Preparing the Routing Template

Extron offers a metal routing template for the HSA 822,

part number 70-191-01. Extron recommends using this template as a guide to cut the hole in the table where the HSA will be installed.

NOTE: The metal routing template is reusable. Save it for future HSA 822 installations.

1.Cut 1/2-inch x 4-inch strips of soft, finished lumber long enough to span the distance between the desired installation location on the table or other mounting surface and the edges of the table (see figure 3).

These strips raise the routing template above the mounting surface to provide room for the collar of the router, protect the mounting surface, and extend the reach of the routing template so that it can be clamped to the edge of the surface.

2.Using four or more short wood screws, secure the routing template to the lumber strips.

CAUTION: Do not allow the wood screws to protrude through the bottom of the wooden strips. Protruding screws will mar the table when the template is used.

Preparing the Table and Mounting the Enclosure

The preferred and recommended method for preparing the table is to use the appropriate Extron metal routing template and a router.

Alternatively, you can use a paper cut-out template (see “Reference Information”) and a sabre saw or keyhole saw, but this method is not recommended.

Prepare the table as follows:

CAUTIONS: • The opening in the table for the HSA 822 should be cut only by licensed and bonded craftspeople. Exercise care to prevent scarring or damaging the furniture.

•The routing templates for the various HSA models are not interchangeable. If you use the wrong template, you will cut an improperly-sized hole. If you use a larger template than required, the cut will result in gaps in the table surface on either side of the enclosure.

•The surfaces of the HSA enclosure have screws and other protruding hardware that could damage fine furniture. Do not rest the enclosure on unprotected furniture.

NOTE: The metal routing template is reusable. Save it for future HSA 822 installations.

1.Locate the desired mounting location on the tabletop or other installation surface. Mark the location.

CAUTION: Ensure that only the wooden strips contact the furniture. Failure to do so may mar the furniture.

2.Place the routing template assembly on the table, centered on the mounting location. Angle the template for the optimum positioning. If necessary, use a square to ensure that the template is properly positioned. Extron is not responsible for improperly-positioned HSA products.

3.Once the template assembly is positioned properly, secure the assembly to the table with C-clamps (see figure 4, on the next page).
