PROBLEM

The metal pipe in existing lines group-cooling, 183-9195, which is used on 3500B petroleum genset packages is different than the metals used in jacket coolers. The use of dissimilar metals may cause jacket cooler failure when seawater is used as the coolant media. New line group-cooling, 216-8576 uses copper nickel piping to agree with the jacket cooler metals.

ACTION REQUIRED

Isolate package cooling system. Remove existing line group. Flush pipes and fittings of new line group to assure they are free of dirt and debris. Install new line group. Test for leaks. Re-energize package cooling system. NOTE: When performing welding on package, welding system ground conductor must be as near as possible to the welding location. Always connect the welding ground conductor on the same package side where the welding will occur to avoid current flow across engine and generator bearings. Welding across engine and generator bearings may cause significant bearing damage. Never weld across the package center line.
