Hunter ST Series, ST-1700-V Manual

Overview

Hunter's synthetic turf rotors are designed to cool, clean, and flush synthetic sports fields. The long-range ST-1700-V Synthetic Turf Rotor offers high-performance irrigation from the field 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 Synthetic Turf Rotor, the ST-1700-V provides years of reliable operation.

Valve-in-Head
The Valve-in-Head design integrates the control valve, solenoid, and manual On-Off-Auto selector 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 flange compartment can accommodate fullsized waterproof splice connectors, and the compartment can hold a decoder for two-wire control system applications.

Key Benefits

• Heavy-duty internal gear drive and stainless steel pop-up riser provide years of reliable operation
• Long-range performance flexibility up to 157' with five nozzle 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

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 filter.

After Installation
Troubleshooting non-rotation:

1. Check for a plugged secondary nozzle.
2. Check for a blocked propeller in the turbine assembly.

Troubleshooting non-operation after connecting to a decoder system:

1. Check for proper wire connections.
2. Switch the two solenoid wires.

• 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.

Replacement Parts

Servicing and Maintenance

1. Replacing the cover and rotor
   1. Remove the center plug with a flatblade screwdriver and unscrew the nut underneath. The lid will lift off.
      
   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.
      
2. Replacing the propeller
   1. Remove the eight screws on the turbine housing (six large, two small). The propeller will pull out of the housing.
      
3. Accessing the solenoid
   1. Remove the three screws from the top of the solenoid housing. The housing lifts off.
      
4. Part-circle and 360° operation
   
   1. Lift up the cover. Set the arc adjustment rings to the desired arc (this can be done by hand).
   2. Remove both adjustment rings completely to allow full 360° operation.
5. Accessing the valve-in-head
   Remove the rotor (see Step A) and boot. Unscrew the six Allen bolts on the piston flange. Remove the piston.
   1. Remove the snap ring with the Snap Ring Removal Tool.
      
   2. Remove the valve and stainless steel ring with the valve insertion/ removal tool.

1. Discharge port
2. Solenoid*
3. Water line to filter (RED)
4. Water line to Valve-in-Head (BLUE)

*If connecting to a two-wire system, there is potential for miswiring the solenoid. Should your solenoid not fire during system startup, your first troubleshooting measure should be to swap the two solenoid wires.
