GENERAL HAZARDS



• For safety reasons, the manufacturer recommends that the installation, initial startup, and maintenance of this equipment be performed by an Authorized Service Dealer.



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 EXPERIENCING 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. Thus, the exhaust system must be installed properly, in strict compliance with applicable codes and standards. Following installation, 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 seriously damages the generator. Do not alter the installation or permit even partial blockage of ventilation provisions, as this can also seriously affect the safe operation of the generator.

Section 1 – General Information

Recreational Vehicle Generator

1.2 GENERATOR APPLICABILITY

These generators have been designed and manufactured for supplying electrical power to recreational vehicles. DO NOT modify the generator nor 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 advised by a competent authority.

For fire safety, the generator must have been



properly installed in compliance with NFPA 70 (latest edition), “National Electrical Code”, Article 551, and NFPA 1192 (latest edition), “Standard for Recreational Vehicles”. 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.

Use this generator to supply electrical power for operating 120/240-volt, single-phase, 60-Hertz, AC electrical loads. These loads can require up to 8,500 watts (8.5 kW) of power, but cannot exceed 70.8 AC amps of current at 120 volts, or 35.4 AC amps at 240 volts.

DANGER

1.4 GENERATOR AC CONNECTION SYSTEM

This generator 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 generator may have been installed so that it powers 120-volt AC electrical loads only (Figure 1.1). It can be rewired to connect 120/240-volt AC electrical loads. This procedure should be done by an Authorized Service Dealer or other qualified installer. Refer to the installation portion of this manual for more information.

Figure 1.1 – Connections for 120 Volts Only —

Dual Circuits

Do not overload the generator. Some installa-



tions may require that electrical loads be alternated to avoid overloading. Applying excessively high electrical loads may damage the generator and 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.

1.5 SPECIFICATIONS

1.5.1 FUEL REQUIREMENTS 

The generator is equipped with a diesel fuel system. Use clean, fresh No. 1D or No. 2D diesel fuel with minimum Cetane number of 40. The diesel fuel must also conform to American Society of Testing and Materials (ASTM) specifications. Never use any dirty or contaminated fuel. When adding fuel, DO NOT overfill the tank. Allow room at the top of the tank for fuel expansion. Depending on the installation, the generator may have either a separate fuel tank or “share” the vehicle’s engine fuel tank.

Page 8

Section 1 – General Information

Recreational Vehicle Generator

NOTE:

Some installations using a “shared” fuel tank may have a generator fuel pickup tube that is shorter than the vehicle’s engine pickup tube. Such an arrangement causes the generator engine to “run out of fuel”, while adequate fuel for the vehicle engine remains in the tank.

Also, appropriate care should be taken in applications where extremely low ambient temperatures are possible, to ensure the temperature of the diesel fuel is not allowed to fall below levels where “gelling” could occur.

1.5.2 FUEL CONSUMPTION (GAL/HR) 

Model No Load Half Load Full Load

005432-0 0.28 0.49 0.78

1.5.3 ENGINE OIL REQUIREMENTS 

Use a high-quality detergent oil with American Petroleum Institute (API) classification “For Service CC.” Detergent oils keep the engine cleaner and reduce carbon deposits. Use oil having the following SAE viscosity rating, based on the ambient temperature range anticipated before the next oil change:

Temperature Oil Grade (Recommended)

Above 100° F (38° C) SAE 15W-40* or SAE 40

40° to 100° F (4.4° to 38° C) SAE 10W-30 or SAE 30

Below 40° F (4.4° C) SAE 5W-20 or 5W-30

* - in units from the factory

Crankcase and oil filter capacity is approximately

4.35L or 4.6 U.S. quarts. Do NOT use special additives. See "Checking the Engine Oil Level" and "Changing the Engine Oil and/or Filter" sections for oil level checking and changing procedures.

1.5.4 COOLANT 

Use a 50:50 mixture that is half low silicate, ethylene glycol base antifreeze and half soft water. Use only soft water and only low silicate antifreeze. If desired, a high-quality rust inhibitor to the recommended coolant mixture may be added. When adding coolant, always add the recommended 50-50 mixture.

Ethylene glycol base antifreeze is poisonous.



Do not use mouth to siphon coolant from the radiator, recovery bottle, or any container. Wash hands thoroughly after handling. Never store used antifreeze in an open container because animals are attracted to the smell and taste of antifreeze, even though it is poisonous to them.

Do not use any chromate base rust inhibitor



with ethylene glycol base antifreeze; or else, chromium hydroxide (“green slime”) will form and cause overheating. Engines that have been operated with a chromate base rust inhibitor must be chemically cleaned before adding ethylene glycol base antifreeze. Using any highsilicate antifreeze boosters or additives will also cause overheating. DO NOT use any soluble oil inhibitor for this equipment.

cranking for 15 seconds, release the Start/Stop switch, wait 15 seconds, 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 in the vehicle (such as, a main-line circuit breaker or transfer switch).

2.5 STOPPING THE GENERATOR

1. Turn OFF all electrical loads, using the means provided in the vehicle (such as, a main-line circuit breaker or transfer switch).

2. Let the generator run at no-load for a few minutes, to stabilize internal engine generator temperatures.

Do not stop the engine/generator immediately



after running under load. This can overheat and damage the engine and/or generator.

3. Press and hold the Start/Stop switch in the STOP position, until the engine shuts off.

2.6 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.

2.6.1 LETTING THE ENGINE STABILIZE 

The generator supplies correctly rated voltage only at the proper governed speed. Some electrical appliances may be extremely sensitive to voltage. Incorrect voltages can damage such appliances.

Electrical loads applied on the engine 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.

2.6.2 DO NOT OVERLOAD THE GENERATOR 

Read the rated wattage/amperage capacity of the generator on the generator data label located below the user control panel.

Applying electrical loads in excess of the unit’s rated capacity may trip the line breaker or cause the engine/generator to 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

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, multiply

that load’s rated VOLTS times AMPS to obtain WATTS.

Page 12

Section 2 – Operation

Recreational Vehicle Generator

• 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, calculate 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.

• For the first two or three hours of operation, do not apply electrical loads over 75 percent of the unit’s rating.

2.7 PROTECTION SYSTEMS

The engine has several safety switches that cause it to automatically shut down, under the following conditions: low oil pressure, high coolant temperature, and engine overspeed. See Figure 2.2 for the location of these devices. If automatic shutdown does occur, refer to “Troubleshooting Guide”.

2.7.1 LOW OIL PRESSURE SWITCH 

This switch is normally closed (N.C.) but is held open by engine oil pressure during engine running. Should operating oil pressure drop below approximately 10 psi, the switch contacts close, and the engine shuts down automatically.

2.7.3 OVERSPEED SHUTDOWN 

A DC control circuit board senses engine speed from the frequency of the alternator AC output. Should the alternator output frequency exceed approximately 72 Hertz (4,320 alternator rpm), circuit board action initiates an automatic engine shutdown.

2.7.4 OVERVOLTAGE PROTECTION 

A solid-state voltage regulator (Figure 2.3) 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 2.3 – Solid-state Voltage Regulator

2.7.2 HIGH COOLANT TEMPERATURE 

SWITCH

This normally-open (N.O.) thermostatic switch has a sensing tip that is immersed in captive coolant. Should the coolant temperature exceed approximately 115° C (240° F), the switch contacts close, and the engine shuts down automatically.

Figure 2.2 – Engine Protective Devices

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.

2.8 ADDITIONAL INFORMATION

2.8.1 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 an Authorized Service Dealer thoroughly clean and dry the generator.

Page 13

Section 3 – Maintenance

Recreational Vehicle Generator

2.8.2 OPERATION IN HIGH GRASS  OR BRUSH

Never operate the generator while the vehicle is parked over high grass, weeds, brush, leaves, or 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.

2.8.3 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 reduces insulation resistance and will eventually cause problems. Dirt will make the problem worse, since it tends to hold moisture in contact with windings. Salt (as from sea air) will also 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

Check the engine crankcase oil level every eight hours of operation, or at least once daily, before using the generator. For oil capacities and requirements, see “Engine Oil Requirements”. To check the engine oil level, proceed as follows (see Figure 3.1):

1. Be sure the generator is as leveled as possible.

2. Remove the dipstick, and wipe it dry with a clean,

lint-free cloth.

3. Install the dipstick, and fully seat the T-handle;

then, remove it again. The oil level should be at the dipstick “Full” mark.

4. If necessary, remove the oil fill plug 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 the oil-fill plug and the dipstick before

operating the engine.

3.2 CHANGING THE ENGINE OIL AND/OR OIL FILTER

Never operate the engine with the oil level



below the “ADD” mark on the dipstick. Doing this could damage the engine.

Change the engine oil and oil filter after the first 25 hours of operation. See the “Service Schedule” section for subsequent oil and filter changes. Change the oil more frequently, if operating consistently under heavy load or at high ambient temperatures.

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 (for

at least five minutes) then shut OFF the engine.

2. Immediately after the engine shuts OFF, remove

the front service door, located beneath the unit, by retracting the two latches and pivoting the door downward. If space allows, remove the front panel by removing the four retaining bolts. Be careful not to let the panel fall.

3. Remove the air filter (see "Servicing the Engine

Air Filter").

4. Remove the oil-drain plug and drain the oil into a

suitable container. Removing the oil-fill plug will allow the crankcase to drain faster.

5. After the oil has drained, replace the oil-drain

plug. Go to step 9 if changing oil only.

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

turning it counterclockwise.

7. Apply a light coating of clean engine oil to the

gasket of the new filter.

8. 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.

9. Remove the dipstick, and wipe it dry with a clean, lint-free cloth. This will be used later to check the oil level.

10. Remove the oil-fill plug, and slowly add the proper type and amount of recommended oil (see "Engine Oil Requirements"). 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.

11. Install the oil-fill plug and the dipstick.

12. Reinstall the air filter.

13. Reattach the front service door or front panel; make sure the latches are fully engaged and the bolts are fully tightened.

14. 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.

3.3 SERVICING THE ENGINE

3.4 SPARK ARRESTOR MUFFLER

The exhaust muffler supplied with the generator is a spark arrestor type. The exhaust mufflers for recreational vehicle generators do not have a spark arrestor screen, but are of the more efficient “toroid” or “swirl” type. To remove carbon and combustion deposits from the muffler, proceed as follows (see Figure 3.3):

1. Place the unit above a noncombustible surface, and ensure that the generator exhaust piping is cool.

2. Remove the two screws holding the spark arrestor access plate to the rear floor pan.

3. Remove the spark arrestor access plate and gasket.

4. Remove the hex pipe cap from the end of the spark arrestor cleanout pipe.

5. Thread on a 3/8” NPT pipe coupling and pipe nipple to extend the cleanout pipe at least 10 inches (250 mm) below the rear floor pan; additional piping may be added to direct the muffler exhaust away from the cooling air discharge flow beneath the unit.

Figure 3.3 – Spark Arrestor Muffler Maintenance

AIR FILTER

To access the engine air filter (Figure 3.2), remove the front service door, located beneath the unit, by retracting the two latches and pivoting the door downward. Loosen the hose clamp at the base of the air filter and remove the filter. Place the hose clamp on the new filter and install it, making sure it is positioned properly before reattaching the service door. Make sure the service door latches are fully engaged.

Figure 3.2 – Engine Air Filter

See the “Service Schedule” for recommended air cleaner maintenance.

REMOVABLE FRONT PANEL TRANSPARENT FOR VIEWING PURPOSES.

6. Start and run the engine for approximately 15 minutes.

7. Shut down the engine, and allow the piping to cool.

8. Remove the 3/8” NPT coupling and piping.

9. Apply a graphite-base, anti-seize compound to the cleanout pipe threads.

10. Reinstall the hex pipe cap, spark arrestor access plate, gasket, and two screws.

The exhaust system of this product gets



extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc., must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system.

Page 15

Failure to provide and maintain a spark arres-



tor may be in violation of the law. If this generator is used on any forest-covered, brushcovered, or grass-covered unimproved land, the vehicle owner or operator must maintain the spark arrestor 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.

Be sure to reinstall the hex pipe cap tightly to



the spark arrestor cleanout pipe. Vibration could cause a loose cap to fall out, resulting in hot engine exhaust being drawn through the centrifugal cooling fan and out beneath the unit. This could result in damage to the generator or in discharge of hot exhaust sparks beneath the unit.

3.5 CLEANING THE GENERATOR

Keep the generator as clean and as dry as possible. Dirt and moisture that accumulate on internal generator windings have adversely affect insulation resistance.

Periodically, clean the generator’s exterior surfaces. A soft brush may be used to loosen caked-on dirt. Use a vacuum system or dry, low-pressure air to remove any accumulations of dirt. The generator is housed inside an all-weather enclosure; clean the enclosure with a soft, damp cloth or with sponge and water.

Once each year, have the generator cleaned and inspected by an Authorized Service Dealer. Service technicians will use dry, low-pressure air to clean internal windings. Parts inside the control console should be cleaned and inspected at this time, as well.

Finally, have the insulation resistance of stator and rotor windings checked. If insulation resistances are excessively low, the generator may require drying.

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.

Section 3 – Maintenance

Recreational Vehicle Generator

3.6 BATTERY MAINTENANCE

All lead-acid batteries will discharge when not in use. The generator battery should be inspected per the “Service Schedule”. The following procedure should be used for inspection:

• 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.

• Have the state of charge and condition checked by

an Authorized Service Dealer.

NOTE:

Servicing of the battery is to be performed or supervised by knowledgeable personnel, according to the required precautions. Keep unauthorized 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



battery is capable of exploding. Storage batteries release 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 tool or equipment near the battery. Discharge static electricity from 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, and 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 connect-

ing, 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.

Page 16

Section 3 – Maintenance

DANGER

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;

• Immediately wash with water all skin areas that come into contact with the electrolyte.

• If the electrolyte contacts the eyes, immediately flush eyes thoroughly with water, and seek medical attention.

• 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) of 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.

3.7 COOLING SYSTEM

Air intake and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. Avoid obstructions, such as, high grass, weeds, brush, leaves, and snow.

Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down.

3.8 ENGINE COOLANT

Check the coolant level in the coolant recovery tank at least once daily or prior to use. Add the recommended coolant mixture (see "Coolant"), as necessary; the tank should be kept within the levels indicated on the adjacent decal. If desired, a high-quality rust inhibitor to the recommended 50-50 coolant mixture may be added. If added consistently, the recommended mixture will protect the unit against freezing temperatures.

Periodically remove the radiator pressure cap, located behind the access cover above the user control panel, to make sure the coolant recovery system is functioning properly. Coolant should be at the bottom of the radiator filler neck. If the coolant level is low, inspect the gasket in the radiator pressure cap. Replace the cap, if necessary. To have the pressure cap tested, contact an Authorized Service Dealer. Inspect both the cooling system and coolant recovery system for leaks.

Do not remove the radiator pressure cap while



the engine is hot; otherwise, serious burns from boiling liquid or steam could result.

Ethylene glycol base antifreeze is poisonous.



Do not use any chromate base rust inhibitor



with ethylene glycol base antifreeze; otherwise, chromium hydroxide (“green slime”) will form and cause overheating. Engines that have been operated with a chromate base rust inhibitor must be chemically cleaned before adding ethylene glycol base antifreeze. Using any highsilicate antifreeze boosters or additives will also cause overheating. DO NOT use any soluble oil inhibitor for this equipment.

3.9 MAJOR SERVICE MANUAL

To obtain a service manual for the generator, the nearest Authorized Service Dealer. Make sure to identify the MODEL NUMBER and SERIES.

3.10 DRIVE BELT

The engine drives the generator rotor by means of a pulley and drive belt arrangement. Drive belt tension was properly adjusted before the unit was shipped from the factory. If suspect that drive belt tension is incorrect, contact an Authorized Service Dealer.

3.11 EXERCISING THE GENERATOR

At least once every seven days, start and operate the generator. Let the unit run for at least 30 minutes to “exercise” the engine. If the generator cannot be exercised every seven days, and it is to be out of service longer than 30 days, see "Out-of-Service Procedure".

Despite the safe design of this generator,



Parts of the generator are rotating and/or hot



during operation. Exercise care near running generators.

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.

GENERAL HAZARDS



• For safety reasons, the manufacturer recommends that the installation, initial startup, and maintenance of this equipment is carried out by an Authorized Service Dealer.

• 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, 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.

• When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.

• 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 openings in the generator interior, even if the unit is not running. Serious injury or damage to the equipment could be done.

ELECTRICAL HAZARDS



• The generator covered by this manual produces dangerous electrical voltages that 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 work must be done 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 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’s circuits at the same time. The dockside (utility) power source must be positively isolated from the vehicle’s circuits whenever the generator is operating. Failure to isolate the vehicle’s circuits from the dockside power supply when the generator is running may result in damage to the generator or in serious injury or death to dockside (utility) power workers due to backfeed of electrical energy.

• In case of an 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 nonconducting implement, such as, a rope or board, to free the victim from the live conductor. If the victim is unconscious, apply first aid, and get immediate medical help.

• 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



• 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 established. 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 noncompliance with the aforementioned codes, standards, 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 system. Keep the extinguisher properly charged, and be familiar with its use. If there are any questions pertaining to fire extinguishers, consult the local fire department.

EXPLOSION HAZARDS



• Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no combustible materials are left in the generator compartment, or on or near the generator, as FIRE or EXPLOSION may result. Keep the area surrounding the generator clean and free from debris.

• All fuel types are potentially FLAMMABLE and/or EXPLOSIVE and should be handled with care. Comply with all laws regulating the storage and handling of fuels.

• Fuel supply lines must be properly installed, purged and leak-tested according to applicable fuel-gas codes, before placing this equipment into service. There must be no possibility of fuel vapors entering the vehicle interior.

• It is required that an approved, flexible, nonconductive fuel line between the generator fuel connection point and the rigid fuel lines be installed.

Recreational Vehicle Generator

2.1 LOCATION AND SUPPORT

Be sure the installation complies with all standards and codes listed in the "Standards Booklets" section of this manual.

2.1.1 GENERATOR LOCATION 

The most desirable location for the generator set is between the vehicle's main frame members.

Many recreational vehicles have been factoryequipped with an area for the generator set. Some 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 the "Generator Support" section.

• 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, and other common maintenance parts.

• The location must provide sufficient room to allow minimum clearances for air circulation. If sound insulation is to be used on the compartment walls and ceiling, the minimum recommended clearance 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.

• 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.

2.1.3 SUSPENDED MOUNTING 

If the generator will be suspended below the horizontal support tubing, the suspension method used 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 2.1. 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 2.1 – Typical Suspended Mounting System

2.1.2 GENERATOR SUPPORT 

The generator must be securely attached to a metal framework that has been affixed to 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.

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.

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

Page 25

Section 2 – Installation

Recreational Vehicle Generator

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 2.2). All bolts must be long enough so that, when tight, they engage at least 3/8” of an inch [9.5 millimeters]. Refer to the "Generator Compartments" section for the location of the generator mounting holes.

Figure 2.2 – Typical Generator Restraint

Figure 2.3 – Typical Compartment Construction

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 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. The manufacturer 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, having the grain of the wood at cross section for added strength (Figure 2.3).

• 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 materials such 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 a 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.

Page 26

Section 2 – Installation

Recreational Vehicle Generator

• 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 2.4. Installer-constructed compartments typically utilize a standard lap joint.

Figure 2.4 – 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 the "Sound Insulating Materials" section.

DANGER

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. Use approved, nonflammable insulating materials in high temperature areas.

2.2.2 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.

DANGER

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.

2.2.3 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 2.5):

• 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’s 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 the "Sound Insulating Materials" section.

DANGER

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 2-pound density).

Figure 2.6 – Compartment Floor Cutout

2.2.4 COMPARTMENT FLOOR CUTOUTS 

Provide openings in the generator compartment for the following items (Figure 2.6):

• Engine exhaust and cooling air outlets

• Generator cooling air inlet and front service door

• Four holes for passage of generator mounting bolts. See the "Generator Restraint" section.

• Rear service door.

DANGER

Fuel lines and exhaust piping must not pen-



etrate into the vehicle living area.

Page 28

Section 2 – Installation

Recreational Vehicle Generator

2.3 COOLING AND VENTILATING AIR

It is absolutely essential that an adequate flow of air for cooling, ventilation, 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 a path for exhausting the cooling air to the exterior of a compartment, if so equipped.

DANGER

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 

This unit uses an impellar fan located on the alternator drive pulley to cool the alternator’s internal components. Air is drawn through the alternator and expelled radially behind the drive pulley. An enginedriven centrifugal blower draws in cooling air through air inlet openings, moves that air around the engine/ generator and across the radiator, then discharges that air out the bottom (see Figure 2.7).

2.3.2 COOLING AIR INLET OPENINGS 

The minimum size of the air inlet opening, whether the generator is housed in a conventional compartment or not, is at least 150 square inches (975 cm2) (see Figure 2.8). 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. Compensate for this by making the actual air opening proportionately larger. See the "Compensating for Restrictions" section.

Figure 2.8 – Air Inlet in Compartment Door

Figure 2.7 – Airflow Through Engine/Generator

When the unit is installed on a suspended mounting system, one of several different methods of supplying airflow may be used as follows:

• Provide a door in the vehicle skirt having an air inlet opening (Figure 2.9).

Figure 2.9 – Suspended Mount: Inlet Door

• Use duct work (Figure 2.10). The installer must be sure air is available to the sides of the generator for proper air intake.

• Provide an opening in the vehicle skirt and space around the generator for cooling airflow (Figure

2.11). Recommended clearance around all sides of the generator is at least two inches (50 mm).

Page 29

Section 2 – Installation

Recreational Vehicle Generator

Figure 2.10 – Air Inlet Using Duct work

Figure 2.11 – Air Inlet in Vehicle Skirt

2.3.4 TESTING THE INSTALLATION 

The manufacturer 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, enlarge the air openings. Never place a unit into service until absolutely certain that cooling and ventilation is adequate.

NOTE:

The installation must be tested, especially if bringing in air from below the generator set.

2.4 DIESEL FUEL SYSTEM

The installation of a diesel fuel system (Figure 2.12) 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 fuel vapors entering the vehicle interior.

Figure 2.12 – Generator Fuel System

2.3.3 COMPENSATING FOR RESTRICTIONS 

Materials, such 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 provide up to a 90 percent free air inlet area. The percentage of free air inlet opening is usually available from the material’s supplier or manufacturer.

To determine the actual air inlet opening size required, divide 150 square inches (975 cm2) by the percentage of free air inlet area for the material being used.

For example: If planning to use screening with an 80

percent free air inlet area, divide 150 (975) by 0.8, which results in 187.5 square inches (1,218.75 cm2). Minimum actual size of air inlet opening in this case is 187.5 square inches (1,218.75 cm2).

DANGER

All fuel types are potentially FLAMMABLE and/



or EXPLOSIVE and should be handled with care. Comply with all laws regulating the storage and handling of fuels. Properly install and maintain the fuel system, and keep it entirely free of leaks. Fuel vapors must not enter the vehicle interior.

Page 30

Section 2 – Installation

Recreational Vehicle Generator

Because diesel fuels are less volatile than gasoline or gaseous fuels, they are considered safer from the standpoint of storage and handling. As a result, installers may tend to be careless in their installation practices, which can result in poor engine performance. For example, a poorly tightened fuel line may not show any signs of leakage; however, air can be drawn into the loose connection and cause problems. Air that is trapped in the diesel fuel system results in hard starting and rough engine operation.

Dirt that enters the fuel system also may cause problems. Lines and piping must be properly installed and tightened to prevent dirt from entering. Diesel fuel must be kept clean.

Factory-installed generator fuel system components include (a) a fuel filter, (b) a 12-volt DC electric pump, (c) an injection pump, and (d) interconnecting lines and fittings. Connect a fuel supply line to the supply fitting and a return line from the fuel return fitting back to the tank.

NOTE:

Fuel supply and return fittings located on the generator are 1/8” NPT.

Use a length of approved flexible fuel hose between the fuel connection fittings and rigid fuel lines (see the Generator Fuel Supply Lines" and "Generator Fuel Return Lines" sections.

2.4.1 FUEL TANK 

Either the generator must share the vehicle’s engine fuel tank, or a separate fuel tank for the generator set must be installed. 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’s engine tank, separate fuel pickup tubes are required for the engine and the generator. The manufacturer recommends that the fuel pickup tube be two to three inches (51 to 76 mm) shorter than the vehicle’s engine 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 LINES 

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 that, 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.

• Fuel system components must be accessible, but protected from abrasion, chafing, road damage, and kinking.

2.4.2.2 Flexible Fuel Line 

Use a length of approved flexible fuel hose between the generator fuel supply fitting 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 J1137 (30R7), “Standard for Fuel and Oil Hose.” It must be approved for use with diesel fuel and low permeability.

• 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.

2.4.3 GENERATOR FUEL RETURN LINES 

The same general rules that apply to fuel supply lines also apply to fuel return lines.

NOTE:

Locate the diesel fuel return line at least 12 inches from the tank fuel pickup tubes to prevent air bubbles from entering the fuel supply lines.

Section 2 – Installation

Recreational Vehicle Generator

2.5 EXHAUST SYSTEM

The generator exhaust system must be safely and properly installed. Only approved exhaust system parts must be used. A properly 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 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 FEELING 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.

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 the 3-inch (76 mm) clearance cannot be maintained, locate, insulate, or shield the exhaust part(s) so that the temperature of any combustible material is not raised to more than 117° F (65° C) above the ambient air temperature.

• Terminate the exhaust tailpipe at least 3 feet (91 cm) from the vehicle’s fuel filler cap and at least 2 inches (51 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.

• Fuel and oil must NOT be able to drip onto any exhaust system part.

Figure 2.13 – Typical Exhaust System

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 MUFFLER AND SPARK ARRESTOR 

The exhaust muffler supplied with this unit is a spark arrestor type that meets code and standard requirements of the U.S. Forest Service. 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.

• 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.

Page 32

Section 2 – Installation

Recreational Vehicle Generator

• Use exhaust system parts recommended by the manufacturer. 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 the "Generator AC Connection System" section.

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 planed for installation of 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.

• 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 a flexible metal conduit is used between the

generator and the compartment junction box, the conduit end that terminates at 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) double-pole, 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.

When connecting vehicle load leads, the following rules apply:

• Connect 120-volt, single-phase, 60-Hertz, AC electrical loads, requiring up to the trip rating of circuit breaker CB1, across AC output leads T1 (red) and T2 (white).

• Connect 120-volt, single-phase, 60-Hertz, AC electrical loads, requiring up to the trip rating of circuit breaker CB1A, across AC output leads T3 (black) and T2 (white).

• Try to keep the load balanced between the two circuit breakers and the stator windings.

• The neutral line (T2, white) on all units is a grounded neutral.

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 2.14. 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.

These generators use a four-position terminal block to connect between stator power leads and vehicle load leads. This terminal block is accessible by removing the access panel, shown in Figure 2.14. Units are shipped from the factory connected for dual-circuits (120 volts AC) output (See Figure 2.15). Two stator power windings are used, with each winding capable of supplying half of the unit's rated wattage/amperage capacity. The circuit from each winding is protected against overload by a line breaker (CB1 and CB1A). Line breakers CB1 and CB1A have a trip rating of 40 amps.

2.6.3.1 Generator Conversion to  120/240 Volt Dual Voltage

NOTE:

Conversion of this generator from "120 volts only, dual circuits" to "120/240 volt - dual circuits" (or vice-versa) requires rerouting wires within the unit enclosure. It is recommended that this conversion be performed by an Authorized Service Dealer.

Figure 2.16 shows the stator power winding con-

circuit breaker rating, or problems will develop 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 amps 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.

Figure 2.15 – Connections for 120 Volts Only —

nections for 120/240 volt dual voltage. The stator power windings are connected in series. Lead 11/11A connects to T1 (Red), lead 44/44A connects to T3 (Black), while leads 22 and 33 are grounded and connect to T2 NEUTRAL (White). A "tie bar" connects the two switch handles on line breaker CB1.

To convert from "120 volt dual circuits" to "120/240 volt dual voltage", disconnect battery power from the generator and reverse stator lead wires 33 and 44 as follows:

NOTE:

It is necessary to feed stator lead wires 33 and 44 through grommets on the electrical enclosure and engine control box in order to perform the rerouting outlined below. The front and top unit enclosure panels, as well as the user control panel, must be removed to perform this. After re-routing, wires

Figure 2.16 – Connections for 120/240 Dual

Voltage

should be properly tied down to prevent chafing or contact with moving internal components

1. Remove stator lead wire 44, as shown in Figure

2.15, from the ground stud adjacent to the four-

position terminal block. Reroute stator lead 33 from the line side terminal of CB1A (renamed as CB1 in Figure 2.16) to the ground stud location previously occupied by stator lead wire 44.

2. Move smaller gauge (#18 AWG) wire labeled #11 (not shown), from the top of CB1 to the top of CB1A. Renumber this wire #44.

3. Reroute stator lead wire 44, removed in step 1, to the line side terminal on CB1.

Recreational Vehicle Generator

2.6.4 CONDUIT 

Route the connections between the generator and the junction box through approved, flexible conduit. The following general rules apply:

• All wiring, conduit, and interconnections must

be installed in compliance with applicable codes, standards, and regulations.

• 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 genera-

tor movement.

• If using metallic conduit, vapor-seal the end of the

conduit where it enters the junction box. Do this because flexible metallic conduit is not vapor proof along its entire length.

• All openings in the generator compartment for the

passage of wiring and conduit must be sealed and made vapor-tight.

NOTE:

Use a high-quality silicone rubber base sealant or other approved method (such as, explosion-proof fittings) to seal such openings.

2.6.5 POWER SUPPLY CORD 

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

2.6.6 GROUND FAULT CIRCUIT  INTERRUPTERS

The National Electrical Code (NFPA 70, 551-7) requires that ground-fault circuit interrupters (GFCIs) be installed on all external and some internal electrical receptacles. Contact the manufacturer or dealer for recommendations.

2.6.7 ISOLATING DIFFERENT POWER  SOURCES

Connections from the junction box must terminate in a double-pole, double-throw transfer switch (Figure

2.17). An alternate method for isolating different power sources includes using an isolating receptacle (Figure 2.18). Whichever method is used, be certain that both power sources are NOT connected at the same time.

Figure 2.17 – Transfer Switch Isolation Method

Page 35

Section 2 – Installation

Recreational Vehicle Generator

Figure 2.18 – Installation With Isolation Receptacle

DANGER

 If the vehicle’s 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’s circuits at the same time. The dockside (utility) power source must be positively isolated from the vehicle’s circuits whenever the generator is operating. Failure to isolate the vehicle’s circuits from the dockside power supply when the generator is running may result in damage to the generator or in serious injury or death to dockside (utility) power workers due to backfeed of electrical energy. Installation and connection of the generator must comply with NFPA 70, Article 551, and NFPA 1192 (latest editions).

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.

• Use a battery with minimum ratings of 70 amphours and 600 cold-cranking amps.

NOTE:

If the battery is to be used to power other vehicle accessories, as well as to start the generator, a battery with a larger capacity may be necessary.

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 amps of cranking current.

The generator is rated at about 160 DC amps of cranking current to operate the starter and glow plugs.

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.

CABLE LENGTH in Feet (meters) CABLE SIZE

0 to 10 (0 to 3) 2*

11 to 15 (3.4 to 4.5) 0

16 to 20 (4.5 to 6) 000

*For warm weather, use No. 2 cable up to 20 feet.

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 insulated lug on the unit frame (Figure

2.19).

NOTE:

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

Recreational Vehicle Generator

2. Connect the battery cable from the battery post, indicated by a NEGATIVE, NEG, or (-), to the vehicle frame ground connection (Figure 2.19).

3. Connect a cable from the vehicle frame ground to the negative post on the generator frame.

4. Connect cables so the connectors are clean and tight.

Figure 2.19 – 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.

DANGER

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 tool or equipment near the battery. Discharge static electricity from 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 is 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.

• If the electrolyte contacts the eyes, immediately flush eyes thoroughly with water, and seek medical attention.

2.8 OPTIONAL ACCESSORIES

A plug-in connector (Figure 2.20) is provided on the generator set, below the control panel. Use this to connect an optional remote-mounted start/stop panel to the generator. Installation of such a panel will permit starting and stopping the generator engine from any convenient location inside the vehicle.

2.8.1 REMOTE START/STOP CONNECTIONS 

The following steps are necessary to connect the remote start/stop option:

1. If the six-wire remote connector is visible below the control panel, as shown in Figure 2.20, skip to step 5. Otherwise, proceed with step 2.

2. Remove the electrical access panel located just below the knock-out labeled “REMOTE.” The remote connector will be located inside the electrical enclosure, along the right side.

3. Remove the “REMOTE” knock-out, taking care not to damage the wiring behind it.

4. Feed the remote connector through the hole, and fit the supplied grommet into position.

5. Wire the remote harness (Part # 0D2021C, supplied as an accessory with the generator) to the vehicle’s remote start panel. Refer to Figure 2.20 for a wiring legend.

6. Plug the remote harness into the mating remote connector on the generator.

3.1 POST INSTALLATION TESTS

The generator set was factory-tested and adjusted. It is not necessary 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 STARTUP

Before starting, complete the following:

1. Check the engine crankcase oil level and, if necessary, fill to the dipstick “FULL” mark (crosshatched area) with the recommended oil. Do not fill above the FULL mark.

2. Check the fuel supply. 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.

3.3 INITIAL START

When 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 line breakers to their “OFF” (or open) position.

2. Refer to Part I, the “Starting the Generator” section, 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 preheat switch will operate the generator’s electrical fuel pump and 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 the "Testing Under Load" section. Run the unit at least 30 minutes, with loads applied.

6. Turn off all electrical loads by setting the generator’s line 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.

The generator set was thoroughly tested and



adjusted at the factory before shipping. No additional adjustment should be necessary. Only trained, qualified service technicians should perform adjustments outlined in this manual.

3.4 TESTING UNDER LOAD

Apply electrical loads equal to about 50 to 75 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. Do not allow the unit to overheat during prolonged operation.

NOTE:

The generator engine is equipped with a high coolant temperature switch. The switch has normally open (N.O.) contacts. When the engine coolant temperature is too high, switch contacts close, and the engine shuts down automatically.

THE MANUFACTURER RECOMMENDS THAT THE GENERATOR BE TESTED FOR ADEQUATE COOLING.

Section 7 – Warranty

Recreational Vehicle Generator

FEDERAL AND CALIFORNIA EMISSIONS CONTROL WARRANTY STATEMENT

(for non-road Diesel engines rated under 19 kW)

YOUR WARRANTY RIGHTS AND OBLIGATIONS

The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), Generac Power Systems, Inc. (GENERAC), and the engine manufacturer for this equipment, Ishikawajima Shibaura Machinery Co., Ltd. (ISM), are pleased to explain the federal and California emission control system warranty on your engine.

In California, new 2000 and later small non-road engines must be designed, built, and equipped to meet the state's stringent anti-smog standards. In other states, new 2000 and later non-road diesel engines rated under 19 kW must be designed, built, and equipped to conform to applicable EPA regulations.

ISM must warrant the emission control system on your engine for that period of time listed below, provided there has been no abuse, neglect, or improper maintenance of your small non-road diesel engine.

Your California and EPA emission control system may include parts, such as, the fuel injection system and other emissionrelated assemblies.

Where a warrantable condition exists, GENERAC will repair your engine at no cost to you, including diagnosis, parts, and labor, on behalf of ISM. Although ISM is ultimately responsible for this warranty, GENERAC has agreed to carry out ISM's warranty repair responsibilities, and GENERAC should be your primary contact for emission-related warranty service.

MANUFACTURER'S WARRANTY COVERAGE

For 2000 and later small non-road diesel engines, first sold in California, and for 2000 and later non-road diesel engines rated under 19 kW, first sold in all other states, the applicable warranty period is two (2) years or 1,500 hours, whichever comes first.

If any emission-related part on your engine is defective, the part will be repaired or replaced by a Generac Authorized Warranty Service Facility on behalf of ISM.

PARTS COVERED

This emission control system warranty applies to the following engine emission control parts.

• Fuel Injection Pump • Fuel Injectors

• Intake Manifold • Exhaust Manifold

• Air Cleaner Element • Miscellaneous Hoses, Bolts and Connectors

OWNER'S WARRANTY RESPONSIBILITIES

As the engine owner, you are responsible for the performance of the required maintenance listed in your Owner's Manual. GENERAC and ISM recommend that you retain the original purchase documentation and all receipts covering maintenance on your engine, but GENERAC and ISM cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

As the engine owner, you should be aware, however, that GENERAC and ISM may deny you warranty coverage if your engine or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications.

You are responsible for contacting 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

If you have any questions regarding your warranty rights and responsibilities, you should contact GENERAC at the following address:

Section 7 – Warranty

Recreational Vehicle Generator

OBLIGATIONS AND RIGHTS OF THE MANUFACTURER AND OWNER

The new model year, class of diesel engine, and emission application determination for your engine are identified on the emission control information label affixed to the right-hand side of your engine's timing gear case. The warranty period begins on the date the new equipment is sold to the first retail purchaser.

Any emission control system parts scheduled for regular inspection that are proven defective during normal use will be repaired or replaced during the warranty period. Any warranted part that is scheduled for replacement, and that fails prior to replacement, will be repaired or replaced under warranty, and the repaired or replaced part will be covered under warranty for the remainder of the period prior to the first scheduled replacement. The warranty repairs and service will be performed by any Generac Authorized Warranty Service Facility, with no charge for parts or labor (including diagnosis).

As the engine owner, you are responsible to perform all the required maintenance listed in your Owner's Manual. GENERAC will not deny an emission warranty claim solely because you have no record of maintenance; however, a claim may be denied if your failure to perform maintenance resulted in the failure of a warranted part. Receipts covering regular maintenance should be retained in the event of questions, and these receipts should be passed on to each subsequent owner of the engine.

It is recommended that replacement parts used for maintenance or repairs be GENERAC authorized and approved parts, to maintain the quality originally designed into your emission-certified engine. However, any replacement part may be used in the performance of any warranty maintenance or repairs and must be provided without charge to the owner. Such use will not reduce the warranty obligations of GENERAC. Add-on or modified parts may not be used for maintenance or warranty repairs. Such use will be grounds for disallowing a warranty claim, and GENERAC will not be liable to warrant failures of warranted parts caused by the use of an add-on or modified part.

LIMITATIONS

This warranty shall not cover any of the following:

(a) Systems and parts that were not first installed on the new equipment or engine as original equipment by GENERAC.

(b) Conditions resulting from tampering, misuse, abuse, improper adjustment, engine alteration, use of add-on or modified

parts, use of replacement parts that are not the same in performance and durability as GENERAC-approved replacement parts, accident, failure to use the recommended fuel or oil, use of unapproved fuel or oil additives, or failure to perform required maintenance.

(d) Consequential damages, such as, loss of time, inconvenience, or loss of use of this engine or equipment.

(e) Damages or repair costs caused by the owner's unreasonable delay in making the engine available for inspection

and repair.

(f) Diagnosis or inspection fees that do not result in eligible warranty service being performed.

(g) Equipment with an altered or disconnected hourmeter, where the hours cannot be determined.

(h) Equipment normally operated outside the United States.

(i) Accident-caused damage, acts of nature, or other events beyond GENERAC’S control.

(j) Warranty repairs undertaken or attempted by the owner or any other person who is not affiliated with a Generac Authorized

Warranty Service Facility.

OBTAINING WARRANTY SERVICE

To obtain service under this warranty, promptly contact your nearest Generac Authorized Service Dealer or a Generac Authorized Warranty Service Facility. If available, provide the GENERAC representative with the original purchase receipt (showing the initial date of purchase) and all available maintenance records.

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.

You also have other rights from state to state.
