7. SERVICE INSTRUCTIONS
7.1. Cleaning
•
The cabinet, rotor and accessories can be cleaned using soap and water, isopropyl
alcohol, or a 10% (5500 PPM) bleach solution
•
Apply cleaning solutions with a towel or cloth. Do not submerge the centrifuge in
water or other cleaning solutions as this will cause damage and void the warranty.
•
Under no circumstances should any of the following be used: TBQ Germicidal
Products, Fully/Partially Halogenated Hydrocarbons, Ketones or Esters.
•
Use of any chemicals not prescribed by the manufacturer may cause damage to the
rotor and tube carriers and shall not be used.
7.2. Removing the Rotor
•
Use a 1/2" nut driver to loosen the center rotor screw (turn counter-clockwise).
•
Lift the rotor straight up and out of the rotor chamber.
•
To install the rotor, reverse steps A and B above.
•
Take care to align the hub spines with the rotor hub.
•
Tighten the rotor nut by hand with a ½" nut driver until snug. A good rule of thumb
is one full thread showing above the nut is a good indicator of proper installation.
7.3. Maintaining the Rotor
•
Keep the rotor clean, any corrosive materials must not be allowed contact with the
rotor and should be cleaned immediately.
•
The rotor should be checked periodically for signs of wear.
•
Remove the rotor from service if any of the following are found: cracks, deep
scratches, corrosion or discoloring.

SOLUTION
Correct the imbalance
Check wiring
• Check sensor in lid locking tray
assembly
• Check reflective tape on rotor
Check for missing tube holders
• Check for missing tube holders
• Check the lid and guard bowl
gaskets. Voids in the rotor
chamber gaskets change the
airflow, resulting in increased
stress on the motor drive
