PRIMEPACT 66G and 66LP Recreational Vehicle Generators

NOTE: ◆ 2.3.2 PRECHOKE

If this generator has been reconnected for dual voltage AC output (120/240 volts), you can install line breakers having an amperage rating that is different than that stated above. The replacement line breakers consist of two separate breakers with a connecting piece between the breaker handles (so that both breakers will operate at the same time). If the unit is reconnected for dual voltage, it is no longer RVIA listed.

The choke system also has a temperature-sensitive metal strip that adjusts choke valve angle according to ambient temperatures (i.e., in cold ambient tem- peratures, choke valve closes more). Once the engine starts, an element heats the temperature-sensitive strip to a normal operating condition, opening the choke valve. This may take about three minutes in cooler weather.

2.2OPTIONAL REMOTE

START/STOP PANEL

A remote mounted Start/Stop Panel (Figure 2.2) is available that allows you to start and stop the gener- ator engine conveniently from inside the vehicle. The remote panel includes a Start/Stop switch, hourme- ter, generator run lamp and a wire harness.

2.3AUTOMATIC CHOKE

This engine is equipped with an automatic choke that consists of two main components: a choke solenoid and prechoke.

2.4BEFORE STARTING THE ENGINE

NOTE:

Instructions and information in this manual assume the generator has been properly installed, connected, serviced, tested and adjusted by a qualified installation technician or installation contractor.

◆2.4.1 INSTALLATION

Generator installation must have been properly com- pleted so it complies with all applicable codes, stan- dards and regulations and with the manufacturer's recommendations.

◆2.4.2 ENGINE LUBRICATION

Have the engine crankcase properly serviced with the recommended oil before starting. Refer to Section

1.6.3(Page 6) and Sections 3.1 and 3.2 (Page 11) for oil servicing procedures and recommendations.

Any attempt to crank or start the engine before you have properly serviced it with the recom- mended oil may result in an engine failure.

◆2.3.1 CHOKE SOLENOID

During engine cranking (Start/Stop switch at START), a solid-state choke module signals the choke solenoid to activate and cycle (choke on/choke off) until the engine starts. The choke solenoid thus opens and closes the carburetor choke valve only when the engine is cranking. When the engine starts, the choke stops cycling.

◆2.4.3 FUEL SUPPLY

The engine must have an adequate supply of proper fuel to operate. Before starting it, check that sufficient fuel is available.

NOTE:

Depending on the installation, the generator may have either a separate fuel tank, or it may “share” the vehicle engine’s fuel tank.

◆ 2.4.4 COOLING AND VENTILATING AIR

Air inlet and outlet openings in the generator com- partment must be open and unobstructed for contin- ued proper operation. Without sufficient cooling and ventilating airflow, the engine/generator quickly over- heats, which causes it to shut down and may damage the generator.
