Installation Procedure, Servicing the Sprinkler

Installation and Service Instructions

640 Series Rotary Sprinkler

Installation Procedure

To assure maximum performance from your 640 Series Rotary Sprinklers, read these instructions completely prior to installing or servicing the sprinkler.

Construct Swing Joints

1.Construct 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.

3.Apply Teflon™ tape on riser threads. Install sprinkler to riser and tighten.

CAUTION

Use only Teflon tape on riser threads. Use of pipe dope or other types of sealing compounds can cause deterioration of plastic threads and components.

4.Install sprinkler on riser. Align part-circle heads by rotating sprinkler body on riser until radius adjustment slot on top of the nozzle rubber cover is positioned to the left side of the intended coverage area.

5.Valve-In-head models only: Remove tube retainer and cap from sprinkler fitting. Provide a service loop in control tube at sprinkler to prevent binding. Slide tube retainer over end of control tube. Push control tube onto sprinkler fitting and secure with tube retainer.

6.Install sprinklers flush with grade to 1/2 in. (0–13mm) below grade.

7.Backfill and compact soil around sprinkler avoiding contact with nozzle assembly.
