Lid release
Once the run has been completed and the rotor come to a stop, the lid will open
automatically. If the lid does not open automatically, press the lid button. Note
that the lid button will not operate while the rotor is spinning.
WARNING: Do not attempt to open the lid of any centrifuge until the rotor
has come to a complete stop.
In the event of a power failure or malfunction, it may be necessary to open the lid
manually.
1. Disconnect the power cord from the wall socket.
2. Remove the plastic plug, located on the left side of the unit, below the quick
button.
3. Pull the cord (attached to the plug) to open the lid lock manually.
Lid lock
The centrifuge can be started only with the lid securely closed. When the rotor
begins to accelerate, the lid lock indicator light turns on and the lid button
becomes inoperable. Do not attempt to open the lid until the lid lock indicator
turns off. At the end of the run, the lid will automatically open.
Speed selection
The speed (rpm) can be selected to 14,000rpm with the knob labeled “speed”.
The scale is directly proportional to the speed - a setting of 9 corresponds to
9,000rpm, a setting of 13 corresponds to a speed of 13,000rpm, etc.
Selection of operating time and momentary operation
Operation of the centrifuge begins when the timer knob is turned clockwise to set
a run time. For run times less than 5 minutes, turn the knob clockwise past the
halfway point and then counterclockwise to the desired time. For run times longer
than 5 minutes, turn the knob clockwise to the desired time.
When the preselected time expires, the centrifuge will stop automatically. To stop
the centrifuge prior to the expiration of set time, turn the timer knob to the zero
position.
The centrifuge may be operated manually by pressing and holding the quick
button. The centrifuge will continue to run as long as the button is depressed.
Some models are equipped with a timer that includes a hold position. Continuous
operation of these models may be achieved by turning the timer knob firmly to
the left. The centrifuge will continue to operate until the knob is turned to the zero
position.
Note: The timer knob may be turned in either direction during operation of the
centrifuge without damage to the timer mechanism.
