Generac NP-50G Recreational Vehicle Generator
AUTOMATIC CHOKE
The engine is equipped with an automatic choke that consists
of two main components — choke solenoid and prechoke.
■ CHOKE SOLENOID_
During engine cranking (start/stop switch at START), a solid
state choke module signals the choke solenoid to actuate and
cycle (choke on/choke off) until the engine starts. The choke
solenoid thus opens and closes the carburetor choke valve only
when the engine is cranking. When the engine starts, the choke
stops cycling.
■ PRECHOKE
__
The choke system also has a temperature sensitive metal strip
that adjusts choke valve angle according to ambient temper¬
atures (i.e., in cold ambient temperatures, choke valve closes
more). Once the engine starts, an element heats the tem¬
perature-sensitive strip to a normal operating condition, opening
the choke valve. This may take about 3 minutes in cooler
weather.
BEFORE STARTING THE ENGINE
IMPORTANT: Instructions and information in this manual
assume the generator has been properly installed, connected,
serviced, tested and adjusted by a qualified installation tech¬
nician or installation contractor.
■ INSTALLATION_
Generator installation must have been properly completed so
it complies with all applicable codes, standards and regula¬
tions and with the manufacturer's recommendations.
■ ENGINE LUBRICATION_
Have engine crankcase properly serviced with recommended
oil before starting. Refer to MAINTENANCE and SPECIFI¬
CATIONS sections for oil servicing procedures and
recommendations.
CAUTION: Any attempt to crank or start the engine
A
before you have property serviced it with the recom-
mended oil may result in an engine failure.
■ FUEL SUPPLY_
The engine must have adequate supply of proper fuel to oper¬
ate. Before starting, check that sufficient fuel is available.
NOTE:
On some installation, the generator engine may "share"
the vehicles gasoline fuel tank with vehicle engine. Some instal¬
lations may provide separate fuel tanks for generator and
vehicle engine.
■ COOLING AND VENTILATING AIR
Air inlet and outlet openings in generator compartment must
be open and unobstructed for continued proper operation.
Without sufficient cooling and ventilating airflow, engine-gen¬
erator quickly overheats which causes it to shutdown or may
damage the generator.
■ ENGINE EXHAUST GAS_
Before starting the generator engine, you should be sure there
is no way for exhaust gases to enter the vehicle interior and
endanger people or animals. Close windows, doors and other
openings in the vehicle that, if open, might permit exhaust gases
to enter the vehicle.
DANGER: The generator engine gives off DEADLY
carbon monoxide gas through its exhaust system.
This dangerous gas, if breathed in sufficient con¬
centrations, can cause unconsciousness or even
death. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOXIDE
POISONING ARE (a) inability to think coherently;
(b) vomiting; (c) twitching muscles; (d) throbbing
temples; (e) dizziness; (f) headaches; (g) weak¬
ness and sleepiness. IF YOU FEEL ANY OF THESE
SYMPTOMS, MOVE INTO FRESH AIR IMMEDI¬
ATELY. IF SYMPTOMS PERSIST, GET MEDICAL
HELP.
STARTING THE GENERATOR
IMPORTANT: Read the vehicle manufacturer's instructions.
The owner/operator should become familiar with the vehicle
in which this generator is installed. Differences exist between
vehicles. For example, some vehicles may use a transfer
switch to isolate dockside power from the generator, while other
vehicles may use an isolating receptacle. Some vehicles may
be equipped with a DC converter which allows the generator
to power certain DC lighting and other DC loads.
To start the generator from either the generator control panel
or from the optional Remote Panel, proceed as follows on page
9.
