ST-1600-Kit Support

Incoming Plumbing Location

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 valve Manifold inlet is centered along the right side wall of the Vault’s upper rim. While this is the standard angle for the Manifold, the Manifold can be pivoted within the Vault to adjust for minor angular variances in the rigid sub-mainline piping that will be attached to the Manifold.

The quick coupler inlet piping must be plumbed to align with the quick coupler’s Quick Access Port 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 cover set once they are installed. The quick coupler inlet piping needs to extend vertically to a position directly below the Quick Access Port (#12) in the Vault’s cover set. If the quick coupler is too low it will be impossible to attach the key to the quick coupler.

The depth and location of the rigid piping connected to the inlet of the Manifold are critical. Use the Side View of the installation detail on the following page as a reference. Note that the Manifold’s inlet is approximately 24" (61 cm) to 30" (76 cm) from the top of the Vault. The mainline should also be at this approximate depth unless specified otherwise.

The quick coupler’s inlet piping (#14) must align with the quick coupler access hole in the Vault’s cover set (#20). Also, in order for the quick coupler key to operate properly with its handle attached, the quick coupler 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 1⁄2" (1.5 cm) below the underside of the Vault’s main cover (#20).

IMPORTANT: The pipe size to the manifold must be at least 3" (80 mm) from the mainline through to the manifold assembly.
