Need help?Do you have a question about the Westerbeke 12.0KW-50Hz BTDC and is the answer not in the manual?
Read safety manual carefully. Follow fundamental rules and precautions. Know dangerous conditions.
Avoid touching AC connections while engine is running or connected to shore power. Lethal voltage present.
Do not touch hot engine parts or exhaust system. Running engine gets very hot.
Prevent flash fires. Avoid flames/sparks near fuel sources. Be aware diesel fuel will burn.
Avoid fuel vapor explosions. Keep hatches closed when fueling. Ventilate cabin after fueling.
Disconnect battery cables before servicing. Ensure personnel are clear of engine before starting.
Avoid flames near battery. Lead acid batteries emit hydrogen, an explosive gas.
Carbon monoxide (CO) is a deadly gas. Ensure adequate ventilation. Install CO detector.
Rotating parts can cause injury or death. Do not service engine while running.
High noise levels can cause hearing loss. Never operate engine without muffler installed.
Read operator's manual carefully for critical information and safety procedures.
Comply with ABYC standards, USCG, and NFPA for engine installations.
Comply with strict federal regulations, ABYC guidelines, and safety codes for marine environments.
Install siphon-break in raw water hose if exhaust elbow is below waterline. Requires periodic inspection.
Exhaust hose must be certified for marine use. System must prevent water entry.
