Section 2 – Operation
IMPACT-36 plus II Recreational Vehicle Generator
2.1.4 COOLING AND VENTILATING AIR
Air inlet and outlet openings in the generator com-
partment must be open and unobstructed for contin-
ued proper operation. Without sufficient cooling and
ventilating air flow, the engine-generator quickly over-
heats, which causes it to automatically shutdown.
Overheating could also damage the unit or the vehicle.
2.1.5 ENGINE EXHAUST GAS
Before starting the generator engine, be sure there is
no way for exhaust gases to enter the vehicle interior
and endangering people or animals. Close windows,
doors and other openings in the vehicle that, if open,
might permit exhaust gases to enter the vehicle.
The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concen-
trations, 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 SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOX-
IDE POISONING ARE (a) inability to think coher-
ently, (b) nausea, (c) vomiting, (d) twitching
muscles, (e) throbbing temples, (f) dizziness, (g)
headaches, (h) weakness, and (i) sleepiness. IF
EXPERIENCING ANY OF THESE SYMPTOMS,
MOVE INTO FRESH AIR IMMEDIATELY. IF SYMP-
TOMS PERSIST, GET MEDICAL HELP. Shut down
the generator and do not operate it until it has
been inspected and repaired.
Never sleep in the vehicle while the genset is
running unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installa-
tion manual. Make sure there is ample fresh air
when operating the genset in a confined area.
2.2 STARTING THE GENERATOR
IMPORTANT: READ THE VEHICLE MANUFACTUR-
ER’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 TRANS-
FER SWITCH TO ISOLATE DOCKSIDE POWER
FROM THE GENERATOR, WHILE OTHER VEHI-
CLES 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 crank and start the generator engine, proceed as
follows:
1. Turn OFF electrical loads, using whatever means
provided in the vehicle (such as a main line cir-
cuit breaker or transfer switch).
NOTE:
If the engine is started with the start/stop switch
on the generator control panel, turn OFF loads by
setting the panel’s main breaker to its “OFF” or
“OPEN” position. Electrical load circuits may be
turned ON after the generator has started, stabi-
lized and warmed up.
NOTE:
On gas units, use of the fuel primer is needed only
during the initial startup, after the unit has not
been used for an extended period of time (two
weeks) or the fuel line has been disconnected. The
primer is used to prime the fuel pump and carbu-
retor.
2. To crank and start the engine, hold the start/stop
switch at START. Release the switch when the
engine starts.
If the engine does not start after it has been
cranking for 15 seconds, release the start/stop
switch and try again. Holding the switch for
longer than 15 seconds may damage the
starter motor.
3. Let the engine run at no-load for a few minutes to
stabilize and warm up the engine.
4. Turn ON electrical loads, using whatever means
provided (such as a main circuit breaker or
transfer switch).
NOTE:
If starting a warm generator engine, press the start
switch only slightly to engage the ignition system.
However, press and hold the starter switch for a
minimum of two (2) seconds to energize the field
boost system. If starting the engine without ener-
gizing the field boost system, the generator pro-
duces no output.
2.3 STOPPING THE GENERATOR
1. Turn OFF all electrical loads, using whatever
means provided (such as a main circuit breaker
or transfer switch).
2. Let the generator run at no-load for a few min-
utes, to stabilize internal engine-generator tem-
peratures.
3. Hold Start/Stop switch in its STOP position.
