along with the pressure at the
Rain Gun, dictate flow rate and
radius of throw and should be
selected accordingly.
b. If you are using a part circle
Rain Gun, manually set the
desired rotation arc by pushing
the two friction collars to the
desired position (See Figure 3
of Installation Tips).
c. Flush pipeline delivery system
prior to installing Rain Gun.
d. If you are using the BSP or NPT
adapter, make sure that it is
securely bolted to the Rain Gun
using the 6 bolts and gasket
supplied. Make sure that the
adapter is securely tightened to
the 2" riser.
USER MANUAL
Rain Guns are high quality, high
performance sprinklers designed for a
variety of uses and applications where
relatively high flows and extended
radius of throw are desired. For best
results, please read the following
instructions before construction to
ensure optimal performance.
Start Up Note
Always verify pressure. Pressure at the
pump or point of connection does not
equal pressure at the sprinkler. The
most common problem associated
with sprinkler installations is
insufficient or too much pressure at
the sprinkler head. Your Rain Gun is
equipped with a pressure port to
accommodate a 1/4" NPT thread
pressure gauge, also included,
specifically for this critical system
pre-check.
Quick Start Guide
1. Configuring Your Rain Gun
a. A set of 6 nozzles and a spoon
adjustment bracket are
included to customize your
Rain Gun to your application.
The spoon bracket allows you
to set the rotation speed based
on the nozzle size and the
pressure at the gun. To ensure
a fast, problem free start up,
please refer to the spoon
bracket adjustment guide (Ref.
Table 2) to configure your Rain
Gun accordingly. The nozzles,

2. Installing Your Rain Gun
Now that you have configured your
Rain Gun, make sure that it is
mounted securely. If there is wobble
while your Rain Gun is in operation,
it is a signal that you are losing
energy needed to ensure optimal
rotation speed. Refer to Installation
Tips for more information if needed.
3. Starting Your Rain Gun
a. Make sure that the Rain Gun is
pointed in a safe direction and all
people in the area are ready.
b. Activate valve if automatic. If
controlled by a manual valve,
open valve slowly until the desired
pressure and flow are reached.
