Institutional Series™ Gear-Driven Sprinklers
I-90 ADV & 36V Nozzle Installation
Caution! The riser assembly is under spring tension. Eye protection
should be worn and proper procedures followed when servicing
this product.
Tools needed: Phillips-head screwdriver, needle-nose pliers.
Preparation
Unscrew the body cap from the body, then withdraw the riser from
the body. Compress riser spring and seal assembly by pressing
downward to expose nozzles. Hold compressed assembly in this
position rmly with one hand while servicing with the other hand.
Nozzle Removal and Replacement
Remove the logo cap, which is retained by a central Phillips screw.
The nozzle is retained in the nozzle housing by a setscrew. To remove
the nozzle, back out the setscrew using the hex key on the Hunter
wrench so that the nozzle will clear. Grasp the nozzle with pliers and
pull to remove.
Insert the replacement nozzle in the housing. Press rmly to fully seat
the nozzle so that it will clear the retaining setscrew. Using the hex key
on the Hunter wrench, turn the setscrew down to retain the nozzle.
Note: When changing from one nozzle number to another, check the
stator for proper setting before returning the head to service.
Stator Ring Adjustment
Note: When installing nozzles you must also correctly set the stator to
ensure proper speed of rotation. Failure to correctly set the stator may
cause a non-rotation condition.
The stator is located in the base of the riser assembly. First remove
the riser assembly from the body. Then remove the lter screen to
access the stator.
The stator has a protruding tab that aligns with a pointer. Remove the
stator by grasping this tab with pliers and pulling. Replace the stator so
that its pointer is set to the number agreeing with the nozzle installed.
Refer to the Nozzle / Stator Chart below for nozzle and stator settings.
Visually check for proper assembly of nozzles, setscrews and stator.
Reverse the preparation procedure to reassemble the unit.
Precipitation Rate Adjustment
If you have excessively wet or dry areas, you can change the nozzle in
the sprinkler to increase or decrease the precipitation rate. For dry areas,
install a larger nozzle. For wet areas, install a smaller nozzle.
I-90 ADV Only – Arc Adjustment
Adjustable heads are preset to approximately 180°. Sprinklers may be
adjusted with water on or off. It is recommended that initial adjustment be
made before installation.
Rotate the nozzle turret clockwise to the right stop. This is the xed side of
the arc. The nozzle turret must be held in this position for arc adjustments.
The right stop does not change.
To Increase Arc:
1.
Insert the plastic key end of the Hunter wrench into the adjustment
socket (Fig. 1 & 2).
2. While holding the nozzle turret at the right stop, turn the wrench
clockwise. Each full 360° turn of the wrench increases the arc 45°.
3. Adjust to any arc between 40° and 360°. The wrench will stop turning,
or there will be a ratcheting noise, when the maximum arc of 360°
(full circle) has been reached.
To Decrease Arc:
1. Insert the key end of the Hunter wrench into the adjustment socket
(Fig. 1 & 2).
2.
While holding the nozzle turret at the right stop, turn the wrench
counterclockwise. Each full 360° turn of the wrench will decrease the arc 45°.
3. Adjust to any arc between 40° and 360°. The wrench will stop turning,
or there will be a ratcheting noise, when the minimum arc of 40°
has been reached.
Note: It is not necessary to disassemble the sprinkler to make adjustments.

I-90 ADV Only – Aligning the Right (Fixed) Side of the Arc
If the right side of the arc is not properly aligned, the result may be a wet walkway or a dry turf area. The right
side can easily be realigned. One way to realign the right stop is to unscrew the body cap counterclockwise
and remove the internal assembly from the body. Once removed, rotate the nozzle turret to the right stop, insert
the internal assembly back into the body with the nozzle aligned to the right side of the area you want irrigated.
At this point you realigned the right arc stop, and you can adjust the left arc to an appropriate setting.
