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

Fold the channel in half.
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.

out the top.
Note: Channels with an LRS chamber: DO NOT pull on
the tubing connected to the LRS chamber. This can damage
