3. Introduction
Applications
In poultry application, Flex-Flo Fill System conveys feed from bulk feed tank to hoppers inside the po ultry
building as shown in Figure 3A. Other feed systems (i.e. cycle plus, chain feeder etc.) take the feed from
the hopper to the desired locations in the building. On this layout, hopper level switches may be placed in
more than one hopper to assure that no hopper empties before the control unit hopper requires feed.
(All switches must be wired in parallel so that any one switch can start the system.)
Figure 3A Poultry Application Layout
In swine applications, Flex-Flo Fill System conveys feed from bulk feed tanks to each individual fe ede r
(i.e. S.S. hog feeder, drop feeder etc.) directly as shown in
consumed. A feed level control is installed at the end to shut off the system after all feeders are filled.
Figure 3B
. It is at this location that feed is being
Figure 3B Swine Application Layout
Background
The Flex-Flo Fill System consists of a combination of PVC tubes and preformed PVC elbows. A special
PVC cement is used to connect the tubes and elbows. The PVC tubes are available in four (4) different
sizes. The PVC tube contains a rotating auger which conveys the feed to the different outlet holes.
The auger is driven by a direct drive power unit or a belt drive power unit.
Building Safety
If you are intending to install the Flex-Flo System at high levels and/or suspended from a building
structure, it is important that you check the structural integrity of the building to carry the additional load.
For information on the imposed loads on the building by the Flex-Flo System, please contact the dealer or
the GSI group.
Installation Sequence
This manual outlines the recommended order for the installation of the Flex-Flo System. Following this
guideline will provide the safest and easiest method of installation. Above all, connection of the system
to the electrical mains should be the final stage of installation. Failure to observe this could lead to a
fatal accident.

The Feed Tank Connections
Feed Tank Orientation
Positioning the feed tank in line with the Flex-Flo System will provide the most trouble-free operation possible.
Avoid unnecessary elbows and curves to ease system installation. A feed tank with a 30° unloader is
generally required to be at least 10-1/2' (3.2 m) away from the building. With a straight un loa der, the tank
will be approximately 4' (1.22 m) farther away from the building in order to make auger tube connections.
The reference points are based upon the height where the system enters the building. Different unloaders
with various elbows and curves used provide different entrance opportunitie s. The distanc es are ach ie ved
by modifying and adjusting the elbows and tubing as needed. See tables
on Page 13
(Metric) for tank placement recommendations.
