Generator
•
When your yacht is not connected to shore power, the generator can supply 110-volt/60-hertz power.
•
Before using the generator, read the generator operation manual for pre-start checks and break-in procedures.
•
Refer to the generator manual for starting/stopping instructions.
Important generator notes:
•
Polarity has been established in the installation of the generator. Therefore the polarity lights will not function in
this mode.
•
Fuel to run the generator is supplied from the starboard fuel tank.
•
Periodically replace the filter on the generator to make sure it remains clean and free of debris.
•
Diesel generators also have a fuel filter/water separator. Service instructions are provided on the fuel
filter/water separator.
•
The coolant mixture installed at the factory consists of equal parts of water and antifreeze (Ethylene Glycol).
•
Check the generator’s seawater strainer for leaks and/or debris before each use.
CARBON MONOXIDE POISONING HAZARD!
•
Generators are a source of dangerous carbon monoxide gas (CO). Check the
generator exhaust system for leaks BEFORE each use.
•
Read the Carbon Monoxide (CO) section of Chapter 1 in this Owner’s
Manual.
