MODULE INSTALLATION
Install bottom window well module so that it rests
on at, undisturbed soil as shown in Figure 2.
Mount and anchor lower module into position as
instructed below.
Buck Mounting: Utilize the back-out screws
provided in the buck for attachment. IMPORTANT:
Use washers provided with buck (or minimum
3/4” diameter) and a minimum of (3) fasteners
per mounting ange (6 per module) for proper
IMPORTANT
installation. Add fasteners and washers as re-
quired if there are not enough back-out screws to
meet this requirement (see wall mounting instruc-
tions for fastener requirements).
Wall Mounting: Important - maintain a 58-1/4” on
center dimension between the keyholes on each
ange to ensure proper t of the optional well
cover. Anchor module to wall using 3/8” (.375”)
diameter masonry fasteners* with washers* (mini-
mum 3/4” diameter). Fasteners must be designed
for the wall material to which attachment will occur
and be at least 1-3/4” in length.
IMPORTANT: Use a minimum of (3)
fasteners per mounting ange (6 per
module) for proper installation.
Method of attachment must be adequate
to restrain earth loads imposed on the well.

After the rst module is fully anchored, remove the
top inserts so that the next module can be installed.
This is done by removing the retaining screw
and washer as shown in Figure 1. Slide the next
module in place and anchor module as instructed
above. Replace the inserts into the lower module
and secure with retaining screw and washer. Make
sure that insert tabs are placed under the retaining
pins as shown in Figure 3. Repeat process until
all modules are installed.
BACKFILLING
FAILURE TO PROPERLY BACK FILL WILL
VOID WARRANTY
If sandy soil exists, line the opening with a perma-
nent barrier (such as house wrap) to restrict sand
from washing into rock.
Undisturbed Soil
Outside of Well: Backll evenly by hand on all
sides as the hole is lled in; Do not do one side at
a time. Always use 3/4” clean free-draining rock
or A6 stone completely around the well at least
12” in width to isolate the well from the earth. Fill
area to within 4” of top module. This will keep
window well movement to a minimum during cold
weather freeze/thaw conditions and settling soil.
Do not use expansive soils, frozen soils, material
that has debris, or organic material.
Inside of Well: Place the free-draining rock in the
bottom of the well to within 1” of the window sill. If
a perimeter drainage system exists, it is best to tie
the well drainage into this system by running a pipe
extension up from the drain line to the base of the
well. Make sure that the free draining rock lls the
space directly under the deepest well module to
the bottom of the excavation. Do not settle material
around the well with water.
