Installation

2.3Flush-Mounting the AC4

NOTE

Removing the conduit knockouts before mounting the AC4 on the wall will ease installation and prevent strain on the mounting hardware and wall. It is imperative to remove the knockouts if the unit is to be flush-mounted.

The rectangular access doors on the top and bottom of the AC4 must be reversed so they slide the opposite direction. Leaving the doors as shipped from the factory prevents them from being opened when the panel is flush mounted in a wall.

The AC4 may be flush mounted according to company practices—either with screws through the sides of the panel into wall supports or with hanging hardware that attaches to the back of the panel. After determining how and where to place the unit, check to ensure that you have all the hardware required to install the panel in the wall. Obtain the needed tools.

Required tools

• Saw

• Electric drill

• Screwdriver

• Marker to denote layout of the hole to accommodate the AC4

• Trim ring and associated hardware

• Mounting hardware

2.3.1 Mounting the Panel

! CAUTION

Check building plans and other relevant documents to determine whether mounting the AC4 at the selected location might cause cutting or otherwise damaging electrical or communication wiring or pipes.

1.Mark the wall for the cutout to accommodate the panel, using the back of the unit as a template.

2.Drill a pilot hole for the saw blade, if required.

3.Use the saw to cut out the marked section of the wall (if not new construction).

4.Rest the AC4 in the wall and mark where mounting screws will be inserted into the wall studs or other support member.

5.Remove the panel and drill the holes for the mounting screws or wall anchors. Clean up the debris.

6.Reverse the slide direction of the rectangular access doors on the top and bottom of the AC4. Leaving the doors as shipped from the factory prevents them from being opened when the panel is flush mounted in a wall.

7.Attach any field-supplied mounting hardware.

8.Reinsert the assembly into the wall.

9.Insert and tighten the screws or wall anchors.
