Operation Guidelines
1. Open the unloader slide completely for the delivery system operation except on tandem system.
2. Do not operate the Flex-Flo System empty. Utilize a time clock with the system whenever
possible because:
A. It lessens short cycling by operating on a set schedule versus on demand.
B. It prohibits the system from running excessively when empty if the tank should go dry. When the
optional unloader switch is used, it should be wired so that if the feed tank goes empty the power
unit will stop.
3. The time clock should be programmed to start the Flex-Flo System often. By running the system
often, long running periods are eliminated and the feeders are kept full. When the Flex-Flo System
is used for filling poultry feeders, a time clock should be utilized to ensure that all feeders are filled
at the same time. The Flex-Flo System will have a better opportunity to keep up. Position the hopper
level control low in the last hopper.
4. A safety switch is provided on the control unit to trip out the motor in the event that feed is packed
inside. If feed does get packed, dislodge the feed from the drop tube and clean-out the inside of the
control unit which will allow the switch to close. The hopper level control needs to maintain vertical
positioning to keep the paddle swinging freely. Check the adjustment regularly. The control unit
safety switch does not replace the hopper level control.
5. When the Flex-Flo System is used to convey high-moisture feed, the auger line should be completely
emptied after each running to prevent feed from jamming in the tubes.
6. Operate the manual outlets several times each week to free them of feed debris.
7. The restrictor on the unloader anchor controls the feed that is flowing into the auger. When starting
a new system, the restrictor should be installed at full length and flush with the front of the unloader.
Permit the system to polish out the inside of the tubing before modifying the feed flow. When the
restrictor tube is in the unloader, maximum restriction is reached. When increased feed flow is
desired, the length of the restrictor tube should be decreased.
