Installation Procedure _____________________

CAUTION Golf sprinklers are intended for installation at grade with full support of the body and piping system from the surrounding earth. Failure to provide full support may result in premature failure of the body and/or connecting fittings.

To assure maximum performance from your 734 Series Rotary Sprinklers, read these instructions completely prior to installation or service.

Swing Joints

1. Construct or provide triple swing joints for each sprinkler as shown in Figure 1. Use PVC or ABS pipe nipple for sprinkler connection.

Note: On sites where the possibility of heavy equipment rolling over a 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 new turf is established, the swing joint allows sprinkler repositioning without changing risers. This is a common and practical procedure which eliminates the problem of dirt being accidentally introduced into the lateral lines when a riser is changed.

2. Flush lines thoroughly prior to installing sprinkler.

NPT and BSP Threaded Models

• Apply plumbing tape on riser threads. Install sprinkler onto riser

and tighten.

ACME Threaded Models

• Install ACME threaded bodies onto Acme threaded swing joint

by threading clockwise until hand tight

Note: ACME threaded swing joints have an o-ring that seals to the sprinkle. Plumbing tape is not required..

CAUTION Use only plumbing tape on riser threads. Use of pipe dope or other types of sealing compounds can cause deterioration of sprinkler body threads.

Connecting Electric Control Wires

1. Route control wires to sprinkler location(s). Provide enough extra wire at sprinkler to allow for movement of sprinkler without straining wire connections. One common wire and station wire is required for each sprinkler. See Wire Sizing Chart,

Table 1 for proper

application.

2. Attach control wires to solenoid leads using an approved waterproof splicing method.

CAUTION All wires must be waterproofed to prevent short circuit to ground and subsequent controller damage.

Connecting Hydraulic Control T ubing

1. Route control tubing from controller to sprinkler location(s).

NOTE:

❚ Leave an 18" (45.7 cm) service loop of tubing at each

sprinkler to facilitate movement of sprinkler and service operations.

❚ Tubing runs in excess of 1,000' (304.8 m) are not

advisable due to delayed response time.

❚ The valve elevation for normally open valve-in-head

systems should not exceed 25' (7.6 m) above controller elevation or 70' (21.3 m) below controller elevation.

❚ The valve elevation for normally closed valve-in-head

systems should not exceed 0' above controller elevation or 70' (21.3 m) below controller elevation.

❚ If connecting more than one VIH sprinkler per control

tubing run, refer to the chart below.

2. Flush tubing thoroughly to remove all air and debris.

3. Remove tube retainer and poly cap from tubing adapter at base of sprinkler.

4. Slide tube retainer over control tubing and attach tubing to adapter.

5. Slide tube retainer over adapter area to secure tubing.

System Start-Up

The following is a recommended procedure that will protect system components during system start-up. The procedure is based on a velocity fill rate of less than 2' (0.6 m) per second. See Table 2 below.

1. Use jockey pump only to fill system at velocity fill rate of less than 2' (0.6 m) per second.

2. Use quick coupler keys at all tees and greens with quick coupler valves to bleed air from system lines during filling process. Do not compress air and then relieve, bleed air while filling system.

3. After water has filled all lines and all air is removed, remove quick coupler keys.

CAUTION Failure to comply with recommended fill rate will increase line pressure resulting in a water hammer effect that could damage sprinklers and/or piping system.
