Series  Stream  Rotor Sprinkler
Installation  Instructions
Introduction
The Toro 340  Stream  Rotor sprinkler  series  is designed  to deliver  maximum watering  efficiency  and  adjust-
ment simplicity.  The gentle  carrousel  spray applies  water  slowly for  minimal run  off making  it ideal  for newly
seeded  lawns and  planted slopes  as well  as established  landscape  areas.
Each 340  sprinkler  is supplied  with a plastic  arc disk
Figure 1 – Arc Disk Tree
tree providing  nine  matched-precipitation  rate  arc
disks. The  arc disks,  as shown  in Figure  1, range
from 90°  to 360°,  enabling the  340 sprinkler  to adapt
perfectly  to virtually  any landscape  design.  You may
use any  of the Stream  Rotor  nozzles.
Each of  the 340  sprinkler models  has their  own
unique  qualities as  well. The  Lawn sprinkler  pops up
a full  4" (10cm)  to clear tall-cut  grass  and features  a
built-in  check valve,  effective for  up to 8'  (2.4m) of
elevation  difference,  preventing  seepage from  lower elevation  sprinklers.  The  shrub sprinkler  has a  versatile,
stepped-thread  inlet  base enabling  either  1/2" or 3/4"  NTP riser  pipe to be  used for  installation.  The High-Pop
model  extends nearly  12" (31cm)  to easily  clear shrubs  and tall  ground  cover. Provided  with side  and bottom
3/4"
NTP inlets,  the High  Pop installs  easily  without deep  trenching.
Planning Your Installation

Proper  application  and placement  of the  340 sprin-
klers is  essential  for optimum  water distribution.
The illustration  in  Figure 2 shows  a basic  sprinkler
layout  which provides  the required  head-to-head
coverage.  Quarter  circle (90°)  spray patterns  are
used in  each corner,  half circle  (180°) arcs  are
equally  spaced on  the perimeter  and full  circles

the sprinklers  are  placed to  enable the  spray of
each sprinkler  to  reach all neighboring  sprinklers.
Sprinkler Installation Methods
When installing  the  340 sprinkler,  Toro Funny Pipe
and fittings  are recommended   for ease of  installa-
tion, accurate  sprinkler  positioning  and lateral  line
protection.  The flexible  Funny  Pipe link helps  pro-

tect the  lateral pipe  and fittings  from damage  due  to
a forced  downward  or lateral  movement.  Figure 3
illustrates  how easily  Funny Pipe  can connect  the
various  340 sprinkler  models.  This is extremely
helpful  when replacing  sprinklers  of different  height
or inlet  position. Installing  the  sprinklers  on a tradi-
tional swing  joint  is also an  acceptable  installation
method.  Rigid pipe  risers are  not recommended  due
to the  potential for  lateral line  damage.
