OPERATION 

BEFORE STARTING THE GENERATOR

STOP: BEFORE STARTING THE GENERATOR

Location Selection
Before starting the generator, avoid exhaust and location hazards by verifying:

• You have selected a location to operate the generator that is outdoors and well ventilated.
• You have selected a location with a level and solid surface on which to place the generator.
• You have selected a location that is at least 15 feet (4.5m) away from any building, other equipment or combustible material.
• If the generator is located close to a building, make sure it is not located near any windows, doors and/or vents.

DANGER

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide. This is a poison vou cannot see or smell.

NEVER use inside a home or garage, EVEN IF doors and windows are open. Only use OUTSIDE and far away from windows, doors, and vents.

Avold other generator hazards. READ MANUAL BEFORE USE.

Weather
Never operate your generator outdoors during rain, snow or any combination of weather conditions that could lead to moisture collecting on, in or around the generator.
Dry Surface
Always operate the generator on a dry surface free of any moisture.
No Connected Loads
Make sure the generator has no connected loads before starting it. To ensure there are no connected loads, unplug any electrical extension cords that are plugged into the control panel receptacles.

Grounding the Generator
The National Electric Code  (NEC), as well as many local electrical codes, may require the generator to be connected to earth ground. The most common application that requires a ground rod is when you are using the generator as a separately derived system to provide back up power to your house. Typically this is when a transfer switch has a switched neutral.

As the generator application has many variables that cannot be determined by the manufacturer of the generator, a licensed electrician will need to determine if a grounding rod is needed.  If a licensed electrician has determined the application requires a ground rod, make sure it is connected to earth ground by connecting the ground terminal on the control panel to earth ground using copper wire (minimum 10 AWG). Consult a qualified electrician for local grounding requirements.
Neutral Bonded: There is a permanent conduct between the generator (stator winding) and the frame.

High Altitude Operation

Engine power is reduced the higher you operate above sea level. Output will be reduced by approximately 3.5% for every 1000ft of increased altitude from sea level. This is a natural occurrence and cannot be adjusted by engine. Increased exhaust emissions can also result due to increased fuel mixture. Other issues include hard starting, increased fuel consumption and spark plug fouling.

POWERCORD

Using Extension Cords
Westinghouse Portable Power assumes no responsibility for the content within this table. The use of this table is the responsibility of the user only. This table is intended for reference only. The results produced by using this table are not guaranteed to be correct or applicable in all situations as the type and construction of cords are highly variable. Always check with local regulations and a licensed electrician prior to installing or connecting an electrical appliance

Using Westinghouse Power Cord

Use the extension cord chart to determine the size of the conductor for extension cord applications. Determine the distance of the generator to the appliance on the top line of the chart. Then select the rated amperage of the generator on the left side of the chart. Where the two meet is the size of the conductor required for the application.

When using the WCG25/WCG20 power cord (sold separate) connect to the 120/240V outlet. The opposite end of the power cord is a fan tail receptacle with  2 green receptacles and 2 red receptacles. Each receptacle is rated at 120 volts AC. To balance the load on the generator’s alternator, use the red and green identifiers on the fan tail receptacle. To keep the load balanced, connect the loads so that both color receptacles are used. An example is one in red and one in green. Do not connect 2 in red and none in green, or 2 in green and none in red. If only one color receptacle is used with multiple loads, the alternator may experience an unbalanced load, causing undue vibration to generator.

CONNECTING THE GENERATOR TO A BUILDING ELECTRICAL SYSTEM

It is recommended to use a manual transfer switch when connecting directly to a buildings electrical system. Connecting a portable generator to a buildings electrical system must be made in strict compliance with all national and local electrical codes and laws, and be completed by a qualified electrician. 

TRANSFER SWITCH CONNECTIONS

• The Westinghouse generator is wired with the neutral bonded to ground. If you are connecting your generator to a panel board transfer switch, a licensed electrician will need to consider removing the bonded neutral to ensure proper operation of household GFCI circuits. Begin by removing the alternator cover (18 on page 14). Once the cover is off remove the nut that holds the bonded ground jumper wire (see “2” in Figure 6). Once the nut is removed take the bonded jumper wire off and re-secure the nut. Next, remove the screw holding the neutral ground wire (see “1” in Figure 6). Attach the bonded jumper wire (2) to the neutral ground (1) and tighten the screw. 

• If the bonded neutral is removed the generator must be relabeled as floating neutral on the control panel.

• If your generator is equipped with GFCI receptacles, removing the bonded neutral may not allow proper operation of the GFCI receptacles. Always keep the jumper wire in case it is needed for future use when not connected to a transfer switch.

  

ADDING / CHECKING ENGINE FLUIDS AND FUEL

STOP: BEFORE ADDING/CHECKING ENGINE FLUIDS AND FUEL.

Before starting the generator, always check the level of:

• Engine oil
• Gasoline in the fuel tank

Once the generator is started and the engine gets warm, it is not safe to add gasoline to the fuel tank or engine oil to the engine while the engine is running or the engine and muffler are hot.

CHECKING AND / OR ADDING ENGINE OIL

The unit as shipped does not contain oil in the engine. You must add engine oil before starting the generator for the first time. See Checking Engine Oil and Adding Engine Oil on page 26 for instructions on checking engine oil level and the procedure for adding engine oil.

STOP: ADDING GASOLINE TO THE FUEL TANK BEFORE ADDING GAS TO THE TANK.

Required Gasoline
Only use gasoline that meets the following requirements:

• Unleaded gasoline only
• Gasoline with maximum 10% ethanol added
• Gasoline with an 87 octane rating or higher

Filling the Fuel Tank
Follow the steps below to fill the fuel tank:

1. Shut off the generator.
2. Allow the generator to cool down so all surface areas of the muffler and engine are cool to the touch.
3. Move the generator to a flat surface.
4. Clean area around the fuel cap.
5. Remove the fuel cap by rotating counterclockwise.
6. Slowly add gasoline into the fuel tank. Be very careful not to overfill the tank. The gasoline level should NOT be higher than the filler neck (see Figure 7).
7. Install the fuel cap by rotating clockwise until you hear a click, indicating the cap is completely installed.

CONNECTING TO STANDARD LPG/PROPANE TANK

STOP: BEFORE CONNECTING PROPANE TANK TO THE GENERATOR.

Connecting LPG Tank

1. Make sure the generator is off, on a flat surface in well ventilated area.
2. Make sure propane tank valve is in the off position.
3. Make sure the fuel selector switch on the generator control panel is pointing downward to “Propane”. 
4. Remove the plastic cover on the generator propane inlet valve.

5. Using your fingers tighten the LPG hose (included) end below to the generator propane inlet. DO NOT OVER-TIGHTEN 35-88 Ib-in maximum.

   

6. Attach the other end of the hose to a tank of LPG/Propane and hand tighten.
7. Check all connections for leaks by wetting the fittings with soapy water. Anywhere that bubbles appear or grow indicates a leak in the connection. If a leak exists at a fitting then turn off the tank valve and tighten the fitting. Turn the gas back on and recheck with soapy water again. If the leak continues or if the leak is not at a fitting then do not use the generator and contact customer service.

NOTICE

1. When using standard 20 or 30 pound capacity LPG tanks, make sure they have Type 1, right hand Acme threads.
2. Verify the requalification date on the tank has not expired.
3. All new tanks must be purged of air and moisture prior to filling. Used tanks that have not been plugged or kept closed must also be purged
4. The purging process should be done by a LPG supplier. (Tanks from an exchange supplier should have been purged and filled properly already)
5. Always position the tank so the connection between the valve and the gas inlet won’t cause sharp bends or kinks in the hose.

CONNECTING TO LARGE LPG/PROPANE TANK

You can hook up you Duel Fuel Generator to a large home LP tank. It is required that you consult a plumber to properly connect your generator to the tank. 
To properly connect with a large propane tank you must first check and confirm the LP fuel pressure at the outlet of the LP tank. The LP fuel pressure should be 14-10” of water column, which is the standard fuel pressure for residential gas fired appliances.
If the LP fuel pressure is within the 14-10” water column range, the primary fuel regulator should be removed from the fuel line components. Then plumb directly from the LP tank to the secondary regulator assembled to the generator.

BEFORE STARTING THE GENERATOR

Before attempting to start the generator, verify the following:

• The engine is filled with engine oil. 
• The generator is situated in a proper location.
• The generator is on a dry surface.
• All loads are disconnected from the generator.
• The generator is properly grounded the Generator.
• Propane connection is secure with no leaks or damage. See Connecting LPG TanK.

SWITCHING FUEL SOURCES 

The below assumes that the propane fuel line is already attached to the generator securely and safely.
While the unit is running simply turn the FUEL SELECTOR knob to the desired fuel source. If you want to switch from gasoline to propane make sure the propane tank valve is open before you switch. When you move from propane to gasoline shut the propane valve after you have switched to gas. 

PROGRAMMING THE GENERATOR FOR REMOTE START

The generator can be started remotely from up to a maximum of 109 yards (100 M) away using the remote start key fob with new, fully charged batteries in the key fob. As the batteries’ state of charge in the key fob reduces, the distance to start the generator will also reduce.
Before the generator can be started, an initial start-up procedure must be performed so the generator and the key fob recognize each other. If the key fob is replaced, you will need to go through this procedure with the new fob.

1. With the battery connected, turn the engine control switch to the RUN position. The yellow battery light will illuminate.
2. Push and hold the red REMOTE PAIRING button on the side of the control panel until the push button start (3) on the control panel illuminates red, then let go (see 17 on page 13 for location of button).
3. Press and hold the STOP (2) button on the remote start key fob until the red light on the push button start (3) goes out, then let go.
4. Press and hold the START (1) button on the remote start key fob until the red light on the push button start (3) goes out, then let go.

5. Press and hold the REMOTE PAIRING button until the red light on the push button start (3) goes out. The generator is now programmed to start remotely.

   

POWER OUTPUT AND DEMAND
The generator should not be run completely unloaded for extended periods otherwise the engine may be damaged. It is recommended that the generator should always be operated with at least one-third of its rated 120-Volt AC power output. 120-Volt AC devices have two different electric power demands that must be taken into consideration, namely the running power and the starting/peak power. Both are measured in Watts (typically abbreviated as “W”).

The steady state continuous load is the running power demand and this is often marked on the device near its model number or serial number. Sometimes the device might only be marked with its voltage (i.e. 120 V) and current draw (e.g. 6 Amp or 6 A), in which case the running power demand in Watts can be obtained by multiplying the voltage times the current, e.g. 120 V × 20 A = 2,400 W.

Simple resistive 120-Volt AC devices such as incandescent bulbs, toasters, heaters, etc. have no extra power demand when starting, and so their starting power demands are the same as their running power demands.

More complex120-Volt AC devices containing inductive or capacitive elements such as electric motors have a momentary extra power demand when starting, which can be up to seven times the running power demand or more. Manufacturers  of such devices rarely publish this starting power demand and so it’s often necessary to estimate it. A rule of thumb  for devices fitted with an electric motor is to apply a starting power multiplier of 1.2 for small hand-held or portable devices and a value of 3.5 for larger stationary devices. 

For example, a 900 W angle grinder can be assumed to have a starting power demand of at least 1.2 × 900 W, which equals 1,080 W. Similarly, a 1,650 W air compressor can be assumed to have a starting power demand of at least 3.5 × 1,650 W, which equals 5,775 W.
To prevent overloading of the generator’s 120-Volt AC system:

1. Add up the running power demand of all the 120-Volt AC devices that will be connected to the generator at one time. This total must not be greater than the generator’s specified running power output.
2. Add up the running power demand again, but for the largest motor-driven device use the value of its starting power demand instead of its running power demand. This total must not be greater than the generator’s specified starting power output.
3. The total running power demand of all the devices that will be connected to any one of the generator’s outlets must not exceed the generator’s specified running power output or 3,700 W, whichever is the lesser.

ELECTRIC START

Be sure to check oil levels before starting. If it is the first time starting make sure to add oil (see Adding Engine Oil page 26).

1. Make sure nothing is plugged into power outlets 
2. Verify the battery is properly installed and both battery cables are attached

3. Make sure the circuit breakers are properly set (see Figure 8).

     2. Turn fuel selector knob to GASOLINE (see Figure 9).

        

   • FOR LPG/PROPANE:
     1. Make sure the LPG hose is safely secured from the generator to the tank.

     2. Turn the fuel selector knob to PROPANE (see Figure 10).

        

     3. Fully open the valve on the propane tank.

5. Push the engine control switch into the RUN position

   

6. Push and hold the push button start until the generator starts, then release. If using remote start then hold down START on the remote key fob until the generator starts, then release.

   

   The engine will automatically set the choke and begin the start sequence.

   • If the engine has started successfully the light indicator on the engine start button will turn green.
   • If the engine fails to start, the generator controls will attempt to start the engine two more times for a total of three attempts.
   • If the third attempt fails, the light on the engine start button will turn red.
   • If the engine has failed to start after three attempts the push button start can be pushed again to begin the automatic start sequence.
   • The engine control switch can be switched at any time during the automatic start sequence to abort the engine start attempt.
     NOTE: If the cranking speed drops after each unsuccessful attempt, then the battery may not be adequately charged. You can alternatively start the generator using the recoil start as instructed in Manually Starting a Generator.

MANUALLY STARTING THE GENERATOR 
Be sure to check oil levels before starting. If it is the first time starting make sure to add oil.

1. Make sure nothing is plugged into power outlets
2. Make sure the circuit breakers are properly set (see Figure 8)
3. Select fuel source.
4. Push the engine control switch into the RUN position (see Figure 11).
5. Manually set the choke:

   1. Cold Start: Close the choke by moving it right towards the front handle of the generator.

6. Firmly grasp and pull the recoil handle slowly until you feel increased resistance. At this point, apply a rapid pull while pulling up and slightly away from the generator (see Figure 12).

   

7. Plug-in electric devices.

STOPPING THE GENERATOR

Normal Operation
During normal operation, use the following steps to stop your generator:

1. Remove any connected loads from the control panel receptacles.
2. Allow the generator to run at “no load” to reduce and stabilize engine and alternator temperatures.
3. Choose from options below to stop the generator (see Figure 13):
   • Position the engine control switch to STOP
   • Hold push button start until the generator stops
   • Hold the STOP button on the remote start key fob (Note: The generator will run for an additional 15 seconds as it goes through a cool down cycle before shutting off.)
     NOTE If you plan to store the generator after use, stop the generator by turning the fuel shutoff valve to the OFF position and allow the fuel to be consumed from the carburetor. 
4. If running off of propane then close the propane valve. If running on gas turn the fuel shutoff valve to the OFF position.

During an Emergency
If there is an emergency and the generator must be stopped quickly, position the engine control switch to the STOP position immediately.
