MA709H
By moving the Window Plate, Cover Plate, Tube Anchor, Level Switch Assembly, and Power Unit, it is
possible to extend the system in a straight line or use the Extension Boot to replace elbows making a 90 degree
turn where that is convenient.
The Safety Switch should be located toward the outlet end of the boot on all applications.
Figure 1 through Figure 4 show that by moving several components to different locations the Extension Boot
may be used to turn right hand, left hand, or extend a straight line system.

1.Attach the (incoming) Tube Anchor to the Extended Length Boot, using hardware supplied.
Place a Tube Clamp on the Tube Anchor.
2.Mount the Power Unit on the Boot, using 5/16-18 hardware supplied.
3.The Extension Hopper should be located near the center of the auger line to balance the load on the systems.
Suspend the Extension Hopper/Power Unit from the ceiling. The Extension Hopper, Power Unit, and feed
will weigh approximately 90 pounds (40.1 kg). Adequate support must be provided to prevent sagging at the
Extension Hopper location.
Support the Boot securely, using the “ears” on the Power Unit, chain and screw hooks to suspend the
