LABEC Z-L-450 - Manual (Page 7)

● Stop it while speeding.
● When the rotating speed of the rotor is over 250r/min of setting speed, the machine will give an alarm;
When the rotating speed is over 300r/min of maximum rated speed of the rotor, the rotor will stop to
rotating automatically and you can open the door until the rotor stops totally. And restart it after trouble
clearing.
● Open the door when it's emergency
If there is power failure suddenly or there is trouble when the rotor is rotating, and you can't open the door
by pressing keys, please open the door manually (please check troubleshooting for more details)
2.4 Requirement of placing the machine
2.4.1 The device should be placed in horizontal table-board with sufficient rigidity, and it should be far away
from vibration shock device. Keep it away from heat and direct sunshine.
2.4.2 There should be space of 10cm to 15cm around the centrifuge for the ventilation of the machine.
2.4.3 Adjust it after installation, and make the 4 supporting legs of the bottom of the machine support the
machine evenly.
2.4.4 The scope of equipment supply AC220V 50HZ/60HZ.
The machine must be totally grounding and power ground lead should be
connected to ground lead of electricity grid. Don't cut the electricity when
the rotor is running, or it will damage the control circuit.
3 rd Preparation before Using
3.1 Transportation and installation
Low-speed centrifuge of general air-cooled is transported with packing container with buffer protective
materials inside. When you open the package, please remove the buffer materials.
The net weight of the machine is 15 kg. Please lift the machine from left and
right sides balanced. Please move it vertically and don't swing it.
For long-distance transportation, please use special packing chest and fix it firmly and keep it vertically.
Please handle with care.
3.2 Choose proper place to place
Low-speed centrifuge can only be used indoors, and the requirement for placement is as following:
● Keep 30cm safe distance for the centrifuge, and don't put any hazardous substances or let anybody stay
within 30cm around the machine.
● Please fix the bracket of the machine and don't swag. If you are using removable brackets or trolley,
please ensure that there is locking device for the brackets or trolley for the safe-using of the centrifuge.
● If you put the centrifuge in the wall or corner, please make sure there distance from the wall to the
posterior is 10cm and from the wall to the left and right sides is 15cm, It's good for air circulation and heat
elimination.
● Centrifuge should be keep far away from the windows to avoid origin of heat and direct sunlight.
● After placement, 4 supporting legs of it should sustain on the table-board evenly and adjust the level.
● The environmental temperature for the room keeping the centrifuge should be between 5º~40º, and the
environmental humidity should be ≤80%. Please keep the environment clean.
3.3 Put the machine at fixed place
Once the centrifuge is placed, don't move it discretionarily. If you move it, please re-confirmed or re-adjust,
and make the 4 supporting legs sustain evenly on the table-
board, ensure that the mounting bracket and the table-board are fixed and don't swag.
3.4 Connect the power correctly
Please use power cord separately for the centrifuge. And make sure of that the cord is grounded well and
the power cords of the centrifuge meet the safety requirement of the country or the region. The supply
