hanger bolts to secure the bracket on the riser. Loosen the cord grip in the top of the riser cap and push
the probe cable up through the cord grip and replace the riser cap and tighten the probe cable cord grip.
Insert a piece of ½-inch conduit or ducting into the loosened conduit clamps in the battery pack support
bracket. The conduit can be positioned below the manhole cover from 1 to 6 inches, as required for best
signal reception. Place a mark on the conduit above the top clamp. Remove the conduit to a non-
hazardous location and cut off the excess length. Push the conduit down through the two clamps until the
top clamp is below the mark on the conduit and tighten the two clamps.
