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.

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

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 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.

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.
