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. See the part numbers for the templates in appendix A, “Reference Information”.

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

Prepare the table as follows:

	CAUTION		The opening in the table for the HSA 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.
		The metal routing template is reusable. Do not discard
		the template when the installation is complete. Save it
		for installing other HSA products of the same size.
1.	Locate the desired mounting location on the tabletop or
	other installation surface. Mark the location.
			Ensure that only the wooden strips on the routing
	CAUTION
			template contact the furniture. Failure to do so may
			mar the furniture.
2.	Place the mounting 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 (figure 2-2).

Figure 2-2 — Cutting the opening with a router

		Wear safety glasses when operating the router.
		Failure to comply can result in eye injury.
4.	Using a router with a 5/8" (or 16 mm) outside diameter
	guide bushing and a 1/2" (or 12 mm or 12.7 mm) diameter
	straight router bit, carefully cut the opening in the table
	surface (figure 2-2).
5.	Remove the C-clamps and the routing template.
		The flanged edges of the top of the surface enclosure
		are sharp. To prevent personal injury, exercise
		caution when the HSA is not installed in a table.
		The flanged edges of the top of the surface enclosure
	CAUTION
		are bevelled to an ultra-fine thickness of less than

0.04(4/100)" (approximately 1 mm). These edges are soft and can be easily nicked or bent. Exercise caution when handling and mounting the enclosure. Mishandling can damage the appearance of the enclosure.

6. Remove the plastic strips that protect the flanged edges of the top of the surface enclosure. If a sticky residue remains, remove it with an appropriate metal cleaning product.

CAUTION	Do not use isopropyl alcohol or other solvents to
	clean the HSA. Strong solvents will ruin some
	finishes.
