Sprinkler Spacing Guidelines
• Square Spacing
No wind - 55% of diameter
4 mph wind - 50% of diameter
8 mph wind - 45% of diameter
• Triangular Spacing
No wind - 60% of diameter
4 mph wind - 55% of diameter
8 mph wind - 50% of diameter
• Single-Row Spacing
No wind - 50% of diameter
4 mph wind - 50% of diameter
8 mph wind - 45% of diameter
Note:
Designing for zero (0) mph
wind conditions is not recommended.
Design for worst wind conditions.

Toro Technical Data Manual,
form number 490-1737.
Toro Swing Joints
Use Toro swing joints to connect the sprinklers to the lateral/main line pipe.
Toro swing joints provide swivel joints that allow the sprinkler body to be easily positioned
to finished grade and prevents pipe breakage by providing the flexibility to allow downward
movement if the sprinkler is run over by heavy equipment.
For installation using pipe thread connections (NPT or BSP), use PTFE tape only to seal
all threaded connections.
CAUTION: Use PTFE tape only for sealing pipe thread connections. Use of pipe dope or
other paste sealants can cause deterioration of the sprinkler body threads.
Tape should be applied to the male threaded fitting in compliance with the tape manufacturer
recommendations. Thread the fitting into the mating female threaded fitting in the sprinkler
body and service tee and tighten securely.
For installation using ACME thread connections, do not apply additional sealant.
CAUTION: ACME fittings incorporate an o-ring seal that requires no additional sealant.
Sprinkler fitting installation - Thread the ACME fitting into the sprinkler body and hand tighten until it stops. No
additional tightening or loosening is required.
CAUTION: Loosening beyond 270
°
will result in a thread leak.
Lateral/Mainline pipe installation - Thread the ACME fitting into the lateral/main line service tee and hand tighten until
it stops, then loosen up to one full turn to ensure flexible movement of the swing joint.
Wire Splices
CAUTION: Communication cable or station wire connections will deteriorate when exposed to moisture and earth
ground causing shorts or open circuits resulting in improper system operation.
All direct burial wire connections must be done with approved waterproof connections installed in compliance with the
manufacturer specifications. Contact your Toro Golf Distributor for approved waterproof connectors.
Always provide a wire service loop for each splice to ensure sufficient wire is available should future servicing be
required.
