For new tree or shrub installation, follow the steps below.
IMPORTANT: If the model includes a Hunter Swing Joint, simplify installation by threading the tee or elbow fitting onto the swing joint prior to attaching to the lateral line
After placing the tree or shrub in a prepared planting hole, space the RZWS units evenly around the root ball and flush with finished grade. Each tree or shrub should have a minimum of two RZWS units.
For RZWS models sold without internal hardware, add irrigation hardware as needed.
Attach each unit to the lateral line system.
Backfill the hole around RZWS units. In sandy soils, use a fabric filter sleeve to prevent soil infiltration. Hunter part number: RZWS SLEEVE.
Follow planting guidelines for specific tree species, and for local conditions.
