enclosure cover installed. Sleeves are to be notched on two sides to
allow sleeves to go over piping.
Route and position controller cables into underside of the
control-valve sleeve and install the valve sleeve. Next position and
install the ball-valve sleeve.
With the rotor held within the enclosure's cover, check to see if the
swing joint needs adjustments in order to achieve a rotor grade
that is level to the enclosure cover. If so, remove/add gravel as
necessary to achieve desired grade. Continue back-filling and
packing the material. Finished level of the back-fill is to be at the
same level as the bottom of the rotor's compartment (approx. 5"
from the underside of the enclosure's cover. Check to see if the
rotor will remain in position if released. If not, pack more back-fill
material beneath the rotor.
Next, carefully lift and remove the cover from around the rotor. Now
stake and band the rotor per specifications taking care not to move
rotor's position. Once complete, replace cover to confirm that rotor
remains to grade. If not, adjust.
noTE: Care needs to be taken to ensure the
rebar stake does not penetrate subsurface
piping or irrigation mainline.
Cable Connections
Make wire splices connections per specifications using approved
wire splice connectors.

Setting rotor's arc orientation and arc adjustment

In order to position the rotor such that it will apply water in the intended
area, the arc orientation (direction) and the adjustable arc must be set.
These initial adjustments can be made without water running through
the rotor. The first step is to remove the riser assembly so that the right
fixed stop of the arc adjustment mechanism can be aligned to the right
side of the area to be irrigated. In order to remove the riser assembly,
the upper snap ring must be removed from the rotor.
Upper Snap-Ring Removal
Prior to removal of the upper snap-ring assembly, the rubberized logo
cap must be removed and the riser assembly must be pressed below
the snap-ring's rubberized seal. If the procedure below is not followed,
the upper snap-ring assembly cannot be removed from the rotor.
Remove the stainless screw from the center of the rubberized
logo cap using a Phillips screwdriver (fig 1). Prior to removing the
rubberized logo cap, note that the arrows on the logo indicate the
position of the nozzles on the riser assembly. As the rubberized logo
cap is removed, note there is a protruding pin on the underside of the
logo cap (fig 2). This pin is the alignment feature on the rubberized
logo cap that must be inserted correctly during assembly in order for
the arrows on the rubberized logo cap to be positioned over the nozzles
below. Note which hole the pin fits into on top of the riser (fig 3).
