PRIMEPACT 66G and 66LP Recreational Vehicle Generators
II POST 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.
-A
WARNING
A~
A D o not make any unnecessary adjustments.
Factory settings are correct for most applications.
When making adjustments, however, be careful to
avoid overspeeding the engine.
12 BEFORE 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.
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.
DANGER

.
A 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.
13 INITIAL START
When you are absolutely certain that the unit has been
properly installed and prepared for use, start the engine
as follows:

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.
7.4 TESTING 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.
Turn off all electrical loads. Do this by setting the
generator’s main circuit breakers to their “OFF” (or
open) position.
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).
Let the engine warm up for about five minutes to
allow internal temperatures to stabilize.
Carefully inspect the engine/generator for fuel, oil
and exhaust system leaks. Before proceeding to the
next step, correct any leakage immediately.
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.
Turn off all electrical loads by setting the generator’s
main circuit breakers to their “OFF” (or open) posi­
tion.
