WARNING
Electrical connections must be made by a trained and experienced electrician. Improper
installation can lead to electrocution and damage to property. Automatic startup of the generator
set during installation can cause severe personal injury or death. Push the control switch Off and
disconnect the negative (–) cable from the battery to keep the generator set from starting.
An optional thermostatically controlled battery heater is available for more reliable starting in
ambient temperatures down to -20 °F (-28.8 °C). The heater wraps around the battery. The
heater cord is connected in the 120V junction box.
An optional thermostatically controlled oil and alternator heater assembly is also available for
more reliable generator starting at low ambient temperatures. The heater cord is connected in
the 120V junction box.
