RESIDENTIAL & COMMERCIAL IRRIGATION |Built on Innovation®
Overview
Valve-in-Head
The Valve-in-Head design integrates
the control valve, solenoid, and manual
On-O-Auto detector within the rotor’s
heavy-duty, impact-resistant case.
The convenient and compact design is
appreciated by installers and end users.
Total-Top-Serviceability
With Total-Top-Serviceability, every
serviceable component can be accessed
from the surface without cutting into
the synthetic turf. The spacious ange
compartment can accommodate full-
sized waterproof splice connectors, and
the compartment can hold a decoder for
two-wire control system applications.
Key Benets
• Heavy-duty internal gear drive and
stainless steel pop-up riser provide
years of reliable operation
• Long-range performance exibility up
to 165' (48 m) with ve nozzles choices
• Full-circle and adjustable arc in one
model from 40° to 360°
• Adjustable speed of rotation using the
adjustment knob to set the speed to
your requirements
Important
The water may contain foreign objects
such as sand, rocks, and other impurities,
which can damage the rotor. To avoid
these problems, it may be necessary to
install a lter.
Aer Installation
Troubleshooting non-rotation aer
installation:
1. Check for plugged secondary nozzle.
2. Check for a blocked propeller in
turbine assembly.
Troubleshooting non-operation aer
connecting to a decoder system:
1. Check for proper wire connections.
2. Switch the two solenoid wires.

Hunter’s synthetic turf rotors are designed to cool, clean, and ush synthetic sports elds.
The ST-1700V long-range synthetic turf rotor oers high-performance irrigation from the eld
perimeter while integrating Valve-in-Head (VIH) capabilities and a Total-Top-Service (TTS) design
to simplify installation and maintenance. With the same heavy-duty internal gear drive as the
proven ST-1600-HS-B rotor, the ST-1700V provides years of reliable operation.
Caution
• Do not perform any adjustments or
controls during operation.
• Stand clear of the action area of the
rotor and the water jet.
• Ensure the water jet is not directed
toward persons, animals, power lines,
roads, or other objects.

Servicing and Maintenance
A. Replacing the cover and rotor
1. Remove the center plug with a at-
blade screwdriver and unscrew the
nut underneath. The lid will li o.
2. Use the gear drive insertion/removal
tool to unscrew the rotor from the
piston.
3. The tool will grab onto the screws
underneath the rotor.
E. Accessing the valve-in-head
Remove the rotor (see Step A). Remove
the boot. Unscrew the six Allen bolts on
the piston ange. Remove the piston.
1. Remove the snap ring with the
snap ring removal tool.
2. Remove the valve with the valve
insertion/removal tool.
B. Replacing the propeller
1. Remove the eight screws on the
turbine housing (six large, two
small). The propeller will pull out of
the housing.
C. Accessing the solenoid
1. Remove the three screws from the
top of the solenoid housing. The
housing lis o.
