Westinghouse WGen9500DF - Digital Inverter Generator Manual

Fire and electrocution hazard. Do not connect to a building's electrical system unless the generator and a transfer switch have been properly installed and the electrical output has been verified by a qualified electrician. The connection must isolate the generator power from utility power and must comply with all applicable laws and electrical codes. Failure to properly isolate the generator power could cause property damage and create a dangerous back feed of electricity which could kill or seriously injure utility workers.

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.

Familiarize yourself with all the instructions, safety warnings, illustrations, and specifications provided with this product. Failure to follow the manufacturer's instructions may result in electric shock, fire, and/or carbon monoxide poisoning that can lead to death or serious injury.

GROUNDING
See Figure 3.

Shock hazard. Failure to properly ground the generator can result in electric shock.
NOTICE
Only use grounded 3-prong extension cords, tools, and appliances, or double-insulated tools and appliances.
The generator neutral is bonded to the frame. There is a permanent conductor between the generator (stator wire) and the frame. If this generator will be used only with cord and plug equipment connected to the receptacles mounted on the generator, National Electric Code does not require that the unit be grounded. However, other methods of using the generator may require grounding to reduce the risk of shock or electrocution.

SAFETY PRECAUTIONS FOR GASOLINE AND GASOLINE VAPOR

Fire and explosion hazard. Gasoline is highly explosive and flammable and can cause severe burns or death.

Fire and Burn Hazard. NEVER loosen or remove the fuel cap while the generator is running. Turn the unit off and allow it to cool for at least five minutes before adding gasoline. Loosen the fuel cap slowly.

In case of a gasoline fire, do not attempt to extinguish the flame unless the engine/fuel control switch is in the OFF position. Introducing an extinguisher to a generator with an open fuel switch could create an explosion hazard.

• Fire Hazard. Gasoline is highly flammable. Handle with care.
• Never use gasoline as a cleaning agent.
• Gasoline is a skin irritant and needs to be cleaned up immediately if it comes in contact with the skin.
• Do not store gasoline near furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions.
• Keep gasoline away from sparks, open flames, pilot lights, heat, and other sources of ignition.
• Store any containers containing gasoline in a well-ventilated area, away from any combustibles or source of ignition.

• ALWAYS store gasoline in a container approved for gasoline. Unapproved containers can break or deteriorate allowing gasoline or gasoline vapors to escape which can create a serious hazard.
• Gasoline has a distinctive odor, this will help detect potential leaks quickly.
• Gas vapors can cause a fire if ignited.
• Do not smoke when handling fuel, adding fuel to the generator, or emptying the gas tank.
• Wear eye protection while refueling.
• Before adding fuel to the generator, turn the unit off and allow it to cool a minimum of five minutes. If necessary, move the unit to level ground.
• Do not remove the fuel tank cap when the generator is running.
• Loosen the fuel cap slowly to safely release pressure, keep gasoline from escaping around the cap, and to avoid the heat from the muffler igniting fuel vapors.
• NEVER fill the generator's gasoline tank beyond the maximum fill ring on the fuel screen. Keeping gasoline levels at or below the fill ring will allow for fuel expansion. 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. Wipe up spills immediately and allow area to dry before operating the generator. NEVER attempt to burn off spilled fuel.
• Securely tighten the fuel cap after adding gasoline.
• Do not cover the fuel cap while the generator is in operation. Covering the cap may cause the engine to fail or damage the product.
• Drain fuel before storing the unit. Store the unit and the fuel separately in well-ventilated areas away from sparks, open flames, pilot lights, heat, and other sources of ignition.
• Turn the unit off and allow it to cool a minimum of 30 minutes before draining fuel.

LIQUID PETROLEUM GAS (LPG/PROPANE)

Fire and explosion hazard. Never use a gas container, LPG/propane hose, propane cylinder or any other fuel item that appears to be damaged. If there is a strong smell of propane while operating the generator, fully close the propane cylinder 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.

Fire and explosion hazard. Only use approved Propane cylinders 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 cylinder 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.
• In case of a LPG/Propane fire, DO NOT attempt to extinguish the flame if the fuel valve is in the gas position. Introducing an extinguisher to a generator with an open fuel valve could create an explosion hazard.
• 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. If there is a smell, DO NOT use the engine.
• Always keep a propane cylinder in an upright position.
• When exchanging propane cylinders, be sure the tank valve is the same type.
• LPG/propane will burn the skin. Prevent skin contact at all times.
• Keep the propane cylinder away from the generator exhaust.
• Large (500 – 1,000 gallon) propane cylinders 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 in. to 14 in. of water column. A certified plumber must ensure that the pressure is correct or install a step down regulator if needed.
• Make sure the generator and propane cylinder 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 a propane cylinder near the engine exhaust.

• When transporting, make sure the propane cylinder and LPG/propane hose are not attached to the generator.
• Store propane cylinder away from sparks, open flames, pilot lights, heat, and other sources of ignition.
• Do not store propane cylinder near furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions.

LEAK TESTING
See Figure 5.

1. Leak testing with soapy water (propane)

NOTICE
Connections on the hose and the propane inlet were tested at the factory to make sure there were no gas leaks. However, shipping and handling may have loosened connections. We recommend that you always test for leaks before using the generator.

To test for LPG/Propane leaks:

• Connect the LPG/propane hose to the propane inlet on the generator and to the cylinder valve.
• Open the cylinder valve. If you hear a rushing sound, immediately turn off the cylinder valve. This noise indicates a significant leak at the connection. Replace the cylinder or have it repaired.
• Brush the inlet, hose connections, and LP gas cylinder with a soapy solution made of a 20/80 mixture of mild soap and water.
• If bubbles begin growing, there is a leak.
  • If the leak is at the inlet, contact customer service. DO NOT USE THE GENERATOR.
  • If the leak is at the hose connections, reinstall the hose securely and perform the check again. If the leaks persist, DO NOT USE THE GENERATOR.
  • If the leak is at the cylinder, do not use or move the cylinder. Contact the fire department or the gas supplier.
