MAINTENANCE

The 8242XS requires minimal maintenance. Pre-deployment preparations and checks, and post-
deployment cleaning will fulfill most of the maintenance requirements. The important tasks are battery
replacement, 'O' ring care and maintenance, and general cleaning, inspection, and lubrication of
operational elements.

Housing and Release Preparation and Care

To access the electronics assembly or mechanical assemblies, remove the five sets of titanium hardware
holding the upper and clevis End Caps in place, as shown in

The 8242XS releases are shipped with 12 PSIA (-2.5 PSIG) of dry nitrogen, which reduces moisture in the
housing and helps to seat the O-Rings. Equalization of pressure by removal of the purge port plug will be
necessary to gain entry into the instrument.

WARNING!

If the underwater unit has been deployed, there is the

possibility of leakage and internal pressurization of the housing. If the
housing is pressurized, be sure to exercise extreme caution when
relieving the pressure. The resulting violent motion of some parts can
result in serious personal injury.

NOTE:

In some releases the cable from the electronics to the transducer

is short (12 inches (30 cm.)). To prevent parting the cable, always remove
the top (transducer) end cap first, and disconnect the transducer from
the electronics.

WARNING!

High voltage is present at this connector when the unit

transmits reply bursts.
