Care and Servicing
Cleaning the Gauge
After each submersion, and while the instrument is still
assembled, wash the unit in fresh water and allow to dry
To maintain the water-tight integrity of the assembly : the
Gauge should be disassembled after every submersion, and
the O-Rings should be replaced with new
Clean the O-Ring grooves, and ensure that there are no
particles remaining -
a mild detergent may be necessary to remove grease from
the O-Ring grooves
Care should be taken not to allow water into the instrument
body whilst cleaning
Do not use solvents for cleaning
Do not use any abrasive cleaner
Use of O-Rings
When reassembling before a submersion: always replace both
O-Rings with new, first ensuring that they are lubricated with
Silicone grease
To avoid the risk of a leak: prevent accidental re-use by
destroying all used O-Rings after each submersion
Data-link connector
Always apply a coating of Silicone grease to the pins of the
data-link connector before insertion into the socket on the
Gauge
If the Gauge is to be stored without the cable assembly
connected, it is essential that the Blanking plug is inserted in
the socket instead
The pins of the Blanking Plug should also be lubricated with
Silicone grease
