RISER/CONVERSION KIT INSTALLATION
All large Fusion ® units are shipped without risers attached due to size restraints, therefore all units will need to have the chosen riser kit attached in the
field. Please see the riser installation instructions below. Risers come in size ranging from 6 inches to 3 feet, under no circumstances can the risers be
extended more than 3 feet.
Riser Installation Instructions – All Large Units
Install Fusion ® unit in the ground and fill with water checking for any leaks. Backfill with dirt up to a reasonable working level for safety and ease of
installation of hub inserts and risers. Be careful not to get any backfill material into Fusion ® unit.
Hub Inserts for 4” Schedule 40 PVC
The Fusion ® unit will have the Japanese pipe size hub inserts. You may need to change them out to the American 4” PVC schedule 40 pipe size.
24” Riser Installation Process
Verify tank opening and riser match up by placing the riser over the chosen access hole. Once it is verified that the riser fits, proceed. (if it does not fit
cut tank opening to match ). Clean tank lip of any dust and dirt and apply provided tar rope seal to tank lip. Install riser by setting and pressing into the
tar rope seal adhesive. Additional fasteners may be used to attach riser if needed. If
used, seal fasteners with silicone so they are watertight. Install riser cover with included
tamper-proof screws.
Rectangular Riser Installation Process
ZFL-2800 thru ZFL-4000
Place rectangular riser over the rectangular opening, make sure the flange with
threaded inserts is facing up and the open holes side goes against the Fusion ® unit.
Lineup the inside of riser opening and the inside of tank opening, riser should lay flat
on tank with little over hang. Trim Fusion ® opening now if necessary.
Mark and pre drill the Fusion ® unit to match the supplied rectangular riser. Clean
off any dust and
dirt and apply
tar rope seal
adhesive to the
top lip of the
Fusion ® unit.
Carefully align
the riser and place into the tar rope seal adhesive and bolt down with supplied
nuts, bolts, and large fender washers being careful not to over tighten. If there
is excess overhang from the riser or it is felt that there isn’t enough support for the
riser, the use of “L” brackets ( 90 degree brackets ) may be used. Place one “L”
bracket in the center bolt hole on each side of riser, attach with nuts, bolts and large
fender washers. Mark and pre drill the Fusion ® tank, apply a liberal amount silicone
around each of the pre drilled holes and attach with supplied nuts, bolts, and large
fender washers being careful not to over tighten.
Mark and pre-drill the remaining riser bolt holes into the Fusion
® unit. Apply a liberal
amount of silicone around each of the pre-drilled holes and then attach with supplied
nuts, bolts and large fender washers being careful not to over tighten.
