Electrocution hazard. Never use the generator in a location that is wet or damp. Never expose the generator to rain, snow, water spray, or standing water while in use. Protect the generator from all hazardous weather conditions. Moisture or ice can cause a short circuit or other malfunction in the electrical circuit.

GENERAL SAFETY PRECAUTIONS

  • Never use the generator to power medical support equipment.
  • DO NOT operate the generator when you are tired or under the influence of drugs, alcohol, or medication.
  • When this generator is used to supply a building wiring system the generator must be installed by a qualified electrician and connected to a transfer switch as a separately derived system in accordance with NFPA 70, National Electrical Code.
  • Only use OUTSIDE and far away from windows, doors, and vents as recommended by the US Department of Health and Human Services Centers for Disease Control and Prevention. Your specific home and/or wind conditions may require additional distance.
  • If you begin to feel sick, dizzy, or weak while using the generator, move to fresh air IMMEDIATELY. See a doctor, as you can have carbon monoxide poisoning.
  • While operating and storing, keep at least five feet of clearance on all sides of the generator, including overhead. Allow the generator to cool a minimum of 30 minutes before storage. The heat created by the muffler and exhaust gases could be hot enough to cause serious burns and/or ignite combustible objects.
  • DO NOT use a generator with electrical cords which are worn, frayed, bare, or otherwise damaged.
  • All electrical tools and appliances operated from this generator must be properly grounded by use of a third wire or be double-insulated.
  • DO NOT touch the muffler or engine. They are very HOT and will cause severe burns. Do not put body parts or any flammable or combustible materials in the direct path of the exhaust.
  • ALWAYS remove any tools or other service equipment used during maintenance from the generator before operating.
  • Avoid skin contact with engine oil or gasoline. Wear protective clothing and equipment. Wash all exposed skin with soap and water.

FUEL SAFETY

  • Store fuel in a container approved for gasoline.
  • Do not smoke when filling the generator with gasoline.
  • Wear eye protection while refueling.
  • Never remove the fuel cap when the generator is running. Shut off the engine and allow the unit to cool at least five minutes. Remove the fuel cap slowly to release pressure, keep fuel from escaping around the cap, and to avoid the heat from the muffler igniting fuel vapors. Tighten the fuel cap securely after refueling.
  • Never overfill the fuel tank. Leave room for fuel to expand. Overfilling the fuel tank can result in a sudden overflow of gasoline and result in spilled gasoline coming in contact with HOT surfaces.
  • Spilled fuel can ignite. If fuel is spilled on the generator, wipe up any spills immediately. Dispose of rag properly. Allow the area of spilled fuel to dry before operating the generator.
  • Store any containers containing gasoline in a well-ventilated area, away from any combustibles or source of ignition.

GASOLINE AND GASOLINE VAPOR
warning 2DANGER
Fire and explosion hazards. Gasoline is highly explosive and flammable and can cause severe burns or death.

  • Gasoline is highly flammable and explosive.
  • Gasoline can cause a fire or explosion if ignited.
  • Gasoline is a skin irritant and needs to be cleaned up immediately if it comes in contact with the skin.
  • Gasoline has a distinctive odor, this will help detect potential leaks quickly.
  • In any petroleum gas fire, flames should not be extinguished unless by doing so the fuel supply valve can be turned OFF. This is because if a fire is extinguished and a supply of fuel is not turned OFF, then an explosion hazard could be created.
  • Gasoline expands or contracts with ambient temperatures. Never fill the gasoline tank to full capacity, as gasoline needs room to expand if temperatures rise.

LIQUID PETROLEUM GAS (LPG/PROPANE)
warning 2 WARNING
Fire and explosion hazards. Never use a gas container, LPG/propane connector hose, LPG/propane tank or any other fuel item that appears to be damaged.
warning 2 CAUTION
Fire and explosion hazards. Only use approved LPG/ propane tanks with an Overfilling Prevention Device (OPD) valve. Always keep the tank in a vertical position with the valve on top and placed at ground level on a flat surface. Do not allow tanks to be near any heat source. When transporting and storing, turn the propane tank valve to the fully closed position and disconnect the tank. Make sure to always cover the generator inlet and tank outlet with protective plastic caps.

  • LPG/Propane is highly flammable and explosive.
  • Flammable gas under pressure can cause a fire or explosion if ignited.
  • LPG/Propane can settle in low places because it is heavier than air.
  • LPG/Propane has a distinctive odor added to help detect potential leaks.
  • Always keep an LPG/Propane tank in an upright position.
  • When exchanging LPG/propane tanks, be sure the tank valve is the same type.
  • In case of an LPG/propane fire, do not attempt to extinguish it unless the fuel supply can be shut off safely.
  • LPG/propane will burn the skin. Prevent skin contact at all times.
  • Keep the propane tank away from the generator exhaust.
  • A step-down regulator is required when using LPG/ propane tanks over 100 gallons. The pressure as measured at the regulator mounted to the generator must be 7” to 14” of the water column.
  • Large (500–1000 gallon) LPG/propane tanks will require a certified plumber to install the fuel line to the generator and the loose regulator is not used (the regulator that is attached to the fuel tank). The pressure as measured at the regulator mounted to the generator must be 7” to 14” of the water column. A certified plumber must ensure that the pressure is correct or install a step-down regulator if needed.

warning 2 WARNING
Fire and explosion hazard. If there is a strong smell of propane while operating the generator, fully close the LPG/propane tank valve immediately. Once the propane is off, use soapy water to check for leaks on the hose and connections on the tank valve and the generator. Do not smoke or light a cigarette or check for leaks using any open flame source such as a match or lighter. If a leak is found, contact a qualified technician to inspect and repair the LPG/propane system before using the generator.

When starting the generator:

  •  Make sure that the fuel cap, air filter, spark plug, fuel lines, and exhaust system are properly in place.
  • If you spill any gasoline on the tank, allow it to fully evaporate before operating.
  • Make sure the generator and LPG/propane tank are on a flat surface before operating.
  • If there is a propane odor do not start the unit because there may be a potential leak. Never place an LPG/ propane tank near the engine exhaust.

When transporting or servicing the generator:

  • Make sure the LPG/propane tank and LPG/propane hose are not attached to the generator.
  • Disconnect the spark boot to prevent accidental starting.

When storing the generator:

  • Store away from sparks, open flames, pilot lights, heat, and other sources of ignition.
  • Do not store gas or an LPG/propane tank near furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions.

SAFETY LABELS AND DECALS

Westinghouse WGen12000DFc Dual Fuel Portable Generator - fig 4

CO SENSOR
The carbon monoxide (CO) sensor monitors for the accumulation of poisonous carbon monoxide gas around the generator when the engine is running. If unsafe levels of CO gas are detected, the CO Sensor automatically shuts down the engine. The CO Sensor will also detect the accumulation of carbon monoxide from other fuel-burning sources used in the area of operation. For example, if the exhaust of fuel-burning tools is pointed at a CO Sensor-equipped generator, a shut-off may be initiated due to unsafe CO levels. This is not an error. Hazardous carbon monoxide has been detected. Move and redirect any additional fuel-burning sources to dissipate carbon monoxide away from personnel and occupied buildings.

Note: Remote start-equipped generators must be restarted with the START/STOP button on the control panel after an automatic shutdown occurs.

Generators are intended to be used outdoors, far from occupied buildings and the exhaust is pointed away from personnel and buildings. If misused and operated in a location that results in the accumulation of CO, like in a partially enclosed area, the CO Sensor shuts off the engine. A RED indicator light will indicate the unit was shut down due to an unsafe level of CO being detected around the generator. Before approaching the generator allow the CO to dissipate from around the generator. The CO Sensor DOES NOT replace carbon monoxide alarms. Install battery-powered carbon monoxide alarm(s) in your home.

warning 2WARNING
Automatic shutoff accompanied by a flashing RED light in the CO Sensor portion of the control panel is an indication that the generator was improperly located. If you start to feel sick, dizzy, weak, or carbon monoxide detectors in your home indicate an alarm, get to fresh air immediately. Call emergency services. You may have carbon monoxide poisoning.

CONTROL PANEL CO AUTO-SHUTOFF

CO SENSOR INDICATOR LIGHTS

ColorDescription
REDUnsafe levels of carbon monoxide accumulated around the generator. After shut-off, the RED indicator light in the CO Sensor area of the control panel will flash to provide a notification that the generator was shut off due to an accumulation of unsafe CO levels. The RED light will flash for at least five minutes after a CO shut-off.
Move the generator to an open, outdoor area far away from occupied spaces with exhaust pointed away. Once relocated to a safe area and the red light is off, the generator can be restarted. Introduce fresh air and ventilate the area where the generator had shut down.
YELLOWA CO sensor system fault occurred. When a system fault occurs, the generator is automatically shut down and the YELLOW indicator light in the CO auto-shutoff area of the control panel will flash to provide a notification that a fault has occurred. The YELLOW light will flash for at least five minutes after a fault. The generator can be restarted but may continue to shut off. A CO sensor fault can only be diagnosed and repaired by an authorized Westinghouse service center.

FREQUENCY OF USE
If the generator will be used on an infrequent or intermittent basis (more than one month before the next use), refer to the Battery Maintenance and Storage sections of this manual for information regarding battery charging and fuel deterioration.

AC CIRCUIT BREAKERS
The circuit breakers will automatically switch OFF if there is a short circuit or a significant overload of the generator at each receptacle.
If an AC circuit breaker switches OFF automatically, check that the appliance is working correctly and it does not exceed the rated load capacity of the circuit before resetting the AC circuit breaker ON.
The main circuit breaker controls the total output of all outlets to protect the generator from overload or short circuits.

Westinghouse WGen12000DFc Dual Fuel Portable Generator - fig 27

GENERATOR CAPACITY
NOTICE
Do not overload the generator’s capacity. Exceeding the generator’s wattage/amperage capacity can damage the generator and/or electrical devices connected to it.

Make sure the generator can supply enough continuous (running) and surge (starting) watts for the items you will power at the same time.
The total power requirements (Volts x Amps = Watts) of all appliances connected must be considered. Appliance and power tool manufacturers usually list rating information near the model or serial number.
To determine power requirements:

  1. Select the items you will power at the same time.
  2. Total the continuous (running) watts of these items. This is the amount of power the generator must produce to keep the items running. See the wattage reference chart on the next page.
  3. Estimate how many surge (starting) watts you will need. Surge wattage is the short burst of power needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator. Because not all motors start at the same time, total surge watts can be estimated by adding only the item(s) with the highest additional surge watts to the total rated watts from step 2.

POWER MANAGEMENT
To prolong the life of the generator and attached devices, use care when adding electrical loads to the generator. There should be nothing connected to the generator outlets before starting the engine. The correct and safe way to manage generator power is to sequentially add loads as follows:

  1. With nothing connected to the generator, start the engine as described in this manual.
  2. Plug in and turn on the first load, preferably the largest load you have.
  3. Permit the generator output to stabilize (the engine runs smoothly and the attached device operates properly).
  4. Plug in and turn on the next load.
  5. Again, permit the generator to stabilize.
  6. Repeat steps 4 and 5 for each additional load.

STORAGE
Proper storage preparation is required for trouble-free operation and generator longevity.

NOTICE
Gasoline stored for as little as 30 days can deteriorate, causing gum, varnish, and corrosive buildup in fuel lines, fuel passages, and the engine. This corrosive buildup restricts the flow of fuel, which can prevent the engine from starting after a prolonged storage period. The use of fuel stabilizers significantly increases the storage life of gasoline. Full-time use of fuel stabilizer is recommended. Follow the manufacturer’s instructions for use.

STORAGE TIME RECOMMENDED PROCEDURE
Less than 1 monthNo service is required.
2 to 6 monthsFill with fresh gasoline and add a gasoline stabilizer. Drain the carburetor float bowl.
6 months or longerDrain the fuel tank and carburetor float bowl.

SHORT TERM STORAGE

  • Allow the generator to cool a minimum of 30 minutes before storage.

PROBLEMPOSSIBLE CAUSECORRECTION
Frost on the propane tank or regulator‘If the temperature of the propane tank drops below the dew point, condensation on the tank may turn to frost or ice. This typically occurs in humid conditions.Providing all the propane fuel handling equipment is functioning normally, no correction is needed.
The Propane tank is not equipped with an Overfilling Prevention Device (OPD).If you suspect your propane fuel tank is not equipped with an OPD device, discontinue operation immediately and replace the propane fuel tank with a propane tank equipped with an OPD.
The propane fuel tank was overfilled.If you suspect your propane fuel tank has been overfilled, discontinue operation immediately and return the propane fuel tank to the place of purchase or refilling.
Propane fuel smellFuel regulator or fuel hose and fittings not securely sealed.Using a soap solution check each connection and tighten as needed.
Propane fuel regulator vent active.The propane fuel regulator is equipped with a vent that will allow a small amount of propane fuel vapor to escape from the regulator when the propane tank valve is opened. This can be normally provided the venting of the propane is brief. If you suspect that this is abnormal, immediately discontinue use and have the propane regulator inspected by a qualified technician.
Residual fuel from the carburetor disperses after the operation.Normal, no correction is needed.
Poor performance or engine stalling on PropanePropane fuel line kinked or crushed.Inspect the propane fuel line and remove kinks or other obstructions.
Fuel selector valve is not properly positioned.Rotate the fuel valve fully until the pointer is directly in line with the desired fuel.
Gasoline is not purged from the carburetor before switching to propane.Close the propane fuel tank valve. Move the fuel selector switch to gas. Start the engine and allow the engine to run until the gasoline has been consumed in the carburetor. Begin the propane start-up procedure.
