Operation 0000.0 Connection Plugs 008090 120 VAC, 20 Amp, Duplex Receptacle This is a 120 Volt outlet protected against overload by a 20 Amp push-to-reset circuit breaker. Use each socket to power 120 Volt AC, single phase, 60 Hz electrical loads requiring up to a combined 2400 watts (2.4 kW) or 20 Amps of current. Use only high quality, well-insulated, 3wire grounded cord sets rated for 125 Volts at 20 Amps (or greater). 000424 120 VAC, 30 Amp Receptacle Use a NEMA L5-30 plug with this receptacle (rotate to lock/unlock). Connect a suitable 4-wire grounded cord set to the plug and to the desired load. The cord set should be rated for 250 Volts AC at 30 Amps (or greater). Use this receptacle to operate 120 Volt AC, 60 Hz, single phase loads requiring up to 3600 watts (3.6 kW) of power at 30 Amps. The outlet is protected by a 30 Amp singlepole circuit breaker. CO PROTECT 000844 Carbon Monoxide (CO) Detection and Shut-off System (if equipped) The CO PROTECT module monitors for the accumulation of poisonous CO gas found in engine exhaust when the generator is running. If CO PROTECT detects increasing levels of CO gas, it automatically shuts off the engine. CO PROTECT only monitors when the engine is running. Generators are intended to be used outdoors, far from occupied buildings and the exhaust pointed away from personnel and buildings. However, if misused and operated in a location that results in the accumulation of CO, like a house or even a garage with partially opened door, CO PROTECT shuts off the engine, notifies the user of what has happened and directs the user to read the instruction action label for steps to take. CO PROTECT is not a substitute for an indoor carbon monoxide alarm. As the user approaches the generator to investigate a shut-off, a blinking RED light in the CO PROTECT badge on the side of the generator provides notification that the generator was shut off due to an accumulating CO hazard. The RED light will blink for at least five minutes after a CO shut-off. Move the generator to an open, outdoor area and point the exhaust away from people and occupied buildings. Once relocated to a safe area, the generator can be restarted and the proper electrical connections made to supply electrical power. The RED light will stop blinking automatically upon engine re-start. Introduce fresh air and ventilate the location where the generator had shut down. If a CO PROTECT system fault has occurred and no longer provides protection, the portable generator is shut off automatically and the YELLOW light will blink for at least five minutes in the CO PROTECT badge to notify the user of the fault. The CO PROTECT module can only be diagnosed and repaired by a trained technician at the dealer. The generator can be re-started, but may continue to shut-off. 10 Owner's Manual for Portable Generator
