Option B: Mounting Column (model 30-831) 1. E xcavate a trench from the valve to the column location and then, pull a set of colored wires from the valve area to the mounting column location (one pair for each valve). Each pair should consist of one white wire, and one red or colored wire, preferably of differing colors. Each pair should be taped and marked separately at both ends, so that the wires do not get cross-connected (see ). 2. I nsert the pairs of wires through the bottom of the mounting column and push the wires up through the column until at least 6” (15 cm) of wire extends from the top of the mounting column (see ). 3. I nstall the mounting column, setting the curved bottom of the mounting column in an 8” x 8” x 6” (20 x 20 x 15 cm) frame and pour in the 90 lb (40 kg) sack of cement (see detailed illustration).
