RAW WATER SUPPLY
For raw water supply the following installation materials
are required: -a skin fitting - a sea cock - a water strainer -
hoses and clamps. In order to keep the suction resistance
in the line at a minimum, the sea water intake system (i.e.
sea cock, tru-hull fitting, inlet filter, etc.) must have the
following inner diameter at least:
Model
Minimum inner diameter
M-SQ7
3/4" (19 mm)
The suction hose should be kept as short as possible.
Raw water plumbing should avoid bends as much as
possible.
Restriction of raw water flow, caused by kinked hoses,
undersized pipes or connections, will reduce the engine
cooling capability. This is the main cause for overheating
of an engine.
After running the generating set for the first time, check the
coolant flow rate using a stopwatch and by holding a pail
of a known volume under the wet-exhaust outlet. The flow
rate should be according to the data in the users manual.
