Sprinkler Installation

3.
Construct or install manufactured triple swing joints for each sprinkler. See Figure 2.
Flush lines thoroughly prior to installing sprinkler.
Apply PTFE pipe thread tape to the sprinkler nipple threads. Install the sprinkler to the
nipple, tightening by hand to a snug fit.
CAUTION: Use only PTFE tape on plastic thread connections. Applying pipe dope
or other thread-sealing compounds can cause deterioration of plastic threads.
Arc Adjustment
The TS90 series sprinkler features both an adjustable arc from 40° to 330°, in 5° increments,
and full-circle 360° operation. All TS90 series sprinklers are preset to half-circle (180°) arc
when shipped from the factory.
Figure 3
The left side of the adjustable arc is fixed, and is aligned to the left watering border by
turning the ratcheting riser assembly in the sprinkler body. The right side of the arc is aligned
to the right watering border by turning the nozzle turret while compressing and holding the
adjustment band in a stationary position.

Arc adjustment can be made wet or dry. For dry adjustment, insert the blade of the
sprinkler tool (included in carton) through the slitted opening in the top of the nozzle turret.
Twist the tool 1/2 turn to catch the inside of the nozzle turret, then pull the riser assembly
out of the body until fully extended. Grasp the riser below the gray adjustment band and
hold firmly to prevent retraction. See Figure 3.
Figure 4
Note: Specific arc settings of 90°, 180°, 270° and 360° are provided on the adjustment
band to preset the sprinkler arc if desired. To use this adjustment option, simply compress
the serrated portion of the adjustment band and turn it to align the preferred arc indicator
with the nozzle turret arrow indicator. See Figure 4.

Find the sprinkler left and right arc limits by rotating the nozzle turret back and forth (in the
direction of free travel only). The left stop indicates the fixed (non-adjustable) side of the
arc. See Figure 5.
270°
360°
CAUTION: Do not force the nozzle turret past the arc travel limits. Permanent
damage to the drive assembly can result.
With the nozzle turret rotated to the left stop, align the nozzles to the left watering border
by ratcheting the riser assembly in either direction. See Figure 6.

Find the sprinkler right stop by rotating the turret clockwise until it stops.
To adjust the arc, compress the ribbed area of the adjustment band, then rotate the nozzle
turret to align the nozzles with the right watering border. For full-circle operation, rotate the
nozzle turret to the right until it stops. See Figure 7.

With the sprinkler on, check arc setting again and fine tune arc setting as needed.
Main Nozzle Trajectory Adjustment
Figure 6
The main nozzle trajectory angle is factory-set at 25°, and is adjusted between 7°—30°
by turning the trajectory adjustment nut, accessible through the top of the nozzle turret.
Typical uses of this feature are to increase trajectory to compensate for high-mounded turf,
or to decrease trajectory to clear low-hanging tree branches.
Note: Prior to changing the nozzle trajectory, it is important to consider that increasing the
trajectory increases the spray radius, and decreasing trajectory decreases the spray radius.

nut clockwise to decrease trajectory or
counterclockwise to increase trajectory,
as indicated by the bidirectional arrow.
See Figure 8.
