The machine must be installed in a dust and corrosion free room.
Leave a 30 cm / 12 in. space free on each side of and behind the
machine for safety reasons, proper ventilation and maximum cooling
performances.

Place the centrifuge on a bench top, which must be rigid, horizontal
and sufficiently strong to support the centrifuge’s weight and small
vibrations.
Place the centrifuge on a horizontal floor.
Check mains and frequency: they must correspond to the values shown
on the instrument identification label.
For your safety, check that mains wiring is effectively grounded.
Thermo declines all responsibility for any damages due to non-
grounding of the machine.

Remember that in order to respect the electrical safety standards related
to protection against indirect contact, the supply of power to the
instrument must be via a power socket fitted with a protection device
ensuring automatic cut-off in the case of an insulation fault. A supply
fitted with a circuit breaker of the correct rating complies with this
requirement.
Ensure that the centrifuge has been switched ON. Pull the handle on
the centrifuge right side towards the front of the unit : the lid is
automatically unlocked and opens.
In the case of a mains power outage, opening of the lid is prevented by
the lid lock safety device. It is recommended to wait for the mains
power to be switched back on so that this safety device enables the lid
to be unlocked (refer to 3.6 for manual lid opening).
Carefully clean the inside of the centrifugation chamber removing any
packing residues.
In fact, due to air turbulence, solid particles accidentally left in the
centrifugation chamber create excessive wear of the chamber itself and
of the outer rotating equipment surface.

To install the rotor:
• Check that the motor shaft and rotor are clean
