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 24" (61 cm) deep, 36" (91 cm) long, and 36" (91 cm) tall. The body of the vault weighs 170 lb (77 kg), and the complete vault with the covers weighs a total of 320 lb (145 kg). The vault has two ports for easy access to the quick coupler and the on-off-auto selector switch. The elevation to the grade of the vault must be precise. It’s determined by the field and irrigation specifications. In many installations, the vault’s elevation is specified such that the upper rim of the vault is level with the upper rim of the tack glue board surrounding the field. The type of material, if any, that attaches to the vault’s upper surface may also affect the vault’s elevation. This can include the field’s synthetic material or the adjacent running track material.
Tack glue board around the vault:
To begin the installation, configure the vault according to the specifications provided by the irrigation consultant. It must rest upon a compacted base material per the field specifications. For the vault to drain properly, it needs access to the drainage system. The drainage system must be lower in elevation than the vault’s 36" (91 cm) depth to keep water from pooling inside the vault. If the vault is set directly on gravel within the drainage system, the gravel should be compacted, and the vault should be set upon six or more bricks for stabilization. After leveling the vault, you may want to pour a concrete curb around the outside of the base and the inside corners for stabilization.
