3. If an odd number of samples is to be spun,

use a water-filled 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):

page 12

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:

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.

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.

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 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 carrier / holder. Insert a new tube

cushion (if necessary) and replace the tube carrier / holder in the rotor.

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.

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 qualified

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!

Tube carrier / holder replacement:

Tube carriers are stamped with an expiration date and

should be replaced according to this stamp.

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.
