Introduction
This manual provides essential information for the safe and efficient operation, maintenance, and troubleshooting of your Gidrox 11000W Dual Fuel Inverter Generator. Please read this manual thoroughly before operating the generator and keep it for future reference. Proper use and maintenance will ensure optimal performance and longevity of your unit.
Safety Information
Operating a generator can be hazardous if safety precautions are not followed. Always prioritize safety to prevent injury or damage.
General Safety Guidelines:
- Carbon Monoxide Hazard: Generators produce carbon monoxide (CO), an odorless, colorless, and deadly gas. Operate the generator outdoors only, far away from windows, doors, and vents. Never operate it inside a home, garage, basement, crawl space, or other enclosed area.
- Electrical Shock Hazard: Never operate the generator in wet conditions. Ensure all electrical connections are dry and properly insulated. Do not touch the generator with wet hands.
- Fire Hazard: Fuel is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the generator or fuel. Store fuel in approved containers.
- Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid touching hot surfaces to prevent burns.
- Children and Pets: Keep children and pets away from the generator at all times.
Integrated Safety Features:
- CO Sensor: The built-in CO sensor automatically shuts down the unit if dangerous levels of carbon monoxide are detected. This is a critical safety feature, but it does not replace the need for proper ventilation.
- Low Oil Auto-Shutdown: The generator will automatically shut down if the engine oil level drops below a safe operating threshold, protecting the engine from damage.
- Overload Protection: This feature prevents damage to the generator and connected appliances by automatically shutting off power if the electrical load exceeds the generator's capacity.
- Overvoltage Protection: Safeguards connected electronics from voltage spikes.

Setup and First Use
Before operating your generator, follow these steps for initial setup.
1. Unboxing and Inspection:
- Carefully remove the generator and all accessories from the packaging.
- Inspect the unit for any shipping damage. Contact customer support immediately if damage is found.
- Verify all included components are present: LPG hose, engine oil, dust cover, various plugs (NEMA 5-20P, NEMA L14-30P, NEMA 4-50P 50A, NEMA L14-30P to TT-30A), oil dipstick, and spark plug socket wrench.

3. Add Engine Oil:
- Place the generator on a level surface.
- Remove the oil fill cap/dipstick.
- Using the provided funnel, slowly add the recommended engine oil (0.36 gallons) until it reaches the upper mark on the dipstick. Do not overfill.
- Securely replace the oil fill cap/dipstick.

4. Add Fuel:
The Gidrox 11000W generator is dual-fuel capable, operating on either gasoline or propane.
For Gasoline Operation:
- Ensure the generator is off and cool.
- Open the fuel tank cap.
- Carefully pour fresh, unleaded gasoline into the fuel tank (8.7 gallons capacity) up to the fill line. Do not overfill.
- Securely close the fuel tank cap.

For Propane (LPG) Operation:
- Ensure the generator is off and cool.
- Connect the provided LPG hose to the generator's inlet connector and to a standard propane tank.
- Ensure all connections are tight to prevent leaks.
- Open the valve on the propane tank.

- Engine Start/Stop: Push-button electric start.
- Digital Panel Meter: Displays voltage, frequency, and runtime.
- Circuit Breakers: Protect outlets from overload.
- ATS.SW (ATS Switch): For connecting to an Automatic Transfer Switch.
- Charging Port: DC 12V output.
- Inlet Connect (LPG): For propane fuel connection.
- Fuel Switch: Selects between gasoline and propane.
- AC Outlets: Includes 120V 20A GFCI, 120V/240V 30A, and 120V/240V 50A outlets.
- CO Sensor: Carbon monoxide detection.
- Ground: Grounding terminal.
Starting the Generator:
- Ensure the generator is on a level, outdoor surface, away from any enclosures.
- Confirm sufficient oil and fuel (gasoline or propane) are present.
- Select the desired fuel type using the Fuel Switch.
- Turn the ENG.SW to the "ON" position.
- Press the Engine Start/Stop button for electric start. If the battery is low, use the manual recoil start.
- Allow the engine to warm up for a few minutes before connecting electrical loads.
