Boot and Transfer Plate Installation
NOTE: Installation of the boot is the same whether the tank has the standard collar or the Sure-Flo
Feed Flow Control.
Slide the boot as far as possible into the tank collar or the Sure-Flo Feed Flow Control opening.
(See Figure 1.) Align the boot with the Flex-Flo System that will be installed. Using the holes in the
collars for guides, drill eight (8) 11/32" holes into the boot rim. (See Figure 2.)
Mount the boot to the collar with the hardware provided. Bolt the Transfer Plate and Unloader Braces to
the boot as shown. See Figure 3 for proper usage and assembly direction of hardware for mounting the
boot and the transfer plate. All connections should be tightened until they are “snug”.

(See Figure 4.)
Bolt unloader to transfer plate/unloader brace assembly as shown in Figure 5. Note orientation of these
bolts. (See Figure 5.)

Restrictor Adjustment
The restrictor may be adjusted to allow more feed flow. Do not modify the restrictor until the system is
completely operational and the auger has been polished by running feed through the system.
Instructions:
1. Remove the restrictor tube from the unloader.
2. Cut 1" (2.5 cm) from the restrictor. (See Figure 7.)
3. Install the restrictor and the bearing assembly into the unloader.
4. Test the feed flow.
5. If the desired feed flow rate is not attained, repeat the above procedure until the desired rate
is reached.
