retaining the needed movement. The first pivot at the inlet of the
swing joint is positioned vertically and provides the side-to-side
articulation. The remaining pivot points provide the up and down plus
forward and backward articulation. For future service considerations, it
is also desirable that the rotor and swing joint assembly can be raised
vertically out of the enclosure while still attached at the inlet. Test the
swing to confirm there is adequate movement to bring the swing joint
vertically up and out of the enclosure. Next, prime, glue and attach the
VA swing joint to the inlet piping.
noTE: The supply piping to the VA swing joint
must be 2" minimum from the control valve
through to the VA swing joint.

Installing the Quick Coupler and Inlet Piping

Run Quick coupler supply line to the appropriate location outlined
above. Connect 1" sch. 80 piping vertically and attach Quick
Coupler with appropriate fittings making sure the quick coupler's
upper surface is as close to the underside of the enclosure as
possible. Confirm location aligns with quick coupler access hole in
the enclosure's cover. Next, stake and band quick coupler and inlet
piping per specification.
noTE: Care needs to be taken to ensure the
rebar stake does not penetrate subsurface
piping or irrigation mainline.

Installing rotor rubber Cover Kit

First, remove the green logo cap on the rotor. It is much easier to
align and install the rubber cover kit to the rotor before the rotor
is attachment to the swing joint assembly. First, note the general
shape and orientation of the large circular rubber boot that must fit
over the rotor's flange (rotor's upper surface). Also note that there
are recessed areas on the underside of the boot that must align
with the ribs on the underside of the rotor's flange. It is easiest to
attach the boot at the narrowest section first. Hold the rotor so that
the rotor's flange compartment is facing away from you and you
can see ribs on the underside of the rotor's flange. Find the part on
the rubber boot where the hole in the boot is closest to the outer
edge. Attach this narrow section first while taking care to align the
rubber boot to the ribs under the rotor's flange. Continue attaching
the remaining sections. Once complete, confirm that all ribs on the
rotor are aligned with the recessed areas on the rubber boot.
noTE: Do not install the center logo cap from
the rubber cover kit at this time.

attaching rotor to the ST2008Va Swing Joint

Remove the red protective caps from the two Acme fittings that
are used to connect the rotor to the swing joint. First, thread the
90 degree elbow fitting into the gray swing joint outlet fitting
until it stops. Next, rotate the fitting counter-clockwise until the
elbow is vertical as shown. Now thread the Acme x Acme male
coupling fitting into the elbow fitting until it stops. Next, rotate the
coupling counter-clockwise ½ turn. Finally, thread the Rotor onto
the coupling until it stops. Then, rotate the rotor counter-clockwise
