The SMART ACCESS feature adds several significant capabilities that allow maintenance crews to access most internal
components without having to dig or turn off the water.
Prior to installing the sprinkler, please read this Installation and Service Guide for proper installation and servicing procedures.
Observe all Warnings and Cautions when installing and operating this equipment.
Product Features
• Top accessibility of the pilot valve, GDC intelligence
module, wire splices, and all future enhancements. No
excavation required to access any internal components.
• Pilot valve is removeable while system is under pressure.
• Compartments provide space for current features and
future enhancements.
• Similar physical dimensions as Toro’s original sprinkler
bodies for easy replacement.
• Removeable marker is customizable for yardage markers,
station number, golf course branding, and/or other
customer desired information.
Installation
Toro Swing Joints
Toro recommends using Toro Swing Joints for INFINITY Series sprinklers.
• On sites where the possibility of heavy equipment rolling over the
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 the turf
is established, the swing joint allows sprinkler repositioning without
changing risers.
Note the correct and incorrect
swing-joint installation method.

ACME Thread Notes
The ACME thread golf sprinkler body requires an ACME thread swing joint for connection to the piping system. The ACME
swing joint has an o-ring on the exit fitting that provides a water-tight seal inside the sprinkler body when properly assembled.
!
CAUTION: With the ACME fitting, do not use thread sealants such as
Teflon™ tape or pipe dope.
! Important! For ease of assembly and to ensure proper sealing, moisten the
o-ring with clean water just prior to installation.
To Install Sprinklers:
Screw the sprinkler body clockwise onto the ACME swing joint exit fitting until
it stops. No further adjustment is required.
! CAUTION: Leakage between the swing joint exit fitting and the
sprinkler body may indicate that the o-ring is improperly seated, missing,
damaged and/or the sprinkler body is not completely installed.
If leakage is observed, perform the following procedure:
1. Shut off and relieve system water pressure.
2. Remove the sprinkler from the swing joint fitting.
3. Verify that the o-ring is undamaged and is properly seated in the o-ring
groove. (Replace the o-ring if necessary.)
Moisten the o-ring with water, reinstall the sprinkler, repressurize the system
and check for leakage.

Sprinkler Wiring Connections
Connecting Communication Cable to the INFINITY Series with GDC Module
The GDC system provides a coded DC signal over a polarity sensitive color coded communication cable that requires correct
connections to ensure proper operation. The GDC system also employs a daisy chain communication network where all
sprinklers, except the last one on a wire run, will have one cable coming in from the Gateway or closer sprinkler and another
going out to the next sprinkler.
1. If using jacketed cable, remove ~20” (508
mm) of shielding from communication
cable(s).
2. Route wires through the access grommet in
the bottom of the sprinkler compartment.
Provide a service loop below the sprinkler
to allow for height adjustment and future
servicing. (See Figure 1.)
Figure 1
Figure 2

grommet
3. Pull cable(s) out the top of the sprinkler
approximately 6˝ (152 mm). (See Figure 2.)
4. Strip 12-16 gauge wires 7/16˝ (11 mm) of
insulation. (See Figure 2.)
5. Connect the white cable wire(s) and the white
GDC module wire with a wire nut and install
into a waterproof grease cap (both provided).
(See Figure 3.)

6. Repeat for the black wire(s). (See Figure 3.)
7. Fold and tuck the cable connections into the
compartment pocket.
8. Record GDC module address and reference to
site location. Remove the 2 additional address
labels from the accessory kit. Affix one to the
cover for temporary future reference and the
other to the location identification form for
entry at the central controller.
9. Replace cover and install the three (3) cover
screws (from accessory kit). Tighten to 25
in/lb. (34,6 kilogram force meters) max or
medium torque and low speed setting on a
battery-powered screw-driver.

Connecting Control Wires to the INFINITY Series with Satellite
The field satellite controllers provide a 24 VAC
signal to the sprinklers typically using individual
wires. Connections to the sprinkler solenoid in
these systems are not polarity sensitive and do
not require specific wire connections. Typically
the “common” wire from the controller is daisychained to multiple sprinklers with one wire
coming in from the satellite or closer sprinkler
and the other going on to the next sprinkler. The
station output “hot” wire typically connects to a
single sprinkler but can also be daisy-chained to
multiple sprinklers depending upon the control
system capabilities.
1. Route all wire(s) through the access grommet
in the bottom of the sprinkler compartment
providing a service loop below the sprinkler
to allow for height adjustment and future
servicing. (See Figure 1.)
2. Pull all wire(s) out the top of the sprinkler
approximately 6˝ (152 mm). (See Figure 2.)
3. Remove 7/16˝ (11 mm) of the insulation from
all of the control wires. (See Figure 2.)
4. Connect the “common” wire(s) to one of the
solenoid wires with a wire nut and install into
a waterproof grease cap (both provided).
(See Figure 3.)
5. Repeat for the station output “hot” wire(s).
(See Figure 3.)
6. Fold and tuck the wire connections into the
compartment pocket.
7. Replace cover and install the three (3) cover
screws (from accessory kit). Tighten to 25 in/
lb. (34,6 kilogram force meters) max or
medium torque setting on a battery-powered drill.
