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 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

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

• 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).

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 fitting

• G800 Series rotors with nozzles #20 thru #25 -
1 ¼” swing joint with 1 ½” Acme outlet fitting

• G800 Series rotors with nozzles #25 thru #53 -
1 ½” swing joint with 1 ½” Acme outlet fitting

• G900 Series rotors with nozzles #25 thru #73 -
1 ½” swing joint with 1 ½” Acme outlet fitting

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.

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:

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.

Do Not

use NPT or BSP threaded fittings

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:

DO NOT

use Teflon™ tape, PVC cement or other thread

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.
