When removing an accumulator that will be reused, or when installing a new accumulator, ensure inlet and outlet openings of unit are protected from exposure to the atmosphere. If openings are not sealed, moisture contamination will result, rendering unit inoperative. New units are supplied with caps for this purpose, and plastic sheet and elastic bands may be used on units removed from vehicles.
