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 reliably 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 possible cir cumstance 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 recommend, you must satisfy yourself that it is safe for you and others. You also must make sure the procedure, 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 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.

GENERAL HAZARDS

• For safety reasons, Generac recommends that the installation, initial start-up and maintenance of this equipment is carried out by a Generac Authorized Service Dealer.

• The generator engine releases DEADLY carbon monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concentrations, 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 MONOXIDE POISONING ARE (a) inability to think coherently, (b) nausea, (c) vomiting, (d) twitching muscles, (e) throbbing temples, (f) dizziness, (g) headaches, (h) weakness, and (i) sleepiness. IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS 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 installation manual. Make sure there is ample fresh air when operating the genset in a confined area.

• The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous 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 standards. Following installation, you must do nothing 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 ventilating air is critical to correct generator operation 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 provisions, as this can seriously affect safe operation of the generator.

Section 1 – General Information

QUIETPACT 40G Recreational Vehicle Generator

1.2 GENERATOR APPLICABILITY

These generators have been designed and manufactured for supplying electrical power for recreational vehicles. You should not modify the generator or use it for any application other than for what it was designed. If there are any questions pertaining to its application, write or call the factory. Do not use the unit until you have been advised by a competent authority.

For fire safety, the generator must have been 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 instructions. 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 3,600 watts (3.6 kW) of power, but cannot exceed 30 AC amperes of current at 120 volts.

Do not overload the generator. Some installations may require that electrical loads be alternated to avoid overloading. Applying excessively high electrical loads may damage the generator 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 current) for starting than for continuous operation.

1.3 SAFETY

Before attempting to use the generator set, carefully read the “Safety Rules” section of this manual. Comply strictly with these rules to prevent accidents and damage to equipment and/or property. We suggest copying and posting the “Safety Rules” in potential hazard areas of the vehicle. Stress safety to all operators and potential operators of this equipment.

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 two-wire connection system. Note, however, that the neutral is bonded to the frame of the engine-generator.

The generator may have been installed so that it powers 120-volt AC loads (Figure 1.1). It can be wired to connect 120-volt AC electrical loads. This procedure should be done by a Generac Authorized Service Dealer or other qualified installer.

Figure 1.1 – Connections for 120 Volts Only

1.5 SPECIFICATIONS

1.5.1 FUEL REQUIREMENTS

The QUIETPACT series generator is equipped with a gasoline fuel system. Depending on the installation, the generator may have either a separate 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.

NOTE:

Using unleaded gasoline contributes to longer engine valve life by reducing lead and carbon deposits.

Section 2 – Operation

QUIETPACT 40G Recreational Vehicle Generator

2.1 GENERATOR CONTROL PANEL

The following features are mounted on the generator control panel (Figure 2.1):

Figure 2.1 – Generator Control Panel

2.1.1 FUEL PRIMER

Before starting a cold engine (if it has not been started in more than two weeks), you must press this switch for approximately 10 to 15 seconds to bring fuel from the tank to the carburetor. This rocker type switch springs back into its original position when you release it.

2.1.2 START/STOP SWITCH

To crank and start the engine, hold this switch in the START position. Release the switch when the engine starts. To stop an operating engine, press and hold the switch in the STOP position until the engine shuts off. The switch center position is the RUN position.

2.1.3 FUSE

The fuse protects the engine’s DC control circuit against electrical overload. If the fuse element has melted open due to overloading, the engine cannot be cranked. If you must replace the fuse, use only an identical replacement.

2.1.4 MAIN BREAKER

The main breaker protects the generator’s AC output circuit against overload and provides a method of turning OFF the generator’s 120-volt AC output to the vehicle circuits. The QUIETPACT 40G has 30-amp breaker.

2.2 OPTIONAL REMOTE

START/STOP PANEL

A remote mounted Start/Stop Panel is available that allows you to start and stop the generator engine conveniently from inside the vehicle.

You can order model 4057 or 4184, a remote panel that includes a Start/Stop switch, a generator run lamp and an hourmeter. The hourmeter provides a continuous indication of engine/generator operating time. Use the hourmeter for checking off periodic maintenance requirements on the unit.

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 according 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 manufacturer's recommendations.

The engine must have an adequate supply of proper fuel to operate. Before starting it, check that sufficient 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 compartment must be open and unobstructed for continued proper operation. Without sufficient cooling and ventilating airflow, the engine/generator quickly 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.

The generator engine releases DEADLY carbon monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concentrations, 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 MONOXIDE POISONING ARE (a) inability to think coherently, (b) nausea, (c) vomiting, (d) twitching muscles, (e) throbbing temples, (f) dizziness, (g) headaches, (h) weakness, and (i) sleepiness. IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS 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 installation manual. Make sure there is ample fresh air when operating the genset in a confined area.

2.5 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 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:

1. Turn OFF electrical loads using the means pro-

vided in your vehicle (such as a main line circuit 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 started, 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 10 to 15 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.

If the engine does not start after it has been cranking for 15 seconds, release the Start/Stop switch, wait one minute and try again. Holding the switch for longer than 15 seconds can damage the starter motor.

4. Let the engine run at no-load for a few minutes to

stabilize and warm up.

5. Turn ON electrical loads using the means

provided (such as a main circuit breaker or transfer switch).

QUIETPACT 40G Recreational Vehicle Generator

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 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.

2.7.1 LETTING THE ENGINE STABILIZE

The generator supplies correct rated voltage only at the proper governed speed. Some electrical appliances 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 sufficient power is not available may shorten engine life. Never turn ON electrical loads until after the generator engine has started and stabilized at no-load.

2.8 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 connected 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 indi-

cate 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, multiply

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 conditioner, 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.

2.9 PROTECTION SYSTEMS

2.9.1 LOW OIL PRESSURE SWITCH

This switch (Figure 2.2) 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.

2.9.2 HIGH TEMPERATURE SWITCH

This switch (Figure 2.2), which has normally open (N.O.) contacts, is mounted near the oil filter. The contacts close if the temperature should exceed approximately 293º F (145º C), initiating an engine shutdown.

Section 2 – Operation

QUIETPACT 40G Recreational Vehicle Generator

2.9.3 FIELD BOOST

The Controller Circuit Board houses a field boost diode and resistor that are not part of the automatic choke circuit. These two components are part of a “field boost” circuit (Figure 2.3). During engine cranking only, a positive DC (battery) voltage is delivered through the diode, resistor, brushes and slip rings, to the generator rotor. Application of this voltage to the rotor “flashes the field” whenever it is started. Flashing of the field each time the generator starts makes sure that a sufficiently strong magnetic field is available to produce “pickup” voltage in the stator windings.

Figure 2.3 – Field Boost Circuit

2.9.4 OVERVOLTAGE PROTECTION

A solid-state voltage regulator (Figure 2.4) controls the generator’s AC output voltage. This regulator supplies an excitation current to the rotor. By regulating 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, voltage is regulated at 120 volts (voltage-to-frequency ratio is 2-to-1).

Figure 2.4 – Solid State Voltage Regulator

The voltage regulator also incorporates a “voltage surge protection circuit.” This circuit prevents troublesome surges in the generator AC output voltage. Voltage surge is a common cause of damage to electronic equipment.

2.10 ADDITIONAL INFORMATION

2.10.1 25-HOUR BREAK-IN PERIOD

The first 25 hours of operation is the break-in period for the generator. Properly breaking in the generator is essential to minimize fuel consumption and provide maximum engine performance. During this 25hour 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 2.10.2.

2.10.2 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.

2.10.3 ATTENTION REQUIRED AFTER SUBMERSION

If the recreational vehicle generator has been submerged in water, it MUST NOT be started and operated. Following any submersion in water, have a Generac Authorized Service Dealer thoroughly clean and dry the generator.

◆

Generac®Power Systems, Inc. 11

Section 3 – Maintenance

QUIETPACT 40G Recreational Vehicle Generator

2.10.4 OPERATION IN HIGH GRASS OR BRUSH

Never operate the generator while the vehicle is parked over high grass, weeds, brush, leaves or any other combustible substance. Such materials can ignite and burn from the heat of the exhaust system. The generator exhaust system becomes extremely hot during operation and remains hot for a long time after it has shut down.

2.10.5 EFFECTS OF MOISTURE AND DIRT

Keep the generator set as clean and dry as possible. Protect the unit against excessive dust, dirt, corrosive 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 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

For 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 rocker

cover and slowly add oil until it reaches the dipstick “Full” mark. DO NOT FILL ABOVE THE “FULL” MARK.

Never operate the engine with the oil level below the “Add” mark on the dipstick. Doing this could damage the engine.

5. Install and tighten the oil fill cap and the dipstick

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 2.10.1, Page 10). Thereafter, change the oil every 100 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.

2. Immediately after the engine shuts OFF, pull the

oil drain cover free of the base. Remove the plug from the tube with a 5/16” allen wrench and drain the oil into a suitable container. Loosening the oil fill cap will allow the crankcase to drain faster.

3. After the oil has drained, replace the plug onto the

end of the oil drain tube. Retain the cover in the base.

4. With the oil drained, remove the old oil filter by

turning it counterclockwise. Place a towel underneath to catch excess oil.

5. Apply a light coating of clean engine oil to the gas-

ket of the new filter. Fill the filter until saturated with clean oil.

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 oil fill tube and

slowly add the proper type and amount of recommended 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 dipstick

before operating the engine.

10. Start the engine and check for leaks.

NOTE:

Check the oil level and fill to the “FULL” mark after checking for leaks. The filter will retain some oil.

QUIETPACT 40G Recreational Vehicle Generator

3.4 CLEAN AIR INTAKE

Clean all foreign material from the air intake (Figure

3.3) at least once every 100 hours of operation. Clean more often if necessary.

Inspect the area around the generator exhaust muffler periodically and remove all grass, leaves, dirt, etc., from this area.

Figure 3.3 – Cleaning Air Intake

3.5 CHECKING THE ENGINE SPARK PLUG

Clean the spark plug and reset the spark plug gap every 100 hours of operation.

1. Clean the area around the base of the spark plug

to keep dirt and debris out of the engine. Remove the spark plug and check the condition. Replace the spark plug if worn or if reuse is questionable.

2. Clean spark plug by scraping or washing using a

wire brush and commercial solvent. Do not blast the spark plug to clean.

3. Check the spark plug gap using a wire feeler

gauge. Adjust the gap to 0.030 inch (0.76 mm) by carefully bending the ground electrode (Figure 3.4).

Figure 3.4 – Setting the Spark Plug Gap

Sparking can occur if the wire terminal does not fit firmly on the spark plug terminal end. If necessary, re-form the wire terminal to obtain a tight fit.

3.6 FUEL FILTER

Remove and replace the fuel filter (Figure 3.5) once each year or every 400 hours of operation, whichever comes first. Fuel filter is removed with a 15/16” deep well socket.

3.8 CLEANING THE GENERATOR

Do NOT use a forceful spray of water to clean the generator. Water will enter the generator interior and cause problems, and may also contaminate the generator fuel system.

3.9 BATTERY MAINTENANCE

All lead-acid batteries will discharge when not in use. The generator battery should be inspected as follows:

3.9.1 WEEKLY

• Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary.

• Check the battery fluid level of unsealed batteries and, if necessary, fill with Distilled Water Only. Do not use tap water in batteries.

3.9.2 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 batteries and the required precautions. Keep unauthorized personnel away from batteries.

Damage will result if the battery connections are made in reverse.

Do not dispose of the battery in a fire. The battery is capable of exploding. Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery 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 touching the battery by first touching a grounded metal surface.

A battery presents a risk of electrical shock 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.

Do not open or mutilate the battery. Released 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 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 bicarbonate 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.

GENERAL HA

ZARDS

• For safety reasons, Generac recommends

that the installation, initial start-up and maintenance of this equipment is carried out by a Generac Authorized Service Dealer.

• The engine exhaust fumes contain carbon monox-

ide, which can be DEADLY. This dangerous 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 standards. Following installation, you must do nothing 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 venti-

lating air is critical to correct generator operation 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 provisions, 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 genera-

tor, 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 leakage, oil leakage, etc.

• Never insert any tool or other object through open-

ings in the generator interior, even if the unit is not running. You might seriously injure yourself or damage the equipment.

Safety Rules

QUIETPACT 40G Recreational Vehicle Generator

DANGER: For fire safety, installation of a generator into a recreational vehicle must comply strictly with article 551, NFPA 70; ANSI C1-1975; AND, ANSI A119.2-1975/NFPA 501C “Standard for Recreational Vehicles” (Part 3, “Installation of Electrical Systems”). In addition, installation must comply with the manufacturer’s instructions and recommendations.

DANGER

Generac®Power Systems, Inc. 19

ELECTRICAL HAZARDS

• 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 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.

• If the vehicle electrical circuits can be powered by any other source of electricity (such as a “dockside” power receptacle), there must be no possibility of connecting the different power sources to the vehicle circuits at the same time. The dockside (utility) power source must be positively isolated from the vehicle circuits whenever the generator 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 dockside (utility) power workers due to backfeed of electrical energy.

• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving components causing injury.

FIRE HAZARDS

EXPLOSION HAZARDS

• 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.

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 difficult to reinforce.

Many recreational vehicles have been factory equipped with an area for the generator set. Some vehicles may even have a generator compartment provided by the vehicle manufacturer.

Plan the generator location based on the following:

• The generator set must be installed on a framework 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 frequently serviced components, such as filters, oil drains, spark plugs and other common maintenance 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 compartment walls and ceiling, the minimum recommended applies to the space between the generator 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 framework. The following general rules apply:

• Vehicle construction MUST be capable of supporting the weight of the generator.

• Whether the generator is mounted above the horizontal 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, consider using additional tubing, angle brackets or other supports to give the supporting frame sufficient strength.

Figure 2.1 – Typical Horizontal Support Frame

2.1.3 SUSPENDED MOUNTING

If you are going to suspend the generator below the horizontal support tubing, the suspension method you use with the vehicle frame members must (a) be able to support the weight of the generator AND (b) provide sufficient restraint for the generator. One typical suspended mounting system is shown in Figure

2.2. The location of a suspended mounting system

must be carefully planned, keeping the following general rules in mind:

• Protect the generator against road splash and debris. Baffles or splash guards may be required to protect certain areas of the generator. To make sure the generator is adequately protected, road test the installation through mud, water and slush.

Figure 2.2 – Typical Suspended Mounting System

• The installer must make certain that the selected location will permit adequate cooling and ventilating airflow to be supplied.

Generac®Power Systems, Inc. 23

2.1.4 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 supporting 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.

Figure 2.3 – Typical Generator Restraint

2.2 GENERATOR COMPARTMENTS

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 minimum clearance of 1/2 inch (13 mm) on the front and top, 1/2 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).

NOTE:

Refer to “Figure 1.2 – Major Features and Dimensions” on Page 21.

Figure 2.4 – Clearances

2.2.2 COMPARTMENT CONSTRUCTION

• The generator compartment should be either constructed of, or lined with, 26-gauge galvanized steel.

NOTE:

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 constructed of 1/2-inch thick plywood (not strandboard), with the floor made of a double thickness of 1/2-inch plywood with the grain of the wood at cross section for added strength (Figure 2.5).

Figure 2.5 – Typical Compartment Construction

• 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 material 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 conduit, 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 construction, 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, riveted or screwed. Manufactured lock seams are shown in Figure 2.6. Installer constructed compartments typically utilize a standard lap joint.

Figure 2.6 – Types of Lock Seams

• 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 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 compartment is properly constructed and metal lined, they can add acoustical material. This may include additional sealant or insulating material, to reflect noise away from the vehicle interior.

Sound insulating materials should be of a nonflammable type. One excellent insulating material is a 1inch (25 mm) thick fiberglass having a 2-pound density. When fiberglass is used, its coated side should face toward the compartment interior.

Do not install sound insulation or any 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 single material. For example, a sheet of lead or visco-elastic material, along with a layer of other acoustical material, is more effective than when a single material is used.

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 ventilating air into or out of the compartment.

In addition to the effective use of sound insulating materials, construction of a special noise abatement compartment might be considered to reduce noise levels. Such a compartment might be constructed 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 combination of acoustical materials as mentioned in Section 2.2.3.

To prevent fire or explosion, do not install any 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 insulation (such as 1-inch (25 mm) thick fiberglass with a 2pound density).

2.3 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 difficulties 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.

Never use discharged cooling air for heating or permit such air to enter the vehicle interior. This air contains deadly carbon monoxide gas and other poisonous, flammable 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 bottom right side of the generator (Figure 2.9). This airflow cools the engine/generator and electronic components. The second part of the cooling system, a suction fan, draws air that is heated from a hot engine into a collector compartment at the left side of the unit. This heated air (although cooler than exhaust muffler) is then deflected out the bottom toward the ground.

Figure 2.9 – Airflow Through Engine/Generator

2.3.2 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 SYSTEM

The installation of a gasoline fuel system (Figure

2.10) for a recreational vehicle generator set must comply with applicable codes, standards and regulations. The entire fuel system must be completely free of leaks. There must be no possibility of gasoline vapors entering the vehicle interior.

Figure 2.10 – Generator Fuel System

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.

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 applicable 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.

Do NOT tee the generator fuel supply line into the vehicle engine fuel supply line. If this is done, the generator will be starved of fuel when both engines are operating at the same time. Also, while the vehicle engine is not running, generator operation may drain the vehicle 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, standards 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 B126.26 (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.

• Do not attach electrical wiring to fuel lines. Route 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 SYSTEM

The generator exhaust system must be safely and properly installed. Only approved mufflers and other exhaust system parts must be used. A properly installed exhaust system must be vapor tight, quiet and completely safe.

The generator engine gives off DEADLY carbon monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concentrations, 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 MONOXIDE POISONING ARE (a) inability to think coherently; (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.

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.

2.5.1 SPARK ARRESTOR

This spark arrestor assembly meets code and standard requirements of the U.S. Forest Service. Use only mufflers and parts approved by Generac. Any person(s) installing an unapproved muffler, or an unapproved exhaust system part, or modifying an exhaust system in any way that might cause a hazard, 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.

When installing/replacing the tailpipe or spark arrestor components, verify that the tailpipe has a hole to securely fasten the spark arrestor components (see Figures 2.11 and 2.12). Use only Generac supplied hardware. Substitution of parts may cause damage to the screen or a loose fit to the tailpipe.

Figure 2.11 - Spark Arrestor

Figure 2.12 — Spark Arrestor Installation

2.5.2 EXHAUST SYSTEM SAFETY

• Maintain a clearance of at least 3 inches (76 mm) between exhaust system parts and any combustible material (such as wood, felt, cotton, organic fibers or other like material). If you cannot maintain the 3-inch (76 mm) clearance, locate, insulate or shield the exhaust part(s) so that the temperature of any combustible material is not raised more than 117° F (65° C) above the ambient air temperature.

• 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.

2.6 ELECTRICAL CONNECTIONS

Be sure to read Section 1.6 on Page 20.

The following general rules apply to electrical connections 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 damage 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 poisonous gases into the vehicle.

2.6.1 ELECTRICAL 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 flexible 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 115 percent of the installed generator's rated maximum current.

• Neutral conductors must be the same size as other leg wires.

• Route power supply conductors from generator AC output leads (white), (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 conduit end that terminates the compartment junction box must be vapor-sealed. Flexible metal conduit is NOT vapor tight along its entire length.

• From the junction box, route power supply wires through approved conduit to either (a) doublepole, double-throw transfer switch, or (b) approved isolation receptacle. Connecting to a transfer switch or isolation receptacle must prevent vehicle electrical circuits from being connected to two different power supplies at the same time (such as generator 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 (BLACK) “hot” and (WHITE) grounded neutral come out of the generator as shown in Figure 2.13. There is also a green lead that connects to ground in the junction box of the recreational vehicle.

Figure 2.13 – Generator AC Output Leads

Leads BLACK to WHITE are protected against overload by a 30-amp circuit breaker (CB1). Use this lineto-neutral connection separately to operate 120-volt, single-phase, 60 Hertz, AC loads requiring up to 3,600 watts (3.6 kW) of power.

Do NOT connect electrical loads in excess of any circuit breaker rating or you will develop problems with circuit breaker tripping, which causes a loss of AC output. Also, do NOT exceed the generator'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 conduit. 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 generator 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.

The National Electrical Code (NFPA 70, 551-7) requires that you install ground fault circuit interrupters (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 battery 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 vehicle accessories, as well as start the generator, you may need a battery with a larger capacity.

2.7.2 BATTERY CABLES

Using battery 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 battery terminals and the generator connection point should not exceed 0.12 volts per 100 amperes of cranking current.

PRIMEPACT 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 larger the cable size must be, as shown in the chart.

2.7.3 BATTERY CABLE CONNECTIONS

1. Connect the battery cable from the battery post or

terminal indicated by a POSITIVE, POS or (+) to the lug on the starter contactor (Figure 2.16).

NOTE:

Check to be sure the battery cable boot for the starter cable has been installed.

2. Connect the battery cable from the battery post

indicated by a NEGATIVE, NEG or (-) to the frame ground connection (Figure 2.16).

3. Connect cables so the connectors are clean

and tight.

Figure 2.16 – Connecting Battery Cables

2.7.4 BATTERY COMPARTMENT

Install the generator battery in its own, vented compartment. Place the battery compartment away from any source of heat, sparks or flame.

Provide ventilation openings in the battery compartment. The minimum size of openings should be 2 square inches at the top of the compartment. Mount the battery on a strong, rigid supporting structure, where leaks and spills of battery fluid will not cause damage.

2.8 OPTIONAL ACCESSORIES

A plug-in receptacle (Figure 2.17) is provided on the generator set. Use this receptacle to connect an optional remote-mounted start/stop panel to the generator. Installation of such a panel will permit you to start and stop the generator engine from any convenient location inside the vehicle.

2.8.1 REMOTE START/STOP PANEL

A remote mounted Start/Stop panel (Figure 2.18) is available that allows the user to start and stop the generator engine conveniently from inside the vehicle. The remote panel includes a Start/Stop switch, hourmeter, generator run lamp and a wire harness. The hourmeter should be used in conjunction with the maintenance operations found in Part I of this manual.

Figure 2.18 – Optional Remote Panel

3.1 POST INSTALLATION TESTS

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

Do not make any unnecessary adjustments. Factory settings are correct for most applications. 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.

2. Check the fuel supply. Gas fuel lines must have

been properly purged and leak tested in accordance with applicable fuel codes. All fuel shutoff valves in the fuel supply lines must be open.

If a liquid propane (LP) gas fuel system has been installed, it must be properly tested for leaks before operating the system in compliance 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 generator’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 temperatures. Then, shut down the engine.

NOTE:

The generator set was thoroughly tested and adjusted at the factory before shipping. No additional 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 percent 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 temperature 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 modification 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 factory 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/owner, you should, however, be aware that Generac may deny any and/or all warranty coverage or responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect, improper maintenance 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 Service 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 Warranty 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 CARB pursuant

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 war-

ranted emissions-related part to fail to be identical in all material respects to the part as described in the engine manufacturer’s application for certification.

(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 fails 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 warranted for the remainder of the ECS Warranty Period prior to the first scheduled replacement point for such emissions-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 responsi-

ble 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 sufficient

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.

EMISSION RELATED PARTS INCLUDE THE FOLLOWING:

*Generac engine types covered by this warranty statement include the following:

1) Utility

2) Lawn and Garden Equipment

3) Recreational Vehicle (RV) Generator

THIS WARRANTY SHALL NOT APPLY TO THE FOLLOWING:

• Costs of normal maintenance, adjustments, installation and start-up.

• Failures caused by any contaminated fuels or oils.

• Failures due, but not limited, to normal wear and tear, accident, misuse, abuse, negligence or improper installation. As

with all mechanical devices, the GN-Series engines need periodic part(s) service and replacement to perform well. This warranty will not cover repair when normal use has exhausted the life of a part(s) or engine.

• Failures caused by any external cause or act of God, such as collision, theft, vandalism, riot or wars, nuclear holocaust, fire, freezing, lightning, earthquake, windstorm, hail, volcanic eruption, water or flood, tornado or hurricane.

THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED. SPECIFICALLY, GENERAC MAKES NO OTHER WARRANTIES AS TO THE MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.

GENERAC’S ONLY LIABILITY SHALL BE THE REPAIR OR REPLACEMENT OF PART(S) AS STATED ABOVE. IN NO EVENT SHALL GENERAC BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH DAMAGES ARE A DIRECT RESULT OF GENERAC’S NEGLIGENCE. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation may not apply to you. Purchaser/owner agrees to make no claims against Generac based on negligence.

This warranty gives you specific legal rights. You also may have other rights that vary from state to state.
