Installing and Adjusting the Rotor, Manifold Assembly, and Rotor Hanger Bracket

After placing the adjustable support stands in the vault, it’s time to install the rotor and manifold assembly. Use two people to lower the rotor and manifold assembly onto the support stands. If a slight adjustment is needed, you can raise or lower the support stands with these assemblies on them.

With the rotor inside the vault, install the ST-BKT-1600 Rotor Hanger Bracket onto the vault to secure the rotor. There are two halves of the bracket with the supplied bolts and nyloc nuts needed to assemble it.

  1. Set one half with the protruding hanger arms facing upward under the flange of the rotor. Engage the arms on the rim of the vault.
  2. Install the second half, once again confirming that the arms are engaged on the rim of the vault and are under the flange of the rotor.
  3. Once the brackets are loosely fitted to the vault and rotor, slide the bolts through the bracket’s predrilled holes to connect the two bracket pieces, and tighten the bolts and nyloc nuts to loosely grip the rotor. Keep the bracket loose until after the Infill Barrier System is installed and the rotor’s elevation is set.

 

Lower the Rotor and Manifold assembly into the vault. The three arms on the ST-BKT1600 Rotor Bracket need to engage the rim of the Vault. Position the Adjustable Support Stands under the Manifold assembly and align them directly under the selected Manifold couplings. Raise or lower the Rotor within the Rotor Hanger Bracket as necessary to achieve the correct Rotor elevation relative to the adjacent Vault cover. Raise or lower the Adjustable Support Stand's metal rail to fully support the Manifold.

Adjusting Rotor Elevation

​When infill-type synthetic turf is to be attached to the upper surface of the Vault cover set and to the top of the Rotor, the upper surface (floor) of the installed IBS center cup needs to be the same elevation as the upper surface of the Vault’s cover set. Using Hunter approved adhesive, attach the turf material to the IBS central cup.

When pad-type running track material or short-pile non-infill carpet is to be attached to the upper surface of the Vault cover set and to the top of the Rotor, the vertical walls of the IBS kit need to be trimmed to create a flat upper surface. Once trimmed and installed on the Rotor, adjust the upper flat surface elevation to be the same elevation as the Vault’s upper surface. The disc of pad or carpet material to be attached to the IBS needs to be approximately 14-3/8" (36.3 cm) in diameter. It is easier to attach this material to the IBS with the IBS central cover removed from the Rotor. Using Hunter-approved adhesive, attach the pad or carpet material to the IBS central cover. Care needs to be taken to center the IBS central cover under the pad or carpet material. The attachment of the pad or carpet material to the IBS is often the responsibility of the installing turf contractor. It is important to pass this information along to the installer.

When no material is to be attached to the upper surface of the Vault or the Vault is to be covered with the pour-in-place type of synthetic running track material, the vertical walls of the IBS kit need to be trimmed to create a flat upper surface. Once trimmed, attach the ST-FRP-1600 simulated concrete disc to the top of the flattened IBS using Hunter-approved adhesive. It is easier to attach this disc to the IBS with the IBS central cover removed from the Rotor. Once the adhesive has dried, install the trimmed IBS central cover and disc assembly to the Rotor. To set the Rotor elevation, adjust the upper flat surface of the ST-FRP-1600 simulated concrete disc to be the same elevation as the Vault’s upper surface. If the Vault and Rotor are to be covered with the pour-in-place synthetic running track material, it is the responsibility of the installing turf contractor to do this work. It is important to pass this information along to the installer. The Manifold assembly needs to be adjusted with the Support Stands to be approximately horizontally level. Make sure the weight of the Manifold is supported by the two Adjustable Support Stands. The Rotor's inlet is not designed to support the Manifold's weight.
