Operation
Important Owner’s Considerations
Engine Oil
This engine is shipped from the factory pre-run and filled
with non-synthetic oil (API SL 10W-30W). This allows
for system operation in a wide range of temperature and
climate conditions. Before starting the engine, check oil
level and ensure that engine is serviced as described in the
Maintenance section.
Coolant System
This engine is shipped from the factory filled with a
50-50 mix of automotive (ethylene glycol) anti-freeze and
water. This will provide optimum year round protection
against freezing, boiling and corrosion.
Battery
The installer must supply a valve-regulated, rechargeable
12 volt DC starting battery. See Battery in Final Installation
Considerations in the installation manual.
15 Amp Fuse
The generator’s 15 Amp fuse is critical to correct system
operation. The 15 Amp fuse was removed at the factory to
prevent the unit from starting during shipping. Your installer
will ensure the fuse is properly installed upon completion of
the installation.
NOTICE Any attempt to crank or start the engine before it
has been properly serviced with the recommended coolant
or oil will result in equipment failure.
• Refer to the Maintenance section for coolant and oil fill
information.
• Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.
WARNING Battery posts, terminals and related
accessories contain lead and lead compounds - chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
Automatic Operation
The generator’s control board constantly monitors utility
voltage. Should utility voltage drop below a preset level, the
control board will signal the engine to crank and start.
When utility voltage is restored above a preset voltage level,
the engine is signaled to shut down.
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board,
as follows:
Utility Voltage Dropout Sensor
• This sensor monitors utility source voltage.
• If utility source voltage drops below about 70 percent
of the nominal supply voltage, the sensor energizes
a 3 second timer. The timer is used to ‘sense’
brown-outs.
• Once the timer has expired, the engine will crank
and start.
Utility Voltage Pickup Sensor
This sensor monitors utility voltage. When utility voltage is
restored above 80 percent of the nominal source voltage, a
time delay starts timing and the engine will go to engine cool-
down.
Engine Cool-down Timer
When utility power is sensed and the load transfers back to
the utility source, the engine will go into a cool down period
as described below:
• If the generator has run for MORE than 5 minutes,
once the utility transfer occurs, the engine will
continue to run for about 1 minute before shutting
down.
• If the generator has run for LESS than 5 minutes, once
the utility transfer occurs, the engine will continue to
run until 5 minutes has elapsed before shutting down.
