Removing the Tube Set
First, detach the tube set from the
aspiration head by disconnecting the
luer lock fittings. Now detach the
tube set from the buffer, waste, and
reagent containers by disconnecting
the quick-connect fittings from the
bottles by pressing the metal clips
on the fittings, as explained in
“Changing Bottles”
Turn the instrument around so that
the rear of the FREEDOM ROCKER™
is facing you and the entire
instrument rests on a level surface.
To remove the tubing from the pinch
valve, use Manual Mode and have
the instrument FILL or DRAIN a
volume of 0 ml to the container with
the matching color to the tubing you
want to insert or remove. DO NOT
ROTATE THE PINCH VALVES BY
HAND. You must also pivot the
tubing retainer plate out of the way
to remove the tubing. The retainer
plate hangs in place under gravity,
so you can simply push it to the
side.
It helps to pull gently on the tubing
so that it stretches and becomes
narrower.
The wide boomerang-shaped backer
drops out when the quick release pins
are pulled halfway out.
Next, pull the two pins with the ring
tabs halfway out, as shown in the
figure below. The wide boomerang-
shaped backer will drop out, as
shown in the figure. Next, remove
the pins all the way out and the
narrow backer will also drop out.
Lift up the FREEDOM ROCKER™ if
necessary to completely remove the
backers from the pump head.
Finally, remove the tubing from the
pump head by gripping the gray
spacer blocks, as shown in the
following figure.
Pull lightly on the two tubing spacer
blocks (gray) to remove the tubing
from the pump head.
