Section 3 – Post-Installation Start-up Adjustments

Recreational Vehicle Generator

3.1 POST INSTALLATION TESTS

The air-cooled generator set was factory tested and adjusted. It should not be required to adjust the unit any further except under special circumstances.

Do not make any unnecessary adjustments. Factory settings are correct for most applica- tions. When making adjustments, however, be careful to avoid overspeeding the engine.

3.2 BEFORE INITIAL START-UP

Before starting, complete the following:

1.Check the engine crankcase oil level and, if nec- essary, fill to the dipstick “FULL” mark (cross- hatched area) with the recommended oil. Do not fill above the FULL mark.

2.Check the fuel supply. Gas fuel lines must have been properly purged and leak tested in accor- dance with applicable fuel codes. All fuel shutoff valves in the fuel supply lines must be open.

DANGER

3.Let the engine warm up for about five minutes to allow internal temperatures to stabilize.

4.Carefully inspect the engine/generator for fuel, oil and exhaust system leaks. Before proceeding to the next step, correct any leakage immediately.

5.When all tests and adjustments at no-load are completed, apply electrical loads and check for proper operation under load (see "Testing Under Load"). Run the unit at least 30 minutes with loads applied.

6.Turn off all electrical loads by setting the gener- ator’s main circuit breakers to their “OFF” (or OPEN) position.

7.Let the unit run at no-load for a few minutes to stabilize internal engine/generator temperatures. Then, shut down the engine.

NOTE:

The generator set was thoroughly tested and adjusted at the factory before shipping. No addi- tional adjustment should be necessary. Only quali- fied service technicians who have been trained should perform adjustments outlined in this manual.

If a liquid propane (LP) gas fuel system has been installed, it must be properly tested for leaks before operating the system in compliance with ANSI A119.2/NFPA 501C. No leakage is permit- ted. Be sure that no gasoline fuel vapors enter the vehicle interior.

3.3 INITIAL START

When absolutely certain that the unit has been prop- erly installed and prepared for use, start the engine as follows:

1.Turn off all electrical loads. Do this by setting the generator’s main circuit breakers to their “OFF” (or OPEN) position.

2.Refer to Part I, “Starting the Generator”, for cranking and starting instructions. The engine may require more cranking for initial starting since the fuel lines have to be primed (use of the primer switch will shorten this time).

3.4 TESTING UNDER LOAD

Apply electrical loads equal to about 75 to 100 per- cent of the unit's rated wattage/amperage capacity.

Let the unit run at least 30 minutes with load applied. During this part of the test, check that the unit is not running excessively hot and that adequate cooling airflow is available. Do not allow the unit to overheat during prolonged operation.

NOTE:

The generator engine is equipped with a high tem- perature switch. The switch has normally closed (N.C.) contacts. When the engine temperature is too high, switch contacts close, and the engine shuts down automatically.

THE MANUFACTURER RECOMMENDS THAT THE GENERATOR BE TESTED FOR ADEQUATE COOL- ING.
