Generac Power Systems 0661-5 - Manual (Page 30)

POST INSTALLATION TESTS
The air cooled generator set was factory tested and
adjusted using gasoline as fuel. You should not be
required to adjust the unit any further except under
special circumstances.
WARNING; Do not make any unnecessary adjust­
ments. Factory settings are correct for most appli­
cations. When making adjustments, however, be
careful to avoid overspeeding the engine.
BEFORE INITIAL START UP
Before starting, complete the following:
1. Check engine crankcase oil level and, if necessary, fill to
dipstick FULL mark with the recommended oil. Do not fill
above FULL mark.
2. Check the fuel supply. Fuel lines must have been proper­
ly purged and leak tested in accordance with applicable
fuel-gas codes. All fuel shutoff valves in the fuel supply
lines must be open.
DANGER: If an LP (propane) gas fuel system has
been installed, it must mave been properly tested
for leaks before operating the system in compli­
ance with ANSI A119.2/NFPA 501C. No leakage is
permitted. You must be sure no gaseous fuel
vapors enter the vehicle interior.
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 genera­
tor main circuit breaker to the “OFF’ or “OPEN” position.
2. Refer to the Owner's Manual shipped with unit for crank­
ing and starting instructions. The engine may require
more cranking for initial starting since the fuel lines have
to be primed.
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 generator main
circuit breaker to “OFF” or “OPEN.”
7. Let the unit run at no-load for a few minutes to stabilize
internal engine-generator temperatures. Then, shut down
the engine.
IMPORTANT: THE GENERATOR SET WAS THOR­
OUGHLY TESTED AND ADJUSTED AT THE FAC­
TORY
BEFORE SHIPPING. NO ADDITIONAL
ADJUSTMENT SHOULD BE NECESSARY. ONLY
QUALIFIED SERVICE TECHNICIANS WHO HAVE
BEEN TRAINED SHOULD PERFORM ADJUST­
MENTS OUTLINED IN THIS MANUAL.
TESTING UNDER LOAD
Apply electrical loads equal to about 75-100% 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 over­
heat during prolonged operation.
NOTE: The generator engine is equipped with a high
temperature switch. The switch has normally-open
(N.O.) contacts. When the temperature is too high,
switch contacts close, and engine shuts down auto­
matically.
IMPORTANT: GENERAC RECOMMENDS THAT
YOU TEST THE GENERATOR FOR ADEQUATE
COOLING.
