For Existing Pavements:
2. To install base cans, begin by core drilling (typically 12"-14” diameter, the depth will be
per the terrain and/or suggestion of the civil engineer/contractor) holes in the locations
specified by the project engineer. Saw cuts should then be made to allow room for the
fixture power cables (typically 3" deep x 1/2" wide). Saw cuts are typically made in line
with the centers of the conduit holes.
3. Prepare the drainage system specified by the design engineer. (see figure 1 on page 7
and notes)
4. Install the rubber grommets in each of the side holes.
5. Install the base can drain fittings provided (pictured below) into each base can drain
hole. Run 1-1/2" size pipe, schedule 40 PVC, into the fittings of the base can. Pipe length
should be cut so the pipe, when positioned over the drain, extends approximately 3" to
4" into the drain rock.

6. Use of mounting jig is recommended for proper alignment of base cans. First, place the
plywood cover on the base can, and then mount the mounting jig to the base can with
the two bolts that fit into the base can bolt holes.
