Caring for the H-ADCP System

This section contains a list of items you should be aware of every time you handle, use, or deploy your
H-ADCP. Please refer to this list often.

General Handling Guidelines

•
Never set the transducer on a hard or rough surface. The urethane faces may be damaged.
•
Always remove the retaining strap on the underwater-connect cable and dummy plug when dis-
connecting them. Failure to do so will break the retainer strap.
•
Do not apply any upward force on the end-cap connector as the I/O cable is being disconnected.
Stressing the connector may cause the H-ADCP to flood. Read the Installation section for
details on disconnecting the I/O cable.
• Do not expose the transducer faces to prolonged sunlight. The urethane faces may develop
cracks. Cover the transducer faces on the H-ADCP if it will be exposed to sunlight.
• Do not expose the I/O connector to prolonged sunlight. The plastic may become brittle. Cov-
er the connector on the H-ADCP if it will be exposed to sunlight.
• Do not store the H-ADCP in temperatures over 60 degrees C. The urethane faces may be
damaged.
• Vent the system before opening by loosening the hardware on the housing. If the H-ADCP
flooded, there may be gas under pressure inside the housing.
• 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 H-ADCP to flood. Do not risk a deployment
with damaged O-ring surfaces.
• Do not lift or support an H-ADCP by the external I/O cable. The connector or cable will
break.
•
The 300 kHz NB H-ADCP should only be lifted by holding onto the transducer mounting plate.
Do not lift by holding onto the housing, end-cap, or beams.
rious damage to the H-ADCP or personnel lifting the unit.

Assembly Guidelines

•
Read the Maintenance section for details on H-ADCP re-assembly. Make sure the housing assem-
bly O-ring stays in the groove when you re-assemble the H-ADCP. Tighten the hardware as speci-
fied. Loose, missing, stripped hardware, or a damaged O-ring can cause the H-ADCP
transducer to flood.
•
Use light amounts of silicone lubricant (such as 3M
4678-4930-3) on both the male pins and female socket to help seat the cable connectors. Wipe off
excessive silicone spray from the metal portions of the pins. Regular lubrication is required:
Apply dry type silicone lubricant prior to each connection.
•
Do not connect or disconnect the I/O cable with power applied. When you connect the cable with
power applied, you may see a small spark. The connector pins may become pitted and
worn.
• The H-ADCP I/O cable may be connected while slightly wet; do not connect under water.
