SETTING INSTRUCTIONS
NOTE: The RPS 75I with Intelligent Flow Technology® is factory preset
with a 180° arc setting, and includes a pre-installed #2.5 nozzle.
SETTING THE ARC ADJUSTMENT
NOTE: The RPS 75I with Intelligent Flow Technology® has a fixed right
start and an adjustable left stop.
1. POSITIONING NOZZLE TURRET TO ITS “RIGHT START”
Place your fingers on the top center of the nozzle turret (I). Rotate the turret
counter-clockwise to the left stop to complete any interrupted rotation cycle.
Rotate the nozzle turret clockwise to the right start. This is the fixed side of
the arc. The nozzle turret must be held in this position for arc adjustments.
The right start does not change.
2. ADJUSTING THE RIGHT (FIXED) SIDE OF ARC
If the right side of the arc is not properly aligned, the sprinkler may spray
in areas not intended for watering such as driveways or adjacent properties.
The right side arc can easily be realigned.
OPTION 1: REPOSITION CAN ON THE FITTING
Turn the sprinkler can (K) and the fitting below it left or right to the desired
position. This may require temporary removal of the soil around the sprinkler
to allow you to grip the sprinkler can.
OPTION 2: REMOVE INTERNAL RISER ASSEMBLY AND REPOSITION
Unscrew the top (H) counter-clockwise and remove the internal riser assembly
(J) from the can. Once removed with nozzle turret (I) at its right start, reposition
the riser assembly so that nozzle arrow (O) points to the desired start position.
Replace the riser assembly back in the can and screw on the top. At this point
you have realigned the right arc stop, and you can adjust the left arc to an
appropriate setting.
3. ADJUSTING THE LEFT (VARIABLE) SIDE OF THE ARC
INCREASING THE ARC: Insert the (A) end of the Key into the arc set
adjustment slot (M). While holding the nozzle turret (I) at the right start, turn
the Key clockwise. Each full 360° turn of the Key will increase the arc 90°.
Adjust to any arc between 40° and 360°. The Key will stop turning, or there
will be ratcheting noise, when the maximum arc of 360° has been reached.
DECREASING THE ARC: Insert the (A) end of the Key into the arc set
adjustment slot (M). While holding the nozzle turret (I) at the right start, turn
Key counter-clockwise. Each full 360° turn of the Key will decrease the arc 90°.
Adjust to any arc between 40° and 360°. The Key will stop turning, or there
will be a ratcheting noise, when the minimum arc of 40° has been reached.
4. OPERATING THE DISTANCE/FLOW CONTROL
To reduce the distance of the flow stream, insert your key (A) into the
Distance/Flow slot (N) and turn counter-clockwise. NOTE: As the distance
is decreased the flow rate will also decrease proportionally. Turning the key
counter-clockwise to the stopping point will completely shut the head off at the
nozzle. To resume or increase distance and flow again, turn the key clockwise.

CHANGING A NOZZLE
1. REMOVING THE NOZZLE RETENTION SCREW
Use the hex (B) end of the Key to back out the nozzle retention screw (F)
so it clears the top of the nozzle. Turn counter-clockwise to remove or
clockwise to re-install or tighten down.
2. PULL UP THE RISER
Insert the (A) end of the Key in the keyhole (L) on the top of the nozzle
turret (I) and turn the key 1/4 turn to insure that the key does not slip out of
the keyhole when you pull it up. Firmly pull up the entire spring-loaded riser
to access the nozzle socket (G). Hold the riser assembly with one hand.
3. REMOVING THE NOZZLE
With nozzle retention screw removed or backed out, the nozzle (C) may
be removed by pulling outward on the nozzle fin (D) with a pair of needlenose pliers.
4. INSTALLING A NOZZLE
Press the desired nozzle (C) into the nozzle socket (G). Make sure the nozzle
fin (D) is on the right. Then re-install or screw in the nozzle retention screw (F).
SPRINKLER INSTALLATION
1. INSTALL AND BURY
Do not use pipe dope. Thread the sprinkler on the pipe.
Bury the sprinkler flush on the same watering zone.
2. INSPECTING THE FILTER
Unscrew the top (H) and lift the complete sprinkler assembly (J)
out of the can (K). The filter is located on the bottom of the sprinkler
assembly and can be easily pulled out, cleaned and re-installed.
3. WINTERIZATION TIPS
When using an air compressor to remove water from the system
please note the following:
a. Do not exceed 30 PSI.
b. Always introduce air into the system gradually to avoid air
pressure surges. Sudden release of compressed air into the
sprinkler can cause damage.
c. Each zone should run no longer than 1 minute on air.
Sprinklers turn 10 to 12 time faster on air than on water.
Over spinning rotors on air can cause damage to the
internal components.
