INSTALLATION PROCEDURE
2-2 MR23i Thermo Fisher Scientific
MAINS SUPPLY
The Jouan MR23i requires a single phase supply:
Maximum power requirement : 1300 VA (average: 1000 VA). The
centrifuge should be connected to a 3 wire earthed outlet.
Remember that in order to respect the electrical safety standards
related to protection of operators against indirect contact, the sup-
ply 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 cicuit breaker of the correct rating complies
with this requirement.
ENVIRONMENTAL
CONDITIONS
This instrument is designed to operate safely under the following
conditions:
• Indoor use.
• Temperature: 5° to 40°C.
• Maximum relative humidity of 80% for temperatures up to 22°C.
• Maximum altitude: 2000 m.
Maximum performance is assured across the following tempera-
ture range: 15°C to 25°C.
POSITIONING
Place the centrifuge on a bench-top, able to support its weight of
85 kg and vibrations, in a clean, noncorrosive environment. Posi-
tion the centrifuge. Leave a 30 cm space free on each side of the
machine and behind.
LID OPENING
When the centrifuge is switched on, wait until display returns to the
stand-by mode then pull forwards the latch lever located on the
right hand side of the unit: the lid is automatically unlocked and
opens.
MANUAL LID
UNLOCKING
In the case of a mains power cut, opening of the lid is prevented by
the lid locking safety device.
It is recommended to wait for the mains to be switched back on so
that this safety device enables the lid to be unlocked.
