Introduction _____________________________________________________________________
The 835S and 855S series full-circle/adjustable part-circle rotary sprinklers are
designed specifically for golf course applications.
Manufactured from durable, high-strength engineering plastic and stainless-steel
components, the 800S series sprinklers incorporate many innovative and time-
proven features for lasting, maintenance-free operation.
Prior to installing the sprinkler, read through the recommended installation and
start-up procedures. Please observe all
WARNINGS
and
CAUTIONS
when
installing and operating this equipment.

Arc Adjustment Procedure ________________________________________________________ The 835S and 855S sprinkler models can be operated in full-circle or part circle operation. In part-circle operation, the sprinkler arccan be adjusted from 40°– 330°. When full-circle (360°) operation is selected, the ...
Main Valve PROBLEM POSSIBLE CAUSE – CORRECTIVE ACTION Valve won't close (a) Continuous 24 VAC to sprinkler. (Electric ) – Check controller for voltage source. (b) Leak in pilot valve assembly. – Replace pilot valve assembly. (c) Plugged supply screen on piston. – Clean or replace screen. (d) Manual ...
