PREFACE Thank you for purchasing a Wanco portable generator set. This manual contains important safety and operating information - please read the complete manual before attempting to operate the generator. All information in this publication is based on the latest product information available at the time of approval for printing.
SAFETY INSTRUCTIONS Exhaust gas contains invisible but poisonous carbon monoxide. Never run the generator in an enclosed area. Gasoline vapor is invisible but extremely flammable and explosive under certain conditions. Shut the engine OFF and allow the generator to cool for two minutes before refueling. Never refuel while the engine is running.

Engine exhaust is very hot. Place the generator at least three feet or one meter away from buildings or other equipment during operation. The muffler becomes very hot during operation and remains hot for several minutes after stopping the engine. Be careful not to touch the muffler while it is hot. Let the engine cool before storing the generator indoors.
UNBOXING AND ASSEMBLY Wheel Kit Installation The unit comes with the rubber mounting feet installed. If you wish to install the wheel kit, please perform the following procedure. Parts Included: Axle assembly (1) Locking swivel wheel (2) Bolt M8X16 (4) Wheel (2) Bolt M6X16 (8) Wheel assembly:...
The generator serial number identifies your particular unit and is important when ordering parts and accessories. The number is engraved on the engine block beside the oil drain port (inside the service door). We recommend recording the following information in case you need to contact Wanco Technical Support: Model Number: WI______________ Serial Number: _________________...
SJ or higher. Select the appropriate viscosity for the expected temperature in your area. 10W – 30 oil is suitable for most climates. DO NOT use synthetic oil in Wanco inverter generators. Use of synthetic oil can interfere with break-in and can lead to excessive oil consumption.
Running the engine with insufficient oil can cause serious engine damage. The Low Oil Alarm Shutdown will automatically stop the engine before the oil level falls below a safe limit. However it is still advisable to visually inspect the oil level regularly. Fuel Use regular automotive gasoline with no more than 10% ethanol.
DO NOT connect a Wanco inverter generator to a building through a Double Throw Transfer Switch as it may damage the inverter. Only connect loads directly to the generator using extension cords.

The neutral conductor in this generator is bonded to the generator frame (“bonded neutral”). Follow local codes regarding grounding of portable generator sets, depending on how it is used. The total wattage of all appliances connected must be considered. Do not exceed the current limit specified for any one receptacle. Do not exceed the total power available from the generator.
GFCI protects against ground faults and is completely unrelated to overloads. The WI3000P generator also includes a thermal type circuit breakers to protect the GFCI receptacle from excessive current (more than 20 amps). This breaker has a small round button that extends when an overload condition is detected.
Air Conditioning Operation For best results, the Smart Throttle switch should be in the off position. Bring the generator to normal operating temperatures before applying the air conditioning load. Always allow a 2 minute wait period when manually cycling an air conditioner off and on. A longer wait period may be required under unusually hot weather conditions.
The system seamlessly matches frequency and evenly distributes the load to each generator so one is not overloaded. A 3000W Wanco inverter should only be paralleled with another 3000W Wanco inverter. Wanco offers two parallel kits (sold separately). WPK30 has a single 30A locking receptacle ideal for powering large loads such as RV air conditioners.
Parallel operation procedure: Do not attempt to connect running generators in parallel. Damage to the generators may occur. Turn off both generators and disconnect all the electrical devices from the generators Connect the parallel kit to each generator by inserting a pair of leads plus ground wire from the parallel box to the parallel receptacles and ground lug on the panel.
Maintenance Schedule REGULAR SERVICE PERIOD Perform at 3 MO 6 MO every indicated monthly or operating hour 300H interval whichever occurs first 100H ITEM ○ Engine oil Check ○ Change ○ Air cleaner Clean ○ Replace ○ Spark plug Clean/Gap ○...
Spark Plug Service To ensure proper engine operation, the spark plug must be the correct part, properly gapped and free of deposits. Open the generator service door. Remove the spark plug cap. Clean any dirt from around the spark plug base. Use the wrench to remove the spark plug.
Tighten the drain screw securely. Change the engine oil. TROUBLESHOOTING Basic troubleshooting steps are outlined below. If your generator still does not perform correctly after confirming these steps, you should contact Wanco to locate an Authorized Service Dealer. Page | 19...

If the Output Indicator Light is OFF and the Overload Indicator Light in ON, contact Wanco to locate an Authorized Service Dealer. If there is no voltage at the 12VDC receptacle, shut off the generator and remove the control panel to inspect the 12VDC fuse.
