assembly contains a solenoid and limit switch that are used to
determine the state of the lid (Open or Closed) and to keep the lid
locked during centrifugation cycles.
Rotor: The centrifuge rotor is the main
component that spins in the centrifuge. The rotor is loaded with
tube holders, and the samples are placed into the tube holders for
processing.

Warranty Information:

Drucker Diagnostics warrants its centrifuges to be free from
defects in workmanship and parts for two years.

Troubleshooting:

Problem: The lid does not open.
Possible Cause: No Power
Solution: Check line cord. Check wall outlet.
Rotate the lid knob fully clockwise before pressing the OPEN’ button. Press theOPEN’ button to de-activate the lid. Requires
service.
Problem: Excessive vibration
Possible Cause: Rotor improperly loaded
Solution: To gain access to the rotor – Remove the
`OPEN/CLOSE’ sticker and slide the lid latch lever toward the front
of the centrifuge. This will unlock the lid.
Problem: Rotor does not spin
Possible Cause: No Power
Solution: Requires service.
Problem: Clicking noise during braking
Possible Cause: Lid not properly latched
Solution: Requires service.
Problem: Whistling noise while running
Possible Cause: Rotor is loose
Solution: Requires service.

Frequently Asked Questions (FAQ):

Q: How often should I clean the centrifuge rotor?

A: It is recommended to clean the centrifuge rotor after every
use to prevent debris buildup and ensure optimal performance.

Q: What should I do if the centrifuge makes a loud noise during

operation?

A: If the centrifuge is making unusually loud noises, stop

6 SERVICE INSTRUCTIONS
6.1 Cleaning
a) Use appropriate Personal Protective Equipment (PPE)
b) The cabinet, rotor top and accessories shall be thoroughly cleaned using soap and water, isopropyl alcohol, or a mild bleach solution.
c) Apply cleaning solutions with a dampened towel or cloth ONLY. Do not spray or pour cleaning solution directly onto or into the centrifuge. Do not saturate or submerge the centrifuge in water or other cleaning solutions as this will cause damage, create a safety risk; and void the warranty.
d) Under no circumstances should any of the following be used: Fully/Partially Halogenated Hydrocarbons, Ketones and Esters.
e) Use of any chemicals not prescribed by the manufacturer may cause damage to the rotor and tube carriers / holders and shall not be used.
6.2 Maintaining the Rotor
a) Keep the rotor clean; any corrosive materials must not be allowed contact with the rotor and should be cleaned immediately.
b) The rotor should be checked periodically for signs of wear.
c) Remove the rotor from service if any of the following are found: cracks, deep scratches, corrosion or discoloring.
6.3 Rotor Screw
a) If the rotor nut needs to be tightened, use a 1/8″ hex driver for horizontal rotors or 5/32″ hex driver for fixed angle rotors and tighten by hand until snug.
6.4 Speed Calibration
a) Check the centrifuge speed periodically, every two years is recommended.
b) Important: When verifying rotor speed, make certain that all tube holders are installed in the rotor.
c) No calibration adjustment of speed can be made, only a verification of rotor speed.
6.5 Removing the Cabinet (Upper Housing)
a) There are nine screws that fasten the centrifuge cabinet to the base.
b) Begin by unplugging the centrifuge and waiting 10 minutes for internal voltages to dissipate.
c) Use a #2 Phillips screwdriver to remove the cabinet screws (three on the back, six on the underside).
d) The centrifuge control panel is attached to the base internally with cable harnesses. Be careful not to stress the cables when removing the cabinet.
