Table 3-2. Battery type 3.1.
Voltmaster Engine-Driven Generators 3.1.6 LN-Series (propane/natural gas) models LN-Series generators feature a special vapor fuel carburetor with a vacuum safety shutdown and an electric solenoid fuel shutdown. LN-Series generators are derated, because the liquid propane (LP) and natural gas (NG) fuel reduces engine output slightly versus gasoline. Safety ■ Only a qualified LP or NG installer should work with LP and NG fuel lines, connections, and components.
Voltmaster Engine-Driven Generators Fuel line The incoming fuel line should be a 1-inch line. Fuel connections on the generator are 3/4-inch NPT. To protect the flexible fuel line against rupture, route the fuel line away from the engine muffler and manifold. Do not remove the cover from the solenoid valve until you are ready to make pipe connections. Before the flexible fuel connection is connected to the hard fuel pipe connections, and after all other fuel line connections have been made: 1.
Voltmaster Engine-Driven Generators 3.1.7 Standby installations Safety concerns WARNING Shock hazard. Failure to isolate generator from power utility can result in death or serious injury. When using the generator for backup power: ■ Never connect the generator output to any live home or commercial electric circuits. ■ Use a suitable power-transfer device to isolate the generator from the power utility. ■ Use a licensed electrician or electrical contractor to install the power-transfer device.
Voltmaster Engine-Driven Generators Emergency circuit isolation To address the possibility of overloading the generator, the building may be wired so emergency circuits are grouped together, rewired to a separate junction box, and connected to the generator through a manual transfer switch. The emergency circuit should be configured so it does not exceed the ampere rating of the generator. The transfer switch must have an ampere rating equal to that of the emergency circuit.
Voltmaster Engine-Driven Generators 3.1.8 Preparing for use 1. Ensure the generator is in proper working order: ■ Check the generator for damage and wear. ■ Secure all fuel and wiring connections. ■ Tighten loose screws, nuts, and bolts. ■ If applicable, ensure the starter battery is fully charged (see Section 3.3.3, page 29). If a trickle charger was used when the generator was not in use, disconnect the charger. 2. Read tags and labels, and follow all directions.
Voltmaster Engine-Driven Generators 3.2 Operating the generator 3.2.1 Models LR50EL and LR60EL Model LR50EL and LR60EL generators feature electric-start engines with auxiliary recoil starters. To start the engine on these models if a battery is not available, move the red or black lever near the fuel pump to the up position. If a 12-volt battery is installed, the lever must be in the down position at all times. 3.2.
Voltmaster Engine-Driven Generators 3.2.3 Air in fuel line For diesel models, air pockets in the fuel line will cause difficulty in starting and operating the generator. ■ Before starting, pump the fuel lever 20 times or more. ■ Do not allow the generator to run out of fuel or to the bottom of the fuel tank. 3.2.4 Electrical loads Ratings Complete ratings for the generator are listed on the generator serial number tag, which is attached to the generator housing.
Voltmaster Engine-Driven Generators D-Series diesel models CAUTION Operating a diesel generator without the proper load will permanently damage the engine. Always operate the diesel engine under load, using at least 25% of its rated capacity. Diesel models require a load of at least 25% of the generator’s rated output. Operating a diesel generator with insufficient load (referred to as “wet stacking”) will irreparably damage the engine and void the warranty.
Voltmaster Engine-Driven Generators Plugs and connected equipment Use only 3-prong grounded plugs, 3-wire extension cords, and 3-wire or double-insulated power tools with the generator. Full-power switch Some models are equipped with a switch that allows selection of 120-volt power only or both 120- and 240-volt power. ■ ■ ■ When using the generator to power only 120-volt equipment, put the full-power switch in the 120V position.
