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.
Installing the Tube Set
Place the rear of the instrument so
that it faces you. The end of the
tube set with the luer lock fittings
should be on the left, the end which
connects to the bottles on the right.
Line up the tube set so that the end
of the manifold with the tubing
running to the containers is nearer
the rear panel.
Place the pairs of tubes on the
rollers. The rectangular spacer
blocks holding the tubes at the
correct spacing should fit nicely on
the pump head. Notice how the
gray blocks in the top left and top
right in the following figure rest on
the sloping sides of the pump head.
Of the two black plastic boomerang-
shaped backer pieces, the thinner
one should be installed first, and
more to the rear of the instrument
