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, particularly at an
 imbalancesettingofLOWSENSITIVITY.Formaximumcentrifugelife,settheimbalance 
 detectiontoHISENSITIVITYandalwaysrunbalancedloads.Refertopages8and9on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 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.MustbeLysol(1/4cup/gallon)or“Cidex”.
 NotallLysolwillbesufcient(mustbeaLysolAmphyldisinfectivecleanerorVirkon).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 shall not be
used. Before using any cleaning or decontamination methods except those recommended by the
manufacturer, users should check with the manufacturer that the proposed method will not
damage the equipment.
 Ifitisnecessarytoremovetherotorforadditionalcleaningitisrequiredthataqualied
technician remove the rotor assembly.
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!
If hazardous material is spilt on or inside the centrifuge, the centrifuge must be decontaminated.
6. Tube Holder Replacement: 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:
Horizon Lid Safety Switch: The Horizon lid is secured to the top of the cabinet by a locking 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 locked 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.
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 authorised dealer or Woodley Equipment Company.
Calibration and Earth Ground Testing:
It is recommended that the top speed, ground continuity and line leakage be tested every 12
months for continued safe operation. Contact Woodley Equipment Company for further information
or testing availability.
