3.4. Emptying Flexel 3D 1000L Bags
Sartorius Stedim Biotech recommends the
dispensing through the bottom.
a) Take the bottom port tube and position it
vertically. Open the connector protective
outer-wrap using the reversible cable tie
on the dispensing line and carry out the
connection according to the standard
procedures that apply on the site
(See Fig. C).
b) Open the clamp (See Fig. A). Drain the
bag - Gravity can be used, but for faster
draining Sartorius Stedim Biotech recom-
mends the use of a peristaltic pump.
(See Fig. 17)
c) The bag collapses as it is drained. The
sloped bottom of the Palletank
position of the drain hole, provide nearly
100% fluid recovery. This efficiency can
be improved by lifting the bag at the end
of the operation. (See Fig. 18)
d) When the dispensing is complete, clamp
the line (See Fig. B) and disconnect the
main drain line from the dispensing tube
®
of the Flexel 3D Bag.
e) Open the bottom gates by removing the
retaining clip from the retaining clip fas-
tening point; then grasp the retaining
clip fastening point and swing the
bottom gates open (see Fig. 7).
f) Lift the collapsed bag and remove it from
®
the Palletank (See Fig 18).
g) Discard the Flexel ® 3D Bag in accordance
with the procedures used on your site.

4. Troubleshooting Guide

The bag will not fill.
> Check the clamp is open and the tube is
not pinched.
