INSTALLATION
WARNING: DO NOT INSTALL THIS ACCESSORY IN A
FIREWALL. Contact your local building inspector before
cutting a hole in the drywall if unsure.
WARNING: IMPROPER INSTALLATION CAN RESULT IN
DEATH OR SERIOUS PERSONAL INJURY! This accessory
should be installed by qualified personnel.
Locate and Prepare Mounting Site
1. Identify a suitable wall location for the in-wall enclosure.
IMPORTANT ! : The PAC501 is designed for in-wall
installation spanning a minimum of three wood or steel studs,
16" on center. Installation of PAC501 in 2" x 4" wall results in
nearly direct contact with vertical studs and back wall.
Inadequate space will remain for electrical wires/cables,
plumbing, ductwork, or insulation. Locate installation
accordingly.
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.
Frame Housing
Wood Studs
The exposed portion of the center wood stud must be removed
and the resulting cavity completely framed with wood. The
following steps are suggested. The actual procedure is
dependent upon the specific installation.
WARNING: STRUCTURAL FAILURE HAZARD! FAILURE
TO TAKE ADEQUATE PRECAUTIONS CAN LEAD TO
DEATH OR SERIOUS INJURY! Ensure removal of center
stud will not cause unacceptable loss of structural strength.
Consult a qualified building contractor and applicable building
codes.
1. Remove exposed portion of center wood stud flush with
upper and lower drywall edges.

3. Using three #10 x 2-1/2" countersunk wood screws (not
included), attach each support block to the studs (See
Figure 2)
NOTE: Ensure screws are far enough from block end to
prevent interference with framing screws installed in InWall Enclosure Installation section.
4. If necessary, cut rectangular hole in horizontal framing to
accommodate a UL Listed electrical box accessory (not
included).
5. Attach horizontal framing to each support block with two
#10 x 2-1/2" countersunk wood screws (not included). (See
Figure 2)
