Kohler 3.5CFZ, 4CZ, 5CFZ, 6.5CZ installation manual Closed/Heat Exchanger, Seawater Strainer

A seawater strainer of sufficient capacity should be mounted to the seacock or permanent structure at a point not higher than the seawater pump. The strainer should be accessible for servicing. See Figure 6-13 for a typical installation. The optional Kohler seawater strainer is threaded for 1/2 NPT fittings.

NOTE

Some seawater strainers include seacock and intake thru-hull strainer.

Waterlines from the seacock to the engine-driven seawater pump can be copper tubing or flexible hose. A flexible section of hose is used for the actual connection to the seawater pump to allow vibrational motion of the generator set during operation. The hose should have an inside diameter of 3/4 in. (19 mm). Copper line should be supported within 4 in. (102 mm) of its connection to the flexible section.

NOTE

A 5/8 in. (16 mm) waterline hose can be substituted for the recommended 3/4 in. waterline hose.

Piping should be kept straight and as short as possible. See Figure 6-14 for the seawater connection to the seawater pump inlet. The seawater outlet is combined with engine exhaust gases. (On sound shielded units, a small section of molded hose is required for the seawater inlet connection.)

Closed/Heat Exchanger

A closed, heat exchanger cooling system, the best alternative for most applications especially if craft is to be operated in salt waters or waters with high silt content, is provided as part of the generator set.

Service accessibility must be provided for the heat exchanger pressure cap. See Figure 6-15.
