of the rotor is snug.
• The motor may be damaged. Contact your authorized dealer or
Woodley Equipment Company for further assistance.
3. Problem: The centrifuge does not run or an error message is displayed.
Solutions: • Make sure that the centrifuge is getting power. Do the control panel
displays come on? Check the electrical outlet that the unit is plugged into.
Check the circuit breaker on the base near the rear of the centrifuge.
• If the unit is getting power, make sure that the lid latch is closed properly.
   Thelatchisclosedproperlywhentheyellow‘LOCKED’indicatorlightis 
illuminated.
   •Ifthecentrifugestopssoonafterstart-upand‘ERROR’isdisplayedonthe 
speed display, refer to the following table for fault information:
ERROR / SPEED
The centrifuge cannot reach full speed due to a problem with the rotor, an
inadequate power supply, or other electrical problems. Press the OPEN/
STOP button to cancel the error and then check the rotor and the line
voltage. Contact your authorized dealer or Woodley Equipment Company for
further assistance.
ERROR / BALANC
The centrifuge has detected an imbalance. Press the OPEN/STOP button to
cancel the error and balance the load. If the load is balanced, make sure
that the centrifuge is installed on a secure, level location.
4. Problem: The lid knob cannot be turned / the lid cannot be unlocked.
Solutions: • Make sure the centrifuge has power and that the rotor is stopped. Press the
   ‘OPEN/STOP’button.Thered‘UNLOCKED’indicatorlightshouldilluminate 
and the unlocked mechanism should disengage, allowing entry into the
rotor chamber.

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‘LOCKED’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/EMERGENCY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Horizon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.
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 Woodley Equipment Company. for further information
or testing availability.
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 Woodley Equipment Company.
