Installation
NOTE:
Refer to local building standards and codes to verify that
the installation will meet the regulatory requirements. Observe all
local and national building and safety codes, UL requirements,
and ADA accessibility guidelines.
Before installation identify the type of wall (masonry or non-masonry)
and the location where the WMK 160 will be installed. This determines
the installation approach and type of fasteners needed to secure the
plate to the wall.
Step 1.
—
Mount the Base Plate
Follow the steps within
1A
or
1B
, as applicable.
NOTE:
The base plate can be installed over an existing electrical
outlet (see figure 2 at right).
1A. To mount the WMK 160 onto masonry walls:
i.
Hold the base against the wall, level it, and mark the
positions of four slotted mounting holes (indicated by
+ marks in figure 2
at right). Set the plate aside.
ii.
Using a masonry drill bit, drill 1¾ inch (4.4 cm) deep
pilot holes at the marked locations.
iii.
Screw in ¼ x 1¾ inch masonry screws (not supplied)
until a gap of about 3/8 inch (9 mm) remains between
the wall and the screw heads.
iv.
Align the slotted mounting holes of the base plate
over the installed screws, then slide the plate
down so the screws fit into the slots (see figure at
immediate right).
v.
Verify level and position and tighten all the screws to secure the plate flush to the wall.
Proceed to step 2.
1B. To mount the WMK 160 onto a non-masonry wall:
i.
At the desired site, locate and mark the wall studs.
NOTES:
•
For ideal installation secure the base plate to at least
one wall stud (see
at right). Drywall KapToggles
can be used for holes not aligned with studs.
•
Always use the widest spacing of screws and
KapToggles.
•
The base plate can be installed over an existing
electrical outlet (see figure 2 above).
ii.
Hold and level the base plate against the wall and mark
the positions of the slotted mounting holes that are on
the stud lines (see
indicated by + marks). Where
applicable, mark the mounting holes on the wall for
drywall toggles.
