Insert the expansion anchors into the holes, with the slotted end down and then, insert the setting
tool provided, small end first, into the anchor and expand the anchor by hitting the large end of
the setting tool with several sharp hammer blows.

3.3 Installing the Weak Link and Extension Cable
The extension cable is used to cover the distance between the two points. A length of plastic
coated 1/16-inch aircraft cable is supplied for this purpose. The cable has two loops which are
shipped loosely held by two cable clamps. When the Transducer enclosure has been installed and
the remote anchoring station, attach the extension cable to the anchor station and tighten the two
cable clamps. Using the snap-swivel hooks the ends of the weak link, hook the weak link onto
the extension cable loop and on to the end loop of the cable wound on the drum in the enclosure.
Adjust the extension cable length by pulling cable through the two cable clamps until the wire is
tight and the wire tension is taken by the drum. Connect the readout cable to the readout box.
Pull approximately four inches of cable off the drum so that there is some movement of the
transducer as revealed by a change of reading on the readout box. Tighten the two extension
cable clamps and the two clamps on the weak link assembly.
3.4 Cable Installation
The cable should be routed and protected in such a way to minimize the possibility of damage
due to moving equipment, debris or other causes. Cables can be spliced to lengthen them,
without affecting gauge readings. Always waterproof the splice completely, preferably using an
epoxy-based splice available from the factory.
