1. Lift the enclosure with a lifting appararatus rated in excess of 500 lbs. Confi gure
the lifting arrangement so the distance from the top of the cabinet to the lift ring
or hook is at least twice the distance between the lifting ears (Fig. 3-2).
2. Position the enclosure above the concrete pad, and slowly lower it into position
over the pad’s 3/8" (or 1/2") anchor or J-bolts. Use a 25-year vapor barrier
between the concrete and enclosure base to inhibit moisture ingress, and to
prevent possible corrosion caused by metal to concrete contact. The vapor
barrier material (such as 30 lb. felt, neoprene pond liner, or heavy grade tar
paper) should initially extend at least 6" in all directions around the perimeter of
the enclosure. After the enclosure is in place, the material should be cut closer to
the enclosure, using the appropriate knife or cutting tool.
3. Secure the enclosure using stainless or galvanized fl at washers, lock washers,
and 3/8" (or 1/2") nuts at each mounting bolt. Torque mounting hardware in
accordance with the manufacturer's recommendation.
4. Make a small cutout in the vapor barrier material directly under the pad shear
sensor, Apply silicone glue to the concrete pad (in the cutout section) and set the
pad shear magnet into the glue (potted side down). Let the glue set 12-24 hours.

To prevent damage to the enclosure, it must be mounted fl ush to a completely fl at surface. If the
concrete pad is uneven or has bumps, cracks or other imperfections, the installer is responsible for
correcting these defects prior to installing the enclosure.
