Hunter has been on the leading edge of golf
irrigation for more than three decades. We
build performance, reliability, and serviceability
into every product we make.
Now, we are proud to advance our legacy of
industry rsts with TTS-800 Series rotors — the
most innovative and technologically advanced
gear-driven rotors on the market. TTS-800
rotors provide maximum uniformity and
longevity in the eld. The high-torque gear
drives are the strongest in the industry, so
the challenges of reclaimed water use or poor
water quality are mitigated.
Our full-line family of TTS-800 rotors provides
best-in-class solutions for any golf course,
anywhere around the globe. These rotors have
all the features expected by superintendents
along with several capabilities never available
before in a golf rotor, like an extra-large ange
compartment and proprietary Filter Sentry
technology that scours the lter clean during
every opening and closing cycle.

Installation Details
Wiring Diagram
The diagram below illustrates wiring connections for two-way module systems.
Installation Best Practices
A. Adjust the swing joint to level the top
surface of the rotor body with the nished
grade. Backll the area around the body
with sand for proper drainage and tamp
down the soil to prevent settling.
B. Solenoid and two-way module
connections are designed to be made
inside the ange compartment using
DBRY-6 waterproof connectors.
C. Leave enough slack in the wire to make
any needed future adjustments.
D. All models have 1½" (40 mm) Acme
threaded inlets. Do not use NPT or BSP
threaded ttings to connect TTS-800
rotors. Adapters are available to attach
NPT or BSP swing joints to Acme threads.
E. Rotate the TTS-800 rotor body clockwise
to tighten by hand until it bottoms out.
Then unwind a half-turn to allow for
minor adjustment aer installation. Acme
threaded inlets come with an O-ring to
create a seal. Do not use Teon tape,
PVC cement, or other thread sealant
to connect as these products can
deteriorate the tting and cause leaks.
