High Altitude Operation; Break-In Period; Low Idle; Before Starting The Generator - Westinghouse WGen20000 Manuel De L'utilisateur

3. Keep the bonded jumper wire in a secure location
so that the generator can be returned to the original
configuration.
IMPORTANT: Apply a new "NEUTRAL UNBONDED"
Label over the "NEUTRAL BONDED TO
FRAME" label on the front of the control
panel.

HIGH ALTITUDE OPERATION

Engine power is reduced the higher you operate above sea
level. Output will be reduced approximately 3.5% for every
1000 feet of increased altitude from sea level.
High altitude adjustment is required for operation at
altitudes over 5,000 ft. (1524 m). Operation without this
adjustment will cause decreased performance, increased
fuel consumption, and increased emissions.
DO NOT operate the generator at altitudes below 2,000
ft. (762 m) with the high altitude kit installed. Engine
damage may occur.
High Altitude Carburetor Kit Part# 518962-02

BREAK-IN PERIOD

For proper break-in, DO NOT exceed 50% of the rated
running watts (10,000 watts) during the first five hours of
operation.
Vary the load occasionally to allow stator windings to heat
and cool and help seat the piston rings.

LOW IDLE

ALWAYS start the generator with Low Idle OFF. Allow
the engine speed to stabilize before switching Low Idle
ON.
Frequency output of the generator is dependent on
engine speed. DO NOT use Low Idle when powering
sensitive electronics or large surge loads, such as an
air conditioner, electric pump, refrigerator, or when
connected to a home transfer switch.
Low Idle minimizes fuel consumption, noise, and engine
wear by lowering the engine RPM to idle (2400 RPM) when
electrical loads have been turned off and automatically
returns to rated speed when loads are turned back on.
Turn Low Idle ON when powering intermittent, non-
electronic loads, such as power tools at a construction site.

OPERATION

BEFORE STARTING THE GENERATOR

Verify that:
• The generator is placed in an safe, appropriate location.
• The generator is on a dry, flat, and level surface.
• The engine is filled with oil.
• All loads are disconnected.
Fire and explosion hazard. DO NOT move or tip the
generator during operation.

STARTING THE ENGINE

1. Verify that fuel is in the gas tank.
2. Turn the fuel valve to the ON position.
3. For a cold engine, pull the CHOKE knob fully out to the
full choke position. To restart a warm engine, push the
CHOKE knob to the half choke position or to the RUN
position.
4. Turn the engine start switch to the START position and
hold it there until the engine starts.
Note: If the engine fails to start after 5 seconds, release
key and wait 10 seconds before attempting to start
again. Cranking the electric starter for more than 15
seconds continuously can overheat and damage
the starter motor. If engine fails to start, wait for 1
minute to re-start. If the cranking speed drops after
multiple unsuccessful starting attempts, the battery
may not be adequately charged. See BATTERY
MAINTENANCE
5. Release the key when the engine starts.
6. When the engine starts, allow the engine to warm up
and then push the CHOKE knob fully inward to RUN
position.
