FIBERGLASS “OUTDOOR” APPLICATION
1. Inspect your basin assembly. If the unit has been damaged
in shipment or if parts are missing, contact your distributor before
installing.
2. Carefully read all literature to familiarize yourself with details
regarding installation and use. Retain materials for future reference.
3. All installations must comply with all applicable electrical and
plumbing codes, including but not limited to the National Electrical
Code, local, regional and/or state plumbing codes, etc.
4. Dig a hole for the basin. The hole should be at least 24” larger in
diameter than the basin diameter to provide 12” of backll all around
and deep enough to provide either 12” of compacted backll or 6”
when a concrete pad is required. Ensure the removable cover
extends above the nished grade line and the grade slopes away
from the unit. Backll and subbase should be 1/8” –3/4” pea gravel
or 1/8” –1/2” crushed stone.
5. Note: Care must be taken when excavating in order to avoid
underground utilities and disturbance of existing structure
foundations. The hole should be located at least ten feet
from adjacent structures. Additional distance may be re-
quired to sufciently locate the basin outside of the loading
area of the adjacent structures.
6. Determine the location of the inlet based upon your inlet pipe arrange-
ment. The inlet must be used with 4” pipe. It should be installed on
the side of the basin opposite the oat switches. To install a 4” cast
iron inlet hub, use a 4” holesaw to drill into the side of the basin at
the correct elevation. Center the hub inner diameter with the hole in
the basin. Attach the hub to the side of the basin using the sealant
and hardware provided. To install a pipe seal, use a 5” holesaw to
drill into the side of the basin at the correct elevation. Insert the pipe
seal from the outside of the basin.
7. The bottom of the excavation can now be back lled and compacted.
Set the basin in the hole and connect the 4” inlet pipe. If using a cast
iron hub, seal the pipe to the ange with approved caulk or gasket.
If using a pipe seal, use liquid soap as a lubricant if necessary.
8. The cover bolts should be installed into their threaded inserts to
prevent damage to the threads during the nal stages of installation.
9. Pouring a concrete anchor around system can now be completed.
Basin should be lled with water when pouring concrete to minimize
movement of the system. Backll around basin with specied media.
Care should be used to avoid damaging components or leaving voids
when back lling.
10. Note: Venting can be installed on basin cover as necessary
according to all applicable national, state, and local plumb-
ing codes.
11. Clean any debris out of the basin.
