OIL ALERT SYSTEM

The oil alert system protects the engine from low oil damage. This system automatically shuts down the engine and prevents engine restarting if the oil level falls too low.

Note:

When this happens, the engine switch remains in the ON position. The oil alert system is wired into the ON/OFF Switch.

If this system shuts down the engine, the engine will not start until you add oil. Add oil to engine (see Engine Oil, page 7).

Note:

Operate generator on a level surface. If not level, the oil may flow away from the oil level sensing device. This will cause the oil alert system to shut down engine.

See engine owner’s manual for more information.

Model MGH3000PR

FULL POWER SELECTOR SWITCH

All models except HWI3000, MGH3000, MGH3000PR, MGH7000D, MGH7000DI, and MGH10000A have a full power selector switch on the control panel. The switch has two positions: 120 VOLT ONLY, and 120/ 240 VOLT.

120 VOLT ONLY: This position sends full power to the 120V receptacles only. 240V power is not available. Use this position when powering 120V items only.

120/240 VOLT: This position sends full power to the 120/240V receptacle. It also powers the 120V receptacles at reduced wattage capacity.

IMPORTANT:

selector switch while powering electrical items. Unplug all items before moving switch. Failure to do so can damage switch. Models HWI3000, MGH3000, MGH3000PR, MGH7000D, MGH7000DI, and MGH10000A do not have this switch. These models provide full power to all receptacles.

(Models MGH5000DIE, MGH7000D, MGH7000DI, and MGH10000A)

Models MGH5000DIE, MGH7000D, MGH7000DI, and MGH10000A have electric starters. A battery is not supplied with generator. You must provide a 12-volt, 32amp-hour battery. For more battery information, see Battery, page 8.

GROUND FAULT CIRCUIT INTERRUPTER RECEPTACLE

All models (Except HWI3000) have a 120volt ground fault circuit interrupter (GFCI) receptacle. The GFCI receptacle is on the control panel or top cover of alternator (models MGH3000 and MGH3000PR only). The GFCI protects you against hazardous electrical shock caused when your body becomes a path through which electricity travels to reach ground. This could happen when you touch an appliance or cord that is ‘live’ through faulty mechanism, damp or worn insulation, etc.

When protected by the GFCI, you may still feel a shock, but the GFCI should cut it off quickly. A person in normal health should not receive serious injury. very small children may still be affected.

AUTO-IDLE SYSTEM

The Auto-Idle System allows the engine to idle down or run at a slower speed when the generator is not being used to supply power. The Auto-idle system can be turned ON or OFF by a rocker switch on the control panel. When the switch is in the OFF position, the engine runs at full speed all of the time. When the switch is in the ON position, the engine slows down to idle speed until an electrical load is applied. When a load is applied to the generator (an electrical item is plugged in and turned on) the engine speeds up to the preset speed required to produce the correct voltage.

IMPORTANT:

1 Amp is required to disengage the auto idle solenoid and cause the engine to come up to speed for correct voltage. Powering items at reduced engine speed will damage generator and powered items.

RECEPTACLE CIRCUIT BREAKER

The circuit breakers protect the receptacles and alternator. Overloading generator will trip circuit breaker. A short circuit in item being powered will also trip breaker. If this occurs, unplug electrical load from receptacle. Let circuit breaker cool down. Push circuit breaker button to reset.

Electric motors need higher starting current. They require up to three-times their rated wattage to start. The starting current needed may be too high. This can cause nuisance circuit breaker tripping. To help prevent this, start electric motors first. Connect additional items to generator after starting motors. If this continues to happen, reduce the total generator load.

STANDBY INSTALLATION TO HOME OR BUILDING

WARNING: Have standby installation performed by a skilled, licensed electrician. Do not let anyone else wire into a utility circuit. Personal injury, equipment damage, or damage to home could occur.

IMPORTANT:

This generator will not power your entire home. Most home utility electric service is more than 60 amps. This will exceed generator output. Only power needed items during a power outage. Make sure total wattage of electrical load does not exceed rated wattage of generator.

You may need to use this generator as a standby power source. During a power outage, the generator will power selected items in a building. Have generator and additional wiring installed by a skilled, licensed electrician. This is not a do-it-yourself job. Follow all local codes.

WARNING: The electrician must install a double-throw transfer switch. This isolates existing electrical circuits from the utility power line. If not isolated, generator output will back-feed into utility power line. This may electrocute a power company line repair person.

DETERMINING ELECTRICAL LOAD FOR GENERATOR

You must decide what electrical load your generator can power. Do this before using generator. Use the following four-step method. It will help you select a load that is not too large. Make sure total wattage of all electrical loads does not exceed rated wattage of generator. For rated wattage of your generator, see Specifications, page 5. Electric motors present a special problem when figuring load. Read Step 3 carefully.

1. Make two lists of items you want powered by generator. List all motors and motor powered appliances in one. List all lights, small appliances, etc. in the other. For standby service to home or building, only include items you must power.

2. Enter running watts of each item except motors. The light bulb or appliance nameplate lists its wattage. Remember, 1KW = 1000 watts.

Note:

The nameplate may not list wattage. It may only list volts and amps. The formula for finding wattage is: Volts x Amps = Watts. For example: An appliance nameplate states 3 amps at 120 volts. 3 amps x 120 volts = 360 watts.

3. Electric motors present a special problem. They require up to three-times their rated wattage to start. Chart 2, below, shows starting watts for differ-

ent size motors. For example: an electric motor nameplate states 5 amps at 120 volts. 5 amps x 120 volts = 600 watts running. Multiply this figure by

3. This will show the starting watts needed. 600 watts x 3 = 1800 watts to start. When figuring the generator load for motors, you must use the starting watts figure. Do not use the running watts figure.

Note:

Some motors require nearly the same wattage to run as to start. These items include saws, drills, hair dryers, and food mixers. See Chart 1 for typical appliance wattage examples.

4. Add watts and starting watts of all items. This total must not be larger than the rated wattage of your generator. It is a good idea to have up to 25% extra capacity for future needs or extra equipment.

OPERATION

GENERAL INFORMATION

This generator is not large enough to power your entire home. Do not connect generator to any existing electrical circuits. Plug items directly into generator receptacles. Do not exceed amperage rating of receptacles. Only use grounded cords.

DANGER: Never connect generator to any existing electrical circuits. The generator output will back-feed into the utility power line. This may electrocute a power company line repair person. Also, if generator is powering electrical circuits, the chance of an electrical fire exists.

Note:

We supply the engine owner’s manual with generator. Refer to that manual for questions concerning engine operation.

Model MGH10000A also has a 120/240V, 50-amp receptacle (see Figure 17).

Model HWI3000 has only the 120V, 20amp duplex receptacle.

Models MGH3000 and MGH3000PR have only the 120V, 15-amp GFCI duplex receptacle.

PRESTART

Operate generator on a firm, dry, and clean surface. The surface must be level. Protect generator from heavy dust, sand, dirt, rain, or snow. Do not locate generator near standing water and snow. Make sure area is wellvented.

WARNING: Only responsible

adults should use generator. Never let anyone operate generator without proper instructions.

Note:

If oil level is too low, oil alert system will keep engine from starting (see Oil Alert System, page 6). Make sure oil level is full before starting. See Engine Oil, page 7.

Before starting the engine, disconnect all electric loads from generator.

STARTING

IMPORTANT:

The throttle is locked in preset position. Do not adjust throttle. Preset position lets engine run at 3600 RPM under load. The engine must maintain 3600 RPM for generator to create correct voltage. Running engine at lower speeds will damage generator and powered items.

IMPORTANT:

electrical loads connected. Start engine before adding electrical loads.

1. Make sure gasoline tank is full. See

Fuel, page 7 for fuel information.

2. Move fuel valve lever to the ON posi-

tion except on Model MGH3000PR (see Figure 19).

3. Move choke lever fully to the left for

all models except MGH3000PR or MGH10000A (see Figure 19). Pull choke rod out for Model MGH3000PR (see Figure 20) or choke button out for Model MGH10000A (see Figure 21). This closes the choke.

OWNER’S MANUAL

Note:

The 250 Volt/50 Amp receptacle is not connected through the Auto-Idle circuit. The Auto-Idle switch must be turned off to get full power out of this receptacle (see Figure 26).

6. The Auto-Idle system should be turned OFF when generator is shut down.

Adjusting the Idle Speed

IMPORTANT:

• If the idle speed becomes too high.

• If the engine idle speed will not regulate (en-

gine idles and speeds up again and again).

1. Turn Auto-Idle switch OFF. Start engine. Allow engine to warm up with no load for five minutes.

WARNING: Always set the idle speed before turning on the AutoIdle. If idle speed is not set, the larger resistor on the control board may become hot. Heat from the resistor may damage the protective coating on the control board.

Adjust the idle speed only:

8. Turn Auto-Idle switch ON. Make sure solenoid is engaged. When engaged, the punger is pulled back into the solenoid.

9. If the engine speed is too slow , the engine will want to "hunt" or speed up and slow down repeatedly. When this occurs, increase engine speed by adjusting throttle stop screw on carburetor (refer to Carburetor Adjustment in Honda Engine Manual).

10. Replace the engine linkage cover (Models MGH4000CI, MGH5000DI, MGH5000DIE, MGH6000DI, and MGH7000DI).

2. Remove engine linkage cover (Models MGH4000CI, MGH5000DI, MGH5000DIE, MGH6000DI, and MGH7000DI).

3. Push plunger into solenoid body to manually engage solenoid and set idle speed.

4. Loosen the M8 nut that holds the solenoid mounting bracket to the generator (Models MGH4000CI, MGH5000DI, MGH5000DIE, MGH6000DI, and MGH7000DI. See Figure 27). Do not loosen bolt that holds the solenoid mounting bracket to the generator on Model MGH10000A (see Figure 28).

5. Slowly pull solenoid bracket away from engine (on Model MGH10000A this will require bending the bracket slightly).

6. With a volt meter, check the no-load output voltage at the 120-volt duplex receptacle. At proper idle speed (2680 minimum RPM) the meter should read 50-60 volts. Lower settings will cause the Auto-Idle to not operate properly.

7. After reaching proper idle speed, tighten M8 nut to secure solenoid mounting bracket (Models MGH4000CI, MGH5000DI, MGH5000DIE, MGH6000DI, and MGH7000DI (see Figure 27).

HIGH ALTITUDE OPERATION

This generator will not perform well at high altitudes without proper adjustment. See engine owner’s manual for details.

ADDING ELECTRICAL LOADS

IMPORTANT:

Make sure total wattage of all electrical loads does not exceed rated wattage of generator. Overloading may shorten generator life. It could also cause internal damage to generator. Overloading will trip circuit breaker.

IMPORTANT:

MGH3000, MGH3000PR, MGH7000D, MGH7000DI, and MGH10000A) Keep full power selector switch in the 120 VOLT ONLY position if only powering 120V items. Only move switch to 120/240 VOLT position if powering 240V items.

1. Check items to be powered. Their nameplate lists their wattage ratings.

Note:

trical motors are misleading. They may require up to three-times their rated wattage to start. You must figure total electrical load wattage. Make sure total wattage of all electrical loads does not exceed rated wattage of generator. See Determining Electrical Load For Generator, page 10.

2. Start engine. Let engine reach full speed.

3. Connect electrical loads one at a time. If the load consists of electric motors, start them first. Always start the largest first. Start each motor individually .

Do not overload generator.

WARRANTY INFORMATION

KEEP THIS WARRANTY

Model Serial No. Date Purchased

Always specify model and serial numbers when communicating with the factory. We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard

written warranty. We make no other warranty, expressed or implied.

Note:

The two-year limited warranty below covers all non-engine parts of this generator including the alternator. Honda

warrants the engine. See engine owner’s manual for engine warranty information.

TWO-YEAR LIMITED WARRANTY

GASOLINE PORTABLE GENERATORS

DESA International warrants each alternator, generator, or electric product of its manufacture, to be free from defects in material and workmanship for two years from the date of ﬁrst purchase from an authorized dealer, provided that the product has been properly installed, maintained, and operated in accordance with all applicable instructions. The bill of sale or proof of purchase must be presented at the time a claim is made under this warranty.

This warranty is extended only to the original retail purchaser. This warranty covers only the parts and labor required to restore this unit to its proper operating condition. Warranty parts must be obtained through factory authorized dealers and service centers for this product. These dealers and service centers will provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become damaged as a result of misuse, abuse, negligence, accident, lack of proper maintenance, alteration, modification, tampering, contaminated fuels, repair using improper parts, or repair by anyone other than an authorized dealer or service center. Routine maintenance is the responsibility of the owner. Travel, handling, transportation, and incidental costs associated with warranty repairs are not reimbursable under this warranty and are the responsibility of the owner.

DESA International makes no warranty with respect to the engine and engine components not of its manufacture. They are subject to warranties of their manufacturers.

To the full extent allowed by the law of the jurisdiction that governs the sale of the product, this express warranty excludes any and all other expressed warranties and limits the duration of any and all implied warranties, including warranties of merchantability and fitness for a particular purpose to two years from the date of first purchase, and DESA International’s liability is hereby limited to the purchase price of the product and DESA International shall not be liable for any other damages whatsoever including indirect, incidental, or consequential damages.

Some states do not allow limitation of how long an implied warranty lasts or an exclusion or limitation of incidental or consequential damages, so the above limitation of damages may not apply to you.

This warranty provides the original purchaser with specific rights. For information regarding those rights, please consult the applicable state laws.
