OPERATION
(jti
Section 2 - Operation
Series QP55-C Recreational Vehicle Generator
2.3 AUTOMATIC CHOKE
The engine is equipped with an automatic choke
that consists of two main components: a choke
solenoid and prechoke.
♦ 2.3.1 CHOKE SOLENOID_______________________ __
During engine cranking (Start/Stop switch at
START), a solid-state choke module signals the
choke
solenoid to activate 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,
♦ 2.3.2 PRECHOKE _______________________________
The choke system also has a temperature-sensitive
metal strip that adjusts choke valve angle accord­
ing to ambient temperatures (i.e., in cold ambient
temperatures, choke valve closes more). Once the
engine starts, an element heats the temperature-
sensitive strip to a normal operating condition,
opening the choke valve. This may take about three
minutes in cooler weather.
2.4 BEFORE STARTING THE ENGINE
NOTE:
Instructions and information in this manual
assume the generator has been properly
installed, connected, serviced, tested and
adjusted by a qualified installation technician or
installation contractor.
♦ 2.4.1 INSTALLATION __________________________ __
Generator installation must have been properly
completed so it complies with all applicable codes,
standards and regulations and with the manufac­
turer's recommendations.
♦ 2.4.2 ENGINE LUBRICATION______________________
Have the engine crankcase properly serviced with the
recommended oil before starting. Refer to Section
1.5.4 (Page 6) and Sections 3.1 and 3.2 (Page 12) for
oil servicing procedures and recommendations.
---------ik CAUTION M. ---------------------
A
Any attempt to crank or start the engine before
you have properly serviced it with the recom­
mended oil may result in an engine failure.
♦ 2.4.5
FUEL SUPPLY_____________________________
The engine must have an adequate supply of prop­
er fuel to operate. Before starting it, check that suf­
ficient fuel is available.
NOTE:
Depending on the installation, the generator
may have either a separate fuel tank, or it may
“share” the vehicle engine’s fuel tank.
♦ 2.4.4 COOLING AND VENTILATING AIR
Air inlet and outlet openings in the generator com­
partment must be open and unobstructed for con­
tinued proper operation. Without sufficient cooling
and ventilating airflow, the engine/generator quick­
ly overheats, which causes it to shut down and may
damage the generator,
♦ 2.4.5 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
A
2.5
The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentra­
tions, can cause unconsciousness or even death.
Never operate the generator set with the vehicle
inside any garage or other enclosed area. DO NOT
OPERATE THE GENERATOR IF THE EXHAUST SYS­
TEM IS LEAKING OR HAS BEEN DAMAGED. SYMP­
TOMS OF CARBON MONOXIDE POISONING ARE
(a) inability to think coherently; (b) vomiting; (c)
twitching muscles; (d) throbbing temples; (e) dizzi­
ness; (f) headaches; (g) weakness; and (h) sleepi­
ness. IF YOU FEEL ANY OF THESE SYMPTOMS,
MOVE INTO FRESH AIR IMMEDIATELY. IF SYMP­
TOMS PERSIST, GET MEDICAL HELP.
STARTING THE GENERATOR
NOTE:
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 gen­
erator, 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.
