1. Bioguard Root Control Fabric: To prevent plant roots clogging the inlet holes, leading to premature failure of system. Bioguard is EPA-registered root control fabric coated with Trifluralin, a herbicide that prevents root cell division. Biobarrier cut into 3" squares by Planter Technology, Inc.
   
2. Drainage Overflow Adapter: Overflow adapter to be sealed over drain hole of planter. Requires container to be sealed. Typically 5"h, to allow container to catch all irrigation run-off, but allow rain water to escape. Installed in field by contractor.
   
3. Changeable Parts: Sealing cap, one sided grommet, sensor tube. All parts shall initially included with CWM units and shall be removable and replacable.
   
4. 3/4" ID Braided PVC tubing for connecting units.
   
5. Quick-Snap hose clamps for PVC connections. Prevents corrosion of clamps, ease of change.
   
6. Plastic elbow fittings for square and rectangular containers. Prevents kinking of hose.
   

1. Prior to order, the contractor shall verify size, location and quantity of CWM units required. 1
   

1. Refer closely to manufacturer's planting instructions.
   
2. Install Drainage Overflow Adapter (when used) prior to installing CWM units.
   
3. Trim fill tube to rise up approx. 1" higher than the level of the soil. Angle fill tube when possible. Tube requires some assembly.
   
4. Install level to permit correct functioning. Allow access to water inlet.

1. Field verification of plant size, and fit into decorative containers is frequently overlooked by the contractor, and can lead to delays and additional cost if neglected.
