QUIETPACT™ 75D Recreational Vehicle Generator

CHECKS

3.1POST INSTALLATION TESTS

The generator set was factory-tested and adjusted. It is not necessary 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.

5.When all tests and adjustments at no-load are completed, apply electrical loads and check for proper operation under load. See Section 3.4. Run the unit at least 30 minutes, with loads applied.

6.Turn off all electrical loads by setting the genera- tor’s line breakers to their “OFF” (or open) posi- tion.

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

3.2BEFORE INITIAL STARTUP

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. Fuel lines must have been properly purged and leak-tested in accordance with applicable fuel codes. All fuel shutoff valves in the fuel supply lines must be open.

3.3INITIAL 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 line breakers to their “OFF” (or open) position.

2.Refer to Part I, Section 2.4, “Starting the Generator”, for cranking and starting instruc- tions. The engine may require more cranking for initial starting, since the fuel lines have to be primed (use of the preheat switch will operate the generator’s electrical fuel pump and shorten this time).

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.

The generator set was thoroughly tested and

!adjusted at the factory before shipping. No additional adjustment should be necessary. Only trained, qualified service technicians should perform adjustments outlined in this manual.

3.4TESTING UNDER LOAD

Apply electrical loads equal to about 50 to 75 percent 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 coolant temperature switch. The switch has nor- mally open (N.O.) contacts. When the engine coolant temperature is too high, switch contacts close, and the engine shuts down automatically.

GENERAC RECOMMENDS THAT THE GENERA- TOR BE TESTED FOR ADEQUATE COOLING.
