Inlet Hopper with Flex-Duct
1. Lift the collector high enough to assemble.
2.
Apply sealant around the flex-duct collar toward the outside of the bolt pattern.
3.
Align the flex duct collar with the bottom flange of the hopper. Fasten using bolts, washers, and hex nuts supplied.
4.
Apply sealant around the hopper’s top flange toward the outside of the bolt pattern.
5.
Align the top flange of the hopper with the bolt pattern on
the bottom of the collector and secure using 6mm bolts and
washers supplied.
Note: Install a 6mm bolt into every rivnut.
6.
Fasten one end of the flexible duct to the collar using a six
inch hose clamp.
7. Position the inlet collar on the machine center and trace the
inlet opening and bolt pattern. Remove inlet collar, cut inlet
hole, and drill bolt holes using a 3/16-in diameter drill bit.
8.
Apply a 1/4-in bead of sealant to the machine center, toward
the outside edge of the bolt pattern.
9. Align collar and fasten to machine center using 1/8-in
customer-supplied bolts, washers, and hex nuts.
10.
Trim the flexible duct to the required length and secure with
remaining hose clamp.
Do not allow flexible duct to create a
P-Trap. See Flex-Duct Positioning.
