24. Examine the pressure relief plug and O-rings. Clean or replace as necessary.
25. Verify that the voltage between contacts 1 and 2 on the bulkhead connector is
correct.
2.3 Regular maintenance
Alkaline battery packs require very little maintenance. Protect the unit from impact, flush
with fresh water after each deployment, and store it with the dummy connectors to extend
the life of this unit. Make sure that the O-rings on the end flange and the pressure relief
valve are pristine. Use the manufacturer-supplied Dow-Corning DC-111 to lubricate new
O-rings.
Pre-deployment maintenance
Inspect the pressure housing for any damage. Deep cuts or scratches weaken the
housing and reduce the depth at which the unit can safely operate. In addition, make sure
that—
• the connector is firmly seated and the lock collar is tight.
• the anode is not too corroded.
• the pressure relief valve is seated correctly.
