1. Introduction
This manual provides essential information for the safe and efficient operation of your Westinghouse iGen5000DFcv Dual Fuel Inverter Generator. Designed for versatility and quiet performance, this generator offers 5000 peak watts and 3900 rated watts, operating on either gasoline or propane. Its compact design, combined with a wheel and handle kit, ensures portability for various applications, from recreational activities to emergency backup power.
2. Safety Information
Always read and understand all safety warnings and instructions before operating the generator. Failure to do so can result in serious injury or death.
- Carbon Monoxide Hazard: Generators produce carbon monoxide (CO), an odorless, colorless, poisonous gas. Operate the generator outdoors in a well-ventilated area, far from windows, doors, and vents. The iGen5000DFcv is equipped with an automatic Carbon Monoxide (CO) shutdown sensor for added safety.
- Fire Hazard: Gasoline and propane are highly flammable. Store fuel in approved containers and away from ignition sources. Do not refuel while the engine is running or hot.
- Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are secure and properly grounded.
- Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for a period after shutdown. Avoid contact with hot surfaces.
- California Proposition 65 Warning: This product can expose you to chemicals including engine exhaust, carbon monoxide, and lead, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

- Dual USB Ports: For charging sensitive electronics.
- Eco Mode Switch: Engages variable engine speed for maximum fuel efficiency and quieter operation.
- Propane Connection: Inlet for connecting a propane tank.
- Fuel Selector: Switch between gasoline and propane operation.
- LED Data Center: Digital display showing fuel level, power output, remaining run time, voltage output, and lifetime hours.
- Carbon Monoxide Auto-Shutdown Indicator: Alerts and shuts down the generator if CO levels become unsafe.
- Parallel Ports: Allows connection of two compatible Westinghouse inverter generators for increased power output.
5. Setup
5.1 Initial Preparation
- Add Engine Oil: Place the generator on a level surface. Remove the oil fill cap/dipstick. Using the provided funnel, carefully pour the entire bottle of 4-stroke engine oil into the engine crankcase. Do not overfill.
- Add Fuel:
- Gasoline: Ensure the generator is off and cool. Open the fuel cap and fill with fresh, unleaded gasoline (minimum 87 octane) up to the fill neck. Do not overfill.
- Propane: Connect the provided propane hose to the generator's propane inlet and to a standard propane tank. Ensure connections are tight.
- Wheel and Handle Kit Assembly: Attach the wheels and extendable handle according to the separate assembly instructions provided in the packaging. This enhances portability.
5.2 Parallel Operation (Optional)
The iGen5000DFcv is parallel capable, allowing you to connect two compatible Westinghouse inverter generators to combine their power output. This requires an additional inverter generator and a parallel cord (sold separately).

Refer to the parallel kit's instructions for detailed connection procedures.
6. Operating Instructions
6.1 Starting the Generator (Recoil Start)
- Ensure the generator is on a level surface and all electrical loads are disconnected.
- Set the fuel selector to your desired fuel type (Gasoline or Propane).
- Turn the engine switch to the 'ON' position.
- If starting cold, apply choke as needed.
- Firmly grasp the recoil starter handle and pull it slowly until resistance is felt, then pull quickly and smoothly to start the engine. Repeat if necessary.
- Once the engine starts, gradually return the choke to the 'RUN' position.
6.2 Eco Mode Operation
The Eco Mode feature automatically adjusts engine speed to match the electrical load, optimizing fuel efficiency and reducing noise levels. To activate, simply press the 'Eco Mode' switch on the control panel. The indicator light will illuminate when active. For maximum power output, ensure Eco Mode is off.
6.3 Connecting Electrical Loads
Once the generator is running stably, you can connect your electrical devices to the appropriate outlets. The iGen5000DFcv features a 5-20R 120V Duplex Household Outlet, an RV-Ready TT-30R 30 Amp Outlet, and two USB Outlets. Always ensure the total wattage of connected devices does not exceed the generator's rated running wattage (3900 Watts).
7. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your generator. Refer to the detailed maintenance schedule in the full owner's manual for specific intervals.
- Engine Oil: Check oil level before each use and change regularly.
- Air Filter: Inspect and clean or replace the air filter as needed.
- Spark Plug: Inspect and clean or replace the spark plug periodically.
- Fuel System: Drain fuel if storing for extended periods to prevent fuel degradation.
8. Troubleshooting
If you encounter issues with your generator, consult this basic troubleshooting guide. For more complex problems, refer to the comprehensive owner's manual or contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel, incorrect choke position, low oil, spark plug issue | Check fuel level, adjust choke, add oil, inspect/replace spark plug |
| No power output | Circuit breaker tripped, overload, Eco Mode active (for full power) | Reset circuit breaker, reduce load, deactivate Eco Mode |
| Engine runs rough | Stale fuel, dirty air filter, dirty spark plug | Use fresh fuel, clean/replace air filter, clean/replace spark plug |
| CO Sensor shutdown | High carbon monoxide levels detected | Move generator to a well-ventilated outdoor area, allow to cool, restart |
