1. Operating instructions
1.1 About this manual
This service manual should be used by specialized engineers authorized by Gyrozen Co.,
Ltd.
Any repairing work operated by non-authorized personnel cannot be protected and
guaranteed.
This service manual aims to find possible errors quickly and fix them properly.
Refer to the user’s manual for detailed operation of Centrifuge.
Do not copy or reprint without approval

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 door 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.
(http://www.who.int/csr/resources/publications/biosafety/Labbiosafety.pdf)
•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 operated automatically by a door lock unit including a motor, and it does not open
while the rotor is running. If the door is opened accidentally, E2 error code appear and the rotor
speed decrease.
If the rotor loses balance while running by any reason, it invokes vibration on the device itself.
In this case the Imbalance sensor senses it and makes the rotor begin to decrease with preset
level issuing Imbalance Error warning. This safety function protects the device from damage during
operation.

2. Installation
The 1580R is a rotor auto-recognized model. But an instrument is delivered without a rotor, so
when you turn on the machine, the system tries to recognize a rotor automatically, and ‘Error 9’ is
appeared because of absence of a rotor. Mount the rotor and turn off the machine, and turn on
again. Then the instrument recognizes the rotor properly.
2.1 Unpacking
1) Lift the carton upward and remove the safety padding.
2) Lift the instrument on the four sides of the machine with appropriate number of helpers.
3) Place it to the flat space.
4) Remove motor fixing bolts 3ea of screw bolts are placed at the bottom of the unit for
prevention of damage to the imbalance sensor caused by any moving of the motor
during delivery. These bolts should be removed before the installation of the unit.
① Check if a long bolt came out from bottom of the unit.
As it is longer than the leg pieces, the unit cannot stand horizontally.
② Check two more bolts around the fan net.
③ Unscrew 3ea of bolts with a provided wrench.

2.2 Location
1) Install the device on 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 about 30cm departed from the wall for effective air circulation.
3) Install the device at the place with appropriate temperature and humidity. It also has to
be maintained with the proper temperature & humidity.
4) Install the device at the place without any kinds of corrosive gases.
2.3 Supply the Power
1) The 1580R model uses 110V or 220V. Check proper voltage of your instrument and
connect to adequate power outlet.
2) If the power input is more than +/- 10% of the recommended voltage or fluctuates
frequently, it may affect some functions of the instrument. It is advised to use AVR
(Automatic Voltage Regulator).
3) If you want to use the instrument at other voltage range, please contact us.
2.4 Power On/Off and Door Release
1) The power is provided via earth leakage breaker switch which is attached on the left
side of the device. Connect the power cord properly and turn on the earth leakage
breaker and the power is on, the latest setting value recalled with beeping sound.
2) Press the ‘Door’ button on the control screen to open the door.
3) Remove the protection materials inside the chamber.
4) Mount the rotor, close the door and turn off and on the instrument again for
proper operating.
Auto-Door Lock
The door should be closed only by gentle press-down motion
2.5 Emergency Door Open
1) Turn off(on) the instrument by pressing a switch off(on) the left side of the
machine.
2) Open the door using emergency door open function (with T-wrench).
3) Remove the (protection) materials inside the chamber.
4) Mount the rotor, close the door and turn on the instrument again for
proper operating.
* After mounting rotor, you can use ‘DOOR’ button to open the door.
