Precast Pad Installation
Outback recommends using precast polymer mounting pads. These pads are designed for proper cabinet
support and ease of installation. Drilling areas for openings are indicated for coaxial and service sweeps, and
pre-installed threaded inserts for enclosure attachment.
Site Considerations
•
The site must be planned so the enclosure receives good air flow. In areas of extreme heat, position the
enclosure so that it will be shaded from the afternoon sun. In areas of prevailing winds, it is best that the
enclosure be located so that the sides of the cabinet face the winds instead of the doors. This will greatly
reduce the buildup of sand or snow against the enclosure’s air vents.
•
In areas of potential flooding, the site must be located above the 100-year flood plain.
•
The enclosure must be placed where it will be free of obstructions, allowing easy access to the doors for
service or equipment access. For ventilation and maintenance near other solid structures, allow a minimum
space of 36" (91 cm) between the front and rear of the enclosure, as well as on the sides.
•
Place the enclosure well away from sources of forced water, such as underground sprinkler systems and direct
roadway splash.
•
The concrete pad drawing provided in this manual contains all of the required mounting details, including
electrical service and cable plant entrances.
•
For ease of installation, lightweight polymer concrete pads are available from Outback for the OBE-3-FT
enclosure.
•
The vapor barrier material (such as 30 lb. felt, neoprene pond liner, or heavy grade tar paper) must initially
extend at least 6" (15 cm) in all directions around the perimeter of the enclosure and then be trimmed closer
to the enclosure.
•
Contact local utilities or cable/piping locator services to ensure that the installation does not interfere with
existing cables or piping.
