ducer faces on the Workhorse if it will be exposed to sun-
light.
• Do not expose the I/O connector to prolonged sunlight. The
plastic may become brittle. Cover the connector on the
Workhorse if it will be exposed to sunlight.
• Do not store the ADCP in temperatures over 75 degrees C.
The urethane faces may be damaged. Check the tempera-
ture indicator inside the shipping case. It changes color if the
temperature limit is exceeded.
• Do not scratch or damage the O-ring surfaces or grooves. If
scratches or damage exists, they may provide a leakage
path and cause the ADCP to flood. Do not risk a deploy-
ment with damaged O-ring surfaces.
• Do not lift or support a WorkHorse by the external I/O cable.
The connector or cable will break.
• Read the
Maintenance guide
assembly. Make sure the housing assembly O-rings stay in
their groove when you re-assemble the WorkHorse. Tighten
the hardware as specified. Loose, missing, stripped hard-
ware, or damaged O-rings can cause the WorkHorse
transducer to flood.
• Place a light amount of DC-111 lubricant on the end-cap
connector pins (rubber portion only). This will make it eas-
ier to connect or remove the I/O cable and dummy plug.
• Do not connect or disconnect the I/O cable with power ap-
plied. An exception to this is the external battery case. The
external battery case connector is always "hot" when batter-
ies are installed. When you connect the cable with power
applied, you may see a small spark. The connector pins
may become pitted and worn.
• The WorkHorse I/O cable is wet mate-able, not under water
mate-able.
• Align the compass whenever the battery pack or recorder
module is replaced, or when any ferrous metals are relocated
inside or around the WorkHorse housing. Ferro-magnetic
materials affect the compass.
