 Safety Notice
Electrical Safety

Be sure to use the anchoring system to secure the centrifuge in place. The anchoring system is
designed to reduce the possibility of injury or damage that could result from instrument movement
in the event of a major rotor mishap.

Do not replace any centrifuge components with parts not specified for use on this instrument.

Electrical Safety

To reduce the risk of electrical shock, this instrument uses a three or five-wire electrical cord and
plug to connect this equipment to earth-ground. To preserve this safety feature:

• Make sure that the matching wall outlet receptacle is properly wired and earth-grounded.
Check that the line voltage agrees with the voltage listed on the name-rating plate affixed to
the centrifuge.
• Never use a three-to-two wire plug adapter.
• Never use a two-wire extension cord or a two-wire non-grounding type of multiple-outlet
receptacle strip.

Do not place containers holding liquid on or near the chamber door. If they spill, liquid may get into
the instrument and damage electrical or mechanical components.

Safety Against Risk of Fire

This instrument is not designed for use with materials capable of developing flammable or
explosive vapors. Do not centrifuge such materials (for example, chloroform or ethyl alcohol) in
this instrument nor handle or store them near the centrifuge.

Mechanical Safety

For safe operation of the equipment, observe the following:

• Use only the Beckman Coulter rotors and accessories designed for use in this instrument.
• Do not exceed the maximum rated speed of the rotor in use.
• NEVER attempt to slow or stop a rotor by hand.
• Do not lift or move the centrifuge while a rotor is spinning.
• NEVER attempt to override the door interlock system while the rotor is spinning.
• Do not lean on the centrifuge or place items on it while it is operating.

 Safety Notice
Chemical and Biological Safety

Chemical and Biological Safety

Normal operation may involve the use of solutions and test samples that are pathogenic, toxic, or
radioactive. Such materials should not be used in this instrument unless all necessary safety
precautions are taken.
• Handle body fluids with care because they can transmit disease. No known test offers complete
assurance that they are free of micro-organisms. Some of the most virulent — Hepatitis (B and
C) and HIV (I–V) viruses, atypical mycobacteria, and certain systemic fungi — further emphasize
the need for aerosol protection. Handle other infectious samples according to good laboratory
procedures and methods to prevent spread of disease. Because spills may generate aerosols,
observe proper safety precautions for aerosol containment. Do not run toxic, pathogenic, or
radioactive materials in this centrifuge without taking appropriate safety precautions. Biosafe
containment should be used when Risk Group II materials (as identified in the World Health
Organization Laboratory Biosafety Manual) are handled; materials of a higher group require
more than one level of protection.
• Dispose of all waste solutions according to appropriate environmental health and safety
guidelines.
It is your responsibility to decontaminate the instrument and accessories before requesting service
by Beckman Coulter Field Service.

Description

Introduction

This section describes the Avanti J-26S XP centrifuge components and their functions. It also describes
system safety features and centrifuge controls and displays. Refer to the applicable rotor manual for rotor
descriptions.

Centrifuge Function and Safety Features

Centrifuge Function
The Avanti J-26S XP is a refrigerated centrifuge that generates centrifugal forces required for a wide
variety of applications. Together with the Beckman Coulter rotors designed for use in this
centrifuge, applications include:
• Routine processing such as sample preparations, pelleting, extractions, purifications,
concentrations, phase separations, and spin column and spin filter centrifugations.
• Rapid sedimentation of protein precipitates, large particles, and cell debris.
• Preparation of subcellular organelles such as mitochondria, nuclei, chloroplasts, and crude
microsomes.
• Separation of blood cells and cellular components.
• Pelleting of prokaryotic and eukaryotic cells.
• Gradient separation, for example, Ficoll-Hypaque and Percoll.
• Nucleic acid precipitation.
• Virus isolation.
• Bacteriophase isolation.

The Avanti J-26S XP centrifuge is microprocessor-controlled, providing interactive operation.* The

centrifuge features a brushless switched-reluctance drive motor,† an automatic rotor identification
system, FRS (friction reduction system), vacuum control circuitry, and a temperature control
system with automatic temperature compensation unique for each compatible rotor.

The user interface has a digital display, which can be toggled to show either actual centrifuge values
or user-entered setup values, knobs for parameter entry, and touch keys. Diagnostic messages on
the control panel will light to alert the operator to conditions that may need attention.

 Description
Centrifuge Chassis

Safety Features
Avanti J-26S XP centrifuges have been designed and tested to operate safely indoors at altitudes up
to 2000 m (6562 ft).

Safety features include the following.

• An electromechanical door lock system prevents operator contact with spinning rotors and
prevents run initiation unless the door is shut and locked. The door locks when START is
pressed, or when the POWER switch is turned off.
• A steel casing surrounds the rotor chamber to provide operator protection in the unlikely event
of a rotor mishap.
• An automatic rotor identification system detects which rotor is installed and prevents the rotor
from running above its maximum rated speed.
• An imbalance detector monitors the system during operation, causing automatic shutdown if
rotor loads are severely out of balance.

Centrifuge Chassis

Housing and Door

The instrument control housing, door assembly, and cover panels are made from a highly-durable
unfinished plastic. The control panel is covered by a protective overlay made of coated
polycarbonate.

The door is opened by stepping on a foot pedal, which is located at the bottom right front of the
instrument. The door is hinged at the back left to open at a 60-degree angle to the centrifuge side
panels, providing clearance for loading and unloading of the centrifuge.

In the event of a power failure, the door can be manually unlocked for sample recovery (see
CHAPTER 3, Troubleshooting).

Rotor Chamber
The rotor chamber is made of stainless steel to resist corrosion. A rubber gasket around the
chamber opening ensures sealing. (Instrument gaskets have not been qualified as bioseals for
aerosol containment.)

Drive
The drive spindle is directly driven by a brushless, high-torque, switched-reluctance motor. The
instrument’s resilient suspension minimizes disturbance of the sample during acceleration and
deceleration, and reduces damage to the drive spindle if an imbalance occurs during centrifugation.

1-2 PN B10087AE
 Description
Name Rating Plate 1

Friction Reduction System (FRS)

The friction reduction system (FRS) uses a mechanical rotary vane vacuum pump to reduce
chamber pressure to approximately one-quarter atmosphere (190 mm Hg). The pump turns on after
the run is started, before rotor friction reaches a high level. When the required vacuum level is
reached, the pump turns off. Vacuum in the chamber is vented during rotor deceleration.

Temperature Sensing and Control

The temperature control system is cooled by circulation of a non-CFC-based refrigerant. The
temperature control system is activated when the centrifuge power is on and when the door is
closed.

A thermistor in the rotor chamber continuously monitors the chamber temperature. The system
calculates the chamber temperature required to maintain the set rotor temperature,  2°C.*
Although the chamber temperature fluctuates during operation, the rotor’s large mass keeps the
sample temperature substantially constant. At the end of a run, the system continues controlling
the temperature to prevent freezing or overheating (more than 4°C over set temperature) of
the sample.

Overtemp System
An overtemp (over temperature) system provides sample protection and safety for the user.

• During a run, if the system temperature rises 4°C above the set temperature, the TEMP
diagnostic will light. The run will continue, unless stopped by the user. If the temperature rises
8°C above the set temperature, the system will shut down (using maximum brake).
• The system will always shut down (using maximum brake) if the system temperature reaches
50°C. The centrifuge cannot be restarted until the chamber has cooled.

Name Rating Plate

The name rating plate is affixed to the rear of the centrifuge. Check that the line voltage agrees with
the voltage listed on this name rating plate before connecting the centrifuge. Always mention the
serial number and the model number shown when corresponding with Beckman Coulter regarding
your centrifuge.

* Refer to the applicable rotor manual for specific temperature information.

Digital Display
The display shows current status of the instrument whenever the power is turned on.

• The display shows both actual centrifuge values and user-set parameters. The SET/ACTUAL key
is used to toggle between the two views.
• During a run, actual values are displayed. If you turn a knob (other than the TIME knob) during
operation, the display will change to show the set values. If no parameters are entered or
changed for 5 seconds, the display will revert to showing actual values.
• During a timed run, the TIME display shows the remaining run time in hours and minutes. The
TIME display begins counting down when START is pressed and continues counting down to 0,
when deceleration begins. When the rotor decelerates to 0 RPM, End flashes in the TIME display.
• When HOLD is selected (no run time is specified), the TIME display shows the time elapsed since
START was pressed. After 3 hours (180 minutes) have elapsed, the timer will reset to 0 and
continue counting elapsed time until STOP is pressed.

Knobs and Touch Keys

The rotor name, speed, time, and temperature settings are entered by turning the appropriate knob
until the required value is displayed.

Touch keys allow the user to start and stop the centrifuge, and to select speed mode (RPM or RCF),
time mode (specific run length or hold for continuous operation), and acceleration and deceleration
rates, and to toggle the display between set and actual values.

ROTOR Knob Used to select the rotor in use. As the knob is turned, the name of each
Beckman Coulter rotor that can be run in the centrifuge appears in succession in
ROTOR the ROTOR ID display, and the LED by each rotor type abbreviation

JA
JLA
(JCF: continuous flow rotors; JSP: special type rotors; JS: swinging bucket rotors;
JSP JV JA: fixed angle rotors; JLA: lightweight fixed angle rotors; JV: vertical tube rotors;
JCF JE JE: elutriator rotors) lights when appropriate.

SPEED Selection The RPM/RCF key is pressed to select the speed mode (RPM or RCF). After the
mode is selected, the SPEED knob functions as follows.
• In RPM mode, each SPEED knob increment is 100 RPM at speeds up to
10,000 RPM. Above 10,000 RPM, each knob increment is 500 RPM.
• In RCF mode, at settings less than or equal to 3000  g, each SPEED knob
increment is equivalent to incrementing/decrementing the speed by 100  g.
At settings greater than 3000  g, each SPEED knob increment is equivalent to
incrementing/decrementing the speed by 250  g.
• Speed increments for elutriator rotors are either 10 RPM or 10  g.

PN B10087AE 1-5
 Description
Controls and Indicators

TIME Selection Two time modes are available. The HR:MIN mode is used for runs of specified
lengths. The HOLD mode is used for continuous runs of unspecified lengths. The
HOLD key is used to toggle between the two modes.
In HR:MIN mode:
• The TIME knob is used to set run time, which can be set up to 3 hours and
0 minutes (180 minutes).
• Each TIME knob increment is 1 minute. A full turn of the knob equals
60 minutes.
• The time setting can be changed during a run.
• During a run, the time remaining in the run is displayed. When 0 is reached, the
run ends and the rotor decelerates to a stop.
In HOLD mode:
• When HOLD mode is selected, the time display shows the word HOLD.
• During a run, the time elapsed is displayed. When the display reaches 3 hours
and 0 minutes, the system automatically resets the display to 0 and begins
counting the elapsed time again. The run will continue until STOP is pressed.
• If you switch from HOLD mode to HR:MIN mode during a run, the system
remembers the previous time setting. Turning the TIME knob increments or
decrements the set time from that point.

TEMPERATURE Used to select the rotor temperature, from –10 to +40°C.

Knob • The minimum and maximum allowable set temperatures depend on the set
speed and the rotor in use. If a temperature is entered that cannot be achieved
by the installed rotor at the set speed, the TEMP°C field will flash.
• The maximum achievable rotor temperature depends on the frictional heat
generated inside the chamber during operation. At low run speeds or low
ambient temperature, the centrifuge may not be able to achieve some higher
temperatures.

ACCELERATION Used to select either maximum or slow acceleration. An indicator light above the
Key ACCEL key displays the selection. Acceleration rates are described in Table 2.1).

 CHAPTER 2
Operation

Introduction

This section contains detailed centrifuge operating procedures. A summary is provided on page 2-1.
If you are an experienced user of this centrifuge, you can turn to the summary for a quick review of
operating steps.

WARNING
Normal operation may involve the use of solutions and test samples that are
pathogenic, toxic, or radioactive. Handle body fluids with care because they can
transmit disease. No known test offers complete assurance that they are free of
micro-organisms. Some of the most virulent — Hepatitis (B and C) and HIV (I–V)
viruses, atypical mycobacteria, and certain systemic fungi — further emphasize
the need for aerosol protection. Handle other infectious samples according to
good laboratory procedures and methods to prevent spread of disease. Because
spills may generate aerosols, observe proper precautions for aerosol
containment.
Do not run toxic, pathogenic, or radioactive materials in this centrifuge without
taking appropriate safety precautions. Biosafe containment should be used when
Risk Group II materials (as identified in the World Health Organization Laboratory
Biosafety Manual) are handled; materials of a higher group require more than one
level of protection.

WARNING
Do not use the centrifuge in the vicinity of flammable liquids or vapors, and do not
run such materials in the centrifuge. Do not lean on the centrifuge or place items
on it while it is operating.

The door opens.

3 Install the rotor according to the instructions in the rotor manual.

a. Always run the rotor with a balanced load.
b. (If you are using a swinging bucket rotor, fill all positions on the yoke with buckets.)
c. (If you are using a J-Lite rotor with cannisters, place a cannister in each rotor body cavity.)

CAUTION
Do not drop the rotor onto the drive hub. The drive shaft can be bent if the rotor
is forced sideways or dropped onto the hub. Install the rotor by centering it over
the hub and carefully lowering it straight down.

4 Securely attach the rotor lid knob, or tie-down knob in rotors without lids, to the drive shaft by
turning it to the right (clockwise).

NOTE If the knob turns loosely and you do not feel threads engaging, the rotor drive hole pins may not
be properly seated on the centrifuge hub. Lift the rotor up above the hub, rotate it slightly, and lower
it onto the hub again. Tighten the knob.

5 Close the centrifuge door firmly.

CAUTION
If you leave the rotor in the centrifuge between runs, make sure the rotor is seated
on the drive hub and the tie-down knob is tight before each run. (Remove the rotor
from the centrifuge if you anticipate a long period between runs.)

NOTE At the end of the run, after disassembling the liquid and power lines, be sure to replace the
black rubber stoppers in the ports at the left side of the centrifuge door. Failure to seal these
openings will prevent proper operation of the FRS system, which will cause a diagnostic shut
down during the next run.

Starting a Run

1 Check that all parameters are correct and the door is firmly closed.

2 Press START.
• The display will start showing actual centrifuge values within 5 seconds.
• The LED on the START key flashes during acceleration.
• When set speed is reached, the light stays on continuously until the centrifuge begins
decelerating.
• As the run begins, the system identifies the installed rotor.
• The system verifies that the user-selected rotor and the installed rotor are the same.
• If the system detects that the installed rotor is not the rotor that the user selected with
the ROTOR knob, and the speed selected by the user is greater than the installed rotor’s
maximum permitted speed, the system will reduce the run speed to the maximum allowed
for the installed rotor.

Changing Parameters During a Run

While a run is in progress, the speed, time, temperature, and acceleration or deceleration
setting can be changed without stopping the run. The rotor name parameter cannot be changed
during a run.

Changing Time Settings

1 To increase or decrease the remaining run time, turn the knob to the new run time.
• The system will add the new remaining time to (or subtract from) the time already elapsed,
and the display will show the new remaining run time.
• If you turn the TIME knob to a value less than the length of time the centrifuge has already
been running, the run will end and the rotor will begin to decelerate immediately.
— For example, if the centrifuge has been running for 20 minutes and you turn the knob
until 10 shows in the display, the run will end.

2 To set a completely new run time while a timed run is in progress, turn the TIME knob to the
new time setting and press START.
The system will ignore any elapsed time.

3 To change from HR:MIN mode to HOLD mode, press the TIME/HOLD key.
The display will show the total accumulated run time and will begin counting the time elapsed
from that point.

4 To change from HOLD mode to HR:MIN mode, press the TIME/HOLD key and turn the TIME knob

a. Press START.
The system will ignore any elapsed time and will begin displaying the time remaining in
the run.

Stopping a Run

A timed run ends automatically when the TIME display counts down to zero. “End” will flash in the
TIME display. To end a HOLD run or a run in progress for any reason, press STOP.

NOTE If a diagnostic condition causes the run to stop, with or without use of the brake, the appropriate
diagnostic message will light and the light on the STOP key will flash until the rotor comes to a
complete stop.

1 Press STOP to initiate deceleration.

Unloading the Centrifuge 2

2 After the rotor stops spinning, step on the foot pedal located on the front of the centrifuge, to
open the door.

NOTE During runs at very cold temperatures, nominally –10°C or below, ice may form around the door
opening, causing the door to stick shut. If this happens, press firmly on the door in several locations
around the door opening and depress the foot pedal again.
To minimize icing, remove moisture from inside the chamber, from the chamber gasket, and from
the inner door surface before each run by wiping these surfaces with a clean cloth. Also, keep the
door closed as much as possible.

Unloading the Centrifuge

At the end of a run, unload the rotor following the instructions in the applicable rotor manual.

CAUTION
If disassembly reveals evidence of leakage, you should assume that some fluid
escaped the rotor. Apply appropriate decontamination procedures to the
centrifuge and accessories as required.

If a problem occurs during operation, the appropriate diagnostic message will light and a beep will
sound to alert you to the condition. See Table 3.1 for a list of the diagnostic messages, the probable
causes, and the recommended actions.

Two kinds of diagnostic conditions can occur.

• Cautionary diagnostic messages alert you to a condition that may need attention when the run is
complete. Cautionary diagnostic messages provide information only; they do not shut down the
run in progress. Press CLEAR to stop the light from flashing. If the condition still exists, the
diagnostic message will begin flashing again, even though the run continues.
• Shutdown diagnostic messages occur when a problem exists that prevents the run from
continuing. The diagnostic message will flash and the red STOP key light will also flash,
indicating that the rotor is decelerating to a stop. You can press CLEAR to stop the diagnostic
message from flashing. However, if the diagnostic condition still exists (for example, if the rotor
is out of balance), another beep will sound and the message will start flashing again.

Table 3.1 contains information on causes and recommended actions for each diagnostic condition.

Accessing the Rotor in Case of Power Failure

WARNING
Any maintenance procedure requiring removal of a panel exposes the operator to
the possibility of electrical shock and/or mechanical injury. Therefore, turn the
power off (O) and disconnect the instrument from the main power source by
removing the Mains (power) plug from the outlet receptacle, and refer such
maintenance to qualified service personnel.

WARNING
Before performing this procedure, verify that the rotor is not spinning by listening
carefully for any noise coming from the chamber. Proceed only if the instrument
is quiet. Never attempt to override the door interlock system while the rotor is
spinning.

If the facility power fails only momentarily, the centrifuge will resume operation when the power
is restored and the rotor will return to the set speed. In the event of an extended power failure, it
may be necessary to override the door-locking mechanism manually to remove the rotor and
retrieve your sample.

To access the door-locking mechanism, you must remove the centrifuge front panel. Two latches
secure the front panel in place; these latches are accessible through two holes at the upper right
and left of the panel (see Figure 3.1).

Accessing the Rotor in Case of Power Failure

1 Turn the power switch to off (O) and unplug the power cord from the main source by removing
the Mains (power) plug from the outlet receptacle.
• The Mains (power) plug is the disconnect device and must remain easily accessible.
— Position the centrifuge so that it is easy to remove the Mains (power) plug from the
outlet receptacle.

2 Insert a 4-mm or 5/32-in. Allen wrench straight through one of the holes (either one) and turn
the wrench to the left (counterclockwise) until the latch disengages.

3 Repeat step 2, inserting the Allen wrench through the other hole.
• After the second latch disengages, the front panel will fall forward about an inch from
the top.
• The bottom of the front panel is held in place by three grooved brackets, attached to the
front panel, that seat over a metal retaining strip on the centrifuge bottom panel.

4 Lift the front panel up and off the centrifuge; set it aside.
• You will see an inner front panel that extends about halfway down from the centrifuge top
(see Figure 3.2).
• Below this inner panel is a black manual door release interlock lever (see Figure 3.2).

5 Pull the interlock lever out and to the left (at about a 45-degree angle), and while holding it out,
step on the foot pedal.
Depending on the level of vacuum in the chamber at the time of the power failure, the door may
or may not open.
a. If it opens, go to step 6.
b. If it does not open, you will need to manually vent the vacuum. Go to step 7.

6 After the door opens, first release the foot pedal and then release the interlock lever.
Sample can be removed.
a. Go to step 10.

7 To vent the chamber vacuum, grasp the red rubber hose and pull it up until it comes off of the
pump fitting (see Figure 3.3).
a. Use a back-and-forth motion as you pull; this takes quite a bit of force.
The vacuum will be completely vented several seconds after the hose is detached.

NOTE Several tubing lines are tied to the red hose. As you grasp the hose, place your hand over
these lines. Make sure that they stay connected as you pull.

CAUTION
Do not twist the hose to the left (counterclockwise) as you pull the hose, or you
will unscrew the hose fitting.

8 Replace the hose by pushing it down over the fitting as far as it can go.

JCF-Z Rotor Identification

The rotor identification system can, under two specific conditions, misidentify the JCF-Z
continuous flow/zonal rotor. Misidentification has occurred if a rotor name other than JCF-Z
appears in the ROTOR display during the run, when rotor identification is complete. If the rotor is
misidentified, stop the run and follow one of the steps below.

NOTE Misidentification can be prevented by returning your JCF-Z rotor to the Beckman Coulter factory to
have magnets added to the rotor body. The magnets ensure correct identification. Call your local
Beckman Coulter Field Service representative* for more information.

JCF-Z rotors manufactured after March, 1997, have factory-installed magnets.

* In the United States, call 1-800-742-2345. Outside the U.S., contact your local Beckman Coulter office or visit us at

 Troubleshooting
JCF-Z Rotor Identification

1 On the first few uses of a new JCF-Z rotor, or in an older JCF-Z rotor with newly replaced bearings, run
the rotor from 0 to 5000 RPM and back to 0 RPM three times.
This procedure will distribute lubricant around the bearings in the rotating seal assembly,
reducing drag.

2 In older JCF-Z rotors with bearings that have not been replaced recently, follow the same procedure
as for a new JCF-Z rotor (perform three runs from 0 to 5000 RPM and back to 0 RPM) to ensure
that the bearings are properly lubricated.
If misidentification recurs after the third run, when the bearings are lubricated, this indicates
that the bearings are worn and need to be replaced.
a. Replace the bearings following the instructions in the JCF-Z manual (JCFZ-IM).

NOTE If the JCF-Z rotor is misidentified, the run speed will be limited to the maximum speed for the
identified rotor. (The maximum speed for the JCF-Z rotor is 20,000 RPM.)

 APPENDIX A
Preinstallation Requirements

Preinstallation Requirements

Do not attempt to install this instrument. Its purchase price includes installation by Beckman Coulter
personnel. Installation by anyone other than an authorized Beckman Coulter representative invalidates
any warranty covering the instrument.

Preinstallation requirements have been sent prior to shipment of the instrument. The following
information is provided in case the centrifuge must be relocated.

The centrifuge will be installed upon initial purchase by a Beckman Coulter Field Service
representative after preinstallation requirements for power and site preparation have been met.
The following equipment is required for preinstallation:
• Voltmeter
• For single phase centrifuges: two 30-ampere circuit breakers
• For three phase centrifuges: three 16-ampere circuit breakers
• Power receptacle (see Figure A.1 or Figure A.2)
• Drill for drilling holes in the floor for installation of anchoring kit bolts (see Securing the
Centrifuge to the Floor, later in this section). A 9.5 mm (3/8-inch) drill is required for concrete
floors. A 6.4 mm (1/4-inch) drill is required for wood floors.

Electrical Requirements
Power to the centrifuge should originate directly from a main power line transformer at a power
source known to be clear of erratic loads, spikes, and electromagnetic interference. Make sure that
there are properly rated thermal circuit breakers at the service panel to protect the centrifuge
circuit. If fuses must be used instead of the specified circuit breakers, the fuses may require a rating
of greater than 30 amperes (for single-phase centrifuges) or greater than 16 amperes (for three-
phase centrifuges).

Terminate the open end of the harmonized cord with a certified single- or three-phase connector
suitable for the power supplied in the country of intended use (see Table A.1). Install only one
centrifuge per circuit.

To ensure optimal safety, the centrifuge should be wired to a remote emergency switch (preferably
outside the room where the centrifuge is housed, or adjacent to the exit from that room). In case of
a malfunction, the centrifuge can be disconnected from the main power source by removing the
Mains (power) plug from the outlet receptacle.

WARNING
To reduce the risk of electrical shock, this equipment uses a three-wire or five-
wire electrical cord and plug to connect the centrifuge to earth-ground. To
preserve this safety feature, make sure that the matching wall outlet receptacle
is properly wired and earth-grounded.

Prior to instrument purchase, the power configuration should be determined and the appropriate
instrument ordered.

Single and Three-Phase Power Connections

Figure A.1 shows the power connection for single-phase centrifuges, including earth-ground and
two power leads with 30-ampere circuit breakers. Figure A.2 shows the power connection for three-

Additional Requirements for Three-Phase Power Connections

For three-phase power service to the centrifuge, use the “Y” connected configuration shown in
Figure A.3. Also note the following information:

• The steady state current draw of the centrifuge can be as high as 12 amperes per phase,
depending on the voltage.
• Inrush current to the centrifuge is 100 amperes for up to 2 seconds during the refrigeration
start period. Circuit breakers, whether thermal or magnetic actuating, must be a “motor start”
delay type.
• The centrifuge can tolerate a drop of 15 volts during the start period at low line voltage (see
Figure A.3 for the acceptable voltage ranges). The mains power for the centrifuge must be of
sufficient wire gauge to provide this condition. The wire gauge required at a particular site
must be determined by a facilities engineer at that site.

Space and Location Requirements

1 Locate the instrument on a clean, level floor.

• The Mains (power) plug is the disconnect device and must remain easily accessible.
— Position the centrifuge so that it is easy to remove the Mains (power) plug from the
outlet receptacle.

2 Select a location away from heat-producing laboratory equipment.

If ambient temperature exceeds 38°C (100°F), premature component failure may result.

3 In addition to space for the centrifuge, allow a 7.7-cm (3-in.) clearance on each side of the
centrifuge and a 16-cm (6.25-in.) clearance behind the centrifuge for air circulation.
The centrifuge must have adequate air ventilation to ensure compliance to local requirements
for vapors produced during centrifuge operation.

 Preinstallation Requirements
Using J2 Series Rotors in the Avanti J-26S XP

Securing the Centrifuge to the Floor

Avanti J series centrifuges are certified to meet the requirements of the European CE mark. To meet
these requirements, the centrifuge must be secured to the floor using the anchoring hardware
shipped with the instrument. This will prevent the centrifuge from moving in the unlikely event of
a rotor mishap.

Complete instructions for installing the anchoring kit are packaged with the hardware, which is
shipped with the centrifuge. The instructions (publication B10122) include a full-size template to be
used as a guide for drilling holes in the floor. Refer to this document for additional installation
instructions.

NOTE Beckman Coulter representatives are not equipped to drill holes in your floor. The holes must be drilled
before your scheduled installation.

Bio-Safety Level 3 Installation

For laboratories with epoxy aggregate (resinous) floors, such as BSL-3 labs, a non-invasive
installation kit (PN 393316) is available. The kit which consists of an adhesive-backed mounting
plate, is CSA certified for use on epoxy aggregate floors only.

Non-Invasive Centrifuge Restraint System for Vinyl Floors

For laboratories with vinyl tile floors or vinyl seamless floors, a non-invasive installation kit
(PN A84005) is available. The kit which consists of an adhesive-backed mounting plate, is CSA
certified for use on vinyl floors only.

Using J2 Series Rotors in the Avanti J-26S XP

CAUTION
Do not use the Beckman Coulter JA-10, JS-7.5, JA-14, or JS-13 rotors in the
Avanti J-26S XP centrifuge before reading this information.

Checking for Rotor Drive Pins

Rotors used in Avanti J series centrifuges must have drive pins in the rotor drive hole (see
Figure A.5). These drive pins engage with the centrifuge spindle hub to ensure that the rotor does
not slip during acceleration. Some Beckman Coulter rotors, including the JA-10, the JS-7.5, the
JA-14, and the JS-13, have been manufactured without drive pins because pins were not needed
when these rotors were used in J2 series centrifuges.

The rotor pins are positioned parallel to the Beckman name engraved at the center of the rotor body
(see Figure A.5). Knowing the pin orientation before you install the rotor will help to ensure that
you position the rotor properly on the hub, minimizing the chance of hub damage.

Check all J2 series rotors for drive pins before using them in an Avanti J series centrifuge and do not use
rotors without drive pins in the Avanti J. To check for drive pins, hold the rotor up or turn it on its side
and look into the drive hole. If you do not see two metal pins in the hole, do not use the rotor in the
Avanti J. Call your local Beckman Coulter office* for information on returning the rotor to the
factory for upgrading.

Using the JA-18 Rotor

In Avanti J series centrifuges, the JA-18 rotor must be run with the lid attached. See the JA-18 rotor
manual (publication J-TB-035) for complete rotor usage instructions.

Using the JCF-Z Continuous Flow/Zonal Rotor

Zonal Bracket Kits

A special bracket and mounting hardware are required when the JCF-Z Continuous Flow/Zonal
Rotor is used. These parts are contained in the Zonal Bracket Kit (part number 366431). The Zonal
Bracket Kit includes a bracket, mounting hardware, and assembly instructions. This kit is for use
with Cole-Parmer tubing size 16 (6.4 mm [1/4-in.] O.D.), the tubing size most commonly used with
the JCF-Z rotor.

Two additional kits are available, one which contains adapters for size 14 tubing (4.8 mm
[3/16-in.] O.D.) and one which contains adapters for size 15 tubing (9.6 mm [3/8-in.] O.D.). If you
wish to use either of these sizes of tubing, you will need to purchase one of these kits in addition to
the basic kit (366431).

See Replacement Parts and Supplies in CHAPTER 4 for a complete list of Zonal Bracket Kit part
numbers and kit contents.

Ensuring Correct JCF-Z Continuous Flow/Zonal Rotor Identification

The centrifuge’s rotor identification system can, under two specific conditions, misidentify the
JCF-Z continuous flow/zonal rotor. These conditions and corrective actions are listed below.

NOTE JCF-Z rotors manufactured after March, 1997, contain special magnets that ensure correct rotor
identification in Avanti J series centrifuges. We recommend that older JCF-Z rotors be returned to the
Beckman Coulter factory for addition of the magnets before use in the Avanti J-26S XP. Call
Beckman Coulter Field Service* for more information.

The following information pertains to JCF-Z rotors manufactured before March, 1997, and to JCF-Z
rotors that have not been modified at the factory.

• When the bearings in the JCF-Z rotating seal assembly get old or worn, the resulting “drag” on
the bearings changes the rotor’s dynamic properties, making them similar to those of several
Beckman Coulter fixed angle rotors. If rotor misidentification occurs when your JCF-Z rotor is
used, first perform three runs from 0 to 5000 RPM and back to 0 RPM. If rotor misidentification
recurs, replace the bearings. See the JCF-Z rotor instruction manual (publication JCFZ-IM) for
bearing replacement instructions. Be sure to follow instructions in the next paragraph below
for “wearing in” the bearings.
• On the first few uses of a new JCF-Z rotor, or when the bearings have been replaced in an older
JCF-Z rotor, lubrication has not yet been thoroughly distributed around the bearings in the
bearing housing. The excess lubrication produces drag on the bearings, which can change the
rotor’s dynamic properties enough to cause rotor misidentification. To “wear in” the bearings
and distribute the lubrication, perform three runs from 0 to 5000 RPM and back to 0 RPM.

NOTE If the JCF-Z rotor is misidentified, the run speed will be limited to the maximum speed for the identified
rotor. (The maximum speed for the JCF-Z rotor is 20,000 RPM.)

 APPENDIX B
Temperature Calibration Procedure

Introduction

The Avanti J-26S XP centrifuge specification for temperature control is 2°C of the set temperature.
That means that your sample will stay within 2°C of set temperature at all times, after rotor and
system equilibration, described below. (During transient conditions, such as acceleration and
deceleration, the rotor temperature may be outside this range.) The following procedure is
provided for those cases in which temperature control within 1°C is required.

In this procedure, you will measure the temperature of your sample after equilibrating the rotor
temperature for a minimum of 1 hour. Based on the test results, you can then adjust the centrifuge
temperature setting to bring your sample as close as possible to the required temperature.

1 For runs at other than ambient temperature, precool or prewarm the rotor and test samples to
the required temperature.
The length of precooling/prewarming time depends on how different the rotor starting
temperature is from the required run temperature.

2 Install the rotor with adapters, if applicable, and tubes or bottles filled with sample buffer or
water (if above 2°C).

3 Set the speed to 2000 rpm, the time to HOLD, and the temperature to the required run
temperature.
a. Start the run.

4 After 30 minutes, set the required run speed, and allow the system to run for at least 1 hour.

NOTE The system must run for at least 1 hour before the temperature of the buffer or water is
measured. The length of time required for equilibration depends on the rotor and centrifuge starting
temperatures and the ambient room temperature.

5 After at least 1 hour, measure the temperature of the buffer or water using a thermometer or
thermocouple.

6 If the measured and set temperatures are different, note how many degrees different they are
and adjust the set temperature up or down that number of degrees.
