2.General warnings
Only authorized personnel can use this centrifuge. The user must go through the instructions and
understand every aspect before using this machine. In case of malfunction, contact the supplier.
This centrifuge must not be placed inside another unit or electrically or mechanically connected to
another unit. Only the rotors and accessories supplied with this centrifuge and by this manufacturer
should be used with this machine. Check that they are not damaged before each use. The rotors and
accessories of this centrifuge must not be used on centrifuges of other brands and viceversa.
Do not place flammable samples, chemicals with exothermic properties, explosive or highly reactive
substances for centrifugation inside this centrifuge.
No person other than those authorized by the manufacturer is authorized to make modifications to
the centrifuge after shipment from the factory.
In case of any damage to the unit or in the presence of abnormal noises or anomalies, stop the use of
this centrifuge and immediately report the fault to the supplier.
In case of liquid spills, disconnect the device from the power supply and thoroughly clean the device
and accessories, following the cleaning and disinfection instructions given in the instruction’s manual.
Never attempt to override the safety systems and / or work with the centrifuge lid open.
Give particular attention when using dual sand witch tubes with internal filters, when the filter
porosity is not similar in the tubes, it can lead to unbalance at high speeds thereby causing irreparable
damage to the machine.
When opening and closing the lid, do not grasp the part between the lid and the centrifuge, do not
insert your fingers into the centrifuge closure and do not grasp the lid locking mechanism, this could
cause physical damage.
Make sure that the centrifuge lid opens completely and remains in the open final position. Regularly
check that the gas spring works perfectly. In case of malfunction, contact the supplier's technical
service.
In case of emergency lid release, the rotor could continue rotating for a few more minutes.
Check through the peephole in the lid that the rotor has stopped before intervening on the
"emergency opening".
When changing the rotor, the power supply must be disconnected. This operation must be carried out
by qualified personnel.
The tubes must always be weighed complete with contents and caps.
Place the tubes symmetrically before starting centrifugation. Use only metal buckets suitable for the
type of rotor used and tubes suitable for adapters used. Use only tubes that have been approved by
the manufacturer with the desired g (rcf) values. Do not use fragile or deforme tubes.
The centrifuge is designed for centrifuging substances with a maximum density of 1.2 g / ml, at
maximum speed and at maximum volume filling / load. Do not exceed the maximum rotor load.
Never use chemicals or cleaners which could be naturally corrosive. This could cause damage to the
centrifuge. Use a dry cloth to clean the inside of the chamber.
The interior of the chamber must be cleaned and checked regularly for contamination.
In case of continuous use of the refrigerated models, turn off the centrifuge regularly to let the ice
melts, remove any deposits and condensing formation using a soft and absorbent cloth. This is useful
for decreasing icing and compressor overheating during cooling.

•Biological safety
During operation, the centrifuge can generate particles suspended in the air. Since these NEYA 8/10/16 models are
not refrigerated centrifuges therefore they do not have a completely sealed chamber. This type of ventilated
centrifuge helps to reduce the excess heat created by the friction of the rotor with air in the internal chamber,
while the Neya 10R / 16R refrigerated models have a totally sealed chamber. To minimize the risks of aerosols
coming into direct contact with the person, always use tubes with biosafe lids. Glass tubes, if used, should not be
filled to the top to avoid spilling of liquid. Also, since the lid on the top has a gasket, you must make sure that this
gasket is not damaged. As it prevents direct exposure of the user with the sample. It is also advisable to open the
centrifuge lid 3 minutes after the centrifuge has stopped. This will give the particles time to disperse into air.
Bioseals (biological seal) is a part of biological safety systems, which are unable to guarantee the safety of people
and the environment when handling pathogenic microorganisms or infectious liquids. When working with
pathogenic organisms or infectious liquids of a high-risk group, more than one aerosol-tight seal must be provided.
If liquids are spilled into the chamber or into the rotor housing, the centrifuge must be thoroughly and entirely
cleaned by specialized personnel. In case of contact with infectious liquids and pathogenic germs, comply with
national regulations, the biological safety level of your laboratory, the safety data sheets and the manufacturers'
instructions for use. Wear personal protective equipment’s.
•Safety and/or protection devices
•Safety lid interlock to prevent lid opening during centrifugation.
•Detection of unbalances and stop of centrifugation with display error.
•Emergency unlocking of the lid.
•Gas hinge to prevent the door from falling.
See descriptions in the rest of the manual.
•Intended use

Move the opening lever of the lid on the left side (frontal view), the lid opens and rises by the action of the gas
spring. If necessary, conclude manually the opening of the lid.
ATTENTION:
The centrifuge has a safety opening system usable in case of power supply absence.
For safety reasons it is strongly recommended to open the machine in this condition only if necessary.

15
UM Neya EN rev.0 28.02.2022
In that case, you must respect the instructions written on safety sticker that cover the emergency opening hole
(see Figure 9).
In case of emergency opening, wait at least 15
minutes before open the lid.
Warranty and safety rules are not guaranteed
if this sticker is broken.
Figure 9 –Safety sticker
After have waiting at least 15 minutes from the moment of power supply absence, visually check that rotor is
stopped through the observation window on the lid of centrifuge.
Using the small Allen key supplied or alternatively a small screwdriver, pierce the safety sticker and leveraging
down. At the same time pull the opening handle.
Warning:
As specified on safety sticker, the warranty and safety rules are not guaranteed if this sticker is broken.
The above sticker is not removable and not modifiable, so in case that operator needs to open the lid in case of
power supply absence, please contact the technical assistance service for specifying the incident and restore the
label of safety.
•Installation of the rotor

1
Turn the motor shaft until the flat part is aligned to the arrow ▼present on
the seal (see side picture).
2
Turn the rotor in order that the arrow ▲printed on it is aligned with the
arrow ▼present on the seal (see side picture).
3
Insert the rotor on motor shaft makingthat the flat part of the shaft matches
with the one of the rotor.

16
UM Neya EN rev.0 28.02.2022
4
Hold the motor with one hand and with the other one screw the lock nut
clockwise.
Using the wrench supplied, tighten the lock nut until it is well locked (see
side picture).
5
Check that rotor is properly fixed trying to move it with both hands.
•Load and balancing of the rotor
•Automatic rotor detection
The centrifuge is equipped of an automatic rotor detection system.
This feature is very important for the safety of operator and of the machine, which prevents that:
•the centrifuge works beyond the speed limit of the rotor;
•the centrifuge works without rotor installed.
ATTENTION:
Even if it’s not necessary set the rotor during programming and the automatic recognition avoids exceeding the
maximum permitted speed, it is still essential that the operator knows well the limits of the rotor and accessories
with which equips the machine. These limits are always specified on the accessories.
•Load of the rotor
Warning:
The centrifuge has been designed and built to centrifuge liquids or liquid samples containing small solid particles.
It is strictly forbidden centrifuge solids of any kind. Any damage caused by the use during centrifugation of this
type of materials is not covered by warranty.
Moreover, also the centrifugation of explosive materials or having dangerous chemical reactions is strictly
prohibited. Any damage caused by the use during centrifugation of this type of materials is not covered by
warranty. It is strictly forbidden to centrifuge samples loaded directly into the metal bucket or carrier.
Samples must always be centrifuged within a container (tube or bottle with flat bottom).
Any damage caused by failure to comply with these conditions of use is not covered by warranty.
The samples to be centrifuged should never exceed the density of 1.2 g/ml. The tubes must be realized in very
good quality material. They tend to heat up during centrifugation, so before use them check their temperature
limits. Moreover, check their speed limit that often is lower than the one of rotor: for example, for glass tubes.
In case of the tubes have caps, seal properly them before centrifugation, to avoid eventual losses of sample.
•Balancing of the rotor
Warning:
Before to start a centrifugation cycle is essential to properly balance the rotor loads.
The load balancing should always be performed in accordance with the rule of the loads symmetry, which must
always be considered in terms of weight and not by volume.

17
UM Neya EN rev.0 28.02.2022
Rotors are generally used completely full: all the places are filled with tubes. If the samples are not sufficient to fill
all the places, it is recommended to use all of them filling the empty ones by tubes with water.
This permits the correct symmetric balancing necessary for acceleration and deceleration phases more linear.
Warning:
In any case, both with complete filling or with partially filling, it is absolutely necessary to distribute the loads
symmetrically around the axis of the rotor.
If the loads were not well balanced and the centrifuge went into unbalance, the centrifuge would stop immediately
and go into "unbalance error" (see Figure 7). Here are some examples of correct and incorrect balances:
Warning:
In case of configuration with aluminium carriers, the use of the same type and model is strongly recommended for
all four rotor housings. The use of alternating and different carriers would damage the rotor and the centrifuge.

UM Neya EN rev.0 28.02.2022
•Message “Motor Imbalance”
The centrifuge is equipped by an automatic system for imbalance detection.
If it is used with a load not balanced correctly, the machine will automatically stop and signals a fault to the operator
with intermittent beep and message "Motor Imbalance" on flashing red screen. If this occurs, you should wait until
the centrifuge stops and open the lid. Opening the lid the error message will disappear. Once you open the lid to
check the correct load balancing as described at § 8.
•Message “ERROR check imbalance switch”
Note: The system for the imbalance detection is magnetic, so it can sometimes happen that it remains
"closed" and then the centrifuge gives the following error message "ERROR Check imbalance switch".
To eliminate the error is sufficient to slightly push for a couple of seconds the motor shaft towards the rear part
of the centrifuge by directly pressing the rotor by the hand. If it’s necessary, repeat the operation.
When you switch on the centrifuge for the first time, it may give the above error message. The situation is normal
and is due to the transport of the machine with tabs that hold the motor shaft. Follow the steps above to clear the
error.
•Setting of programs (if present)
The follow instructions are valid for centrifuges NEYA 10/10R and NEYA 16/16R. To set centrifugation parameters
for NEYA 8 please refer to paragraph 8. With closed lid and centrifuge in standby mode (see Figure 4), press shortly
SETUP/ESC key, display goes into SETUP menu and word “PROGRAM” starts to blink (see Figure 10).
