INFINITY™ Series Sprinkler with SMART ACCESS™

Installation and Service Guide

Toro’s new INFINITY Series sprinklers with SMART ACCESS™ are designed specifically for Golf applications and extend and enhance Toro’s industry leading line of Golf sprinklers. Manufactured from durable, high-strength engineering plastic and stainless-steel components, the INFINITY Series sprinklers incorporate many innovative and time-proven features for lasting, maintenancefree operation.

Six base models are available:

•INF34 - 1” (25 mm) ACME inlet, full circle, dual trajectory

•INF54 - 1.5” (40 mm) ACME inlet, full circle, dual trajectory

•INF35 - 1” ACME inlet, full/part circle, dual trajectory

•INF55 - 1.5” ACME inlet, full/part circle, dual trajectory

•INF35-6 - 1” ACME inlet, full/part circle, 24 position TruJectory

•INF55-6 - 1.5” ACME inlet, full/part circle, 24 position TruJectory

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.

Waterproof Wire Splices

!CAUTION: All wire splices and field connections must be waterproofed to prevent short circuit to ground and subsequent controller damage.

This type of waterproofed wire splice is for use with solid and/or stranded wire connections.

1	- 3 #12	1	- 4 #14	2	- 5 #16
2	- 5 #18	1	#10 w/ 1-4 #18	1	#12 w/ 1-4 #18
2	#12 w/ 1 or 2 #18	1	#14 w/ 1-4 #18	3	#14 w/ 1 or 2 #18

Steps

1.Strip wires (12-16 gauge) 7/16” (11 mm)

2.Pre-twisting is unneccessary. Hold stripped wires together with ends even (Figure 1). Lead stranded wires slightly. Align any frayed strands or conductors.

3.Firmly push wire into connector and screw connector clockwise onto wire until tight (Figure 1).

4.Insert the splice to the bottom of the sealant filled tube (Figure 2).

5.Position wires into wire channels (Figure 3). Wipe away any sealant around opening and conductors.

6.Close lid ensuring latch is secured (Figure 4).

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.)

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
	Figure 1						Figure 2
signal to the sprinklers typically using individual
wires. Connections to the sprinkler solenoid in
			access
these systems are not polarity sensitive and do
			grommet
not require specific wire connections. Typically
the “common” wire from the controller is daisy-
chained to multiple sprinklers with one wire
		service loops
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
	Figure 3
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.)
	grease cap

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.

Final Adjustments

Adjust the swing joint to bring the top of the sprinkler flush to grade. Back fill with clean porous material that promotes drainage. Tamp the soil around the sprinkler to compact the soil and prevent settling.
