  • Page 10: Wiring

    5.5 Wiring The laid 2-core wire is installed for the electrical connection of the TS120 Impact Sprinkler. The wire is pulled through the right or left opening on the bottom of the housing into the solenoid compartment. Use one of the drain holes to pull the control wires into the sprinkler.
  • Page 11 In this installation, the electrical connection is not exposed to the soil, but is protected inside the sprinkler and readily top-accessible. This simplifies any search for faults and any maintenance work can be carried out at any time without digging.

  • Page 12: Start-Up And Operation

    6. Start-Up and Operation 6.1 Potential danger At start up, the impact sprinkler rises up out of the housing and builds up full pressure within about 5 seconds. The jet of water emitted can cause injury. For this reason, it is critical that all personnel and bystanders are clear of the irrigation area and are not in the path of the sprinkler’s nozzle opening.

  • Page 13: Start-Up

    6.2 Start-Up Procedure Be sure to follow the start-up procedure in order, a) to h). Steps a) Check electrical function: Before any water supply to the sprinkler is opened, activate the solenoid by means of the controller. An audible ‘clicking’ sound from the solenoid is indicative of its functioning properly. (The click is produced by movement of the plunger.) b) Ensure the manual control switch (located along the top cover of the rotor) is set to AUTO.

    6.3 Arc Setting • With this impact sprinkler the arc setting is infinitely adjustable between 30° and 330° and capable of a full circle 360°. • You can adjust the area to be watered by pulling or pressing on the relevant end of the top or bottom spring stop.

  • Page 15: Shut-Down And Preparing For Winter

    During times of possible frost, ensure there is no standing water in the sprinkler. • The TS120 Impact Sprinkler has an automatic drainage system. • The sprinkler has a discharge valve and will drain by gravity as long as water drains from the main pipe.
