The environmental condition required to operate the generator:
·Suitable temperature: -15
℃
-40
℃
.
·Suitable humidity: lower than 95%.
·Suitable altitude: under 1,000 meters (The power load should be reduced where the generator is
used at altitudes greater than 1000 meters.)
The generator unit can only be loaded to the rated power under the specified environment
conditions. If the environment conditions are inconsistent with the above standards, or if the
cooling conditions of the engine and generator unit are poor; for example, when operating
in enclosed areas, it is necessary to reduce the power load. It is also necessary to reduce the
power load when the temperature, altitude or relative humidity exceed the standards.
If
t
he generator does not
w
ork properly in optimal conditions, please take to the nearby
dealer or after-sales service center for inspection.
