4.
Keep the deck cable plugged into the Sonar Head Unit, or use dummy plugs to
keep the connectors from exposure to the salt atmosphere. Remember to put a
thin film of silicone grease, such as Dow-Corning 4, on the rubber portion of the
underwater connector every time the Sonar Head Unit is disconnected. Avoid
getting too much grease on the metal pins of the connector; a very light coating is
sufficient.
5.
Check that all of the screws on the Sonar Head Unit are tight.
4.2.2 Weekly Maintenance Checklist
Perform the following maintenance steps at the end of each week’s operation:
1.
Turn off the power to the TPU and to the SonarPro Workstation.
2.
Check all cables for abrasion and damage. If any wear spots are noticed, clean
them with fresh water, dry them, and wrap them carefully with electrical tape,
such as Scotch #88 or #33. If there is wear or fraying in any of the cables in an
area subject to high tension, repair or replace the cable.
3.
Inspect and clean the system connectors.
4.
Inspect the Sonar Head Unit for signs of corrosion or other damage.
5.
Check the underwater connectors on the Sonar Head Unit. The contacts should be
clean and shiny. Contacts may be cleaned with a rubber pencil eraser or very fine
emery paper.
4.2.3 Long Term Maintenance Checklist
Perform the following maintenance steps at six month intervals, or more
frequently when continued long term usage is occurring.
1.
Turn off the power to the TPU and to the SonarPro Workstation.
2.
Thoroughly clean the TPU and cables. Clean the top and outside surfaces of the
TPU using a cloth dampened with fresh water. Use a small amount of detergent if
necessary. Do not let dirt and salt deposits accumulate on the TPU cabinet.
3.
Replace the AC fuses in the TPU as preventive maintenance. Fuses will
sometimes fatigue after long term use or operation.
4.
Check that all the connectors on the Sonar Head Unit are firmly seated. Make
sure that all the cables are free from cuts or abrasion.
5.
Follow the instructions in the manufacturer's manual for any necessary cleaning
and maintenance of the
SonarPro Workstation
