Construct Swing Joints
1.
Construct triple swing joints for each sprinkler as shown
in Figure  1. Use PVC  or ABS pipe  nipple for sprinkler
connection.
Note: On sites where the possibility of heavy equipment
rolling  over a  sprinkler exists,  the  swing joint  will flex
preventing damage to the lateral or main lines. On a new
installation in raw ground where the sprinklers are to be
initially installed  above the finished  grade and lowered
when  new  turf  is established,  the  swing  joint  allows
sprinkler repositioning without changing risers. This is a
common and  practical procedure  which eliminates the
problem  of dirt  being  accidentally  introduced into  the
lateral lines when a riser is changed.
2.
3.
Flush lines thoroughly prior to installing sprinkler.
Apply Teflon   tape  on riser threads.  Install sprinkler  to
riser and tighten.
CAUTION
Use only Teflon tape on riser threads. Use of pipe dope or other types of sealing compounds can
cause deterioration of plastic threads and components.
4.
5.
Install sprinkler on riser. Align part-circle heads by rotating sprinkler body on riser until radius adjustment slot on top of the nozzle
rubber cover is positioned to the left side of the intended coverage area.
Valve-In-head models  only:  Remove  tube retainer and cap  from sprinkler fitting.  Provide a service  loop in control  tube at
sprinkler to prevent binding. Slide tube retainer over end of control tube. Push control tube onto sprinkler fitting and secure with
tube retainer.

7.
Install sprinklers flush with grade to 1/2 in. (0–13mm) below grade.
