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.
2. Flush lines thoroughly prior to installing sprinkler.
3. Apply Teflon™ tape on riser threads (not required on ACME threads). Install sprinkler to the
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 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.

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.

In part-circle operation, the sprinkler arc can be adjusted from 40°– 330°. When full-circle (360°) operation is selected, the sprinkler will rotate in a clockwise direction only. The arc is factory preset at 180°.
