Safety Rules Recreational Vehicle Generator SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted in potential hazard areas of the recreational vehicle. Safety should be stressed to all operators and potential operators of this equipment.
• Adequate, unobstructed flow of cooling and ventilating air is critical for expelling toxic carbon monoxide gas and fuel vapors from the generator compartment and for proper genera- tor operation. Without sufficient cooling airflow, deadly carbon monoxide gas can accumulate and the engine/generator may quickly overheat, causing serious damage to the generator.

Section 2 – Installation Recreational Vehicle Generator LOCATION AND SUPPORT 2.1.1 GENERATOR LOCATION The most desirable location for the generator set is between the vehicle's main frame members. However, this is seldom possible. Most units must be installed on the side of the vehicle and are difficult to reinforce.
Figure 2.3 – Typical Generator Restraint GENERATOR COMPARTMENTS Whether the generator set is being installed inside a compartment specifically manufactured to house a generator or inside a compart- ment that the installer constructs, the compartment MUST meet certain specifications as outlined in the following sections: 2.2.1 COMPARTMENT SIZE Plan the compartment size carefully.

2.5.3 VAPOR WITHDRAWAL LP gas is stored in pressure tanks as a liquid. The gas systems used with these generators were designed only for vapor with- drawal type systems. Vapor withdrawal systems use the gas vapors that form above the liquid fuel in the tank. Do NOT attempt to use the generator with any liquid withdrawal type system.
Section 2 – Installation Recreational Vehicle Generator DANGER Gaseous fuel lines between the tank and the secondary regulator are under a positive pres- sure (about 11 inches water column). Gas pres- sure at the outlet side of the secondary regula- tor, however, is a negative pressure and can draw flame inside a line or fitting and cause an explosion.
• Never tee the generator engine exhaust pipe into the vehicle engine exhaust piping. This causes excessive back pressure on the generator engine. Also, water from one engine can damage the other engine. • Plan exhaust system installation carefully. Comply with all appli- cable codes, standards and regulations.
Section 2 – Installation Recreational Vehicle Generator • Route conduit so it does not interfere with generator move- ment. • If using metallic conduit, vapor seal the end of the conduit where it enters the junction box. Do this because flexible metal- lic conduit is not vaporproof along its entire length.

These generators are rated at about 100 DC amperes of cranking current. Select battery cables based on (a) cable length and (b) prevail- ing ambient temperatures. Generally, the longer the cable and the colder the weather, the larger the cable size must be, as shown in the chart.
Section 3 – Post-installation Start-up Adjustments Recreational Vehicle Generator 2.8.4 BATTERY COMPARTMENT Install the generator battery in its own, vented compartment. Place the battery compartment away from any source of heat, sparks or flame. Provide ventilation openings in the battery compartment. The minimum size of openings should be 2 square inches at the top of the compartment.
NOTE: The generator set was thoroughly tested and adjusted at the factory before shipping. No additional adjustment should be necessary. Only qualified service technicians who have been trained should perform adjustments outlined in this manual. TESTING UNDER LOAD Apply electrical loads equal to about 75 to 100 percent of the unit's rated wattage/amperage capacity.
