The 430R rotor is designed for residential and light commercial installations.
Nozzling Up The System
The 1.5 GPM nozzle comes pre-installed from the factory. A nozzle tree
consisting of five additional nozzles is provided with each rotor (
Please see the nozzle performance chart for flow rates. By using various
combinations of nozzle flow rates, you can balance the sprinklers to
achieve approximately the same precipitation rates.
Every case of 430R product contains two 430R rotor keys. The 430R key is
used to pull up the riser, to remove the nozzle, to reduce the radius and to
adjust the arc (
To Extract/Insert A Nozzle
Use the key to pull the riser up in order to access the nozzle orifice. Insert
the key into the pull-up hole (
Figure 3), turn it 90˚, and pull up. Hold the
riser in the pulled up position.
Using the end of the key, turn the radius adjustment screw counterclockwise
until it clears the top of the nozzle. See
Insert the key into the nozzle right side slot with the pointed end of the key
facing upwards. Use the point to extract the nozzle out. See
To install a nozzle, press the nozzle into the nozzle socket (
Turn the radius adjustment screw clockwise to its desired location ensuring
that it is in a position to hold the nozzle in place even if radius reduction is
not required (
To Set The Arc
The 430R rotor arc is factory pre-set at 40 degrees.
The 430R rotor has a fixed Right start. To find the right start position,
rotate the nozzle turret counter clockwise (to the left) until it stops, then
rotate the nozzle turret all the way back to the right.
To increase the arc, insert the key into the arc adjuster shown in
Hold the turret in place while turning the key counter clockwise. Keep
turning until the desired arc angle is reached.
As an example indicated in
Figure 7, the arc is set to 270˚. The sprinkler
will then water from the right start and rotate counter clockwise (see
8) until 270˚, the adjusted left stop, is reached. The sprinkler will then return
back to the right start and repeat the cycle.
To decrease the arc, insert the key into the arc adjuster. Hold the turret in
place while turning the tool clockwise.
To adjust the arc while the rotor is running, turn the turret gently in the
direction that it is spraying. Once the right start has been located, follow
the directions above to increase or decrease the arc.
To line up the right start with landscape features which define the right side
of the irrigated arc, simply turn the housing cannister and point the right
start towards the desired direction. You may also pull the riser up with the
key and rotate the LOWER portion of the riser until the right start is at the
DO NOT rotate the TOP portion of the riser.
CAUTION: The 430R rotor is designed for use in clean-water irrigation
systems only. Sprinkler component damage or malfunction can occur
if operated with any other water source.
The 430R rotor should be installed with
the cap at the finished grade. It is not
designed to be installed below grade.
The radius adjustment screw can be used
to reduce the radius throw by up to 25%.
You should note that this does not reduce
the flow of the nozzle.
The screen can be accessed through
the bottom of the riser. Remove the cap
of the 430R and lift the riser assembly
out of the housing cannister. If plugged,
the screen can be removed, cleaned,
and re-inserted into the riser.
