2 Use according to the specifications
The present device is a wash centrifuge intended for in-vitro diagnostic applications, in accordance with
“Directive 98/79 EC”. The sample processing with the use of the device and the corresponding inserts is realised
by the filling with a washing liquid and subsequent shaking, centrifuging and decanting. The device itself is used
for sample processing and not for sample analysis.
The following device types are available for this device:
Rotolavit II, Type 1008-00 and 1008-03
These device types are used to wash respectively to clean erythrocytes for carrying out quick anti-human globulin
tests (direct and indirect Coombs tests) in crossmatch, antibody screening and differentiation.
Leukocytes can be washed in the same way to prepare samples for tuberculosis or tumour testing. The device
is intended exclusively for the applications mentioned and is only allowed to be used in closed clinical
laboratories by medically trained specialists.
Rotolavit II-S, Type 1008-00S
This device type is used to wash respectively to clean blood or other cell-containing samples to prepare the flow
cytometric analysis on a sample preparation system and flow cytometer. The process steps can be individually
configured by the user and stored in the device. The configured process steps are processed automatically by
the device. A wash-cycle may consist of several processes in which the samples are centrifuged, the
supernatant decanted, and then each sample tube is filled with a physiological saline solution and mixed.
The device should only be used by trained medical personnel in clinical laboratories and used only for the stated
purpose.

6 Unpacking the centrifuge
If packaging arrives damaged, it must be confirmed by the carrier and the centrifuge must be specially
inspected.
To avoid damage, do not unpack the appliance until you reach the installation site.
Check the delivery note to ensure that the delivery is complete. Check the appliance for damage.
Take care, you could injure your skin on the edge of the cardboard packaging carton.
Lift the centrifuge on both sides and not on the frontpanel. Take it out of the box with an adequate
amount of people to help you.
According to the laboratory instrument standards EN / IEC 61010-2-020 an emergency switch to
disconnect the power supply in the event of a failure must be installed in the building electrical system.
This switch has to be placed remote from the centrifuge, preferably outside of the room in which the
centrifuge is installed or near by the exit of this room.
Before the centrifuge is connected to the power or the lid is opened using the emergency opening,
place the centrifuge carefully on one side so that the three transport locking screws on the underside
of the centrifuge can be removed with the help of the enclosed hexagon L-key wrench. Carefully place
the centrifuge back on its feet, connect the power correctly, and operate the centrifuge and open the
lid, so that the transport foam of the supplied rotor, or the additional transport lock on delivery without
rotor, can be removed.
Position the centrifuge in a stable and level manner in a suitable place. During set-up, the required
safety margin of 300 mm around the centrifuge is to be kept according to EN / IEC 61010-2-020.1
When the centrifuge is running, according to EN / IEC 61010-2-020, no persons, dangerous
substances or objects may be within the safety margin of 300 mm around the centrifuge.
If you notice deviations from the delivery note, damage or irregularities, do not put the appliance
into operation, but inform the haulage company and your supplier.
If possible, keep the transportation material and the transportation safety device in a safe and dry place.
6.1 Storage after delivery
If the device must first be stored after delivery, then check the box from outside for damage and if it is so,
inform the haulage company and your supplier immediately. For the storage conditions, refer to tab. 1.0
technical specifications.
6.2 Installation after storage

7.3 First steps
Please check chapter 3 before starting the installation.
Install the power supply in its mounting bracket on the rear side (see Fig. 7.1, Pos. 2) and plug the connector to
the DC input (Fig. 7.1, Pos. 5). Plug the provided main power cable into the power supply and the other side to
the power source.
Check the country-specific regulations when making connections (e.g. in Germany with
residual current circuit breaker). Observe the connection and power ratings, see on the label
and the technical specification. Make sure to establish a safe PE conductor connection.
Lay the power cable so that
it is always accessible and within reach, so it can be disconnected in the event of
a failure
no one can trip over it
it does not have contact with a solution, e.g. water or saline, mechanical parts, e.g.
shakers or mixers, or hot parts, e.g. ovens or torches
Plug the connector from the fill hose to the inlet 1 on the rear side (Fig. 7.1, Pos. 7) and dip
the other side with the suction-tube into the container with the saline solution.
If the fill hose is too short for your installation and it is not possible to move the can with the
solution closer and you need an oversized fill hose (from your local distributor), then you must
validate the flush- and the refill pump programs for correct operation.
If your device has the optional inlet 2, plug the connector from the fill hose 2 to the inlet 2 on
the rear side, see on fig. 7.1, Pos. 8 afterwards dip the other side with the suction tube into
the container with the fluid 2 solution.
Ensure that it is not possible to interchange the ends from the tubes and the cans or
containers, otherwise all probes will be disturbed!
Plug the connector from the drainage hose to the outlet on the rear side, see on fig. 7.1 pos.
9, and put the other side into the waste.
Ensure that the drainage hose lies flat onto the base, if not and it is like figure 7.2.6, the
device will become damaged.
Clean and disinfect the device before first use.
