4. Set the bracket aside temporarily, and drill holes at the marks you made on the
wall.
Note:
The diameter of the holes you drill must match the
hardware you are using to mount the Sunny Boy. For example,
if you are mounting the Sunny Boy on a concrete wall, the hole
diameter should be approximately the same as the outside
diameter of the concrete anchors you intend to use. If you are
mounting the Sunny Boy on a wall that has wooden studs inside
it, the hole diameter should be the correct size for the lag screws
you intend to use to mount the bracket. If you are installing the
Sunny Boy outside, the lag screws must be made of stainless
steel, and the diameter of the screws should closely match the
diameter of the holes in the wall-mounting bracket. If you use
M6x10 or 1/4” screws, drill
7/32
-inch pilot holes.
5. Insert two stainless-steel lag screws through the holes in the horizontal part of the
wall-mounting bracket and into the holes you drilled in the wall. Tighten the screws
until the bracket is held firmly against the wall (see #1 in Figure 3-4). Do not over-
tighten the screws.
6. Carefully lift the Sunny Boy into position near the mounting bracket. The upside-
down, U-shaped bracket attached to back of the Sunny Boy at the top edge fits over
the top edge of the bracket so that the Sunny Boy hangs from the bracket (see #2 in
Figure 3-4).
WARNING: To avoid injury, lift the Sunny Boy carefully, and
handle it carefully to prevent the weight of the inverter from
causing you to lose your balance and fall. If possible, have
someone help you when you mount the Sunny Boy.
7. Inspect the Sunny Boy from both sides to ensure that the U-shaped bracket on the
Sunny Boy fully engages the top edge of the mounting bracket and that the Sunny
Boy is centered on the bracket.
8. Locate the mounting strap that hangs from the back of the Sunny Boy at the bottom.
9. Insert an M6x10 bolt through the hole in the mounting strap and into the threaded
hole in the bottom end of the wall-mounting bracket (see #3 in Figure 3-4).
10.Tighten the bolt fully (do not overtighten).
11.Verify that the Sunny Boy 1100U is firmly mounted in place.
