• The felt ring that seals the bearing openings must be fully soaked with oil to provide in a particular
case a sufficient protection against leaking liquids.
Clean centrifuge and accessories as follows:
1. Open the centrifuge.
2. Turn off the centrifuge.
3. Pull out the power supply plug.
4. Remove the rotor according to the rotor manual.
5. Remove the centrifuge tubes and adaptors.
6. Use a neutral cleaning agent with a pH value between 6 and 8 for cleaning.
7. Dry all of the rotors and accessorie after cleaning with a cloth or in a warm air cabinet at a
maximum temperature of 50°C.
8. Clean the housing of the centrifuge as needed.
• After cleaning, treat the entire surface of aluminum parts with corrosion protection oil (7000
9824). Also treat the cavities with oil.
• Treat the bolts of the swing out rotor with bolt grease (75003786).
After some applications their might be ice in the rotor chamber.
To defrost the chamber:
1. Install a rotor and close the centrifuge.
2. Set run parameters to SPEED=2500 rpm, TIME=5:00 (longer for heavy frost buildup),
TEMP=30.
3. Press the START key.
Clean the rotor chamber as described above.

CAUTION Observe that no liquids, particularly no organic solvents, get into the openings
at the motor shaft outlet, as they could leach out the grease of the bearings.
CAUTION Lift the rotor with two persons due to its weight.
CAUTION When cleaning, do not allow liquids, especially organic solvents, to get on the
drive shaft, the bearings, or the locks.
Organic solvents break down the grease in the motor bearing. The drive shaft could freeze
up.
