1. Excavate an area large enough for the Fusion

®

Series unit to be installed. See Figure 8 and Table 3 for the actual dimensions

of the unit. Excavation dimensions are calculated by adding 12-18" (305-457 mm) to the length and width of the Fusion

®

. This

will allow sufficient room for 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" (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 9).
5. Check unit to make certain it is level by placing a level at several locations on the riser. (riser covers removed) (Figure 9).

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. If necessary, install riser extensions on the adapter rings

prior to backfilling. See Table 1 for number and size of

access opennings. Riser extensions are available for

deeper burial. Make certain risers are sealed properly and

watertight.

4.

Apply two beads of silicone fully around

each riser section prior to securing with supplied screws.

5. Install riser covers.
6. 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.

7. Tamp soil around perimeter of the unit as it is backfilled to

stabilize the unit and to reduce settling.

8. 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.

9.

MAXIMUM soil burial depth over the unit

is 36 inches (914 mm).

COLD WEATHER INSTALLATION

When installing Fusion

®

in cold climates, the designer should

specify insulated lids and risers from the factory. These are

available as an option to the standard lids and risers. In addition,

the blower must be protected from snow drifts by installing it

either 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 degree angle at the end to prevent snow

and water entry. Also, the top and 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.

ANTI-FLOTATION PROCEDURES

It is necessary to anchor the Fusion

®

in high ground water

conditions to 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 Section items 1-5 to properly prepare and level

the Fusion excavation.

2. Follow the procedures outlined in the Backfilling Section

items 1-4 to properly fill the Fusion

®

with water and add

risers if needed.

3. Refer to Figure 10, Anchoring Schematic to determine

the minimum amount of backfill to be placed around the

Fusion

®

in the excavation. 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

®

. Pour 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 manor to minimize trapped air within

the concrete. Agitating or lightly mixing the concrete with

a metal rod or other similar device once poured will help

release trapped air.

5. Allow the concrete to harden before final backfilling.
6. Complete the procedures outlined in the Backfilling Section,

items 5-8.
