RZWS SERIES
ROOT ZONE WATERING SYSTEM
INSTALLATION INSTRUCTIONS
For New Tree or Shrub Installation
INSTALLATION STEPS
1. 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 (Fig. 1).
2. 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 (Fig. 2).
3. For RZWS models sold without
internal hardware, add irrigation
hardware as needed.
4. Attach each unit to the lateral
line system.
5. Backfill the hole around RZWS units.
In sandy soils, use a fabric filter sleeve
to prevent soil infiltration. Hunter part
number: RZWS SLEEVE.
6. Follow planting guidelines for specific
tree species, and for local conditions.

For Existing Tree Installation
INSTALLATION STEPS
1.
Dig holes to desired diameter and
depth. Each hole should be a minimum
of 5 inches in diameter and the required
depth to allow the RZWS unit to be
installed flush with finished grade.
RZWS units may be cut to depths
not specifically offered.
2. Place units evenly spaced around
the tree, located at half the distance
between the trunk and the edge of
the tree canopy (Fig. 3). The required
RZWS units will vary with tree watering
requirements. Each tree should have a
minimum of two RZWS units.
3. For RZWS models sold without
internal hardware, add irrigation
hardware as needed.
4. Attach each unit to the lateral
line system.
5. Backfill the hole around RZWS units.
In sandy soils, use a fabric filter sleeve
to prevent soil infiltration. Hunter part
number: RZWS SLEEVE.
6. Follow planting guidelines for specific
tree species, and for local conditions.
Note: To service the RZWS, use a tool
to access and release the two snaps
from the cap (Fig. 4).
