Nozzle Removal and Replacement

I-60-36S:

STEP ONESTEP TWO

The nozzle is retained in the nozzle housing by a setscrew. To remove the nozzle, back out the setscrew so that the nozzle will clear.

Rotate the nozzle housing to place the diffuser yoke at its lowest position in order to provide clearance.

STEP THREE

Grasp a nozzle tab with pliers and pull to remove.

 

I-60-ADS: (to access nozzle housing)

STEP ONESTEP TWO

The nozzle is retained in the nozzle housing by a setscrew.

To remove the nozzle, first slide the diffuser pins to the extreme left, from the viewer's perspective, past the black stop post.

 

All Models: Place the replacement nozzle in the housing. Press firmly to fully seat the nozzle so that it clears the retaining setscrew. Run the setscrew down to retain the nozzle, taking care not to run it down so far as to interfere with the nozzle stream. For I-60-ADS models, ensure the diffuser pins are placed back in line with the nozzle after the new nozzle is installed.

Visually check for proper installation of nozzles and setscrews.

Arc Adjustment

 

All I-60-ADS adjustable arc sprinklers are preset at approximately 180º. Sprinklers may be adjusted with water on or off. It is recommended that initial adjustment be made before installation.

  1. Using the palm of your hand, rotate the nozzle turret counterclockwise to the left stop to complete any interrupted rotation cycle.
  2. Rotate the nozzle turret clockwise to the right stop. This is the fixed side of the arc. The nozzle turret must be held in this position for all arc adjustments.

To Increase Arc:

  1. Insert the key end of the Hunter wrench into the adjustment socket.
  2. While holding the nozzle turret at the right stop, turn the wrench clockwise. Each 360º turn of the wrench increases the arc 45º.
  3. Adjust to any arc between 40º–360º.
  4. Wrench will stop turning, or there will be a ratcheting noise, when the maximum arc (360º) is reached.

 

To Decrease Arc:

  1. Insert the key end of the Hunter wrench into the adjustment socket.
  2. While holding the nozzle turret at the right stop, turn the wrench counterclockwise. Each 360º turn of the wrench decreases the arc 45º.
  3. Adjust to any arc between 40º–360º.
  4. Wrench will stop turning, or there will be a ratcheting noise, when the minimum arc (40º) is reached.
