DO NOT modify that a competent, qualified technician installed the generator into the generator or use it for any application other than for what it a recreational vehicle.
General Information 120/240 VAC loads — one load with a maximum total watt- NOTE age requirement equal to the generator’s rated power output, Some installations using a “shared” fuel tank may have a gen- and 240V across the generator output terminals; or two sepa- erator fuel pickup tube that is shorter than the vehicle engine’s rate loads, each with a maximum total wattage requirement pickup tube.
Operation EVAPORATIVE EMISSIONS Figure 2.1 – Typical Control Panel INFORMATION This generator is subject to evaporative emission standards which have been implemented by the California Air Resource Board (CARB) and the Environmental Protection Agency (EPA). If this generator is offered for sale in the state of California, it must be covered by a CARB evaporative Executive Order.
Operation 2.1.4 DIAGNOSTICS 2.3.2 PRECHOKE If the generator shuts down due to a fault, the indicator will flash a The choke system also has a temperature-sensitive metal strip that code to identify the problem. adjusts choke valve angle according to ambient temperatures (i.e., in cold ambient temperatures, choke valve closes more).
Operation 2.4.5 ENGINE EXHAUST GAS NOTE: If starting from the generator control panel, turn OFF loads Before starting the generator engine, be sure there is no way for by setting the generator’s main circuit breaker to the OFF (or exhaust gases to enter the vehicle interior and endanger people or open) position.

For light bulbs, The Controller Circuit Board houses a field boost diode and resistor simply note the wattage rating of the bulb. that are not part of the automatic choke circuit.
Maintenance CHANGING THE ENGINE OIL 2.8.5 OPERATION IN HIGH GRASS OR BRUSH AND/OR OIL FILTER Never operate the generator while the vehicle is parked over high grass, weeds, brush, Hot oil may cause burns. Allow engine to leaves or any other combustible substance. cool before draining oil.
Maintenance CHECKING THE ENGINE 10. Remove the dipstick, valve cover plug and add new oil (see “Engine Oil Requirements”) to engine. DO NOT FILL ABOVE SPARK PLUG THE “FULL” MARK. Reset the spark plug gap or replace the spark plugs as necessary. 11.
Maintenance CLEAN SPARK ARRESTOR The engine exhaust muffler has a spark arrestor screen. Inspect and Do NOT use a forceful spray of water to clean the screen every 200 hours of operation or once each year, clean the generator. Water will enter the gen- whichever comes first.

Make sure to identify the MODEL Check the tag on the engine for oil viscosity and classification.
Safety Rules DANGER: For fire safety, installation of a generator into a recreational vehicle must comply strictly with article 551, NFPA 70; ANSI C1-1975; AND, ANSI A119.2-1975/NFPA 501C “Standard for Recreational Vehicles” (Part 3, “Installation of Electrical Systems”). In addition, installation must comply with the man- ufacturer’s instructions and recommendations.

General Information PURPOSE AND SCOPE OF THE EQUIPMENT DESCRIPTION Instructions and information in this section pertain to air-cooled INSTALLATION INSTRUCTIONS generators. These generators are designed specifically for install- These Installation Instructions have been prepared especially for ing in recreational vehicles. They operate 120-volt, single-phase, the purpose of familiarizing installers and owners of the applicable 60-Hertz, AC electrical loads.
Installation Figure 1.3 - Connection for 120/240 Volts • The location must provide sufficient room to allow minimum clearances as outlined in "Generator Compartments". If sound insulation is to be used on the compartment walls and ceiling, the minimum recommended applies to the space between the generator and such insulation.
