along with the pressure at th e

Rain Gun , dictate flow rate an d

radius of throw and should be

selected accord ingly.

b. If you are using a part circle

Rain Gun, m anu ally set thedesired rotation arc by pushing

the two friction collars to the

desired p osition (See Figure 3

ofIn sta lla tion Tips).

c. Flush p ipeline delivery system

prior to in stalling Rain Gun.

d. If you are using the BSP or NPT

adapter, m ake sure that it is

secure ly bolted to t he Rain Gun

using the 6 bolts and gasket

supp lied. Make sure that the

adapter is securely tightened to

the 2" riser.

USER MANUAL

Rain Gun s are h igh quality, high

performan ce sprinklers designed for a

variety of uses and ap plications where

relatively high flows and extende d

radius of throw are desired. For best

results, please read the following

instructions before construction to

ensure optimal perform ance.

Start Up Note

Always verify pressu re. Pressu re a t th epum p or point of connection does not

equal pressure a t the sprinkler. The

most comm on p roblem associated

with sprinkler installations is

insufficient or too mu ch pressure at

the sp rinkler head . Your Rain Gun is

equipped with a pressure port to

accomm odate a 1/4" NPT thread

pressure gauge, also included,

spe cifically for th is critical system

pre-check.

Quick Start Guide

1. Configuring Your Rain Guna. A set of 6 nozzles and a spoon

adjustmen t bracket are

included to custom ize your

Rain Gun to your ap plication.

The spoo n bra cket allows you

to set the rotation speed based

on th e nozzle size and the

pressure at the gun . To ensure

a fast, problem free start up,

please refer to the sp oon

bracket adjustm ent guide (Ref.

Table 2) to con figure you r Rain

Gun accordin gly. The no zzles,

2. Installing Your Rain Gun

Now that you have configured your

Rain Gun, m ake sure tha t it is

mo unted securely. If there is wobble

while your Rain Gun is in ope ration,

it is a signal tha t you are losingenergy needed to en sure optimal

rotat ion spee d. Refer toIn sta lla tion

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 a ll

people in the area are read y.

b. Activate valve if aut om atic. If

cont rolled by a m anu al valve,

ope n valve slowly un til the desired

pressure an d flow are reached.

Riser Installation

a. To ensure proper operation an d performance for the life of

your Rain Gun, the riser m ust be stab le and solidly installed to

resist vibration . An un sup port ed riser is insu fficient for prop er

oper ation. Addition ally, a PVC riser will not sup port t he

reaction load of a Rain Gun. Som e options that ma y be used

are: (Note: confirm friction loss an d flow in your app lication)

Option 1: Galvanized riser strapped to a 6" x 6" pressure

treate d wood p ost (See Figure 4).

Option 2: Galvanized riser set in a p illar of concrete

(See Figure 5).

Option 3: A portable gun stand designed to support a Rain

Gun. (Contact your dealer for a recomm ended supp lier.)

b. Install Rain Gun t o riser as shown in Figure 6

or 7.

c. Inclined operation: The preferred installation on an inclined plane

is on a vertical riser regardless of angle of

incline.

If the riser must be set at an angle, use the rear

coun terweight (part nu m ber L00270) for

pro per ro tation o f your Rain Gun. The weight is

designed to help th e Rain Gun rotate up hill.

If you are using a portable gun stand, please

consult the m anu facturer to be sure it is

designed to supp ort inclined terrain.

d. For more h elp with your installation, please call

your Rain Bird Dea ler or District Mana ger. The

toll free Rain Bird n um ber is listed on the b ack

page of this guide.

Traveler Installation

a. Make sure that the p ressure at the gun is over

45 psi. Most users und erestimate the pressure loss

in the pipe, which is very high. Adjust your sp oon

bracket in relation to the n ozzle size and th e

pressure at the gun.

b. On sloped terrain, weight compen sation may be

required for proper rotation. For such cond itions,

a rear cou nterweight is available (Part nu mb er

L00270, sold separately).

c. As an alternative to u sing a counterweight, some

travelers can be vertically adjuste d.

Center Pivot Installation

a. For proper opera tion, make sure that the pressure

at the gun is over 45psi. Many users underestima te

the p ressur e loss in th e pivot, which is very high,

especially at the e nd -gun location . Adjust your

spoon bracket in relation to the n ozzle size and

the pressure at the gun (Refer to spoon bracket

adjustmen t guide, Table 2).

b. Make sure that the pivot end-gun mou nting

position is stable.

Should you experience op erating

difficulties, here a re som e tips that

ma y apply to your app lication. For

further assistance, please record th e

date code, the serial num ber on the

elbow, and th e pressure at the gun,

an d call your Rain Bird Dealer or the

toll free Rain Bird n um ber listed at th e

back of this guide.

Rain Gun does not rotate

or rotation speed is too slow Install a 1/4" pressure gauge into

the Rain Gun pressure po rt and

verify adequate op erating pressure.

Refer to Spoo n Bracket Adjustm ent

guide (table 2) for pr oper

configuration of spoon bracket

base d on nozzle size. Also check

the spoon and the arm for damage.

If pressure is below specification

and the Rain Gun is prop erly

configured, decrease th e n ozzle

size to increase pressure at the gun.

If pressure is lower than it was at

installation, check for obstructionsin the wat er line. You m ay be able

to flush ob structions from the

sprinkler an d water line by

rem oving the nozzle and turn ing

on the water.

If pressure is still low after

rem oving obstructions, and your

Rain Gun still does not r otate, you

may need to add a booster pump or

increase pressure in anoth er way.

Rotation speed too fastInstall a pressu re gauge at th e Rain

Gun pressure po rt and refer to Spoon

Bracket Adjustm en t guide (tab le 2) for

proper configuration of spoon b racket

to n ozzle size. Also check th e spo on

for damage. For proper op eration, the

operating pressure at the gun sh ould

not exceed 100 psi.

Rotation speed varies fromone direction to another Check that the spoon is properly

installed on the arm .

Check that the arm is not bent .

Check that the nozzle is properly

installed in th e n ozzle h ousing.

It should be seated squarely.

Check the condition of the spoon.

If broken , it will need t o be

replaced.

Gun does not reverse Install a pressure gauge at the Rain

Gun pressure port an d refer to

Spoon Bracket Adjustm ent guide

(Table 2) for prop er con figuration

of spoon b racket to nozzle size.

Pressure at gun shou ld not exceed

100 psi.

Check trip mechanism by manually

operating it. Operation shou ld be

free and sm ooth.

Check trip m echanism spring. It

mu st have tension and be prop erly

installed.

Check bushings at the trip

mech anism. They mu st be clean

and not damaged.

Arm stroke frequency is

too high Make sure pressure is not above

100 psi.

Make sure the front arm

coun terweight is insta lled

(below sp oon).

Make sure the rear arm

coun terweight is installed.

Gun rotation slows downover time Refer to first troubleshooting tip

above for non-rota ting or slow

rotation.

Trip stop mechanism is not

holding the gun at thedesired arc Make sure that the trip stops are

not loose by push ing against them

with your finger. (See Figure 3)

Turn your gun m anually to the tripstops. They should hold when th e

trip lever pushes against them .

If your Rain Gun has recently been

re-assembled, make sure that the

trip lever was not re installed in

between the trip sto ps. This will

open the trip m echanism an d not

stop the Rain Gun.

Arm does not move Check the pressure at the gun

Check that the nozzle is properly

installed on th e nozzle housing

Make sure that the nozzle retaineris tightene d

Check that the spoon is not broken

Check that the mechanical stop

(arm stop) on the arm is not

damaged

Check that the arm is not bent
