Introduction ____________________________________________________________________
The DT35 and DT55 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, these 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.
Features ________________________________________________________________________
