Toro DT34 Installation Procedure, Constructing Swing Joints, Connecting Hydraulic Control Tubing

Installation Procedure ___________________________________________________

To assure maximum performance from your 800S series sprinklers, read these instructions completely prior to installation or service.

Constructing Swing Joints

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

Figure 1

3. Apply PTFE tape on riser threads (not required on ACME threads). Install sprinkler to riser and tighten.

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

Connecting Control Wires (Electric Models Only)

1.Route control wires to sprinklers. Provide extra wire at sprinkler to allow for height adjustment. One common wire and station wire is required for each sprinkler. See Wire Sizing Chart, Table 1 for proper application.

Note: Wire length data provided in Table 1 is the sum of the station and common wire legs. See example in Figure 2.

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

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

Connecting Hydraulic Control Tubing

1.Route control tubing from the controller to the 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. Refer to Table 2 for tubing run length and sprinkler elevation information.

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

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

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

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