Heat exchanger, pressure testing

Heat exchanger removed

Special tools: 3849613, 885533, 885538

1. Install plugs 885533 and 885538 on the heat exchanger’s sea water unions on the cover (1).

Connect pressure test equipment 885531 to plug 885533.

Pump the pressure up to 150 kPa. Leave the equipment under pressure to ensure that the heat exchanger and its O-rings seal correctly.

IMPORTANT! If the pressure falls, the heat exchanger connection must be checked with leak testing compound (such as soapy water) to determine where the leakage comes from.

2. If the pressure falls, although you have determined that the connections are tight, the heat exchanger must be changed.
