Installation Steps
-
Installing the vault
The first piece to prepare and install for the kit is the vault. The ST-243636-B Vault is made from construction-grade fiberglass material and houses all the kit components. It’s
-
Incoming Plumbing Location
When installing the kit, it’s crucial to prepare the incoming plumbing location properly. If done correctly, you should be able to easily level the rotor using the predetermined
-
Organize and Assemble the Manifold Components
The ST System’s manifold is made up of the ST-V30-KV Control Valve and the ST-BVF30-K Isolation Valve Kit. The manifold controls and supports the long-range rotor and provides a
-
Assembling Grooved Victaluic™ Type Fittings
When assembling grooved Victaulic type fittings to create the ST Manifold, approved pipe gasket lubricant can be used to aid the assembly process, but it is not required.
-
Flexible Hose Access Through the Vault
The ST Kit’s ST-H30-K Flexible Stainless Steel Hose connects the incoming water supply to the manifold. The flexible hose adjusts for minor elevation and alignment differences
-
Attaching the Rotor and the Quick Coupler Supply Line
After attaching the flexible hose, install the rotor to the manifold assembly. Apply Teflon™ tape or paste to the adapter’s threads. Thread the rotor to the adapter to
-
Configure and Position the Adjustable Support Stands
Once the rotor, manifold, and stainless steel hose are assembled, you’ll need to install the ST-SPT-K Support Stands. Two adjustable stands are required to support the weight of

Installing the Remote On-Off-Auto Selector Switch and Solenoid Assembly
The on-off-auto selector switch allows the user to control the kit to automatically actuate from an irrigation controller or manually from the switch. To install the switch, make
-
Connecting the Control Tubing to the Control Valve
After installing the on-off-auto selector switch, insert the supply tubing from the switch into the control valve. This allows you to turn the valve on and off, either manually
-
Installing the Tack Glue Board
The last thing to install is the tack glue board. After backfilling around the vault, install a tack glue board around the vault’s perimeter. This allows you to securely attach the
