3.4 Wall Mounting Base Cabinet
3.4.1 Base Cabinet Installation Instructions
If the cabinet mounting holes align with wall studs, the
cabinet can be installed directly on the wall (Figure
3-4). For more than two cabinets, a wooden
backboard between the cabinet and the wall
is
highly
recommended (Figure 3-5).
Install the base cabinet per the following
steps:
1.
If using a backboard: Obtain a board, such as
plywood, that is at least 3/4
of
an inch thick. The
board should be at least five feet high (completely
expanded systems with six cabinets require this
much height) and two feet wide (minimum).
Secure the board to the wall with wood screws so
that the bottom edge of the board is six inches
above the floor.
(If there are studs behind the wall,
make sure the wood screws align with the studs.)
2. Remove the front, back, and side covers from the
base cabinet (Figure 3-6).
Note:
As shown in the illustration, the two screws on
each side cover and the three screws on
front cover (the bottom left screw must be
completely removed) should only be loosened
and the covers slid to the right for removal.
3. Hold the base cabinet back cover against the wall
or backboard so that its two top mounting holes
are
feet (66 inches) above the floor (Figure
3-8). This will allow six cabinets to be installed

(top-down) with a six-inch clearance between the
floor and bottom cabinet.
Use a level to make sure that the back cover
is
held level.
Make a mark with a pencil in the marking holes on
both sides of the top mounting holes (Figure 3-8).
Trace the upper arch of the top mounting holes.
Remove the back cover from the wall.
For both mounting holes, draw a line between the
top two marking hole marks (Figure 3-8).
Drill holes on the line in the middle of the arch
tracing.
Screw #12 X 1.25 inch size wood screws into the
two drilled holes, leaving about of an inch
clearance between the screw heads and the wall.
Hang the base cabinet back cover from the top
two screws and secure the screws into the wall.
Drill holes at the bottom two mounting holes of the
back cover, and secure
X 1.25
inch
wood
screws into the two holes.
If installing just a base cabinet: Position the base
cabinet on the back cover cabinet hangers, slide
the cabinet to the right to the proper mounting
position, and secure the cabinet to the back cover
with two screws on the right side of the cabinet
(Figure 3-9). If installing expansion cabinets, skip
to Subsection 3.4.2.
Install ground wiring per Section 3.6, power (AC
and reserve) cabling per Section 3.7 and 3.8, and
printed circuit board (PCB) cabling per
Figures 3-1
0, 3-1 2 and 3-1 3.
Fill out the slot identification label on the cabinet
(Figure 3-12).
Reinstall front cover, top cover, and side covers
onto the cabinet (Figure 3-6).
