Construct or provide triple swing joints for each sprinkler as shown inFigure 1. Use PVC or ABS pipe nipple for sprinkler :On sites where the possibility of heavy Equipment rollingover a sprinkler exists, the swing joint will flex preventing damage tothe lateral or main lines.

5 On a new installation in raw ground wherethe Sprinklers are to be initially installed above the finished grade andlowered when new turf is established, the swing joint allows sprinklerrepositioning without changing risers. This is a common and practi-cal procedure which eliminates the problem of dirt being accidentallyintroduced into the lateral lines when a riser is Flush lines thoroughly prior to installing Apply Teflon tape on riser threads. Install sprinkler to riser only Teflon tape on riser threads. Use of pipe dope or othertypes of sealing compounds can cause deterioration of sprin-kler body Electric Control Wires1. Route control wires to sprinkler location(s). Provideenough extra wire at sprinkler to allow for movement ofsprinkler without straining wire connections.

6 One commonwire and station wire is required for each sprinkler . SeeWire Sizing Chart, Table 1for proper Attach control wires to solenoid leads using an approvedwaterproof splicing wire connections must be waterproofed to pre-vent short circuit to ground and subsequent con-troller Hydraulic Control Tubing1. Route control tubing from controller to sprinkler location(s).NOTE: Leave an 18" (45,7 cm) service loop of tubing at eachsprinkler to facilitate movement of sprinkler and serviceoperations. Tubing runs in excess of 1,000' (304,8 m) are not advis-able due to delayed response time. The valve elevation for normally open valve-in-headsystems should not exceed 25' (7,6 m) above controllerelevation or 70' (21,3 m) below controller elevation. The valve elevation for normally closed valve-in-headsystems should not exceed 0' above controller elevationor 70' (21,3 m) below controller elevation.

7 If connecting more than one VIH sprinkler per control tub-ing run, refer to the chart below. 2. Flush tubing thoroughly to remove all air and Remove tube retainer and poly cap from tubing adapter at base of Slide tube retainer over control tubing and attach tubing to adapter. 5.

The procedure isbased on a velocity fill rate of less than 2' ( m) per second. See Table 2 Use jockey pump only to fill system at velocity fill rate of less than 2' ( m) per Use quick coupler keys at all tees and greens with quick coupler valves to bleed air from system lines during fillingprocess. Do not compress air and then relieve, bleed air while filling After water has filled all lines and all air is removed, remove quick coupler to comply with recommended fill rate will increase line pressure resulting in a water hammer effectthat could damage 2 Recommended System Fill RatePilot Valve Operation (Models 674-X6-XXX and 674-X8-XXX Only)The main function of the pilot valve is to control the operation of the main valve located in the base of the sprinkler main valve is operated by the release of water metered through the pilot valve when it is activated either manually atthe sprinkler or by the irrigation system important function of the pilot valve is to regulate the water pressure to the sprinkler nozzle.

9 Pressure regulationcompensates for large variations within the system and maintains a constant pressure for optimum sprinkler operation. Thepilot valve is factory set to regulate one of four pressure levels 50 PSI ( kg/cm2), 65 PSI ( kg/cm2), 80 PSI ( kg/cm2)or 100 PSI ( kg/cm2).NOTE: Sprinklers built between 1986 and 1988 utilized an adjustable pilot valve assembly. Although factory-set at 100 PSI( kg/cm2) regulating pressure, the pilot valve can be set to regulate between 40 120 PSI ( kg/cm2) to compen-sate for various field conditions. See Adjusting Pressure Regulation on page 11 for more sprinkler operation mode is set using a Toro Selector Tool (P/N 995-15) inserted through the body flange onto the pilotvalve D-shaped selector cam. The "AUTO" mode permits automatic operation from the system controller.
