TABLE OF CONTENTS I INSTALLATION & OPERATION
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 conguration, the Electric Valve-In-Head
(EVIH or more commonly known as VIH) valve
conguration and the Decoder-In-Head (DIH)
valve conguration:
G800C = a G800 body in a COM valve conguration*
G800E = a G800 body in a VIH valve conguration
G800D = a G800 body in a DIH valve conguration
G900C = a G900 body in a COM valve conguration*
G900E = a G900 body in a VIH valve conguration
G900D = a G900 body in a DIH valve conguration
Each body style will accept specic
gear-driven risers:
G835 = G800 body style tted with a G35
adjustable part-circle riser
G870 = G800 body style tted with a G70
full-circle riser
G875 = G800 body style tted with a G75
adjustable part-circle riser
G880 = G800 body style tted with a G80
full-circle riser
G884 = G800 body style tted with a G84
full-circle riser
G885 = G800 body style tted with a G85 adjustable
part-circle riser
G990 = G900 body style tted with a G90
full-circle riser
G995 = G900 body style tted with a G95
adjustable part-circle riser
• PVC swing joints with a 1½" male Acme
outlet tting.
• Approved exible swing joints with a 1½" male
Acme outlet tting.
• Replace the nal tting of the existing swing
joint with a 1½" male Acme outlet tting
(tting must be the same brand as
swing joint).
• Use the appropriate Hunter Acme Adapter
tting. These are available from Hunter
distributors in various NPT and BSP sizes
(Teon™ tape or PVC cement must be used
between the connecting NPT or BSP threads).
Following are the minimum recommended
swing joint sizes for TTS rotors. However, follow
your Irrigation Consultant’s recommendations
where applicable:
• G800 Series rotors with nozzles #2 thru #18 -
1” swing joint with 1 ½” Acme outlet tting
• G800 Series rotors with nozzles #20 thru #25 -
1 ¼” swing joint with 1 ½” Acme outlet tting
• G800 Series rotors with nozzles #25 thru #53 -
1 ½” swing joint with 1 ½” Acme outlet tting
• G900 Series rotors with nozzles #25 thru #73 -
1 ½” swing joint with 1 ½” Acme outlet tting

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 conguration.
Combining a body style, gear-driven riser and valve
conguration together creates a model number
system that clearly denes the primary
characteristics of the rotor:
INSTALLATION AND OPERATION
Pipe Connections
–
All Models
All TTS rotors have a 1½" Acme threaded inlet. Acme inlet threads have become the preferred
thread conguration in the golf course irrigation market. Do Not use NPT or BSP threaded ttings
to connect piping to TTS rotors. Acme threads are not compatible with NPT or BSP ttings. Acme
threaded ttings 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:
DO NOT use Teon™ tape, PVC cement or other thread
sealant materials to connect the TTS rotor to the Acme
tting. 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 tting. Other
lubricants can deteriorate the tting and cause leakage.
Thread the Acme tting into the TTS rotor clockwise by
hand until it bottoms out (no further rotation is possible).
Then turn the tting in reverse (counter-clockwise) ½ to 1
turn. The tting will still seal around the O-Ring and this
loosened position will allow minor rotation of the rotor’s
body aer installation.
