Example (see shaded area):
You have 60 PSI and a 14 mm nozzle; the chart
recommends configuration A or B. This means that your
Rain Gun
®
will operate properly in either configuration,
but the rotation speed will be faster in A than in B.
SR3003 / F3002 Configuration Details
Nozzle Selection
Select one of the six nozzles
provided based on your
performance requirements,
available water pressure
(at the Rain Gun), and flow
capacity. Refer to Table 1
and Figure 1.
Spoon Adjustment
Bracket
Install the Spoon
Adjustment Bracket, if
needed, in accordance with
Table 2. Refer to Figures A,
B, and C.
Rotation Angle Adjustment
For part circle (SR3003) model only, adjust desired rotation angle manually as shown.

Figure A: Bracket not installed
Provides maximum drive and
rotation speed at low pressures.

Figure B: Plus position (+)
Provides an intermediate
position to regulate rotation
speed at intermediate pressures.
Figure C: Minus position (–)
Provides greatest slowing of
rotation speed at high pressures.
