Brief descriptions of the controls used during installation are:
A ‑ Circuit Breaker — Must be ON to supply power
to the transfer switch. Breaker enclosure includes
removable bottom panel to assist with conduit
connections.
B ‑ Set Exercise Switch — Used to set exercise cycle
start time.
C ‑ Manual Over‑Ride — Used to manually start and
stop the generator.
D ‑ 15 Amp Fuse — Protects DC control circuits.
E ‑ System Switch — Switches modes to OFF
or AUTO.
F ‑ Digital Display — Displays running time in hours or
fault codes.

System Switch
This two-position switch is the most important control on
the residential 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 residential 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. Periodically check coolant level as described
in the engine manual.
