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 ex 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 nished 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 read Notes
!
!
!
e ACME thread golf sprinkler body requires an ACME thread swing joint for connection to the piping system. e ACME swing joint has an o-ring on the exit tting that provides a water-tight seal inside the sprinkler body when properly assembled.
CAUTION: With the ACME tting, do not use thread sealants such as
Teon™ 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 tting until it stops. No further adjustment is required.
CAUTION: Leakage between the swing joint exit tting 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 o and relieve system water pressure.
2. Remove the sprinkler from the swing joint tting.
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
e GDC system provides a coded DC signal over a polarity sensitive color coded communication cable that requires correct connections to ensure proper operation. e 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.)
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. Ax one to the cover for temporary future reference and the other to the location identication 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
e eld 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 specic 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. e 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.
