Planning The Model 108 Feed Delivery System - Chore-Time FLEX-AUGER 108 Installation Instruction

FLEX-AUGER® Feed Delivery System

Planning the Model 108 Feed Delivery System

Carefully plan the Model 108 Fill System installation. Make sure the system will not interfere with other
equipment, doors, windows, etc.
The charts below provide power unit recommendations and maximum system line lengths. The top chart applies
to standard 348 RPM systems. The lower chart applies to (optional) High Capacity 425 RPM systems.

*Maximum line lengths should be reduced for elevations over 8' (2.4 m) and/or inclines steeper than 45 degrees.
Maximum lengths for 108 systems include use of two PVC elbows. If additional elbows are used, decrease line
length by 30 ft. (9 m) per elbow. Length of extension systems do not include elbows. Decrease maximum
extension system lengths by 30 ft. (9 m) per elbow if used in the system.
Horsepower requirements are based on length of the Model 108 FLEX-AUGER system and type of system
installed--i.e. number of turns.
See "Model 108 Bin Placement Chart" on page 14 through page 18 for typical bin to building placement using
various elevations, boots, and screener options.
1.For the easiest installation and most trouble-free operation, locate the feed bin in a direct line with the FLEX-
AUGER Feed Delivery System. The layout charts "Model 108 Bin Placement Chart" on page 14 and
"Model 108 Bin Placement Chart (with In-Line or Rotated Screeners)" on page 15 provide some points
of reference for bin placement according to the height at which the FLEX-AUGER tube enters the building.
Remember, these are only examples. The layouts can be modified by changing the elbows, the tube sections,
and/or the distance from the bin to the building.
FLEX-AUGER Feed Delivery Systems operate best at an angle of no more than 60 degrees from horizontal
to the entry of the building at the desired height. Chore-Time considers a 45 degree elevation to be standard.
The lower the angle, the more reliable the system.
2.Lay out the system as straight as possible. Avoid extra elbows and curves by locating the feed bin in line with
the feeders. One horizontal 90 degree turn is permissible inside the building. 180 degree turns are not
recommended under any conditions.
If additional turns or elbows are required, use an Extension Boot. Remember: one 90 degree elbow requires
the same power as 30' (9.1 m) of straight line.
3.Plan the system so that the auger tubes are directly over the feeders or hoppers to be filled, if possible. The
drop tubes may be angled to a maximum of 45 degrees from the vertical if necessary. At angles greater than
45 degrees, bridging in the drop tubes may occur.
