Figure 1). Please see the

nozzle performance chart for flow rates. By using various combinations of nozzle

flow rates and arcs, you can balance the sprinklers to achieve approximately the

same precipitation rates.

Every case of product contains two CR500 rotor keys (

Figure 1). The CR500 key

is used to pull up the riser, to remove the nozzle, to reduce the radius and to

adjust the arc (

Figure 2). Each use is described in the following instructions.

Figure 3), turn it 90º,

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 (

Figure 4a).

To remove the nozzle, insert the CR500 key into the slot at the top of the nozzle,

above the nozzle number. Exert pressure laterally while pulling on the key to

dislodge and remove the nozzle (

Figure 4b).

To install a nozzle, press the nozzle into the nozzle socket. The nozzle number

should be visible and the nozzle prongs should be at 12 o

’clock. Turn the radius

adjustment screw clockwise to its desired location (

Figure 5) ensuring that it is in

a position to hold the nozzle in place even if radius reduction is not required.

º.

To find the left stop position, rotate the

nozzle turret clockwise (to the right) until it stops, then rotate the nozzle turret all

the way back to the left.

To increase the arc, insert the CR500 key into the arc adjustment slot, indicated

by an arrow in the center of the turret. Hold the turret in place while turning the

tool clockwise. Keep turning until the arrow points to the desired arc. The arrow

will point to the adjustable right stop. See

Figure 6.

When the rotor is set at 360

º, it will continuously rotate in a clockwise direction.

To decrease the arc, insert the CR500 key into the arc adjustment slot. Hold the

turret in place while turning the tool counter clockwise. Keep turning until the arrow

points to the desired arc. The arrow will point to the adjustable right stop.

To adjust the arc while the rotor is running, turn the turret gently in the direction

that it is spraying. Once the left stop has been located, follow the directions above

to increase or decrease the arc.

To line up the left stop with hardscape features which define the left side of the

irrigated arc, simply turn the pop up housing or the shrub base and point the riser

slot where the sprinkler should start spraying. You may also pull the pop up riser

with the CR500 key and rotate the LOWER part of the riser until the slot is at the

desired left stop position.

DO NOT rotate the TOP part of the riser.

Figure 7). It is not designed to be installed below grade. The shrub version is

mounted above grade.

The radius adjustment screw can be used to reduce the radius of 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 pop up version and lift the riser assembly out of the housing can. The shrub

version can be unscrewed from the base. If plugged, the screen can be removed,

cleaned, and re-inserted into the riser.

The CR500 rotor has a universal stator which eliminates the need to regulate the

flow regardless of the nozzle used. There is a pre-installed check valve on the

CR500 rotor. Use of the check valve will eliminate low head drainage after the

zone has run.
