Drucker Diagnostics Model 653ES Centrifuge - Manual (Page 6)

Operation:
NOTE: Follow the initial setup procedure on page 4 before initial operation.
1. If the centrifuge is not plugged in, plug it into an approved 115 Volt A.C., 60 Hz.
outlet. The centrifuge performs a warm-up process at power-up that takes
approximately 50 seconds.
2. Push the ‘OPEN / EMERGENCY STOP’ button and then open the lid.
3. Insert cushions (if needed) into the tube carriers for the tube size you are
using. Refer to ‘Tube Carrier Configurations’ (page 8) for assistance.
4. Place the test tube samples into the tube carriers. Be sure to follow the
rules for balanced loads.
5. Close the lid and turn the lid knob clockwise to its complete stop position. The
’LATCH’ indicator light should turn on to indicate that the latch is closed
properly. If the lid knob is not completely latched, the ‘LATCH’ indicator
light will not turn on and the centrifuge will not operate!
6. Set the time desired buy using the up/down buttons next to the display.
7. Turn on the machine by pushing the ‘START’ button on the control panel.
8. The centrifuge should begin to spin. The ‘RUN’ indicator light should
illuminate.
IF A PROBLEM IS FOUND DURING A SPIN THAT REQUIRES THE CENTRIFUGE TO
SHUT DOWN, PRESS THE ‘OPEN / EMERGENCY STOP’ BUTTON !
9. After time has elapsed, the ‘RUN’ indicator light will extinguish and the rotor
will slow to a complete stop.
10. The ‘UNLOCKED’ indicator light will illuminate and the locking mechanism
will disengage allowing entry into the rotor chamber. If it does not, refer
to page 10 on troubleshooting.
11. Turn the lid knob counterclockwise and open the lid.
12. Remove the samples.
13. If the machine re–locks before the samples are removed, press the ‘OPEN
/ EMERGENCY STOP’ button to unlock the lid for an additional fifteen (15)
seconds.

BALANCED LOADS
Your centrifuge must contain a balanced load in order to work properly.
Use the following rules when loading the rotor.
Spinning balanced loads will extend the life of the machine and
produce better results.
1. Opposing tube carriers must be identical and must contain the same
cushions, or none at all.
2. Opposing tube carriers must be empty or loaded with equally
weighted samples.
3. If an odd number of samples is to be spun, fill a tube with water to
match the weight of the unpaired sample and place it across from this
sample.

Rotor Removal and Installation:
To remove the rotor:
1. Unlock the centrifuge by pushing the ‘OPEN / EMERGENCY STOP’ button
and unlatch and open the lid.
CAUTION: Unplug the centrifuge from the electrical outlet at this time to
eliminate the possibility of electrical shock or other injury.
2. Remove the test tube carriers.
3. Remove the knob in the center of the rotor by turning it counterclockwise, (a
tool may be required).
4. The rotor is sitting on a cone-shaped adapter. Pull the rotor up and off of
this adapter.
Before using any cleaning or decontamination methods except those
recommended by the manufacturer, users should check with the manufacturer
that the proposed method will not damage the equipment.
The rotor chamber, rotor and accessories shall be thoroughly cleaned using
either isopropyl alcohol, soap and water, or bleach. The use of Fully/Partially
Halogenated Hydrocarbons, Ketones, Esters and all other chemicals not
prescribed by the manufacturer may cause damage to the rotor and tube holders
and shall not be used.
To install the rotor:
1. Place the rotor back onto the cone-shaped adapter. You may
need to turn the rotor slightly to line it up properly.
2. The rotor should slide onto the rotor cone freely.
3. Once a proper fit has been achieved, replace the rotor knob
and turn it until it is hand-tight, (a tool may be required).
4. Replace the tube carriers and verify that they are seated
properly.
5. It is recommended that the initial setup procedures be
performed to ensure that the rotor has been installed correctly
and that no damage has been done to the centrifuge during
either the rotor installation or possible rotor chamber cleaning.
See page 4 for this procedure.
Programming Functions:
END OF RUN INDICATOR: At the end of a cycle, the unit can be programmed
to beep to inform the operator. While the centrifuge is running (the green RUN
indicator light is on) press and hold the START until a beep is heard to toggle the
current setting. One beep means that the indicator is disabled, two means it is
enabled.
DIGITAL CYCLE COUNTER: While the centrifuge is idle, open the lid. Press
and hold the START button for approximately 5 seconds. The current cycle count
of the unit will be shown on the display and will remain until the START button is
released.
