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.
•
The 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 1/8" hex key 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 shaft cross-
pin with the rotor hub. Tighten the rotor screw to 3.5 Nm.
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.
7.4. Rotor Screw
•
If the rotor screw needs to be tightened, use a 1/8" hex key and tighten to 3.5 Nm.
7.5. Speed Calibration
•
Check the centrifuge speed periodically, every two years is recommended.
•
Important: When verifying rotor speed, make certain that all carriers are installed
in the rotor.
•
No calibration adjustment of speed can be made, only a verification of rotor speed.
