1.
Excavate an area large enough for the Fusion
Excavation dimensions are calculated by adding 12-18" (305-457 mm) to the length and width of the Fusion
proper backfilling.
2.
Construct a 6" (152 mm) thick stone pad of either 1/4" - 1/2" (6-13 mm) diameter stone or concrete pad and level to within 1/8 inch (3 mm).
3.
If the unit is not level, it will cause uneven water flow as well as unbalanced aeration, which will result in poor performance.
4.
Gently lift the unit at all four lifting points with a harness and install it on leveled stone pad (Figure 8).
5.
Check unit to make certain it is level by placing a level at several locations on the riser. (riser covers removed) (Figure 8).
BACKFILLING
1.
If groundwater is present, anti-flotation measures must be used to
stabilize the unit prior to backfilling. Please follow the procedures in the
Anti-flotation section to properly anchor the Fusion
2.
Fill the unit with clean water to the normal operating depth prior to
backfilling. Partition walls between chambers are water-tight and will
fill in succession beginning on the inlet side of the unit. Therefore,
it is best to alternate chambers when filling with water so the unit
remains level. Check for leakage around the unit.
3.
See riser/conversion kit installation.
4.
Backfill with good quality granular soil around the unit that is free
of organic matter, rock, stone, tree roots, or other debris that could
damage the unit.
5.
Fill area around air port with gravel to prevent breakage due to
settling of unit (See figure 7).
6.
Tamp soil around perimeter of the unit as it is backfilled to stabilize
the unit and to reduce settling.
7.
Finalize backfill with a mounded contour so that surface water is
shed away from the unit. Under no circumstances should surface
water be allowed to accumulate around unit. Riser extensions are
available for deeper burial.
CAUTION
8.
MAXIMUM soil burial depth is 12" (305 mm).

COLD WEATHER INSTALLATION
When installing a Fusion
specify insulated lids and risers. In addition, the blower must be
protected from snow drifts by installing it inside a garage, home,
basement, crawlspace or riser. If installed in a riser, the blower must
be protected from inundation and must have a vent pipe installed to
above the maximum snow depth with a 180° angle at the end to prevent
snow and water entry. Also, the top and the sides of the Fusion
must be insulated with insulation sheeting or other means to provide a
minimum insulation value of R-8. Please contact the factory for further
information.
It is necessary to anchor the Fusion
prevent flotation. If groundwater rises above the rock or concrete pad
that the Fusion
sits on, anchoring is required. Please consult a design
®
engineer, soil scientist or other qualified individual to determine high
groundwater conditions.
1. Follow the procedures outlined in the Excavation and Installation
sections, items 1 - 5 to properly prepare and level the Fusion
excavation.
2. Follow the procedures outlined in the Backfilling section, items 1 - 2
to properly fill the Fusion
3. Refer to Figure 9, Anchoring Schematic to determine the minimum
amount of backfill to be placed around the Fusion
Tamp the fill to prevent settling.
4. Refer to Table 3, Concrete Anchoring Dimensions to determine the
amount of concrete needed for the concrete anchor collar that is
poured around the entire circumference of the Fusion
concrete to the specified dimensions to fully engage the mid-seam
of the Fusion
, which will anchor it once the concrete cures. Make
®
certain to pour the concrete in a manner to minimize trapped air
within the concrete. Agitating or lightly mixing the concrete with a
metal rod or other small device, once poured, will help release
trapped air.

5. Allow the concrete to harden before final backfilling.
