Installation Procedure
To assure maximum performance from your 690 Series Rotary
Sprinklers, read these instructions completely prior to installing or
servicing the sprinkler.
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. Flush lines thoroughly prior to installing sprinkler.
3. 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 sprinkler body threads.
