Page 7: Important Information
GENERAL INFORMATION 1. IMPORTANT INFORMATION The following general instructions, and the precautions regarding the prevention of corrosion in rotors and accessories, as described under MAINTENANCE, must be noted and carefully observed. The maximum load should always be checked before commencing any operation. If the sample has a relative density greater than 1.2, the maximum permissible speed of the rotor should be calculated as given in this publication, and applied. -

OPERATION 5. OPERATION 5.1 Run Procedure Ensure that the Rotor is correctly loaded and secured and the Timer set at Off. Close the lid and press down firmly. Press the Power switch on. The Power On and the Lid Unlocked indicators will come on. Select Timer to Hold, for continuous running, or to the time required. -
Page 22: Lid Safety Circuit
OPERATION 5.6 Lid Safety Circuit The Lid Safety Circuit has a dual function: It prevents power being switched to the motor until the lid is properly closed. It imposes a delay of approximately three and a half minutes in the event of a tacho failure before the Lid Unlocked indicator comes on and the lid can be opened. -
Page 23: Maintenance
After use wash rotors, metal buckets, cups, carriers and adaptors in warm soapy water, dry and store, inverted, in a dry place. Rotors should be protected with MSE Rotor Spray (Cat. No.17341.151), which is an anti-corrosion and de-waterising agent. -
