Assembly Procedure

1. Clean the heat exchanger and inspect the heat exchanger.

2. Examine the heat exchanger for signs of leakage, cracks, corrosion, damaged tubes or hose connections. If the tube bundle is damaged, the tube bundle should be replaced. Check the sealing face of the end caps. If there is corrosion on the body of the heat exchanger in the area of O-ring seals, replace the body of the heat exchanger.

3. Clean the components of the heat exchanger in an approved cleaning fluid.

4. If there is a restriction in the tubes of the tube bundle, the tubes can be cleaned with a 4 mm (0.157 inch) rod. Push the rod carefully in the opposite direction to the flow of sea water. Continue this operation until all of the tubes are clean.
