1 INTRODUCTION
TheCentra-GP8seriesaregeneral purpose centrifuges designed foruse
in medical, industrial and scientific laboratories. The Centra-GP8 series is
available in the following models.
Benchtopmodels: 3121 - GP8 100/120/220/240Vac,50/60 Hz
3122 - GP8R 120 Vac, 60 Hz
3125 - GP8R 200/220/240Vac,50/60Hz
Kneewellmodels: 3123 - GP8(K) 100/120/220/240Vac,50/60 Hz
3124 - GP8R(K)120 Vac, 60 Hz
3126 - GP8R(K) 200/220/240 Vac, 50/60 Hz
FloorModels: 3127 - GP8(F) 100/120/220/240Vac,50/60 Hz
3128 - GP8R(F)120 Vac, 60 Hz
3129 - GP8R(F)220/240 Vac, 50/60 Hz
The Centra-GP8 series can develop a maximum relative centrifugal force
(RCF) of 4630 xg using the 822A rotor. The centrifuges will accommodate
a range of centrifuge tubes and devices including 750 mL bottles,
microplates, cytological slide carriers, and microsample tubes. Maximum
sample load is 3 Liters.
Designed for ease of use, the Centra-GP8 has an ergonomic touch pad
control panel and bright, easily read LED displays. The unit can be
operated in manual mode, hold, or one of 35 programmable operations.
Programs can also be modified at run time, offering unlimited run
variations. In addition, rotor number entry permits automatic calculation of
RCF. Other features include a coast mode and separate acceleration and
deceleration controls for maintaining delicate samples such as those with
densitygradients.
All refrigerated models allow you to select chamber temperatures from
-5°C to 40°C and will maintain 2°C at full speed with the 218 rotor. All
refrigerated models also offer a Rapid Condition function for pre-cooling
or pre-heating the rotor and sample chamber. Repeat runs with precisely
the same temperature, speed and time setting can be achieved with the
touch of a button.
The internal microprocessor that allows this simplified operation also
ensuresrepeatableresults,preventinginadvertent loss of sample,and
evenalertsoperatorswhen periodic maintenance isdue.
The Centra-GP8 series rugged steel cabinet and rigid construction
providequietoperation andlong-termreliabilitycoupled withimpressive
safety features. A fail-safe cover interlock prevents the rotor from running
unless the cover is closed. It also prevents the cover from being opened
until the rotor has slowed to less than 90 RPM, even if the power fails. If a
load-imbalance occurs, a sensor shuts the unit down and triggers a
warningmessage.

2 INSTALLATION
IEC ships the centrifuge in a carton that protects it from shipping hazards.
Follow the unpacking instructions on the carton. Be sure to complete the
postage-paid warranty card and return it to IEC (U.S. and Canada) or to
thelocaldistributor(Export).
2.2 Site Preparation
For benchtop units, place the unit on a smooth, clean, dry surface to
ensure that the suction feet grip firmly. The surface must be rigid, stable
andleveltoensurequiet, vibration-free operation.
Clear the area beneath the unit of debris and loose material such as
paper. Allow 8 cm (3 inches) of clearance near the ventilation grill of
refrigeratedunits.
For Kneewell and Floor Model units, make sure that the floor is clean,
stable and level, and that the unit has at least 8 cm (3 inches) of
clearance for the GP8 and 16 cm (6 inches) of clearance for the GP8R at
the rear for ventilation.
Warning: Lock the front wheels before starting a run to avoid
dangerous movement. To gain access to the caster locks, pull the
centrifuge forward about 15 cm (6 inches) and then swing backwards to
swivel the casters to the front.
Section 6 of this manual provides specific dimensions and specifications
for each of the Centra-GP8 units.
Clearance Envelope InternationalElectrotechnicalCommission standard1010part 2-20limits
the permitted movement of a laboratory centrifuge to 300mm in the event
of a disruption. The user should therefore mark the clearance envelope
boundaryaround thecentrifuge,orlaboratorymanagementprocedures
should require that no person or any hazardous materials are within such
a boundary while the centrifuge is operating.
2.3 Power Configuration
Do not plug in the centrifuge until you have configured the power
correctly. For best results, the centrifuges should be used on a
dedicated line. Variations in line voltage or frequency will affect the unit’s
speed and other characteristics. Less than nominal line voltage may
preventthecentrifugefromreaching published specifications ofspeed
and/or temperature. Also, power line voltage at some locations may sag
when the refrigeration system turns on.
Caution: Configuring the centrifuge incorrectly may damage the
equipment and will void your warranty.
