Section 7 – Post Installation

PRIMEPACT 66G and 66LP Recreational Vehicle Generators

7.1POST INSTALLATION TESTS

The air-cooled generator set was factory tested and adjusted. You 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 applications. When making adjustments, however, be careful to avoid overspeeding the engine.

7.2BEFORE INITIAL START-UP

Before starting, complete the following:

1.Check the engine crankcase oil level and, if neces- sary, 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 accordance with applicable fuel codes. All fuel shutoff valves in the fuel supply lines must be open.

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 permitted. You must be sure no gasoline fuel vapors enter the vehicle interior.

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

NOTE:

The generator set was thoroughly tested and adjust- ed at the factory before shipping. No additional adjustment should be necessary. Only qualified ser- vice technicians who have been trained should per- form adjustments outlined in this manual.

7.4TESTING UNDER LOAD

Apply electrical loads equal to about 75 to 100 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 air- flow is available. You must 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.

GENERAC RECOMMENDS THAT YOU TEST THE GENERATOR FOR ADEQUATE COOLING.

7.3INITIAL START

When you are absolutely certain that the unit has been properly 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, Section 2.5, “Starting the Generator” (Page 8), for cranking and starting instructions. The engine may require more cranking for initial start- ing since the fuel lines have to be primed (use of the primer switch will 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.

5.When all tests and adjustments at no-load are com- pleted, apply electrical loads and check for proper operation under load. See Section 7.4. Run the unit at least 30 minutes with loads applied.

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