Installation Instructions

INSTALLATION

The PAC525/526 is intended for use both in installations
where an existing finished drywall wall is present, and where
the wall surface has not been finished and the structural studs
are exposed. The wall then must be finished around the
opening of the box after the box has been installed.

WARNING: All wiring should be performed

by a licensed electrician following all local
codes and ordinances.

PAC525/526 Project Planning

1

Identify a suitable wall location for the accessory.

2

Using a stud sensor, locate and mark studs.

3

Identify possible structural conflicts (electrical wiring,
plumbing, gaslines, HVAC).

WARNING: ELECTRICAL SHOCK HAZARD! CUTTING

OR DRILLING INTO ELECTRICAL WIRES OR CABLES
CAN CAUSE DEATH OR SERIOUS PERSONAL INJURY!
ALWAYS make certain area behind mounting surfaces is
free of electrical wires and cables before cutting, drilling or
installing fasteners.

Plan box and component needs.

PAC5 2 6

WARNING: EXPLOSION AND FIRE HAZARD! CUTTING

OR DRILLING INTO GAS PLUMBING CAN CAUSE
DEATH OR SERIOUS PERSONAL INJURY. ALWAYS
make certain area behind mounting surfaces is free of gas,
water, waste or any other plumbing before cutting, drilling
or installing fasteners.

4

Determine installation type. Housing is designed to fit
between two adjacent wall studs, or onto a 1/2” minimum
thickness drywall surface.

Drywall attachment only

Stud & drywall attachment

6

Determine all components needed.

PAC525/526 Site Preparation

7

Using a level, draw a horizontal line at lower edge of
install site.
A - STUD ATTACHMENT - create exploratory hole to
confirm edge of stud/studs.
B - DRYWALL ATTACHMENT - mark horizontal cut
locations ensuring a minimum 1/2” distance from
each stud.

A

B B

Align on lower edge drawn line (A) and horizontal

8

marking for inside stud location (B).Use enclosed
template or housing as a template, drawing line
around top and sides of housing.

PAC525/526 Box Preparation

Remove knock-outs in box as predetermined in

11

step 5.

Loosely attach components and conduit (cut to length)

12

to box to ease fitting into wall opening.

Use four #6 screws (F)
and nuts (G) to assemble
the switch box from either
inside or outside the
PAC525 or PAC526.

A

9

Cut along outside
edge of line using
utility knife.
Remove drywall.

NOTE:
Cutting past corners
weakens the cleats’
ability to hold securely.

10

Mark the four corners.

B

Once wall opening is completed, check stud depth. If 3.5” or greater, proceed to step 11. If less than 3.5” deep, modify depth
of box as follows before proceeding: CAUTION:

B

A

Injury may occur on sharp edges. Carefully discard the removable tabs.

PAC525/526 Box Installation

13

Feed attached conduit through cut-out and insert box
into opening in wall. Tighten component connections.

A - Remove box flange by removing screws.

B - Snap off removable tabs
at perforations provided.

CAUTION:

Avoid sharp edges.

C - Reinstall box flange. Reattach screws.

PAC525/526

Installation Instructions

14

Secure box into
place by methods
chosen.

DRYWALL
ATTACHMENT:

Slide locking
cleats into place.
Tighten screws
to secure.

STUD ATTACHMENT:

Drill pilot holes (optional) into studs through mounting
holes in box. Wood studs - use 3/16” bit. If steel studs

- use 1/4” bit. Install with 1/4 - 20 x 2 1/2” screws (E)
and 3/8” flat washers (H) into pilot holes.

PAC525/526 Final Finishing

16

Using preferred attachment method (zip ties, bands, etc. ­none included), secure AV components and cables within
the wall box. Attachment methods may use integrated
attachment points at back of wall box or other appropriate
points.

Install template as temporary cover if needed to protect

17

from debris by folding tabs in and inserting into opening.

15

NOTE:
Box may be installed with outer flange removed
for a pre-sheetrock open stud mount configuration.

NOTE:
Save flange for
reattachment after
sheetrock is installed.

NOTE:
Locate front edge of box extended
beyond studs by thickness of
sheetrock to be used.

Modify enclosure cover before attaching. Break away tab(s)

18

to allow wire exit from box and meet ventilation needs.

Gather wires and route through cover opening. Install

19

cover, screw fasteners(2) into place to secure and
complete enclosure.
