System Control Panel
The home generator control panel, located inside the
generator housing, is shown below.
Brief descriptions of the controls used during installation are:
A Removable Panel — To assist with conduit connection.
B Circuit Breaker — Must be ON to supply power to the
transfer switch.
C Set Exercise Switch — Used to set time of the exercise
cycle.
D Manual Over-Ride Switch — Used to manually start
and stop the generator.
E 15 Amp Fuse — Protects the DC control circuits.
F System Switch — Switches modes to OFF and AUTO.
G Digital Display — Displays running time in hours, and
fault codes.
H Voltage Regulator — Used to adjust generator output
voltage.
More information may be found in Controls in the Operator’s
Manual.
System Switch
This two-position switch is the most important control on
the home generator and is used as follows:
• “AUTO” position is the normal operating position. If
a utility power outage is sensed, the system will start
the generator. When utility power is restored, lets the
engine stabilize internal temperatures, shuts off the
generator, and waits for the next utility power outage.
• “OFF” position turns off running generator, prevents
unit from starting and resets any detected faults.
15 Amp Fuse
Protects the home generator DC control circuits. If the fuse
has ‘blown’ (melted open) or was removed, the engine
cannot crank or start. Replace the fuse using only an
identical ATO 15A fuse. One spare fuse is supplied with the
unit. If fuse was blown or removed, you will need to reset
the exercise timer (see Setting Exercise Timer).
Final Installation Considerations
Engine Oil
NOTICE
Any attempt to crank or start the engine before it has been
properly serviced with the recommended oil will result in
equipment failure.
Refer to Maintenance and engine manual for oil fill
information.
Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.

•
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 engine
operator’s manual.
Coolant System
This engine is shipped from the factory filled with a 50-
50 mix of automotive (Dex-Cool™ orange) anti-freeze and
water. This will provide optimum year round protection
against freezing, boiling and corrosion. The coolant system
incorporates a water heater that operates when ambient
temperature is below 80ºF AND utility power is present at
the transfer switch. Before starting the engine, check coolant
level as described in the engine operator’s manual.
