Follow the precautions below for optimal
product performance and to reduce the risk of
property damage, personal injury, and/or death.
WARNING
: Always wear safety glasses, a dust mask,
and ear protection when installing.
CAUTION
: The fiberglass hull below the transducer
must be SOLID. The transducer will not transmit
through coring material such as foam or balsa wood.
CAUTION
: Do not install in the engine compartment
or other hot place. The transducer may fail if the
temperature of the liquid in the tank exceeds 60° C
(140° F).
CAUTION
: Always operate the transducer in liquid.
Operating in air will allow the transducer to overheat
resulting in failure.
CAUTION
: Never pull, carry, or hold the transducer by
the cable. This may sever internal connections.
CAUTION
: Never use solvents. Cleaner, fuel, sealant,
paint, and other products may contain solvents that can
damage plastic parts, especially the transducer’s face.
IMPORTANT
: Please read the instructions
completely before proceeding with the installation.
These instructions supersede any other instructions in
your instrument manual if they differ.

Assembling the Transducer
1. Remove the paper backing from the adhesive side of the gasket.
With the adhesive side facing the plate, align the holes and
edges of the gasket with the under side of the plate (Figure 2).
Press the gasket firmly into place.
2. Thread the cable through the cable hole in the gasket and plate.
3. Rest the plate on the transducer with the gasket side down and
align the mounting holes. Fasten the plate to the transducer.
Use four of the hex-head bolts and lock washers supplied.
Tighten using a torque wrench with a force not exceeding
85 in-lb.
Do not over tighten the bolts
.
4. Thread the cable under the handle as seen in the drawing above.
