Rotate the centrifuge so the loading port is open to the front.
Ensure the centrifuge collar holder rests on the outer rim of the
filler. (See position of centrifuge collar holder in Figure 4-1 on
page 4-3.) If it is not in the correct position, push the filler latching
pin toward the center of the centrifuge, raise the filler latch, and
place it on the outer rim.

Gently extend the tubing connected to the channel to full length to
ensure it is not twisted. Do not unseat the bearings.

Insert the folded channel through the lower loading port and pull it
out the top.

Position the channel in the correct orientation above the filler slots
before placing the centrifuge collar (Figure 4-11) into the centrifuge
collar holder. The red tube should be on the right. Ensure the
tubing is not twisted.

Note: During set-up, verify that all luer connections are secure.
Note: Channels with an LRS chamber: Ensure the
LRS chamber is sandwiched between the folded
portions of the channel. Be careful not to stretch the
tubing.
Note: Channels with an LRS chamber: DO NOT pull on
the tubing connected to the LRS chamber. This can damage
the LRS chamber.
