Safety Rules Series QP55-C Recreational Vehicle Generator
SAVE THE^E INSTRUCTIONS - The manufacturer suggests that these rules for safe
operation be copied and posted in potential hazard areas of the recreational vehicle. Jk
Safety should be stressed to all operators and potential operators of this equipment.
A
WARNING:
The engine exhaust from this product
contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.
11
I This product contains or emits chemicals I known to the state of California to cause
I cancer, birth defects or other reproductive harm.
Study these SAFETY RULES carefully before installing, operating or servicing this equipment. Become familiar with this manual and with the unit. The generator can operate safely, efficiently and reli ably only if it is properly installed, operated and maintained. Many accidents are caused by failing to follow simple and fundamental rules or precautions.
Generac cannot possibly anticipate every possi ble circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed to the unit, are, therefore, not all-inclusive. If you use a procedure, work method or operating technique Generac does not specifically recom mend, you must satisfy yourself that it is safe for you and others. You also must make sure the pro cedure, work method or operating technique that
you choose does not render the generator unsafe.
Despite the safe design of this generator, operating this equipment imprudently, neglecting its maintenance or being careless can cause possible injury or death. Permit only responsible and capable persons to operate or maintain this equipment.
Potentially lethal voltages are generated by
A
these machines. Ensure all steps are taken to render the machine safe before attempting to work on the generator.
Parts of the generator are rotating and/or hot during operation. Exercise care near running generators.
WARNING:
DANGER
GENERAL HAZARDS ^
For safety reasons, Generac recommends
that the installation, initial start-up and mainte nance of this equipment is earned out by a Generac Authorized Service Dealer.
The engine exhaust fumes contain carbon
monoxide, which can be DEADLY. This danger ous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. This exhaust system must be installed properly, in strict compliance with applicable codes and stan dards. Following installation, you must do noth ing that might render the system unsafe or in
noncompliance with such codes and standards. The generator compartment must be completely vapor sealed from the vehicle interior. There
must be no possibility of exhaust fumes entering
the vehicle interior. Never operate this equipment with a leaking or defective exhaust system.
Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit
is operating. Adequate, unobstructed flow of cooling and ven
tilating air is critical to correct generator opera
tion and is required to expel toxic fumes and fuel vapors from the generator compartment. Without
sufficient cooling airflow, the engine/generator
quickly overheats, which causes serious damage
to the generator. Do not alter the installation or
permit even partial blockage of ventilation provi
sions, as this can seriously affect safe operation
of the generator.
When working on this equipment, remain alert at
all times. Never work on the equipment when you
are physically or mentally fatigued. Inspect the generator regularly, and contact your
nearest Generac Authorized Service Dealer imme
diately for parts needing repair or replacement.
Before performing any maintenance on the gen
erator, disconnect its battery cables to prevent
accidental start up. Disconnect the cable from
the battery post indicated by a NEGATIVE, NEG
or (-) first. Reconnect that cable last. Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating
conditions from leaking exhaust gases, fuel leak
age, oil leakage, etc.

SAFETY RULES
A
ELECTRICAL HAZARDS
The generator covered by this manual produces
dangerous electrical voltages and can cause fatal electrical shock. Avoid contact with bare wires, terminals, connections, etc., while the unit is running. Ensure all appropriate covers, guards and barriers are in place before operating the generator. If you must work around an operating unit, stand on an insulated, dry surface to reduce shock hazard.
Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.
During installation onto the vehicle, have the gen
erator properly grounded (bonded) either by solid mounting to the vehicle frame or chassis, or by means of an approved bonding conductor. DO NOT disconnect the bonding conductor, if so equipped. DO NOT reconnect the bonding conduc tor to any generator part that might be removed or disassembled during routine maintenance. If the grounding conductor must be replaced, use only a flexible conductor that is of No. 8 American Wire Gauge (AWG) copper wire minimum.
In case of accident caused by electric shock,
immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a noncon ducting implement, such as a rope or board, to free the victim from the live conductor. If the vic tim is unconscious, apply first aid and get imme diate medical help.
Never wear jewelry when working on this equip
ment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving com ponents causing injury.
A
A
FIRE HAZARDS
For fire safety, the generator must be installed
and maintained properly. Installation always must comply with applicable codes, standards, laws and regulations. Adhere strictly to local, state and national electrical and building codes. Comply with regulations the Occupational Safety and Health Administration (OSHA) has estab lished. Also, ensure that the generator is installed in accordance with the manufacturer’s instructions and recommendations. Following proper installation, do nothing that might alter a safe installation and render the unit in noncom pliance with the aforementioned codes, stan dards, laws and regulations.
Keep a fire extinguisher in the vehicle at all times.
Extinguishers rated “ABC” by the National Fire Protection Association are appropriate for use on the recreational vehicle generator electrical sys tem. Keep the extinguisher properly charged and be familiar with its use. If you have any question pertaining to fire extinguishers, consult your local fire department.
EXPLOSION HAZARDS
Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no com bustible materials are left in the generator com partment, or on or near the generator, as FIRE or EXPLOSION may result. Keep the area surround ing the generator clean and free from debris.
Gasoline is extremely FLAMMABLE and its vapors are EXPLOSIVE. Do not permit smoking, open flame, sparks or any source of heat in the vicini ty while handling gasoline. Comply with all laws governing the storage and handling of gasoline.
This generator may use liquid propane (LP) gas as
a fuel. LP gas is highly EXPLOSIVE. The gas is heavier than air and tends to settle in low areas where even the slightest spark can ignite the gas and cause an explosion.

1.2 GENERATOR APPLICABILITY
These generators have been designed and manu
factured for supplying electrical power for recre ational vehicles. You should not modify the genera tor or use it for any application other than for what it was designed. If there are any questions pertain ing to its application, write or call the factory. Do not use the unit until you have been advised by a competent authority.

DANGER

-A
For fire safety, the generator must have been
A
properly installed in compliance with ANSI
119.2-1975/NFPA 501C-1974, "Standard for Recreational Vehicles, Part III - Installation of Electrical Systems." The generator also must have been installed in strict compliance with the manufacturer's detailed installation instruc tions. After installation, do nothing that might render the unit in noncompliance with such codes, standards and instructions.
You can use this generator to supply electrical power
for operating 120 volt, single-phase, 60 Hertz, AC electrical loads. These loads can require up to 5,500
watts (5.5 kW) of power, but carmot exceed 46 AC
amperes of current at 120 volts.
1.4 GENERATOR AC CONNECTION SYSTEM
This generator set is equipped with dual stator AC
power windings. These two-stator windings supply
electrical power to customer electrical loads by means of a dual two-wire connection system. Note, however, that the neutral is grounded.
The generators have been installed so that it powers
120-volt AC loads (Figure 1.1).
Figure 1.1 - Connections for 120 Volts Only
-------Ml caution Jk
Do not overload the generator. Some installa
A
tions may require that electrical loads be alter nated to avoid overloading. Applying excessive ly high electrical loads may damage the genera tor and may shorten its life. Add up the rated watts of all electrical lighting, appliance, tool and motor loads the generator will power at one time. This total should not be greater than the wattage capacity of the generator. If an electrical device nameplate gives only volts and amps, multiply volts times amps to obtain watts (volts X amps = watts). Some electric motors require more watts of power (or amps of cur rent) for starting than for continuous operation.
---------------
1.3 SAFETY
Before attempting to use the generator set, careful ly read the “Safety Rules” section of this manual. Comply strictly with these rules to prevent acci dents and damage to equipment and/or property.
We suggest copying and posting the “Safety Rules”
in potential hazard areas of the vehicle. Stress safe ty to all operators and potential operators of this equipment.
1.5 SPECIFICATIONS

#1.5.1 FUEL REQUIREMENTS

The generator is equipped with a gasoline fuel sys
tem as standard equipment. Depending on the installation, the generator may have either a sepa rate fuel tank, or it may “share” the vehicle engine’s
fuel tank.
NOTE:
Some installations using a “shared” fuel tank
may have a generator fuel pickup tube that is
shorter than the vehicle engine’s pickup tube. Such an arrangement causes the generator engine to “run out of gas” while adequate fuel for the vehicle remains in the tank.
To reduce lead and carbon deposits use high quality UNLEADED gasoline with the generator. Leaded REGULAR grade gasoline is an acceptable substitute.

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 temperature­sensitive 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:

♦ 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.
__________________________
__
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
The generator engine gives off DEADLY carbon
A
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.
♦ 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.

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.
Section 2 - Operation
Series QP55-G Recreational Vehicle Generator

OPERATION

(ÿtï

To start the generator from either the generator
control panel or from the optional remote panel, proceed as follows;
1. Turn OFF electrical loads using the means pro vided in your vehicle (such as a main line cir cuit breaker or transfer switch).
NOTE:
If starting from the generator control panel, turn OFF loads by setting the generator’s main circuit breaker to the OFF (or open) position. If starting from a remote panel, turn OFF loads using the means provided in the vehicle (such as a main circuit breaker). Electrical load circuits will be turned ON after the generator has start ed, stabilized and warmed up.
2. If you have not started the engine in more than two weeks, press the Fuel Pump Primer switch and hold it for about five seconds to prime the fuel system. However, if the engine is warm, skip Step 2.
3. Hold the engine Start/Stop switch in the START position to crank the engine. Release the switch when the engine starts.
-------
Mk CAUTION M.
If the engine does not start after it has been
k cranking for 15 seconds, release the Start/Stop
switch and try again. Holding the switch for longer than 15 seconds can damage the starter motor.
Let the engine run at no-load for a few minutes

2.6 STOPPING THE GENERATOR
1. Turn OFF all electrical loads using the means provided (such as a main circuit breaker or transfer switch).
2. Let generator run at no-load for a few minutes, to stabilize internal engine generator temperatures.
3. Place the Start/Stop switch in its STOP position.

♦ 2.7.1 LEHING THE ENGINE STABILIZE

The generator supplies correct rated voltage only at
the proper governed speed. Some electrical appli ances may be extremely sensitive to voltage. Incorrect voltages can damage such appliances.
If electrical loads are applied at reduced operating
speeds, such loads imposed on the engine when suf ficient power is not available may shorten engine life. Never turn ON electrical loads until after the genera tor engine has started and stabilized at no-load.
2.8
SUIVIIVIER/WINTER HEAT RISER SYSTEM
Under certain weather conditions, it is possible for
ice to form in the venturi area of the carburetor. This condition can be very dangerous because it
can prevent the governor system from functioning
properly, which results in a “runaway” engine. The most common weather conditions leading to
this problem are temperatures in the range of 25° F
to 35° F (-4° C to 1.7° C), along with high humidity. This ice formation also can be attributed to the load
being applied during these weather conditions.
Generators running with no-load or light loads
applied usually have the most problems. The Summer/Winter Lever (Figure 2.4) should be in
the WINTER position for ambient temperatures below 40° F (4.4° C) and in the SUMMER position
for ambient temperatures above 40° F (4.4° C). When the heat riser is in the SUMMER (down) posi
tion (Figure 2.4), air is drawn into the air cleaner from the upper intake tube.
Figure 2.4 - Heat Riser System
WINTER POSITION
2.7 APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator,
observe these guidelines:
• Before applying electrical loads, let the generator stabilize and warm up for a minute or two.
® DO NOT overload the generator.
When the heat riser is in the WINTER (up) position,
air is drawn from the lower intake tube, which is positioned to draw the heated air near the exhaust manifold.
To prevent carburetor icing, the owner/operator
should physically position the heat riser to the proper position dependent on the temperature.

Section 2 - Operation Series QP55-G Recreational Vehicle Generator

• 2.8.1 DO NOT OVERLOAD THE GENERATOR

You can read the rated wattage/amperage capacity of your generator on the generator data decal (see Section 1.1 on Page 4).
Applying electrical loads in excess of the unit’s rated capacity will cause the engine/generator to automatically shut down.
To avoid overloading, add up the wattage of all con-
nected electrical lighting, appliance, tool and motor loads. This total should not be greater than the generator’s rated wattage capacity.
Most lighting, appliance, tool and motor loads indicate their required watts on their nameplate or data plate. For light bulbs, simply note the wattage rating of the bulb.
• If a load does not show its rated wattage, multi ply that load’s rated VOLTS times AMPS to obtain WATTS.
Induction type motors (such as those that run the vehicle’s furnace fan, refrigerator, air condi tioner, etc.) need about 2-1/2 time more watts of power for starting than for running (for a few seconds during motor starting). Be sure to allow for this when connecting electrical loads to the generator. First, figure the watts needed to start electric motors in the system. To that figure, add the running wattages of other items that will be operated by the generator.
• Do not apply heavy electrical loads for the first two or three hours of operation.
2.10 PROTECTION SYSTEMS

♦ 2.10.1 LOW OIL PRESSURE SWITCH

This switch (Figure 2.5) has normally closed (N.C.)
contacts that are held open by engine oil pressure during cranking and operating. Should oil pressure drop below a preset level, switch contacts close, and the engine automatically shuts down. The unit should not be restarted until oil is added.

♦ 2.10.2 HIGH TEMPERATURE SWITCH

This switch (Figure 2.5), which has normally open
(N.O.) contacts, is mounted near the oil filter. The contacts close if the temperature should exceed approximately 293° F (145° C), initiating an engine shutdown.

2.9 OPERATING PRECAUTIONS
—A Emm A
Never operate the recreational vehicle genera
A
tor set while the vehicle is parked over dry leaves, dry grass or any other combustible sub stance. The generator's exhaust system becomes extremely hot and can cause fire if it is too close to combustible materials.
The generator's exhaust system gives off
DEADLY carbon monoxide gas. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness and even death.
Never operate the generator set with the vehi cle inside any garage or other enclosed area.
Never operate the generator if it has a leaky exhaust system. Close windows in the vicinity of the generator exhaust outlet and take any other steps to prevent exhaust gases from entering rooms or areas occupied by people or animals.

diode and resistor that are not part of the automat ic choke circuit. These two components are part of a "field boost” circuit (Figure 2.6). During engine cranking only, a positive DC (battery) voltage is delivered through the diode, resistor, brushes and slip rings, and the generator rotor. Application of this voltage to the rotor “flashes the field” whenev er it is started. Flashing of the field each time the generator starts makes sure that a sufficiently
strong magnetic field is available to produce “pick
up” voltage in the stator windings.

A solid-state voltage regulator (Figure 2.7) controls
the generator’s AC output voltage. This regulator supplies an excitation current to the rotor. By reg ulating the rotor’s excitation current, the strength of its magnetic field is regulated and, in turn, the
voltage delivered to connected electrical loads is
controlled. When the AC frequency is 60 Hertz, volt age is regulated at 120 volts (voltage-to-frequency ratio is 2-to-l).

2.11 AODITIONAUNFORlVIATiON
• 2.11.1 25-HOUR BREAK-IN PERIOD_________________
The first 25 hours of operation is the break-in peri
od for the generator. Properly breaking in the gen erator is essential to minimize fuel consumption and provide maximum engine performance. During this 25-hour break-in period, follow this procedure:
• Run the unit at varying electrical loads to help seat the engine piston rings properly.
• Check the engine oil level frequently. Add oil if needed. It is normal for the generator engine to consume more oil than is normal until the piston rings have properly seated.
• For the 75-hour operation following the break-in period, avoid light electrical loads. Load the generator at 50 percent (or more) of its rated wattage capacity. Repeated light loads during these 75 hours can cause improper seating of engine piston rings, resulting in blowby and high oil consumption.
• After operating the unit for 25 hours, complete the tasks recommended under Section 2.11.2.
• 2.11.2 25-HOUR CHECK-UP
After the 25-hour break-in period, contact a Generac Authorized Service Dealer for the following maintenance. The vehicle owner is responsible for any charges:
• Change the engine crankcase oil and oil filter.
• Check the oil level.
• Inspect the cooling and ventilation openings.
• Check the engine carburetor adjustments.
• Check the engine ignition system.
• Inspect the entire electrical system.
• Inspect the engine exhaust system.
_______________________
The voltage regulator also incorporates a “voltage
surge protection circuit.” This circuit prevents trou blesome surges in the generator AC output voltage. Voltage surge is a common cause of damage to elec

MAINTENANCE
Section 3 - Maintenance Series QP55-G Recreational Vehicle Generator

♦ 2.11.5 EFFEQS OF MOISTURE AND DIRT

Keep the generator set as clean and dry as possible. Protect the unit against excessive dust, dirt, corro sive vapors, road splash, etc. Permitting dirt and moisture to accumulate on generator windings will have an adverse effect on the insulation resistance of those windings.
When moisture is allowed to remain in contaet with windings, some of the moisture will be retained in voids and cracks in the insulation. This causes a reduced insulation resistance and will eventually cause problems. Dirt will make the problem worse, since dirt tends to hold moisture in contact with windings. Salt (as from sea air) also will worsen the problem since it tends to absorb moisture from the air. Salt and moisture, when combined, form a good electrical conductor.
3.1 CHECKING THE ENGINE OIL LEVEL
P'or oil capacities and requirements, see “Engine Oil Requirements,” Section 1.5.4 (Page 6). Check the engine crankcase oil level at least every eight hours of operation, or before you use it. To check the engine oil level, proceed as follows (see Figure 3.1):
1.
Be sure the generator is as level as possible.
2.
Remove the dipstick and wipe it dry with a clean, lint-free cloth.
3.
Install and tighten the dipstick cap; then, remove it again. The oil level should be at the dipstick “Full” mark.
4.
If necessary, remove the oil fill cap on the rock er cover and slowly add oil until it reaches the dipstick “Full” mark. DO NOT FILL ABOVE THE “FULL" MARK.
Figure 3.1 - Oil Maintenance Features

Mk CAUTION Mk
Never operate the engine with the oil level
A
below the "Add" mark on the dipstick. Doing this could damage the engine.
-------------------
5. Install and tighten the oil fill cap and the dip stick before operating the engine.
3.2 CHANGING THE ENGINE OIL
AND/OR OIL FILTER
• Change the engine oil after the first 25 hours of
operation (after the 25-hour break-in period, see Section 2.11.1, Page 11). Thereafter, change the oil every 50 operating hours. Change the oil more frequently if operating consistently under heavy load or at high ambient temperatures.
• Change the engine oil filter after the first 25
hours of operation, and every 100 operating hours thereafter.
To change the oil and/or oil filter, proceed as
follows (see Figure 3.1):
1. Run the engine until it is thoroughly warmed
up (at least five minutes) then shut OFF the engine. Immediately after the engine shuts OFF, pull
2.
the oil drain hose free of its retaining clip. Remove the cap from the hose and drain the oil into a suitable container. Loosening the oil fill cap will allow the crankcase to drain faster.
After the oil has drained, replace the cap onto the
3. end of the oil drain hose. Retain the hose in the clip. GO TO STEP 7 IF CHANGING OIL ONLY.
With the oil drained, remove the old oil filter by
4. turning it counterclockwise.
Apply a light coating of clean engine oil to the
5. gasket of the new filter.

6. Screw the new filter on by hand until its gasket lightly contacts the oil filter adapter. Then, tighten the filter an additional 3/4 to one turn.
7. Remove the dipstick and wipe it dry with a
clean, lint-free cloth. This will be used later to check the oil level.
8. Remove the oil fill cap on the rocker cover and
slowly add the proper type and amount of rec ommended oil (see Section 1.5.4, Page 6). Periodically use the dipstick to check the oil
level and continue to fill the crankcase until the
oil reaches the dipstick “Full” mark. DO NOT
FILL ABOVE THE “FULL” MARK.
9. Install and tighten the oil fill cap and the dip stick before operating the engine.
10. Start the engine and check for leaks.

3.7 SPARK ARRESTOR MUFFLER
If the generator is not equipped with a spark arrestor exhaust muffler and is to be used on any forest cov ered, brush covered or grass covered unimproved land, you may have to Install a spark arrestor. The spark arrestor must be maintained in effective work ing order by the vehicle owner/operator.
For assistance in ordering, installing and maintain ing spark arrestor exhaust mufflers, contact your nearest Generac Authorized Service Dealer.
Exhaust mufflers supplied by Generac are spark arrestor types. Generac exhaust mufflers for recre ational vehicle generators do not have a spark arrestor screen, but are of the more efficient “toroid” or “swirl” type. To remove carbon and com bustion deposits from such mufflers, remove the plug from the muffler and run the engine for approximately 15 minutes. Shut down the engine, let the muffler cool and install the plug.
-A WARNING A-
Be sure to reinstall the muffler plug tightly.
Engine vibration could cause a loose plug to fail out. Without the plug in place, hot engine exhaust is directed out the opening. This hot exhaust, depending on the installation, could be directed to areas not able to withstand the extreme heat such as wooden floor boards or other flammable material. This could result in a fire.
3.8 CLEANING THE GENERATOR
Keep the generator set as clean and dry as possible. Protect the unit against excessive dust, dirt, corro sive vapors, road splash, etc. Permitting dirt and moisture to accumulate on generator windings will have an adverse effect on the insulation resistance of those windings.
When moisture is allowed to remain in contact with

3.9 BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in
use. The generator battery should be inspected as follows:
♦ Î.9.1 WEEKLY
® Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessaiy.
• Check the batteiy fluid level of unsealed batteries and, if necessary, fill with Distilled Water Only. Do not use tap water in batteries.
♦ 5.9.2 EVERY SIX MONTHS
• Have the state of charge and condition checked. This should be done with an automotive-type battery hydrometer.
NOTE:
Servicing of the battery is to be performed or supervised by personnel knowledgeable of bat teries and the required precautions. Keep mnau­thorized personnel away from batteries.
Damage will result if the battery connections
are made in reverse.
DANGER
Do not dispose of the battery in a fire. The
A
battery is capable of exploding. Storage batter ies give off explosive hydrogen gas. This gas can form an explosive mixture around the bat
tery for several hours after charging. The
slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury.
Any area that houses a storage battery must be
properly ventilated. Do not allow smoking, open flame, sparks, or any spark producing tools or equipment near the battery. Discharge
static electricity from your body before touch
ing the battery by first touching a grounded
metal surface. A battery presents a risk of electrical shock
A
and high short circuit current. The following
precautions are to be observed when working on batteries:
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery;
• Disconnect any charging source prior to connecting
or disconnecting battery terminals; and
• Do not use any jumper cables or booster battery to crank and start the generator engine. If any battery has discharged, remove it for recharging.
-A WARNING A-
Do not open or mutilate the battery. Released
A
electrolyte has been known to be harmful to the skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
A
harmful to the skin and eyes. It is electrically conductive and corrosive. The following procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek
medical attention; and
• Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to use a solution of 1 pound (500 grams) bicarbonate of soda to 1 gallon (4 liters) or water. The bicar bonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried.

during operation. Exercise care near running generators.
Ml GENERAL HAZARDS A
For safety reasons, Generac recommends
that the installation, initial start-up and mainte nance of this equipment is carried out by a Generac Authorized Service Dealer.
The engine exhaust fumes contain carbon
monoxide, which can be DEADLY. This danger ous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. This exhaust system must be installed properly, in strict compliance with applicable codes and stan dards. Following installation, you must do noth ing that might render the system unsafe or in
noncompliance with such codes and standards. The generator compartment must be completely vapor sealed from the vehicle interior. There
must be no possibility of exhaust fumes entering
the vehicle interior. Never operate this equipment with a leaking or defective exhaust system.
Keep hands, feet, clothing, etc., away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating.
Adequate, unobstructed flow of cooling and ven
tilating air is critical to correct generator opera tion and is required to expel toxic fumes and fuel vapors from the generator compartment. Without sufficient cooling airflow, the engine/generator quickly overheats, which causes serious damage to the generator. Do not alter the installation or permit even partial blockage of ventilation provi sions, as this can seriously affect safe operation of the generator.
When working on this equipment, remain alert at
all times. Never work on the equipment when you are physically or mentally fatigued.
Before performing any maintenance on the gen
erator, disconnect its batteiy cables to prevent accidental start up. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG or H first. Reconnect that cable last.
Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leak age, oil leakage, etc.
Never insert any tool or other object through
openings in the generator interior, even if the unit is not running. You might seriously injure
yourself or damage the equipment.

ELECTRICAL HAZARDS
The generator covered by this manual produces
dangerous electrical voltages and can cause fatal
electrical shock. Avoid contact with bare wires, terminals, connections, etc., while the unit is running. Ensure all appropriate covers, guards
and barriers are in place before operating the generator. If you must work around an operating unit, stand on an insulated, dry surface to reduce shock hazard.
Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.
During installation onto the vehicle, properly
ground (bond) the generator either by solid mounting to the vehicle frame or chassis, or by means of an approved bonding conductor. DO NOT connect the bonding conductor to any gen erator part that might be removed or disassem bled during roi.itine maintenance. If the ground ing conductor must be replaced, use only a flex ible conductor that is of No. 8 American Wire Gauge (AWG) copper ware minimum.
If the vehicle electrical circuits can be powered by
any other source of electricity (such as a “dock­side” power receptacle), there must be no possi
bility of connecting the different power sources to
the vehicle circuits at the same time. The dock­side (utility) power source must be positively iso lated from the vehicle circuits whenever the gen erator is operating. Failure to isolate the vehicle circuits from the dockside power supply when
the generator is running may result in damage to the generator or serious injury or death to dock-
side (utility) power workers due to backfeed of
electrical energy. In case of accident caused by electric shock,
immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a noncon ducting implement, such as a rope or board, to free the victim from the live conductor. If the vic tim is unconscious, apply first aid and get imme diate medical help.
Never wear jewelry when working on this equip ment. Jeweliy can conduct electricity resulting In electric shock, or may get caught in moving com ponents causing injury.

FIRE HAZARDS
For fire safety, the generator must be installed
and maintained properly. Installation always must comply with applicable codes, standards, laws and regulations. Adhere strictly to local, state and national electrical and building codes. Comply with regulations the Occupational Safety and Health Administration (OSHA) has estab lished. Also, ensure that the generator is installed in accordance with the manufacturer’s instructions and recommendations. Following proper installation, do nothing that miglit alter a safe installation and render the unit in noncom pliance wath the aforeinentioried codes, stan dards, laws and regulations.
Keep a fire extinguisher in the vehicle at all times.
ICxtinguishers rated “ABC” by the National Fire Protection Association arc appropriate for use on tfie recreational vehicle generator electrical sys tem. Keep the extinguisher properly charged and
be familiar with its use. If you have any question
pertaining to fire extinguishers, consult your local fire department.
A
EXPLOSION HAZARDS
Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Einsure that no com bustible materials are left in the generator com partment, or on or near the generator, as F'IFíE or EXPLOSION may result. Keep the area surround ing the generator clean and free from debris.
Gasoline is extremely FLAMMABLE and its vapors are EXPLOSIVE. Do not permit smoking, open flame, sparks or any source of heat in the vicini ty while handling gasoline. Comply with all laws governing the storage and handling of gasoline.
Fuel lines must be properly installed and fastened, and free of leaks. There must be no possibility of gasoline vapors entering the vehicle interior.
You are required to install an approved, flexible,
nonconductive fuel line between the generator fuel connection point and rigid fuel lines.
If the generator is equipped with a liquid propane (LP) gas fuel system, install the unit so it com plies with all codes, standards and regulations pertaining to such systems. LP gas is highly explosive. The gas tends to settle in low areas where even the slightest spark can ignite it and cause an explosion. Do not allow gas vapors to enter the vehicle.

Section 2 - Installation Series QP55-C Recreational Vehicle Generator
2.1 LOCATION AND SUPPORT

• 2.1.1 GENERATOR LOCATION

The most desirable location for the generator set is between the vehicle's main frame members.
However, this is seldom possible. Most units must
be installed on the side of the vehicle and are diffi
cult to reinforce.
Plan the generator location based on the following:
• The generator set must be installed on a frame work that is part of the recreational vehicle, as
outlined in Section 2.1.2.
• The location must provide an access opening that
is large enough to permit generator removal (unless the generator is to be removed from underneath the supporting framework).
• The location must provide easy access to fre
quently serviced components, such as filters, oil drains, spark plugs and other common mainte
nance parts.
The location must provide sufficient room to
allow minimum clearances as outlined in Section
2.2. If sound insulation is to be used on the com partment walls and ceiling, the minimum recom
mended applies to the space between the gener
ator and such insulation.
• The location must provide adequate cooling and ventilating airflow for the generator without a
great deal of work and expense.

• 2.1.2 GENERATOR SUPPORT

The generator must be securely attached to a metal framework that has been made part of the vehicle frame structure by bolting or welding. The metal
framework on which the generator will rest and
which will restrain the generator set should consist
of at least two horizontal beams. These beams should consist of (a) 1-1 /2-inch square, 11-gauge steel tubing OR (b) 1-1/2-inch, 11-gauge angle iron, A typical supporting frame with horizontal support tubing, is shown in Figure 2.1.
The generator can be installed so that it sits on top
of the horizontal support tubing if the vehicle design permits. Another method is to suspend the generator below the horizontal support tubing by means of suitable, structurally sound metal frame work. The following general rules apply:
• Vehicle construction MUST be capable of sup porting the weight of the generator.
_____________________
Whether the generator is mounted above the hor
izontal support tubing or suspended below the tubing, the supporting frame used must be
structurally sound.
If the generator cannot be bolted directly to
the supporting frame or support tubing, consid er using additional tubing, angle brackets or other supports to give the supporting frame
sufficient strength.
Figure 2.1 - Typical Horizontal Support Frame

♦ 2.1.5 GENERATOR RESTRAINT

Use four 3/8"-16 hardened steel bolts (Grade 5) to fasten the generator to the supporting frame or the
support tubing. These bolts must pass through (a) the generator mounting base, (b) the compartment floor (if a compartment is used) and (c) the support ing framework (Figure 2.3). All bolts must be long
enough so that when tight, at least three threads are visible past the retaining lock nuts. Refer to Section
2.2 for the location of the generator mounting holes.

INSTALLATION
2.2 GENERATOR COMPARTIVIENTS
Whether the generator set is being installed inside a
compartment specifically manufactured to house a generator or inside a compartment that the installer constructs, the compartment MUST meet certain specifications as outlined in the following sections:
♦ 2.2.1 COMPARTMENT SIZE
Plan the compartment size carefully. Provide a min imum clearance of 1/2 inch (13 mm) on the front and top, 1 inch (25 mm) on the sides, and 1/2 inch (13 mm) from the back for air circulation AFTER the compartment has been lined with metal and sound insulation (Figure 2.4).
Refer to “Figure 1.2 ­Dimensions” on Page 21.
Figure 2.4 - Clearances
♦ 2.2.2 COMPARTMENT CONSTRUaiON
• The generator compartment should be either constructed of, or lined with, 26-gauge galva nized steel.
Aluminum is NOT an acceptable alternative to galvanized steel due to aluminum’s low melting point.
• If the compartment is lined with galvanized steel, it may be constructed of any material. Generac recommends that the compartment be construct
ed of 1/2-inch thick plywood (not strandboard), with the floor made of a double thickness of 1/2­inch pl}nvood with the grain of the wood at cross
section for added strength (Figure 2.5).
____________________
NOTE:
Major Features and
* •
NOTE:
Figure 2.5 - Typical Compartment Construction
CROSS-SECTION VIEW LINING
If constructing a compartment, line the exterior (underside) of the compartment floor with 26­gauge galvanized steel.
• All seams, splices and joints of the compartment walls (unless vapor tight by design) should be caulked to prevent poisonous, flammable or explosive vapors from entering the vehicle interior.
NOTE:
Caulking must be done so that the caulking mate rial will stay in place permanently. Pressing such materials as putty tape onto joints and seams is NOT acceptable. A high quality silicone rubber base sealant is recommended.
Holes and openings made in the compartment walls to allow for the passage of electrical con duit, conductors, hoses, cables, etc., into the vehicle living area must be sealed vapor tight with silicone rubber base sealant.
• If flexible metal conduit is used, it must be sealed internally at the end where it terminates inside the compartment’s electrical junction box.
NOTE:
Flexible metal conduit, due to its unique con struction, is NOT vapor tight along its entire
length.
• Seams and joints of the galvanized steel (whether used as a liner or for the compartment itself) must be lapped and mechanically secured. Such seams may be manufactured, welded, bolted, riv eted or screwed. Manufactured lock seams are shown in Figure 2.6. Installer constructed com partments typically utilize a standard lap joint.

After the compartment has been metal lined and
vapor sealed, line the compartment interior walls
and ceiling with an approved, nonflammable sound insulating material. See Section 2.2.3.
Do not install any flammable material directly
A
above or around the compartment. Heat, transferred through the compartment structure,
may be sufficient to ignite, char or discolor
seat cushions, fiberboard and other flammable
materials. You may need to use approved nonflammable insulating materials in high
temperature areas.

♦ 2.2.3 SOUND INSULATING MATERIALS

Once installers have determined that a compart ment is properly constructed and metal lined, they can add acoustical material. This may include addi tional sealant or insulating material, to reflect noise away from the vehicle interior.
Sound insulating materials should be of a nonflam mable type. One excellent insulating material is a
1-inch (25 mm) thick fiberglass having a 2-pound
density. When fiberglass is used, its coated side
should face toward the compartment interior.

^ 2.2.4 ACOUSTICS

For additional noise abatement, the installer may wish to consider the following:
• Using special sound insulating materials.
Construction of a special noise abatement compartment.
NOTE:
Any method used to reduce noise must not
adversely affect the flow of cooling and ventilat ing air into or out of the compartment.
In addition to the effective use of sound insulating materials, construction of a special noise abate ment compartment might be considered to reduce noise levels. Such a compartment might be con structed as follows (Figure 2.7);
• Use 5/8-inch thick or 3/4-inch thick plywood in the compartment.
Construct the compartment floor of a double thickness of 5/8-inch or 3/4-inch plywood.
• Line the compartment interior walls and floor, as
well as the underside of the floor, with 26-gauge
galvanized steel.
• Vapor seal all compartment seams and joints.
• Over the galvanized steel lining, install a combi nation of acoustical materials as mentioned in Section 2.2.3.
DANGER
To prevent fire or explosion, do not install any
à
insulation or other absorbent materials on the interior or underside of the compartment floor.
Seal all compartment door edges to prevent noise
leakage around the door perimeter.
Line the compartment door interior (except for air
openings) with suitable, fireproof sound insula tion (such as 1-inch (25 mm) thick fiberglass with a 2-pound density).
Figure 2.7 - Typical Noise Abatement
DANGER
A Do not install sound insulation or any
fflSa absorbent material on the compartment floor
interior. Such materials will become soaked with combustible or explosive vapors and liquids and will become a fire hazard.
Using a combination of sound insulating materials can often reduce noise more effectively than a sin gle material. For example, a sheet of lead or visco elastic material, along with a layer of other acousti cal material, is more effective than when a single
material is used.

• 2.2.5 COMPARTMENT FLOOR CUTOUTS

You must provide openings in the generator com
partment for the following items (Figure 2.8):
• Engine exhaust and cooling air outlets
• Generator cooling air inlet
• Four holes for passage of generator mounting bolts. See Section 2.1.4 (Page 23).

DANGER

Fuel lines and exhaust piping must not pene
trate into the vehicle living area.
Figure 2.8 - Compartment Floor Cutout
23 COOLING AND VENTILATING AIR
It is absolutely essential that an adequate flow of air for cooling, ventilating and engine combustion be supplied to the generator set. Without sufficient airflow, the engine/generator quickly overheats. Such overheating can cause serious operating diffi culties and also may cause fire and personal injury.
The installer must make sure that sufficient air is
available to the generator for cooling, ventilating and combustion. The installer also must provide for a path for exhausting the cooling air to the exterior of a compartment, if so equipped.
Generac* Power Systems, Inc. 35
INSTALLATION
Section 2 - Installation Series QP55-G Recreational Vehicle Generator

DANGER

Never use discharged cooling air for heating or permit
A
such air to enter the vehicle interior.This air contains deadly carbon monoxide gas and other poisonous, flam
mable or explosive gases.

♦ 2.3.1 GENERATOR AIRFLOW

_______________________
Engine operation drives cooling fans for the two-stage cooling air system. A pressure fan draws cooling air into the top of the generator (Figure 2.9). This airflow cools the engtne/generator and electronic compo nents. The second part of the cooling system, a suc tion fan, draws air that is heated from a hot engine into a collector pan at the base of the unit. This heat ed air (although cooler than exhaust muffler) is then deflected out the bottom toward the ground.
Figure 2.9 - Airflow Through Engine/Generator
Figure 2.10 - Air Inlet in Compartment Door
100 SQUARE INCHES UNRESTRICTED MINIMUM OPENINGS
NOTE:
Be sure to meet the minimum clearances illus trated in Figure 2.4 (Page 23).
When the unit is installed on a suspended mount ing system, one of several different methods of sup plying airflow may be used as follows:
• Provide a door in the vehicle skirt having an air inlet opening (Figure 2.11).

♦ 2.5.2 COOLING AIR INLET OPENINGS

The minimum size of the air inlet opening, whether
the generator is housed in a conventional compart ment or not, is at least 100 square inches (see Figure 2.10). This rule applies whether inlet air is brought in through an opening in the compartment door, an opening in the vehicle skirt, through duct
work, or by any other means.
NOTE:
Screening, louvers or expanded metal that cover air openings restrict airflow. You must compen sate for this by making the actual air opening pro portionately larger. See Section 2.3.3 (Page 27).
Figure 2.11 - Suspended Mount: Inlet Door
Using ductwork (Figure 2.12, Page 27). The
installer must be sure air is available to the top of the generator since air inlets are located at the top.

♦ 2.3.4 TESTING THE INSTALLATION

Generac recommends testing the installation to be sure adequate cooling airflow is available to the unit before placing the unit into service. If the unit shows signs of overheating, you will need to enlarge the air openings. Never place a unit into service until absolutely certain that cooling and ventilation is adequate.
NOTE:
You must test the installation, especially if you bring in air from below the generator set.
2.4 GASOLINE FUEL SYSTEH
The installation of a gasoline fuel system (Figure
2.14) for a recreational vehicle generator set must comply with applicable codes, standards and regu lations. The entire fuel system must be completely free of leaks. There must be no possibility of gaso line vapors entering the vehicle interior.
Figure 2.14 - Generator Fuel System

♦ 2.5.3 COMPENSATING FOR RESTRICTIONS

Such materials as screening, louvers or expanded metal can restrict the free flow of air. Compensate for this restriction by making the actual air opening proportionately larger.
Some materials may offer only a 60 percent “free air inlet area.” Other more efficient materials may pro vide up to a 90 percent free air inlet area. The per centage of free air inlet opening is usually available from the material supplier or manufacturer.
To determine the actual air inlet opening size required, divide 100 square inches by the per centage of free air inlet area for the material you will use.
For example: If you plan to use screening with an 80
percent free air inlet area, divide 100 by 0.8, which results in 125 square inches. Minimum actual size of air inlet opening in this case is 125 square inches.

DANGER

Gasoline is highly flammable, and its vapors are explosive. Comply with all codes, standards and
regulations pertaining to gasoline fuel systems used in recreational vehicle generators. Properly install and maintain the fuel system and keep it entirely free of leaks. Gasoline
vapors must not enter the vehicle interior.
Factory installed generator fuel system components include (a) fuel filter, (b) 12-volt DC electric pump, (c) engine carburetor, and (d) interconnecting lines and fittings. Connect a fuel supply line to the fuel filter inlet. Use a flexible length of approved fuel hose between the fuel filter inlet connection and rigid fuel lines.

Series QP55-G Recreational Vehicle Generator

4- 2.4.1 FUEL TANK

Either the generator must share the vehicle engine's fuel tank, or you must install a separate fuel tank for the generator set. All fuel tanks installed on the vehicle must be constructed, installed and restrained so they comply with applic able codes, standards and regulations.
If the generator is to share the vehicle engine's tank, separate fuel pickup tubes are required for the engine and the generator. Generac recommends that you make the fuel pickup tube 2 to 3 inches
(51 to 76 mm) shorter than the vehicle engine's pickup tube. This prevents the generator from depleting the entire fuel supply during prolonged generator operating periods.
-A CAUTION A~
Do not tee the generator fuel supply line into
the vehicle engine fuel supply line. If this is
A
done, the generator will be starved of fuel
when both engines are operating at the same
time. Also, while the vehicle engine is not run
ning, generator operation may drain the vehi cle engine supply line, making it difficult to start the vehicle engine.

♦ 2.4.2 GENERATOR FUEL SUPPLY LINE

2.4.2.1 Rigid Fuel Lines

Those lines used to supply fuel from a tank to the
generator must comply with applicable codes, stan dards and regulations. The following general rules apply to rigid fuel lines:
• Rigid lines should be of annealed, seamless,
drawn aluminum or steel.
• Lines and fittings must comply with SAE J512F,
“Standard Automotive Fittings,” or with ANSI
B 126.26 (latest edition).
• Route the fuel line so that at least 2 inches (51
mm) of clearance is maintained between the line and any exhaust system parts.
the wiring so it cannot come into contact with any fuel line.
• Route fuel lines so if they leak, fuel does not drip onto any electrical or exhaust system parts.
• Use nonferrous metal straps without sharp edges to secure fuel lines.

2.4.2.2 Flexible Fuel Line

Use an approved flexible length of fuel hose between the generator fuel inlet connection and rigid fuel lines. This prevents breaking of the line caused by vibration, shifting, settling or movement.
The following rules apply:
• The flexible hose must comply with SAE J30B, “Standard for Fuel and Oil Hose.” It must be
approved for use with gasoline.
• The hose should be at least 6 inches (152 mm)
longer than is needed to prevent the hose from rupturing if the generator shifts or settles.
2.5 EXHAUST SYSTEIVI
The generator exhaust system must be safely and
properly installed. Only approved mufflers and other exhaust system parts must be used. A prop erly installed exhaust system must be vapor tight, quiet and completely safe.
DANGER
The generator engine gives off 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) vomiting; (c) twitching muscles; (d) throbbing temples; (e) dizziness; (f) headaches; (g) weakness; and (h) sleepiness. IF YOU FEEL ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS PERSIST. GET
MEDICAL HELP. Do not operate the generator until its exhaust system has been inspected and properly repaired.
-------
M CAUTION M.
Never tee the generator engine exhaust pipe
into the vehicle engine exhaust piping. This causes excessive back pressure on the genera tor engine. Also, water from one engine can damage the other engine.

♦ 2.5.1 MUFFLERS AND SPARK ARRESTORS

This muffler meets code and standard require
ments of the U.S. Forest Service. Use only mufflers and parts approved by Generac. Any person(s) installing an unapproved muffler, or an unap
proved exhaust system part, or modifying an
exhaust system in any way that might cause a haz ard, is liable for any damage, injury or warranty expense that might be caused by such unapproved
installation or modification. Failure to provide and maintain a spark arrestor
may be in violation of the law. If this generator is used on any forest covered, brush covered or grass covered unimproved land, you must provide a
spark arrestor. The vehicle owner or operator must maintain this device in good condition. In the state of California, the preceding is required by law
(Section 4442 of the California Public Resources
Code). Other states may have similar laws. Federal laws apply on federal lands.

♦ 2.5.2 TYPE OF EXHAUST SYSTEM

_______________
This generator has a configuration for a side out exhaust system and is equipped with such
an
exhaust muffler (Figure 2.15).
Figure 2.15Exhaust System
Extend the exhaust system at least 1 inch (25 mm) past the outer edge of the vehicle. Do not terminate the exhaust system under the vehicle.
• Terminate the exhaust tailpipe such that exhaust gases will not be drawn back into the generator compartment and recirculated.
• If there is any possibility of the tailpipe or muffler being damaged, protect these damage-prone areas by means of a protective device (such as a skid bar).
• Install the generator exhaust system according to safe automotive practices.
Use enough exhaust system hangers to prevent any part of the system from being dislocated.
Use exhaust system parts recommended by Generac. Using unapproved exhaust mufflers and exhaust system parts is the responsibility of the person(s) installing such unauthorized parts.
• Do not terminate the exhaust system under any opening, window or vent that can be opened or is not permanently sealed from the vehicle Interior.
• Exhaust piping must be large enough to prevent excessive back pressure on the generator engine.
• Never tee the generator engine exhaust pipe into the vehicle engine exhaust piping. This causes excessive back pressure on the generator engine. Also, water from one engine can damage the other engine.
Plan exhaust system installation carefully. Comply with all applicable codes, standards and regulations.

• Maintain a clearance of at least 3 inches (76 mm) between exhaust system parts and any com
bustible material (such as wood, felt, cotton, organic fibers or other like material). If you can not maintain the 3-inch (76 mm) clearance, locate, insulate or shield the exhaust part(s) so that the temperature of any combustible materi al is not raised more than 117° F (65° C) above the ambient air temperature.
2.6 ELECTRICAL CONNECTIONS
Be sure to read Section 1.6 on Page 20. The following general rules apply to electrical con
nections in a recreational vehicle:
Qualified electricians who are familiar with applicable codes, standards and regulations should install electrical wiring.
• The wiring should comply with codes, standards and regulations. The National Electrical Code
(NFPA 70), and state and local codes apply.
• Switches and circuit breakers should be of a type approved for use in recreational vehicles and must be mounted and installed to prevent dam age from road shock.
• Wiring must be of adequate size, have approved insulative qualities and be properly supported.
Conduit and wire openings into the generator compartment (if used) must be vapor-sealed to prevent entry of flammable, explosive or poiso
nous gases into the vehicle.

INSTALLATION
Section 2 - Installation Series QP55-G Recreational Vehicle Generator
• 2.6.1 ELEgRICAL JUNCTION BOX__________________
Install an approved, square electrical junction box
with a blank cover on the interior or exterior wall of
the area you plan to install the generator (NOT on the generator). Route the generator’s AC output leads into this junction box through approved flex ible conduit. This is the point of first termination for generator AC output leads.
• 2.6.2 WIRING
• Wiring should be of stranded copper to reduce the chance that vibration may cause breakage.
® Wire gauge size should be large enough to handle
at least 1 15 percent of the installed generator's rated maximum current.
• If neutral conductors are used, they must be the same size as other leg wires.
Route power supply conductors from generator AC output leads T1 (red). T2 (white), T3 (black) and the green ground wire through approved flexible conduit to the electrical junction box on the compartment wall.
If flexible metal conduit is used between the gener
ator and the compartment junction box, the con duit end that teniiinates the compartment junc tion box must be vapor-sealed. Flexible metal con duit is NOT vapor tight along its entire length.
• From the junction box, route power supply wares through approved conduit to either (a) double-pole, double-throw transfer switch, or (b) approved iso
lation receptacle. Connecting to a transfer switch or isolation receptacle must prevent vehicle electri cal circuits from being connected to two different power supplies at the same time (such as genera tor and dockside power).
Conductors must be rated 221° F (105° C) or must be of a larger conductor size.
• 2.6.3 GENERATOR AC CONNECTIONS
Generator AC output leads T1 (red), T2 (white) and
T3 (black) come out of the generator as shown in
Figure 2.16. Leads T1 (red) and T3 (black) are “hot,”
while T2 (white) is the grounded neutral lead. There
is also a green lead that connects to ground in the
junction box of the recreational vehicle.
_
Figure 2.16 - Generator AC Output Leads
Line T1 (red) to T2 (white) is protected against over load by a 30-amp circuit breaker (CBl). Use this line-to-neutral connection separately to operate
120-volt, single-phase, 60 Hertz, AC loads requiring
up to 3,600 watts (3.6 kW) of power. Line T3 (black)
to T2 (white) also is protected against overload by a 20-amp circuit breaker (CB2). IJse this line-to-neu-
tral connection separately to operate similar loads.
However, be sure the total unit load does not
exceed the maximum rating of the generator. The neutral line (T2, white) on all units is a grounded neutral.
------
Jk CAUTION Ü
Do NOT connect electrical loads in excess of any
A
circuit breaker rating or you will develop prob lems with circuit breaker tripping, which causes a
loss of AC output. Also, do NOT exceed the gen erator's rated wattage capacity. Add the watts or amperes of all lighting, appliance, tool and motor
loads the generator will operate at one time. This total should be less than the unit's rated wattage/amperage capacity.
• 2.6.4 CONDUIT__________________________________
-----------
Route the connections between the generator and the junction box through approved, flexible con duit. The following general rules apply:
• Cut wiring to the required length and allow extra wire for junction box connections.
® Carefully prepare conduit ends to prevent sharp
edges from cutting through wiring insulation.
• Route conduit so it does not interfere with gener ator movement.
• If you use metallic conduit, vapor seal the end of the conduit where it enters the junction box. Do this because flexible metallic conduit is not vaporproof along its entire length.

__________
SOURCES
______________________
________
Connections from the junction box must terminate
in a double-pole, double-throw transfer switch
(Figure 2.17). An alternate method for isolating dif ferent power sources is by using an isolating recep tacle (Figure 2.18). Whichever method you use, you must be certain that both power sources are NOT
connected at the same time.
Figure 2.17 - Transfer Switch Isolation Method

♦ 2.6.6 POWER SUPPLY CORD

The power supply cord must comply with all applic
able codes, standards and regulations. It must be large enough to handle the full amperage to which it will be subjected.

♦ 2.6.7 GROUND FAULT CIRCUIT INTERRUPTERS

The National Electrical Code (NFPA 70. 551-7) requires that you install ground fault circuit inter rupters (GFCIs) on all external and some internal electrical receptacles. Contact your manufacturer or dealer for recommendations.

2.7 BATTERY INSTALLATION
• 2.7.1 RECOMMENDED BATTERY___________________
Install a battery that meets the following requirements:
• The battery must be a 12-volt, automotive type storage battery.
• For prevailing ambient temperatures above 32° F (0° C), use a batteiy rated 70 amp-hours and capable of delivering 400 cold-cranking amperes.
• For prevailing ambient temperatures below 32° F (0° C), use a battery rated 95 amp-hours and
capable of delivering 400 cold-cranking amperes.
NOTE:
If the battery is to be used to power other vehi cle accessories, as well as start the generator, you may need a battery with a larger capacity.
• 2.7.2 BATTERY CABLES
Using batteiy cables that are too long or too small in diameter may cause a drop in voltage, which causes starting problems. For the best cold weather starting, the voltage drop between batteiy terminals and the generator connection point should not exceed 0.12 volts per 100 amperes of cranking current.
These generators are rated at about 100 DC amperes of cranking current.
Select battery cables based on (a) cable length and (b) prevailing ambient temperatures. Generally, the longer the cable and the colder the weather, the larg er the cable size must be, as shown in the chart.
CABLE LENGTH in Feet (meters)
0 to 10 (0 to 3) 2*
11 to 15 (3.4 to 4.5) 0
16 to 20 (4.5 to 6)

The air-cooled generator set was factoiy tested and
adjusted. You should not be required to adjust the unit any further except under special circum stances.
--------

-ik WARNING Mk

Do not make any unnecessary adjustments.
A
Factory settings are correct for most applica
tions. When making adjustments, however, be
careful to avoid overspeeding the engine.
----------------
3.2 BEFORE INITIAL START-UP
Before starting, complete the following;
1. Check the engine crankcase oil level and, if nec essary, fill to the dipstick “FULL” mark (cross­hatched area) with the recommended oil. Do not fill above the FULL mark.
Check the fuel supply. Gas fuel lines must have
2.
been properly purged and leak tested in accor dance with applicable fuel codes. All fuel shut off valves in the fuel supply lines must be open.
DANCER
-A
If a liquid propane (LP) gas fuel system has
A
been installed, it must be 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 gasoline fuel
vapors enter the vehicle interior.
3.3 INITIAL START
When you are absolutely certain that the unit has
been properly Installed and prepared for use, start the engine as follows;
1. Turn off all electrical loads. Do this by setting the generator’s main circuit breakers to their
“OFF” (or open) position.
2. 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 starting since the fuel lines have to be primed (use of the primer switch will shorten this time).
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 Section 3.4. Run the unit at least 30 minutes with loads applied.
6. Turn off all electrical loads by setting the gener ator’s main circuit breakers to their “OFF” (or open) position.
7. Let the unit run at no-load for a few minutes to stabilize internal engine/ -generator tempera tures. Then, shut down the engine.
NOTE:
The generator set was thoroughly tested and
adjusted at the factory before shipping. No addi tional adjustment should be necessary. Only qualified service technicians who have been trained should perform adjustments outlined in this manual.
3.4 TESTING UNDER LOAD
Apply electrical loads equal to about 75 to 100 per
cent 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 airflow is available. You must not allow the unit to overheat during prolonged operation.
NOTE:
The generator engine is equipped with a high temperature switch. The switch has normally closed (N.C.) contacts. When the engine temper ature is too high, switch contacts close, and the engine shuts down automatically.
GENERAC RECOMMENDS THAT YOU TEST THE GENERATOR FOR ADEQUATE COOLING.

CALIFORNIA AND FEDERAL EMISSION CONTROL WARRANTY STATEMENT .

YOUR WARRANTY RIGHTS AND OBLIGATIONS

The California Air Resources Board (CARB) and the United States Environmental Protection Agency (EPA), together with Generac Power Systems, Inc. (Generac), are pleased to explain the Emission Control System Warranty on your new engine.* New utility, and lawn and garden equipment engines must be designed, built and equipped to meet stringent anti-smog standards for the state of California and the federal government. Generac will warrant the emission control system on your engine for the periods of time listed below provided there has been no abuse, neglect, unapproved mod ification or improper maintenance of your engine.
Your emission control system may Include parts such as the carburetor, Ignition and exhaust systems. Generac will repair your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur.

MANUFACTURER'S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:

Emissions control systems on 1997 and later model year engines are warranted for two years as hereinafter noted. If, during such warranty period, any emission-related component or system on your engine is found to be defective in materials or workmanship, repairs or replacement will be performed by a Generac Authorized Warranty Service Facility.

PURCHASER'S/OWNER'S WARRANTY RESPONSIBILITIES:

As the engine purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factoiy supplied Owner’s Manual. For warranty purposes, Generac recommends that you retain all receipts covering maintenance on your engine. However, Generac cannot deny warranty solely because of the lack of receipts or for your failure to ensure the completion of all scheduled maintenance.
As the engine purchaser/owmer, you should, however, be aware that Generac may deny any and/or all warranty cov erage or responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect, improper mainte nance or unapproved modifications, or the use of counterfeit and/or ‘grey market’ parts not made, supplied or approved by Generac.
You are responsible for presenting your engine to a Generac Authorized Warranty Service Facility as soon as a problem occurs. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
Warranty service can be arranged by contacting either your selling dealer or a Generac Authorized Warranty Seiwice Facility. To locate the Generac Authorized Warranty Service Facility nearest you, call our toll-free number:
1-800-333-1322
IMPORTANT NOTE: This warranty statement explains your rights and obligations under the Emission Control System
Warranty (ECS Warranty), which is provided to you by Generac pursuant to California and federal law. See also the
"Generac Limited Warranties for Generac Power Systems, Inc.,” which is enclosed herewith on a separate sheet, also provided to you by Generac. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in terms between the ECS Warranty and the Generac Warranty, the ECS Warranty shall apply except in circumstances where the Generac W'arranty may provide a longer warranty period. Both the ECS Warranty and the
Generac Warranty describe important rights and obligations with respect to your new engine. Warranty service can be performed only by a Generac Authorized Warranty Service Facility. When requesting warranty
service, evidence must be presented showing the date of the sale to the original purchaser/owner. The purchaser/owner shall be responsible for any expenses or other charges incurred for service calls and/or transportation of the product to/from the inspection or repair facilities. The purchaser/owner also shall be responsible for any and/or all damages or losses incurred while the engine is being transported/shipped for inspection or warranty repairs.
If you have any questions regarding your warranty rights and responsibilities, you should contact Generac at
the following address:

EMISSION CONTROL SYSTEM WARRANTY

Emission Control System Warranty (ECS Warranty) for 1997 and later model year engines;
(a) Applicability: This warranty shall apply to 1997 and later model year engines. The ECS Warranty Period shall begin
on the date the new engine or equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue for 24 consecutive months thereafter.
(b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine
or equipment, and to each subsequent purchaser/owner, that each of its engines is ...
(1) Designed, built and equipped so as to conform with all applicable regulations adopted by the EPA and CARS pur
suant to their respective authority, and
(2) Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, may cause a
warranted emlsslons-related part to fail to be identical in all material respects to the part as described in the engine
manufacturer’s application for certification.
(c) The ECS Warranty only pertains to emissions-related parts on your engine, as follows:
(1) Any warranted, emissions-related parts that are not scheduled for replacement as required maintenance in the
Owner’s Manual shall be warranted for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the ECS Warranty shall be warranted for the remainder of the ECS Warranty Period.
(2) Any warranted, emissions-related part that is scheduled only for regular inspection as specified in the Owner’s
Manual shall be warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace as necessary” shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty shall be warranted for the remainder of the ECS Warranty Period.
(3) Any warranted, emissions-related part that is scheduled for replacement as required maintenance in the Owner’s
Manual shall be warranted for the period of time prior to the first scheduled replacement point for that part. If the part falls prior to the first scheduled replacement, the part shall be repaired or replaced by Generac according to Subsection (4) below. Any such emissions-related part repaired or replaced under the ECS Warranty shall be war ranted for the remainder of the ECS Warranty Period prior to the first scheduled replacement point for such emis sions-related part.
(4) Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no
charge to the owner at a Generac Authorized Warranty Service Facility.
(5) "When the engine is inspected by a Generac Authorized Warranty Service Facility, the owner shall not be held respon
sible for diagnostic costs if the repair is deemed warrantable.
(6) Generac shall be liable for damages to other original engine components or approved modifications proximately
caused by a failure under warranty of any emission-related part covered by the ECS Warranty.
(7) Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts suffi
cient to meet the expected demand for such emission-related parts.
(8) Any Generac authorized and approved emission-related replacement part may be used in the performance of any
ECS Warranty maintenance or repairs and will be provided without charge to the purchaser/owner. Such use shall not reduce Generac’s ECS Warranty obligations.
(9) Unapproved, add-on, modified, counterfeit and/or ‘grey market’ parts may not be used to modify or repair a Generac
engine. Such use voids this ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim. Generac shall not be held liable hereunder for failures of any warranted parts of a Generac engine caused by the use of such an unapproved, add-on, modified, counterfeit and/or ‘grey market’ part.
