CHAPTER
                                   INSTALLATION
       3
SPELFilter systems are installed along with the storm drain. Installation procedures vary depending on the
configuration of the SPELFilter system. Installation instructions for manhole SPELFilter systems and precast vault
SPELFilter systems are contained in this section.

Custom SPELFilter systems may have particular installation issues that will be addressed during the design.
Installation instruction for a custom SPELFilter will be included with the custom design documents.


INSTALLATION OF A SPELFILTER SYSTEM
1. Contact utility locator to mark any nearby underground utilities and make sure it is safe to excavate.
2. Reference the site plan and stake out the location of the SPELFilter manhole/vault.
3. Excavate the hole, providing any sheeting and shoring necessary to comply with all federal, state and local
    safety regulations.
4. Level the subgrade to the proper elevation. Verify the elevation against the manhole/vault dimensions, the invert
    elevations, and the site plans. Adjust the base aggregate, if necessary.
5. Have the soil bearing capacity verified by a licensed engineer for the required load bearing capacity. On solid
    subgrade, set the first section of the SPELFilter manhole/vault.
6. Check the level and elevation of the first section to ensure it is correct before adding any riser sections.
7. If additional section(s) are required, add a watertight seal to the first section of the SPELFilter manhole/vault. Set
    additional section(s) of the manhole/vault, adding a watertight seal to each joint.
8. Install the trolley system (if applicable). See separate instruction sheet.
9. Install the PVC outlet manifold. Glue all PVC joints with the exception of the SPELFilter cartridge coupling.
10. Install the PVC outlet pipe in SPELFilter manhole/vault.
11. Install the inlet pipe to the SPELFilter manhole/vault.
12. After the site is stabilized, remove any accumulated sediment or debris from the vault and install the SPELFilter
    cartridges.

Tool List:

t   PVC glue and primer
t   Crane / lifting mechanism to lower cartridges in to the vault (each cartridge weighs 350 lb)
t   Screwdriver or nut driver for Fernco couplers
t   Soft blow hammer
t   Saw (in case PVC manifold length needs to be adjusted)
