SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation



be copied and posted in potential hazard areas of the recreational vehicle. Safety should be stressed to all operators and potential operators of this equipment.



The engine exhaust from this product

• contains chemicals known to the state

defects or other reproductive harm.



This product contains or emits chemicals

• known to the state of California to cause

cancer, birth defects or other reproductive harm.

Study these SAFETY RULES carefully before installing, operating or servicing this equipment. Become familiar with this manual and with the unit. The generator can operate safely, efficiently and reliably only if it is properly installed, operated and maintained. Many accidents are caused by failing to follow simple and fundamental rules or precautions.

The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed to the unit, are, therefore, not all-inclusive. If using a procedure, work method or operating technique the manufacturer does not specifically recommend, ensurethat it is safe for others. Also make sure the procedure, work method or operating technique utlized does not render the generator unsafe.

WARNING:•

of California to cause cancer, birth

WARNING:•

DANGER

Despite the safe design of this generator, operat-



ing 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, the manufacturer recommends

• that the installation, initial start-up and maintenance of this equipment is carried out by an 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 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 run-

• ning 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 mon-

• oxide, 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 ven-

tilating 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.

•

Inspect the generator regularly, and contact the

nearest Authorized Service Dealer immediately for parts needing repair or replacement.

•

Before performing any maintenance on the gen-

erator, disconnect its battery cables to prevent accidental start up. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG or (–) first. Reconnect that cable last.

•

Never use the generator or any of its parts as a

step. Stepping on the unit can stress and break parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage, oil leakage, etc.

ELECTRICAL HAZARDS



The generator covered by this manual produces

• dangerous electrical voltages and can cause fatal electrical shock. Avoid contact with bare wires, terminals, connections, etc., while the unit is running. Ensure all appropriate covers, guards and barriers are in place before operating the generator. If 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, have the

• generator properly grounded (bonded) either by solid mounting to the vehicle frame or chassis, or by means of an approved bonding conductor. DO NOT disconnect the bonding conductor, if so equipped. DO NOT reconnect the bonding 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.

In case of accident caused by electric shock, imme-

• diately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT



Safety Rules

Recreational Vehicle Generator

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 equip-

ment. 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.

Gasoline is extremely FLAMMABLE and its vapors

• are EXPLOSIVE. Do not permit smoking, open flame, sparks or any source of heat in the vicinity while handling gasoline. Comply with all laws governing the storage and handling of gasoline.

This generator may use liquid propane (LP) gas

• as a fuel. LP gas is highly EXPLOSIVE. The gas is heavier than air and tends to settle in low areas where even the slightest spark can ignite the gas and cause an explosion.

Section 1 – General Information

Recreational Vehicle Generator

1.2 GENERATOR APPLICABILITY

These generators have been designed and manufactured for supplying electrical power for recreational vehicles. Do 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 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.

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 4,800 watts (4.8 kW) of power, but cannot exceed 40 AC amperes of current at 120 volts, or 20 AC amperes at 240 volts for model 02010-2. For model 04164-3, the loads can require up to 4,500 watts (4.5 kW) of power, but cannot exceed 37.5 amperes of current at 120 volts, or 18.8 amperes at 240 volts.

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 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.

DANGER

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 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 loads (Figure 1.1). It can be wired to connect both 120- and/or 240-volt AC electrical loads. This procedure should be done by an Authorized Service Dealer or other qualified installer.

Figure 1.1 – Connections for 120 Volts Only

1.5 SPECIFICATIONS

1.5.1 FUEL REQUIREMENTS



This 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 1 – General Information

Recreational Vehicle Generator

The manufacturer does not recommend using



any gasoline containing alcohol (such as “gasohol”). If using any gasoline containing alcohol, it must not contain more than 10 percent ethanol, and it must be removed from the generator during storage. Do NOT use any gasoline containing methanol. If using gasoline with alcohol, inspect more frequently for fuel leaks and other abnormalities.

1.5.2 OPTIONAL PROPANE FUEL SYSTEM



This generator is equipped with a liquid propane (LP) gas fuel system. LP gas is usually supplied as a liquid in pressure tanks.

The generator requires a vapor withdrawal type fuel system. This type of gaseous fuel system uses the vapors forming above the liquid fuel in the storage tank. Air temperature around the storage tank must be high enough to sustain adequate fuel vaporization. In colder climates, it may be necessary to use an independent heat source to be sure the fuel sufficiently vaporizes in the storage tank.

LP gas may consist of propane, butane or a mixture of the two gases. Propane vaporizes at temperatures as low as -20° F (-29° C), but butane returns to its liquid state when the temperature drops below about 32° F (0° C). For that reason, a higher ratio of propane is desired in the gas mixture when temperatures drop below freezing.



1.5.3 FUEL CONSUMPTION

Model No Load 1/2 Load Full Load

02010-2 0.32 0.46 0.76 04164-3 0.47/17.05 0.72/3.06 1.25/45.35

Gasoline is in gal/h. LP is in gal/h and cf/h.

1.5.4 ENGINE OIL REQUIREMENTS



Use only high quality detergent oil rated with American Petroleum Institute (API) Service Classification SF, SG or SH. The recommended oil weights include the following:

During summer months: SAE 30. An acceptable

• substitute is SAE 10W-30.

During winter months: SAE 5W-30. DO NOT USE

• SAE 10-W40.

Crankcase and oil filter capacity is approximately 1,400 mL or 1.5 U.S. quarts. Do NOT use special additives. See "Checking the Engine Oil Level" and "Changing the Engine Oil and/or Oil Filter" sections for oil level check and fill procedures.

Section 2 – Operation

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), this switch must be pressed 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 released. It is not necessary to press the primer switch for LP units.

NOTE:

If the generator has been reconnected for dual voltage AC output (120/240 volts), install line breakers having an amperage rating that is different than that stated in the "Generator AC Connection System" section. The replacement line breakers consist of two separate breakers (one 20 amp, and one 30 amp) with a connecting piece between the breaker handles (so that both breakers will operate at the same time). If the unit is reconnected for dual voltage, it is no longer RVIA listed.

2.2 OPTIONAL REMOTE

START/STOP PANEL

A remote mounted Start/Stop Panel (Figure 2.2) is available that allows starting and stopping the generator engine conveniently from inside the vehicle. The remote panel includes a Start/Stop switch, hourmeter, generator run lamp and a wire harness.

Figure 2.2 — Optional Remote Panel

(Models 004057 and 004184)

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 the fuse must be replaxed, 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 120/240-volt AC output to the vehicle circuits. The generator has one 20-amp breaker and one 30-amp breaker.

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.

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.

DANGER

Any attempt to crank or start the engine before



it hase been properly serviced with the recommended oil may result in an engine failure.



2.4.3 FUEL SUPPLY

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.

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 the vehicle (such as a main line circuit breaker or transfer switch).

Section 2 – Operation

Recreational Vehicle Generator

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 the engine has not been started 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 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).

2.8 SUMMER/WINTER HEAT RISER SYSTEM

Under certain weather conditions, it is possible for ice to form in the venturi area of the carburetor. This condition can be very dangerous because it can prevent the governor system from functioning properly, which results in a “runaway” engine.

The most common weather conditions leading to this problem are temperatures in the range of 25° F to 35° F (-4° C to 1.7° C), along with high humidity. This ice formation also can be attributed to the load being applied during these weather conditions. Generators running with no-load or light loads applied usually have the most problems.

The Summer/Winter Lever (Figure 2.3) should be in the WINTER position for ambient temperatures below 40° F (4.4° C) and in the SUMMER position for ambient temperatures above 40° F (4.4° C).

Figure 2.3 – Heat Riser System

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.

When the heat riser is in the SUMMER (down) position (Figure 2.2), air is drawn into the air cleaner from the upper intake tube.

When the heat riser is in the WINTER (up) position, air is drawn from the lower intake tube, which is positioned to draw the heated air near the exhaust manifold.

To prevent carburetor icing, the owner/operator should physically position the heat riser to the proper position dependent on the temperature.

Section 2 – Operation

Recreational Vehicle Generator

2.8.1 DO NOT OVERLOAD THE GENERATOR



Read the rated wattage/amperage capacity of the generator on the generator data decal (see "Generator Identification").

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

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.

•

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

Figure 2.4 – Low Oil Pressure and

High Temperature Switches

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 2.5). During engine cranking only, a positive DC (battery) voltage is delivered through the diode, resistor, brushes and slip rings, and the generator rotor. Application of this voltage to the rotor “flashes the field” 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.

2.9. LOW OIL PRESSURE SWITCH



This switch (Figure 2.4) 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 2.4), 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.

Figure 2.5 – Field Boost Circuit

2.9.4 OVERVOLTAGE PROTECTION



A solid-state voltage regulator (Figure 2.6) 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 2.6 – 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 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.



2.10.2 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.

Section 3 – Maintenance

Recreational Vehicle Generator

2.10.3 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 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 section “Engine Oil Requirements”. Check the engine crankcase oil level at least every eight hours of operation, or before use. 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.

Section 3 – Maintenance

Recreational Vehicle Generator

3.2 CHANGING THE ENGINE OIL AND/OR OIL FILTER

Change the engine oil after the first 25 hours of

•

operation. 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 fol-

•

lows (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 hose free of its retaining clip. Remove the cap from the hose and drain the oil into a suitable container. Loosening the oil fill cap will allow the crankcase to drain faster.

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

end of the oil drain hose. Retain the hose in the clip.

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

turning it counterclockwise.

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

gasket of the new filter.

6. Screw the new filter on by hand until its gasket

lightly contacts the oil filter adapter. Then, tighten the filter an additional 3/4 to one turn.

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

lint-free cloth. This will be used later to check the oil level.

8. Remove the oil fill cap on the rocker cover and slowly add the proper type and amount of recommended oil (see section "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.

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.

1. Follow steps 1-3 in the "Cleaning the Foam Precleaner" section; service the foam precleaner if necessary.

2. Remove the paper filter.

3. Clean the air filter by tapping it gently on a solid surface. If the filter is too dirty, replace it with a new one. Dispose of the old filter properly.

4. Clean the air cleaner cover then reassemble following steps 7-9 in the "Cleaning the Foam Precleaner" section.

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. Clean by scraping or washing using a wire brush and commercial solvent. Do not blast the spark plug to clean.

2. Remove the spark plug and check the condition.

Replace the spark plug if worn or if reuse is questionable.

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).

 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.

Figure 3.4 – Setting the Spark Plug Gap

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.

Section 3 – Maintenance

Recreational Vehicle Generator

3.6 FUEL FILTER (GASOLINE ONLY)

Remove and replace the fuel filter (Figure 3.5) once each year or every 100 hours of operation, whichever comes first.

Figure 3.5 – Fuel Filter

Fuel Filter

3.7 SPARK ARRESTOR MUFFLER

If the generator is not equipped with a spark arrestor exhaust muffler and is to be used on any forest covered, brush covered or grass covered unimproved land, a spark arrestor may need to be installed. The spark arrestor must be maintained in effective working order by the vehicle owner/operator.

For assistance in ordering, installing and maintaining spark arrestor exhaust mufflers, contact the nearest Authorized Service Dealer.

Exhaust mufflers supplied by the manufacturer are spark arrestor types. The manufacturer's 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 such mufflers, remove the plug from the muffler and run the engine for approximately 15 minutes. Shut down the engine, let the muffler cool and install the plug.

Be sure to reinstall the muffler plug tightly.



Engine vibration could cause a loose plug to fall out. Without the plug in place, hot engine exhaust is directed out the opening. This hot exhaust, depending on the installation, could be directed to areas not able to withstand the extreme heat such as wooden floor boards or other flammable material. This could result in a fire.

3.8 CLEANING THE GENERATOR

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.

Section 3 – Maintenance

Recreational Vehicle Generator

DANGER

Do not dispose of the battery in a fire. The bat-



tery 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 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.

Recreational Vehicle Generator

2.1 LOCATION AND SUPPORT

2.1.1 GENERATOR LOCATION



The most desirable location for the generator set is between the vehicle's main frame members. However, this is seldom possible. Most units must be installed on the side of the vehicle and are 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 frame-

• work 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 fre-

• quently 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 the "Generator Compartment" section. 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 support-

• ing the weight of the generator.

•

Whether the generator is mounted above the hori-

zontal 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 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 2.2. 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.

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 the "Generator Compartment" section for the location of the generator mounting holes.

Figure 2.3 – Typical Generator Restraint

Section 2 – Installation

Recreational Vehicle Generator

2.2.2 COMPARTMENT CONSTRUCTION



The generator compartment should be either con-

• structed 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 with the grain of the wood at cross section for added strength (Figure 2.5).

Figure 2.5 – 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 SIZE

Plan the compartment size carefully. Provide a minimum clearance of 1/2 inch (13 mm) on the front, 11/2 inches (38 mm) on the top, and 1 inch (25 mm) on the sides and 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”.

Figure 2.4 – Clearances

If constructing a compartment, line the exterior

• (underside) of the compartment floor with 26gauge galvanized steel.

All seams, splices and joints of the compart-

• ment 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.

Section 2 – Installation

Recreational Vehicle Generator

•

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.

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.

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 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.

2.2.3 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.

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 com-

•

partment.

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 thick-

•

ness 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 combina-

•

tion 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 2pound density).

Section 2 – Installation

2.2.5 COMPARTMENT FLOOR CUTOUTS



Provide openings in the generator compartment for the following items (Figure 2.8):

Engine exhaust and cooling air outlets

• Generator cooling air inlet

• Four holes for passage of generator mounting bolts.

•

See the "Generator Restraint" section.

DANGER

Fuel lines and exhaust piping must not penetrate



into the vehicle living area.

Section 2 – Installation

Recreational Vehicle Generator

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.

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



Engine operation drives cooling fans for the two-stage cooling air system. A pressure fan draws cooling air into the top of the generator (Figure 2.9). This airflow cools the 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 pan at the base 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

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 2.10 – Air Inlet in Compartment Door

NOTE:

Be sure to meet the minimum clearances illustrated in Figure 2.4.

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 2.11).

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 100 square inches (see Figure 2.10). This rule applies whether inlet air is brought in through an opening in the compartment door, an opening in the vehicle skirt, through ductwork, or by any other means.

Figure 2.11 – Suspended Mount: Inlet Door

Using ductwork (Figure 2.12). The installer must

•

be sure air is available to the top of the generator since air inlets are located at the top.

By providing an opening in the vehicle skirt and

•

space behind the generator for cooling airflow (Figure 2.13). Recommended clearance behind the back of the generator is at least 1/2 inch (13 mm).

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 air is brought in from below the generator set.

2.4 GASOLINE FUEL SYSTEM

The installation of a gasoline fuel system (Figure

2.14) 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.

2.3.3 COMPENSATING FOR RESTRICTIONS



Such materials as screening, louvers or expanded metal can restrict the free flow of air. Compensate for this restriction by making the actual air opening proportionately larger.

Some materials may offer only a 60 percent “free air inlet area.” Other more efficient materials may provide up to a 90 percent free air inlet area. The percentage of free air inlet opening is usually available from the material supplier or manufacturer.

To determine the actual air inlet opening size required, divide 100 square inches by the 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 100 by 0.8, which results in 125 square inches. Minimum actual size of air inlet opening in this case is 125 square inches.

FUEL FILTERFUEL PUMP

DANGER

Gasoline is highly flammable, and its vapors are



explosive. Comply with all codes, standards and regulations pertaining to gasoline fuel systems used in recreational vehicle generators. Properly install and maintain the fuel system and keep it entirely free of leaks. Gasoline vapors must not enter the vehicle interior.

Factory installed generator fuel system components include (a) fuel filter, (b) 12-volt DC electric pump, (c) engine carburetor, and (d) interconnecting lines and fittings. Connect a fuel supply line to the fuel filter inlet. Use a flexible length of approved fuel hose between the fuel filter inlet connection and rigid fuel lines.

Section 2 – Installation

Recreational Vehicle Generator

2.4.1 FUEL TANK



Either the generator must share the vehicle engine's fuel tank, or a separate fuel tank must be installed 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. The manufacturer recommends that the fuel pickup tube be two to three 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.

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 J1737

(30R7), “Standard for Fuel and Oil Hose.” It must be approved for use with gasoline 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.

2.5 LP GAS FUEL SYSTEM

DANGER

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.

LP gas is highly EXPLOSIVE. The gas is heavier



than air and tends to settle in low areas. Even the slightest spark can ignite it and cause and explosion. Only competent, qualified people should be allowed to install, test, adjust or service an LP gas fuel system. Install the optional fuel system in compliance with applicable codes, standards and regulations. After the installation, do not do anything that might render the system in noncompliance with applicable codes and standards.

The LP powered range of generators are fitted with a nonadjustable, factory set system. These systems are tamper-proof to meet 1997 California Air Resources Board requirements for engine emission.

2.5.1 PARTS NOT INCLUDED IN FUEL



SYSTEM

The propane fuel system does NOT include such items as (a) gas tank, (b) gas piping, (c) fittings, (d) valves, and (e) primary regulator, used to store the gaseous fuel and deliver it to the gaseous fuel solenoid (Figure 2.15).

DANGER

Use only approved components in the fuel sup-



ply system. All components must be properly installed in accordance with applicable codes. Improper installation or use of unauthorized components may result in fire or an explosion. Follow approved methods to test the system for leaks. No leakage is permitted. Do not allow fuel vapors to enter the vehicle interior.

Section 2 – Installation

Recreational Vehicle Generator

Figure 2.15 – Typical Propane Gas Fuel System

2.5.2 SOME IMPORTANT CONSIDERATIONS



When installing an LP gas system, consider seriously the following items:

•

All fittings, lines, hoses and clamps must be

tight and free of leaks. Apply a pipe sealant to threads when assembling threaded connections. This reduces the possibility of leakage.

•

Test the entire fuel system for leaks using approved

test methods.

•

Optimum gas pressure at the inlet to the gaseous

fuel solenoid valve and secondary regulator is 11 inches water column.

•

The installer’s fuel supply connection point is at

the gaseous fuel solenoid valve. This is a 3/4-inch (female) connection. Provide a suitable 3/4-inch NPT (male) connector to attach to the fuel supply line.

•

Use a length of approved flexible fuel hose between

the gaseous fuel solenoid valve and rigid gas piping. The flexible line should be at least six (6) inches longer than necessary.

2.5.4 PRIMARY REGULATOR



Gas pressure delivered to the solenoid valve must be properly regulated by means of a primary gas regulator. Mount the primary regulator at the gas tank outlet or in the supply line from the gas tank. The following rules apply:

For best results, the primary regulator supplies

• gaseous fuel to the secondary regulator at 11 inches water column. Do NOT exceed 14 inches water column.

The installer must be sure the primary regulator is

• rated at sufficient gas flow to operate the generator plus all other gas appliances in the circuit.

NOTE:

Recommended MINIMUM gas flow rate for all aircooled generators is 67 cubic feet per hour.

If an existing primary gas regulator does not have a sufficient flow capacity for the generator and other gas appliances in the circuit, (a) install a primary regulator with adequate flow rate, or (b) install a separate regulator only and rated at least 67 cubic feet per hour. The inlet side of any primary regulator that supplies the generator must connect directly to a gas pressure tank. Do NOT tee the generator line into a gas circuit feeding other areas.

2.5.5 GASEOUS CARBURETION



LP gas vapors should be supplied to the secondary regulator inlet at about 11 inches water column (positive pressure). The engine pistons draw air in during the intake stroke (Figure 2.16). This air passes through a carburetor venturi, which creates a low pressure that is proportional to the quantity of air being pumped. The low pressure from the carburetor venturi acts on the regulator diaphragm to pull the diaphragm toward the source of low pressure. A lever attached to the diaphragm opens a valve to permit gas glow through the carburetor.

Figure 2.16 – LP Gas Carburetion Diagram

2.5.3 VAPOR WITHDRAWAL



LP gas is stored in pressure tanks as a liquid. The gas systems used with these generators were designed only for vapor withdrawal type systems. Vapor withdrawal systems use the gas vapors that form above the liquid fuel in the tank. Do NOT attempt to use the generator with any liquid withdrawal type system.

Section 2 – Installation

Recreational Vehicle Generator

The greater the airflow through the carburetor venturi, the lower the pressure at the venturi throat. The lower the pressure at the venturi throat, the greater the diaphragm movement, and the greater the movement of the regulator valve. The more the regulator valve opens, the greater the gas flow that is proportional to airflow through the generator.

The following facts about the secondary regulator must be emphasized:

•

The regulator must be sensitive to venturi throat

pressure changes throughout the operating range.

•

The regulator must be properly adjusted so it will

stop the flow of gas when the engine is not running (no air flow through the carburetor).

•

The slightest airflow (and vacuum in the venturi

throat) should move the regulator valve off its seat and permit gas to flow.

2.5.6 FUEL SUPPLY LINES



LP gas lines must be accessible, but protected

• against possible damage.

Do NOT connect electrical wiring to any LP gas fuel

• line or run wiring alongside the lines.

Route gas lines away from hot engine exhausts.

•

Retain gas lines with metal clamps that do not have

• sharp edges.

Install an approved length of flexible hose between

• the gaseous fuel solenoid valve and rigid fuel supply lines. The flexible line must be nonmetallic, nonorganic and nonconductive. It must be approved for use with LP gas.

2.5.7 EXCESS FLOW VALVE



LP gas tanks should have an excess flow valve, according to NFPA 501C, Paragraph 3-4.4. This valve and the gas lines must be carefully sized so the valve will close when a fuel line is severed or broken. Consult the Natural-LP Gas Association for information and limitations of excess flow valves.

Manual shutoff valves on the supply tank and elsewhere in the system must be fully open when operating the generator. The excess flow valve functions properly only if all valves are fully open.

The leak test must comply fully with NFPA, Paragraph

318. All connections, hoses, valve regulators, fittings, and other fuel system parts must be tested under gas or air pressure of not less than 90 psi (620 kPa), while using soap and water or an equivalent solution to check for leaks. Other approved methods of testing for leaks may be used, if appropriate. DO NOT USE ANY FLAME TO TEST FOR LEAKS.

DANGER

Gaseous fuel lines between the tank and the sec-



ondary regulator are under a positive pressure (about 11 inches water column). Gas pressure at the outlet side of the secondary regulator, however, is a negative pressure and can draw flame inside a line or fitting and cause an explosion.

2.6 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.

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.

2.5.8 LEAKAGE TESTS



Do not place the generator into service until the gas system has been properly tested for leaks. To test the system, a separate source of 12 volts DC is needed to open the gaseous fuel solenoid valve.

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.

2.6.1 MUFFLERS AND SPARK ARRESTORS



This muffler meets code and standard requirements of the U.S. Forest Service. Use only mufflers and parts approved by the manufacturer. 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, a spark arrestor must be installed. The vehicle owner or operator must maintain this device in good condition. In the state of California, the preceding is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands.

2.6.2 TYPE OF EXHAUST SYSTEM



Two types of exhaust systems for these generators are available from the manufacturer. They include the following:

“Out-the-bottom” exhaust system dimensions are

• 15/16” O.D., model 9742.

“Out-the-side” exhaust system dimensions are 1-

• 1/4” O.D., 18 gauge, model 4172.

NOTE:

No matter what type of exhaust kit best fits the recreational vehicle, the mounting base has openings for either “bottom-out” or “side-out” exhaust systems. Use the cover plate provided with the generator to cover the opening NOT used.

2.6.3 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 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.

Section 2 – Installation

Recreational Vehicle Generator

•

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 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.

2.7 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 appli-

• cable 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 com-

• partment (if used) must be vapor-sealed to prevent entry of flammable, explosive or poisonous gases into the vehicle.

2.7.1 ELECTRICAL JUNCTION BOX



Install an approved, square electrical junction box with a blank cover on the interior or exterior wall of the area planned 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.

Section 2 – Installation

Recreational Vehicle Generator

2.7.2 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 flexible metal conduit is used between the genera-

• tor 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) 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.

2.7.3 GENERATOR AC CONNECTIONS



Generator AC output leads T1 (red), T2 (white) and T3 (black) come out of the generator as shown in Figure 2.17. Leads T1 (red) and T3 (black) are “hot,” while T2 (white) is the grounded neutral lead. There is also a green lead that connects to ground in the junction box of the recreational vehicle.

Figure 2.17 – Generator AC Output Leads

T3 T2 T1

Green

(Ground)

Line T1 (red) to T2 (white) is protected against overload by a 30-amp circuit breaker (CB1). Use this line-to-neutral connection separately to operate 120-volt, single-phase, 60 Hertz, AC loads requiring up to 3,600 watts (3.6 kW) of power. Line T3 (black) to T2 (white) also is protected against overload by a 20-amp circuit breaker (CB2). Use this line-to-neutral connection separately to operate similar loads. However, be sure the total unit load does not exceed the maximum rating of the generator. The neutral line (T2, white) on all units is a grounded neutral.

Do NOT connect electrical loads in excess of any



circuit breaker rating or problems with circuit breaker tripping will develop, 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.

2.7.4 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 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 vaporproof along its entire length.

2.7.5 ISOLATING DIFFERENT POWER



SOURCES

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

2.18). An alternate method for isolating different power sources is by using an isolating receptacle (Figure 2.19). Whichever method is use, be certain that both power sources are NOT connected at the same time.

2.7.6 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.

2.8 BATTERY INSTALLATION

2.8.1 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, a battery with a larger capacity may be needed.

2.8.2 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.

These generators are rated at about 100 DC amperes of cranking current.

Select battery cables based on (a) cable length and (b) prevailing ambient temperatures. Generally, the longer the cable and the colder the weather, the 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

BATTERY

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.

2.9 OPTIONAL ACCESSORIES

A plug-in receptacle (Figure 2.21) is provided on the generator set, above the muffler enclosure. Use this receptacle to connect an optional remote-mounted start/stop panel to the generator. Installation of such a panel will permit starting and stoping the generator engine from any convenient location inside the vehicle.

Figure 2.21 – Remote Panel Plug-in Receptacle

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

2.8.3 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 2.20).

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 2.20).

3. Connect cables so the connectors are clean and

tight.

Section 3 – Post-installation Start-up Adjustments

2.9.1 REMOTE PANEL MODELS



The remote panels mount a rocker type start/stop switch, a “Generator Run” advisory lamp and an hourmeter. The hourmeter should be used in conjunction with the maintenance operations found in Part I of this manual.

Model 004057 includes the remote panel and a 10

• foot long, 4 wire harness.

Model 004184 includes the remote panel and a 30

• foot long, 4 wire harness.

3.1 POST INSTALLATION TESTS

The air-cooled generator set was factory tested and adjusted. It 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.

DANGER

Recreational Vehicle Generator

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 main circuit breakers to their “OFF” (or open) position.

2. Refer to Part I, section “Starting the Generator”, 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 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 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.

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. Be sure no gasoline fuel vapors enter the vehicle interior.

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. Do 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.

THE MANUFACTURER RECOMMENDS TESTING 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:

Section 7 – Warranty

Recreational Vehicle Generator

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

warranted 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 responsible

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:

1) Fuel Metering System:

1.1) Gasoline carburetor assembly and its internal components (if so equipped).
