attachment to the vessel. The connector on the rear of the Transducer Module is capable of a wet mating
and un-mating. If necessary, this allows the Transducer Module to be installed and removed from the vessel
by a diver underwater, rather than dry docking or hauling the vessel. Here are the primary steps for installing
the Transducer Module into a pre-installed fairing mount.
1. Unpack the Transducer Module. Ensure that there is no debris caught in the connector pins.
2. Dab a small amount of silicon o-ring grease on the rubber sleeve of each connector pin (on the
Transducer Module). Be sure not to get any grease on the pins themselves.
3. If the installation is done underwater, a blank connector cover should have been used on the
Transducer Module Connection Cable's wet end connector. Remove the blank connector cover from
the cable.

4. Connect the Transducer Module Connection Cable to Transducer Module. Be sure that the connector
is fully connected. The black rubber on the cable and the Transducer Module connectors should be
flush with each other.
5. Hand tighten the red connector locking collar on the cable and Transducer Module.

6. Connect the Transducer Module in to your installation mount. You should use all 12 bolts if possible.
Bolts are not included.
When installing the Transducer Module into your mount, the orientation of the Transducer Module is very
important. There is a protrusion on the black urethane face on the front of the unit that should be at the
12 o'clock position. The connector on the rear of the Transducer Module should also be at the 12 o'clock
position. As with any piece of bolted hardware, the use of washers and lock washers is recommended.
Important
Do not put caulking (such as Sikaflex) around the Transducer Module. It is important that water
be able to flow through the small slits in the installation collar in order to help with system cooling.
