7 The corrugated pipe is led out of the tank with
the bending support (as described on Datasheet
BGT 1.800)
The BIOFLEX connector lies outside the tank. The wel-
ded-on wall duct lies inside the tank wall. For installation
instructions for the leading out of the BIOFLEX pipe with
its connector and gasket insert, see Figs. 10 to 47.

into the tank
Push the double nipple into the opening of the steel tank
or the core hole of the tank. In the case of a concrete tank
also push in the gasket insert from outside and fit it in the
correct position (pointing to the external wall of the tank).
Screw on the flange plate.
Attention! The screws delivered with the pipe work may
only be used in tanks with a wall thickness of at least
120 mm! Permanently elastic insulation material
(e.g. Sikaflex) must be fitted between the tank wall and
the flange plate.
After this, screw the elbow screw fitting with the rigid com-
ponent to the double nipple. Position the last support. The
pipe should lie horizontally to the elbow screw fitting.
Mount the end connector, aligning it correspondingly.
For installation instructions for the BIOFLEX pipe end con-
nector see ISI 8.86.01 to ISI 8.86.04.
Finally, connect the pipe work with the elbow screw fitting.
For the final installation of the gasket insert, see Figs. 46
and 47.
