Operation

Preparation

Install the rotor according to directions in the rotor manual.

a. Ensure that the rotor is seated on the drive hub.

b. Securely attach the rotor lid knob, or tie-down knob in rotors without lids, to the drive

shaft by turning it to the right (clockwise).

NOTE

If the knob turns loosely and you do not feel threads engaging, the rotor drive hole pins may

not be properly seated on the centrifuge hub. Lift the rotor up above the hub, rotate it slightly,

and lower it onto the hub again. Tighten the knob.

c. Avoid bumping the control panel keys during rotor installation or removal.

d. If you bump the control panel and an

L1 diagnostic appears, press CE to clear the message.

CAUTION

Rotors used in Avanti J series centrifuges must have drive pins in the rotor drive

hole. These drive pins engage with the centrifuge drive hub to ensure that the

rotor does not slip during acceleration. Some Beckman Coulter rotors were

originally manufactured without drive pins because these rotors did not need pins

to run in older model centrifuges. To check for drive pins, hold the rotor up or turn

it on its side and look into the drive hole. If you do not see at least two metal pins

near the top of the hole, do not use the rotor in the Avanti J-E.

Close the chamber door and press DOOR.

The door latches.

When the latches engage, the LED next to the

DOOR key lights.

To keep the chamber clean and dry, leave the door closed whenever possible.
