TESTING UNDER LOAD

Apply electrical loads equal to about 75 to 100 percent of the unit's
rated wattage/amperage capacity.
Let the unit run at least 30 minutes with load applied. During this
part of the test, check that the unit is not running excessively hot
and that adequate cooling airflow is available. Do not allow the unit
to overheat during prolonged operation.
The generator engine is equipped with a high temperature
switch. The switch has normally open (N.O.) contacts. When the
engine temperature is too high, switch contacts close, and the
engine shuts down automatically.
THE MANUFACTURER RECOMMENDS THAT THE GENERATOR
BE TESTED FOR ADEQUATE COOLING.
