Centra-GP8/GP8R Operation Manual

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
the local distributor (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
and level to ensure quiet, 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
refrigerated units.
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 International Electrotechnical Commission standard 1010 part 2-20 limits
the permitted movement of a laboratory centrifuge to 300mm in the event
of a disruption. The user should therefore mark the clearance envelope
boundary around the centrifuge, or laboratory management procedures
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
prevent the centrifuge from reaching published specifications of speed
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.
