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
(closer to you). Notice that the pin
(see arrow in the figure above)
protruding from both sides fits in the
slot at the bottom corner of the
pump head.
When placing the backer into
position, squeeze it against the
tubing so that its holes line up.
Once the backer is in position, push
the two quick release pins part way
into the pump head—enough to
capture the narrow backer but not
too much to interfere with the wide
backer sliding into place.
The two spacer blocks (circled) should
rest on the sloping sides of the pump
head and the pins in the backers (white
arrow) need to slide into the slot at the
bottom of the pump head.
Next, place the wide backer behind
the tubes on the wide roller, with
the protruding pin pointing towards
the narrow backer. If the backer
does not seem to fit, check that the
ring-tabbed pins are not in too far
and interfering with the backer. If
they are, simply slide the pins out
until they do not protrude into the
wide roller section. While squeezing
the backer against the tubing, firmly
push the ring-tabbed pins in all the
way, i.e. until the rings touch the
pump head.
Once the wide backer is in position,
push the pins in all the way, until
the rings touch the pump head.
