MODEL NUMBERING SYSTEM

TTS Rotors – All Models
Hunter TTS golf rotors are available in two basic
body styles. The G800 Series and the G900
Series rotors. Each of these body styles is
available in either the Check-O-Matic (COM)
valve configuration, the Electric Valve-In-Head
(EVIH or more commonly known as VIH) valve
configuration and the Decoder-In-Head (DIH)
valve configuration:
G800C = a G800 body in a COM valve configuration*
G800E = a G800 body in a VIH valve configuration
G800D = a G800 body in a DIH valve configuration
G900C = a G900 body in a COM valve configuration*
G900E = a G900 body in a VIH valve configuration
G900D = a G900 body in a DIH valve configuration
Combining a body style, gear-driven riser and valve
configuration together creates a model number
system that clearly defines the primary
characteristics of the rotor:
Examples
G875C = a G800 body with a G75 adjustable riser
and a COM valve
G990E = a G900 body with a G90 full-circle riser
and a VIH valve
* All COM TTS rotors can be converted to the Normally
Open Hydraulic configuration.

Each body style will accept specific
gear-driven risers:
G835 = G800 body style fitted with a G35
adjustable part-circle riser
G870 = G800 body style fitted with a G70
full-circle riser
G875 = G800 body style fitted with a G75
adjustable part-circle riser
G880 = G800 body style fitted with a G80
full-circle riser
G884 = G800 body style fitted with a G84
full-circle riser
G885 = G800 body style fitted with a G85 adjustable
part-circle riser
G990 = G900 body style fitted with a G90
full-circle riser
G995 = G900 body style fitted with a G95
adjustable part-circle riser

INSTALLATION AND OPERATION

Pipe Connections – All Models
All TTS rotors have a 1½" Acme threaded inlet. Acme inlet threads have become the preferred
thread configuration in the golf course irrigation market.
to connect piping to TTS rotors. Acme threads are not compatible with NPT or BSP fittings. Acme
threaded fittings and swing joints are available from your local irrigation supply company. Following
are the available options for connecting TTS rotors to the irrigation system piping:
• PVC swing joints with a 1½" male Acme
outlet fitting.
• Approved flexible swing joints with a 1½" male
Acme outlet fitting.
• Replace the final fitting of the existing swing
joint with a 1½" male Acme outlet fitting
(fitting must be the same brand as
swing joint).
• Use the appropriate Hunter Acme Adapter
fitting. These are available from Hunter
distributors in various NPT and BSP sizes
(Teflon™ tape or PVC cement must be used
between the connecting NPT or BSP threads).
use Teflon™ tape, PVC cement or other thread
DO NOT
sealant materials to connect the TTS rotor to the Acme
fitting. If needed, a small amount of Dow Corning™ #111
Valve Lubricant or pure petroleum jelly like Vaseline™ can
be used around the O-Ring on the Acme fitting. Other
lubricants can deteriorate the fitting and cause leakage.
Thread the Acme fitting into the TTS rotor clockwise by
hand until it bottoms out (no further rotation is possible).
Then turn the fitting in reverse (counter-clockwise) ½ to 1
turn. The fitting will still seal around the O-Ring and this
loosened position will allow minor rotation of the rotor's
body after installation.
