Actual fuel consumption will vary depending on operating conditions. Engine Block Lubrication System • Four cycle, 3 cylinder, liquid cooled, naturally aspirated, overhead valve diesel. • Full ow, spin-on oil lter with bypass. • Swirl combustion chambers improve fuel efciency and reduce smoke. • 3.1 qt (3 ltr) oil capacity for better lubrication and 200 hour oil change intervals. • Glow plugs for quick cold starting. • Oil drain for quick, clean oil changes. • Freshwater cooling. • Closed crankcase vent system traps oil vapor and keeps engine room clean. Cooling System • Heat exchanger or keel cooled. • One-piece heat exchanger, expansion tank and liquid cooled exhaust manifold. Fewer troublesome hoses and gaskets. Cast iron to resist corrosion and electrolysis. • 12 volt starter motor and battery charging alternator with belt guard. • DC system uses reliable relays instead of an unrepairable printed circuit board. • Heat exchanger cooling is standard. Cupro-nickel, tube-type heat exchanger has removable ends for easy cleaning. Rubber impeller, seawater pump of bronze and stainless steel is gear driven; no belt. • Standard panel: Remote mount S-1B has hour meter, stop-start switch with run light and preheat switch. • Fuel system is self-venting. • 20 foot (6m) plug-in panel harness lets you mount your panel anywhere onboard. Better than inaccessible unit mount panels that are prone to vibration problems. Fuel System • Injection pump with 5% mechanical governor for close AC frequency control. • Pintle injectors with replaceable tips. • Mechanical lift pump with hand primer. No electric pump to fail. • Large spin-on fuel lter. • Flexible fuel lines routed to fuel manifold. • Stop solenoid acts directly on the fuel rack eliminating linkage problems. • Meets US EPA Tier III emission standards at date of manufacture. • Washable air cleaner. • Cast aluminum intake manifold with Sound Maze air intake reduces intake noise. • Cast iron, wet exhaust elbow for safety. • Expandable to six panels up to 110 feet from the set. • Low oil pressure, high coolant temp and high exhaust temp safety shutdowns standard. • Northern Lights, direct coupled, four pole, revolving eld, four lead reconnectable generator with Class “H” insulation and prelubricated bearing. Conservative heat rise rating: 95°C/50°C ambient . • External automatic voltage regulator gives you ±5% voltage regulation. AVR powered by dedicated AC winding for improved motor starting. AVR circuit breaker. • 30 amp mainline circuit breaker protects generator from AC overloads and shorts. www.northern-lights.com Northern Lights, Inc. • 4420 14th Ave. NW., • Seattle WA 98107 Tel: 206-789-3880 • 1-800-762-0165 • Fax: 206-782-5455 Information and dimensions subject to change without notice.
