Synthetic Turf Rotor and Vault System

Incoming Plumbing Location

The Hunter STG-900-KIT synthetic turf rotor and vault system is a special combination of products designed specifically to meet the unique needs of irrigation on synthetic turf fields. Synthetic turf fields are a non-serviceable surface, meaning they are not easily excavated and restored to original condition without huge expense and specialized procedures. As a result and to the extent possible, all serviceable components of the irrigation system must be accessible from the surface. The Hunter STG-900-KIT makes installation and adjustment straightforward and flexible. The STG-900-KIT also provides easy access for the ongoing maintenance needs of the end user.

Setting the ST-173026-B Vault

Set the vault according to the installation specifications provided by the irrigation consultant. It must rest upon a compacted base material per the field specifications. If the vault is to be set directly upon the gravel of the drainage system, the gravel should be compacted and the vault set upon six bricks for stabilization.

The elevation to grade of the vault must be precise and is determined by the field and irrigation specification. In many installations, the elevation for the vault is specified such that the upper rim of the vault is level with the tack/glue board that surrounds the field. The vault’s elevation can also be affected by the type of material, if any, that will be attached to the vault’s upper surface. Sometimes this will be the field’s synthetic “carpet” or the adjacent running track material. Some customers prefer no attachments to the covers because they want a player running toward the vault to see it and take corrective action.

With the STG-900-KIT, there is a direct and required relationship between the location of the vault, the location of the incoming plumbing, and the location and depth of the drainage system. In order for the irrigation sprinkler (rotor) to be properly positioned within the hole in the vault’s cover, the swing joint’s inlet piping must be placed at the specified location and depth. In order for the quick coupler valve to be accessible and functional once installed, the quick coupler’s supply pipe must be installed in the correct location and the valve must be at the correct height within the vault. In order for the vault to drain properly, it must have access to the drainage system, and the drainage system must be lower in elevation than the vault’s base (26" or 66 cm).

The swing joint’s inlet piping location and depth is critical. This location and depth in conjunction with the special multiaxis vertical alignment (VA) swing joint allows the rotor to be placed and leveled within the hole in the vault’s cover. Use the top view of the following installation detail as a reference. The bottom of the top view drawing represents the on-field side of the vault and the top of the drawing represents the off-field side. Next, note that the swing joint inlet is centered along the right side wall of the vault’s upper rim (#23). The swing joint’s inlet piping must not be any closer to the rotor hole in the cover than this location. The swing joint’s inlet can move outward to the point where it is centered under the vault’s upper rim.

The quick coupler inlet piping must align with the quick coupler access hole in the vault’s cover. Use the top view illustration as a reference below. The rim of the vault is the exposed upper surface that surrounds the vault’s covers once they are installed. The quick coupler inlet piping needs to be 5" (12.7 cm) from the inner rim of the vault at the top and 5" (12.7 cm) from the inner rim of the vault on the right side (#24).

Vault Dimensions:

Two-piece cover - Upper Rim 20" x 33" (50.8 cm x 83.8 cm), Cover 17" x 30" (43.2 cm x 76.2 cm),

Depth 26" (66 cm), Base 27" x 41" (68.5 cm x 104.1 cm)

Incoming Plumbing Elevation

Specification List for Installation Detail Drawings

The swing joint’s inlet piping location and depth is also crucial. This location and depth in conjunction with the VA swing joint allows the rotor to be placed and leveled

within the hole in the vault’s cover. Use the side view of the following installation detail as a reference. Note that the VA swing joint’s first horizontal section is resting at a level that is at the same level as the bottom of the vault (#22). This depth is 26" (66 cm) from the top of the vault.

The quick coupler inlet piping (#13) must align with the quick coupler access hole in the vault’s cover (#24). Also, in order for the quick coupler key with its handle attached to operate the quick coupler valve, the quick valve must be installed

as close to the underside of the main cover as possible. Use the side view illustration shown below as a reference. The quick coupler must be installed so that the final elevation is approximately ½" (1.2 cm) below the underside of the main vault cover (#20).
