1.2.2 Safety Precautions
•Supply proper voltage power according to device’s power requirement.
•Let all repairing works done by authorized or qualified personnel.
•Use rotors or accessories which are approved by Gyrozen.
•Not try to open the lid and or move the device while the rotor is running.
•Operate the centrifuge with a rotor properly attached and secured to the shaft.
•Not use flammable, hazardous, explosive, or corrosive materials.
NOTE: When it is required to use toxic, radioactive materials or pathogenic micro-
organisms, which belong to the Risk Group II of WHO: “Laboratory Bio-safety Manual,”
should follow the regulation guidelines from WHO.
•Keep away hazardous materials farther than 30 cm (12 in) from the device during
centrifugation, as recommended in IEC standards 61010-2-020.
•Keep the rpm or rcf under its maximum speed in the case that the density of sample
materials is greater than 1.2 g/ml to avoid rotor failure.
•Load samples symmetrically in the rotor diagonally to make balance between the tubes.
•Balance the load on the rotor totally to prevent the damage to the device even by using
several water-filled tubes.
•Place device on a flat, level, rigid and stable surface.
•Disconnect power supply prior to maintenance and service work to avoid electrical shock.
•Use proper disinfection procedures when centrifuging bio hazardous compounds.
When a blackout takes place while the device is running, the door does not open. And the
rotor speed begins to decrease at natural level. Even if the power turns on before the rotor
stops completely, the rotor does not return to the original speed, but decreases more rapidly
with buzzer sound.
The door is closed/opened automatically by a door lock unit operated by a solenoid, and it
will not be opened while the rotor is running at all. Even if the door is opened accidentally,
a door limit switch senses it instantly to make the rotor speed decrease.

2) Open the box and lift out the device carefully together with the safety padding.
3) Remove the safety padding and vinyl wrap.
4) Place the device on the flat surface.
2.2 Location
1) Install the device at the solid and flat floor or table. If you place the centrifuge at
the slope, the axis of rotation is possibly changed because of the rotor weight.
2) Install the device keeping a distance of 30cm at least from the wall.
The distance is needed for the air circulation around the device.
3) Install the device at the place with appropriate temperature and humidity.
These conditions have to be maintained constantly as soon as possible.
4) Install the device at the place without any kinds of corrosive gases.
2.3 Supply the power
1) mini model uses 110V or 220V.
Check proper voltage of the device and connect to adequate power outlet.
2) If the power input is more than +/- 10% of the recommended voltage or
fluctuating frequently, it may affect some functions of the device.
In that case it is recommended to use AVR (Automatic Voltage Regulator).
3) If you want to use the device under the other voltage range, please contact us for
safe usage.
2.4 Power On and opening front door
1) Turn on the device by the switch on the back side of the device.

with neutral detergents and clean contaminated parts. Keep dry completely after
cleaning.
② Do not use any volatile chemicals such as alcohol, benzene, etc.
③ If any rust appears, clean with neutral detergents and dry it.
2) Inner part of device
① Keep dry inside the chamber after every use of the device.
② Clean the shaft always for avoiding an imbalance error during the rotation.
③ If any part is contaminated, clean with neutral detergents.
3) Rotor
① Clean the rotor if rotor is contaminated by any samples.
② Keep dry it after usage.
4) Moving or shipping of device
① If you need to move the device, make sure to protect the shaft from any physical
impact.
② Remove the rotor and fill inside the chamber with proper materials to keep the
shaft on place.

7.2 Device test for centrifuge
7.2.1 Validation of actual RPM
1) Prepare a RPM speed tachometer (hand
tachometer) and fluorescent light tape.
2) Attach some fluorescent light tape on a grip
of a rotor lid.
3) Set the specific rpm and start the operation.
4) Measure an actual rpm using the tachometer
through center window of main body lid.
5) Compare actual measurement rpm and setting
rpm.
7.2.2 Validation of Motor performance
Check the resistance value at motor output terminals (Unit: Ω)
Measuring method
1) Use ‘Multi meter tester’ tool
2) Place the tool at the resistance location
3) Check the resistance value at u-v, u-w, v-w with tester.
4) If the value is 0 or ∞ ohm, it means some trouble so it needs repairing.
5) The normal status is that 3 resistance values(u-v, v-w, w-u) are all same within a
range of ±5%.
