Owner’s Manual

Instructions for Installation/Set-up, Operation, Servicing, & Storage

Portable, Outdoor Use-Only, Gasoline Generator

Can be used to power individual appliances plugged directly into the generator’s outlets, or as a back-up connection to a building’s power supply (via a professionally installed UL-listed transfer switch).

WARNING

READ and UNDERSTAND this manual completely before using the generator! Failure to properly set up,

operate, and maintain this generator could result in serious injury or death from carbon monoxide poisoning, electric shock, fire/explosion, or burns. Generator has been shipped WITHOUT engine oil, Check the oil level

using the dipstick and add oil as needed. In particular, be aware of the following hazards:

CO Poisoning

Generators give off carbon monoxide, a poisonous gas that can kill you. You CANNOT smell it, see it, or taste it.

• ONLY run generator OUTDOORS and AWAY from building air intakes. NEVER run generator inside any enclosed or

semi-enclosed spaces, including homes, basements, garages, sheds, boxes, RVs, boats or pick-up truck beds. These spaces can trap poisonous gases, EVEN if you run a fan or open windows.

• Install carbon monoxide alarms inside nearby structures/buildings (battery-operated, or plug-in with battery backup).

Electric shock / Electrocution

• High voltage electricity from generator can kill. DO NOT operate in wet locations. Be sure generator is properly

grounded. Use only UL-listed, outdoor-rated grounded extension cords of proper size.

• NEVER plug the generator directly into a wall outlet. ANY connection to a building’s electrical system MUST

ISOLATE THE GENERATOR FROM UTILITY POWER via a UL-listed transfer switch installed by a licensed electrician. Otherwise, back feed from the generator into the power grid could kill utility workers.

Fire / Explosion

• DO NOT overload generator (per rated capacity), and OPERATE ONLY in an area with adequate cooling ventilation so

engine does not overheat. Exhaust can be extremely hot. Keep muffler at least 7 feet from all combustible objects.

• All fuels are flammable. Never fuel a running or hot engine. Never pump fuel directly into generator at gas station – use

approved container to transfer fuel. Ensure there are no fuel leaks, and keep sources of sparks and flames away.

• ALWAYS keep a fire extinguisher rated “ABC” nearby.

STOP!

CHOOSE THE RIGHT GENERATOR FOR YOUR NEEDS. See the “Power Load Planning & Management” section

of this manual to determine your power load requirements and then compare to the generator’s rated capacity.

INSPECT COMPONENTS: Closely inspect to make sure no components are missing or damaged. See the “Unpacking

& Delivery Inspection” section for instructions on whom to contact to report missing or damaged parts.

ARRANGE FOR PROFESSIONAL INSTALLATION of a transfer switch if you will be connecting the generator to

your building’s electrical system. See the “Installation/Initial Set-Up” section for more information about this requirement.

Low Oil Warning Light

When the oil level falls below the lower level, the oil warning light 1 comes on and the engine stops automatically. The engine will not start again until oil has been added.

Note: If the engine stalls or does not start, turn the engine switch to “ON”

and then pull the recoil starter. If the oil warning light flickers for a few seconds, the engine oil is insufficient. Add oil and restart.

Overload Indicator Light (Red)

The overload indicator light 1 comes on when an overload of a connected electrical device is detected, the inverter control unit overheats, or the AC output voltage rises. The AC protector will trip, stopping power generation in order to protect the generator and any connected electric devices. The output indicator light (green) will go off and the overload indicator light (red) will stay on but the engine does not stop running. When the overload indicator light comes on and power generation stops, proceed as follows:

1) Turn off any connected electric devices and stop the engine.

2) Reduce the total wattage of connected electric devices within the

rated output.

3) Check for blockages in the cooling air inlet and around the control

unit. If any blockages are found remove.

4) After checking, restart the engine.

Note: The overload indicator light may come on for a few seconds at first when using electric devices that require a large starting current, such as a compressor or a submersible pump. However, this is not a malfunction.

Output Indicator Light (Green)

The Output Indicator Light 1 comes on when the engine starts and produces power.

Power Load Planning & Management

WARNING

NEVER exceed the rated wattage capacity of your generator. OVERLOADING may cause SERIOUS DAMAGE to the generator and

attached electrical devices, and may result in fire.

Your generator MUST BE SIZED PROPERLY to provide both the running and starting (surge) wattage of the devices you will be powering. Before using your generator, determine the running and starting wattage requirements of all the electrical devices you will be powering simultaneously. The sum of the running and starting wattages of the devices being powered must not exceed the continuous output rating of your generator. (The continuous output rating of your generator is listed in the “Specifications” section of this manual.) Note that:

• Devices without electric motors such as light bulbs, radios, and televisions have the same

running and starting wattage.

• Devices with electric motors such as refrigerators, compressors, and hand tools typically

require a starting wattage that is 3 to 5 times greater than the running wattage.

The running and starting wattage requirements are often listed on a device’s nameplate. If wattage

is not given on the device’s nameplate, the wattage may be calculated by multiplying the nameplate

voltage by nameplate amperage, Watts = Volts X Amps.

Example conversion to watts:

120 Volts X 5 Amps = 600 Watts

If only the running voltage is given on the nameplate for a device with an electric motor, the starting wattage can be approximated to be three to five times the running wattage.

Estimates for the running wattage requirements for common devices are listed in Table 1 below. Guidance for starting wattages is provided in the table’s footnotes.

Power Load Planning & Management

(b) For extremely hard to start loads such as air conditioners and air compressors, consult the equipment dealer to

determine maximum wattage

To calculate the running and starting wattage requirements for the devices you will be powering, follow these steps:

1. Make a list of all electrical devices you will be powering at the same time with the generator.

2. List the greater of the running or starting wattage next to each device as obtained from the

devices’ nameplate or Table 1. If only the running wattage for a device with an electric motor is known, the starting wattage can be estimated to be at least 3 times the running wattage.

3. Add the wattages for all devices on your list. This total must be lower than the continuous

output rating of your generator.

Example:

Air Conditioner, Window (10,000 BTU)

2200 W

Sump pump (1/3 hp)

1300 W

Total

6750W

In this example, the generator must have a continuous output of at least 6750 watts in order to power all of the devices simultaneously.

The overload indicator light 1 comes on when the total wattage exceeds the generators capability. If that happens, proceed as follows:

1. Turn off any connected electric devices and stop the generator.

2. Reduce the total wattage of connected electric devices within the rated output.

3. Check for blockages in the cool air intake (louver) and around the control unit. If any

blockages are found remove.

4. After checking, restart the generator.

You can increase the number of devices your generator can power by staggering the load on the generator. For example, you could alternately power your refrigerator and air conditioner for limited periods of time -- powering only one of the devices at a time and never powering both at the same time.

STAGGERING LOADS

Installation / Initial Set-Up

There are a number of important steps required to set up your generator for initial use. These steps are:

Steps for Installation / Initial Set-Up

1. Unpacking & delivery inspection.

2. Planning the power load to stay within the generator’s rated

capacity.

3. Setting up generator for the type of power generation you need: a. portable power source, or

b. connected to a building as a back-up power source.

4. Selecting a site for using the generator.

5. Grounding.

Each of these steps is discussed in detail below:

1. Unpacking & Delivery Inspection

You should inspect the generator immediately after you receive delivery.

See the “Machine Component Identification” section of this manual for a

diagram of the generator and its components.

• If you are missing or have damaged components, contact Product Support at 1-866-443-2576.

2. Planning the Power Load

Plan your power load so that you do not exceed the generator’s rated capacity.

See the “Power Load Planning & Management” section of this manual to review how to plan and

manage power loads for the generator.

Installation / Initial Set-Up

3. Set-up either as a BUILDING BACK-UP or PORTABLE Power Source

This generator is designed to provide up to its rated amount of electrical power. It can supply electricity in two ways:

1. As a back-up, standby power source for a building. For this application, you must arrange for a

licensed electrician to connect the generator to your building’s electrical system via the installation

of an UL-approved transfer switch. The transfer switch must be installed in accordance with building electrical code and guidelines supplied by your power company.

2. As a portable power source. You can plug appliances or tools directly into the generator’s

electrical outlets.

Specific requirements for each are given below.

Note: Regardless of whether you use your generator as a back-up power source connected to a

building or as a portable power source, you must not overload the generator. Overloading may cause serious damage to the generator and attached electrical devices.

Using as a Back-up Power Source for a Building

Contact a licensed electrician to install an UL-listed transfer switch if you

want to use your generator as a back-up power source for a building. What does a transfer switch do? It:

a) Safely connects the generator to your building’s electrical system by

isolating your generator from your utility company’s power lines, AND

b) Connects your generator to a critical subset of your building’s circuits that

are needed for emergency power needs.

If your generator will be connected to your building’s electrical system, it MUST

ALWAYS be isolated from the utility power grid with a UL-listed transfer switch installed by a licensed electrician in compliance with all applicable building and

electrical codes, and in accordance with guidelines supplied by your power company.

DANGER:

A transfer switch must be installed in order to isolate your generator from the utility power grid. If your generator is NOT properly isolated from the utility system, serious hazards will arise:  When your generator is running, its output will back feed into the

utility power line and transformer that are normally used to provide you with power. The transformer will step up the current to the

Installation / Initial Set-Up

normal line voltage. An unsuspecting utility line worker working on what he thinks is a deactivated line could be electrocuted.

 If your generator is connected (running or not) when utility power is

restored, your generator will be destroyed. It could also explode or cause fire.

In addition to isolating your generator from the utility system, the transfer switch connects your generator to a limited set of circuits in your building that have been chosen as critical to operate during a power outage.

The generator may not power your entire home -- you must work with the installing electrician to determine which devices/appliances you wish to power during an outage. The electrician can help you determine which circuits and devices can be powered simultaneously without overloading the generator.

(See the previous section of this manual entitled “Power Load Planning &

Management” for more information on load application and selection.)

Using as a Portable Power Source

When using the generator as a portable power source, you can plug electric

devices and appliances directly into the generator’s electrical outlets. There are different kinds of electrical outlets on your generator:

1. 120 Volt, 20 Amp duplex straight-blade receptacles (NEMA 5-20R

duplex receptacle compatible with NEMA 5-20P or 5-15P mating plugs).

2. 120 Volt, 30 Amp locking receptacle (NEMA L5-30R receptacle

compatible with NEMA L5-30P mating plug).

3. Make sure you plug each electrical device/appliance into the correct

generator outlet based on the device’s plug configuration and voltage/amperage rating. Never exceed the amperage rating of an outlet.

4. Extension cords may be used to power devices that are located at a

distance from the generator. However, use only UL-listed, outdoor-rated, grounded extension cords of the proper size. Use Table 2 below to choose an adequately sized extension cord according to the amperage of the device being used and the length of the cord.

Installation / Initial Set-Up

4. Select a Suitable Site

Before using the generator, you must select a suitable OUTDOOR location for installation and operation. This location should meet all of the criteria listed below.

WARNING:

You must choose a suitable site for operating your generator to avoid equipment damage and/or injury and possible death from carbon monoxide poisoning, electric shock, or fire. Choose a site that meets all of the criteria specified.

Dry, level surface

The generator should be positioned on a dry, firm, level surface.

Ensure that the generator sits level and will not slide or shift during operation. If applicable, block the generator’s wheels to prevent sliding and shifting.

Outdoors only – dangerous carbon monoxide exhaust

WARNING: Carbon monoxide poisoning hazard

The exhaust from your generator contains carbon monoxide (CO), a poisonous gas that can kill. You cannot smell it, see it, or taste it.

Carbon monoxide exhaust is given off whether you are using gasoline, natural gas, or propane as the fuel source to power the generator.

Follow the directions below for choosing a location to operate your generator in order to avoid carbon monoxide poisoning.

The location you choose to operate the generator must be OUTDOORS and away from all air intakes:

• Never run the generator inside any closed or semi-enclosed spaces (even if

outdoors), including homes, garages, basements, sheds, or boxes. These spaces can trap poisonous gases, even if you run a fan or open windows.

• Never place the generator immediately adjacent to a building or other

structure – allow at least 7 feet clearance.

• Place the generator so that the exhaust fumes will not be directed towards

people or building air intakes.

• Ensure that working, battery-operated or battery back-up carbon monoxide

alarms are used in any dwelling/structure that is in close proximity to the running generator.

• Note that this generator is NOT designed or approved for use in vehicles

or marine applications. Never run the generator inside RVs or other vehicles, on boats, or on pick-up truck beds.

WARNING:

Never attempt to attach ductwork to the muffler system to allow for installation inside an enclosure. This could cause hot air deflection, heat build-up, and increased exhaust back-pressure, resulting in possible exhaust leakage or damage to the generator.
