4.5 High altitude operation
At higher altitudes, the standard carburetor air-fuel mixture will be excessively rich. Performance will
decrease, and fuel consumption will increase. Power output will decrease 3.5% for each 1000 feet (305 m)
above sea level.
High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburetor. If
you always operate the generator at altitudes higher than 5000 feet (1500 m) above sea level, have your
authorized dealer install a high altitude main jet.
Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 1000
feet (305 m) increase in altitude. The affect of altitude on the horsepower will be greater than this if no
carburetor modification is made.
■Operation of the generator at an altitude lower than the carburetor is jetted for
may result in reduced performance, overheating, and serious engine damage
caused by an excessively lean air/fuel mixture.
■Be sure to have any modification reversed at lower altitudes.
Temperature
High temperature adversely affects generator operation. Generator performance will decrease 1% for each
10°F (5.5°C) increase in temperature above 85°F (29°C). The normal operating range of this generator is
-20° to 113° F (-29° to 45°C).
■Do not operate the generator when the ambient temperature is below -20°F
(-29°C).
■Do not operate the generator when the ambient temperature exceeds 113°F
(45°C).

20 PH2100PRi OM revision 2010-10-07
4.6 Generator use
Be sure to ground the generator when loads are connected.
■To prevent electrical shock from faulty appliances, the generator should be
grounded. Connect a length of heavy cable between the generator's ground
terminal and an external ground source.
■Connections for standby power to a building's electrical system must be made by
a qualified electrician and must comply with all applicable laws and electrical
codes. Improper connections can allow electrical current from the generator to
back feed into the utility lines. Such back feed may electrocute utility company
workers or others who contact the lines during a power outage. When utility power
is restored the generator may explode, burn, or cause fires in the building's
electrical system.
■Do not connect the generator to an automatic transfer device. Severe damage to
the inverter module may result.
